After five years of exploration, MPRL E&P made the first gas discovery (Pyi Thar-1 in 2012) in the Western Ayeyarwady Basin at its sole risk with its own funds. Woodside and Total became co-venturer in 2013 and 2015 respectively. The resulting second gas discovery was followed by three more gas wells in 2017-2018. Five out of five wells drilled in Block A-6 found gas and brought the joint venture within line of sight of commerciality. The joint venture is now striving to unlock the supply of a clean and long-term sustainable source of energy to drive the development of the nation.

Block A-6, covering nearly 10,000 km2 from the shore to more than 2,400 m water depth, only had some 1,330 km of old vintage 2D seismic data when MPRL E&P signed the production sharing contract in January 2007.

Since then, MPRL E&P undertook extensive geological studies which included four field study expeditions all along the Western Ayeyarwady coast and acquired nearly 2,000 km of 2D seismic in 2009. This was followed by the acquisition of the first 3D seismic survey in the block.

Pyi Thar-1, the first well drilled in the block which resulted in a gas discovery, was drilled in March 2012 in 200 m water depth. The well successfully identified a new petroleum play system consisting of sands deposited by what is believed to be ancient Ayeyarwady submarine river course (see “MPRL E&P’s Pyi Thar Gas Discovery – Realizing the Vision for Long-Term Sustainable Energy in Myanmar” and “Press Release of Well Pyi Thar-1”).

Attracted by this exciting find, Woodside farmed-in to the block in 2013 and the JV acquired a new 3D seismic survey over a large structure located in the ultra deep water region and first identified by MPRL E&P in its 2D seismic survey in 2009. Total joined the block A-6 joint venture in 2015.

A second gas discovery was achieved when Shwe Yee Htun-1, the second exploration well in the block, was drilled in late 2015 targeting a prospect over 5 km from the surface and in water depths of 2,034 m. This outcome has enabled the block to move into the appraisal phase. Shwe Yee Htun-1 also holds the record for the offshore well drilled in the deepest water depth in Myanmar. ( see “Press Release of Well Shwe Yee Htun-1″)

Another 3D seismic data acquisition campaign was undertaken in April 2016 whereby the joint venture is now aggressively planning for subsequent appraisal wells to be drilled with the intent towards rapidly understanding the commercial feasibility of the asset.

As a third gas discovery well, Pyi Thit-1 was drilled in ultra-deep waters of Block A-6 in June 2017. This well discovered gas in channel sands at shallower depth than Shwe Yee Htun-1 (2,001 m), with excellent reservoir quality which comforted the A-6 JV in the reliability of the seismic image. This well was tested and flowed 50 MMscf/d of gas, a rate which was constrained by the equipment of the drill-ship; pressure monitoring indicated access to a substantial pool of gas. (see “Press Release Well of Pyi Thit-1”)

Pyi Tharyar-1, as a fourth well in Block A-6, was drilled in August 2017 and targeted a much shallower play below sea bottom in deeper waters to the West. This well showed only 3 m of gas-bearing sands. This result, however, further reinforced the A-6 JV’s confidence in discriminating between gas and water-bearing sandstones using 3D seismic.

As a fifth gas discovery well, the Appraisal Well Shwe Yee Htun-2 has been successfully drilled in July 2018 with formation evaluation results indicating a gas column and net pay thickness that substantially exceeds prior expectations. Wireline formation evaluation including pressure measurements demonstrates that the reservoir is highly likely to be in pressure communication with the 2016 Shwe Yee Htun-1 discovery, which is approximately 10km east of the current drilling location. Drill stem test results indicate Shwe Yee Htun-2 achieving a flow rate of 50 million standard cubic feet per day (up to 53.7 million standard cubic feet per day) of gas limited by testing equipment through a 40/64″ choke. ( see “Press Release of Well Shwe Yee Htun-2″)

On 16 December 2019, MPRL E&P and its Block A-6 Joint Venture partners Woodside and Total, successfully executed two agreements with Myanma Oil & Gas Enterprise (MOGE). These agreements include the Fourth Amendment and Supplementary Agreement to the Production Sharing Contract and the Agreement on Upstream and Midstream Ratio. These agreements establish the necessary fiscal framework enabling the Block A-6 project to best achieve economic viability. They further provide a clear line of sight towards the commerciality of this ASEAN’s first ultradeep water gas development project with first gas targeted for 2023.

MPRL E&P continues to lead the offshore exploration sector by moving closer towards unlocking the gas potential of block A-6 in the form of a clean and long-term sustainable energy supply that Myanmar may leverage to drive progress in the nation.

Test Launch of Artificial Reefs and Coral Nurseries to Revive Marine Life

A landmark coral reef conservation project came to life near Sabahtar Island, Nga Yoke Kaung Town, as part of the MPRL A-6 PIP Corporate Social Responsibility (CSR) Program. In collaboration with the marine expert Dr. Cherry Aung from Myeik University and nine divers—including local volunteers and experienced professionals—the PIP CSR Team launched a test project for artificial reefs and coral nurseries to revive marine life in the waters surrounding the island.

The journey began on 12 October 2024, with the PIP CSR Team conducting land-based tests on the artificial reef and coral nursery structures. The air was filled with anticipation as each structure was carefully examined to ensure readiness for underwater deployment. The team finalized transportation logistics, ensuring everything was prepared for the next phase of the project.

Each artificial reef was constructed in a pyramid shape using 46 concrete blocks. These blocks, each weighing 23 kilograms and measuring 16 inches long, 8 inches wide, and 8 inches high, were assembled to form towering underwater habitats. In total, 184 blocks were used to build four structures, each standing 3.5 feet tall and 6 feet wide.

Local welders and masons played a vital role in creating the coral nurseries. They crafted sturdy frames with a 5-foot diameter, using thick iron rods, 50-kilogram concrete posts, and metal connectors. These frames will later hold coral fragments, promoting regeneration and reviving the reefs in the area.

As the divers submerged, the first three artificial reef structures were successfully deployed. Suspended by lift bags, the concrete blocks were carefully lowered to the seafloor. These reefs, designed to serve as breeding grounds for marine life, were positioned in areas carefully chosen to enhance the local ecosystem.

On 14 October 2024, the Project Team deployed the final artificial reef structure along with two coral nurseries. Coral fragments from nearby reefs were collected, sorted, and attached to the nursery frames. These fragments will soon grow and help restore damaged coral populations, contributing to the area’s ecological balance.

Saving the Rainforests of the Sea: A New Initiative to Protect Coral Reefs

As the global population climbs to an estimated 8.2 billion, the demand on our planet’s natural resources is more intense than ever. This milestone urges a deep reflection on human activities and their effects on the environment, raising the question of how long Earth can sustain such pressures. While much attention has been directed toward conserving terrestrial environments like rainforests, there is a growing need to address the conservation of their aquatic counterparts—coral reefs, often dubbed the “rainforests of the sea.”

Saving the Rainforests of the Sea: A New Initiative to Protect Coral Reefs

As the global population climbs to an estimated 8.2 billion, the demand on our planet’s natural resources is more intense than ever. This milestone urges a deep reflection on human activities and their effects on the environment, raising the question of how long Earth can sustain such pressures. While much attention has been directed toward conserving terrestrial environments like rainforests, there is a growing need to address the conservation of their aquatic counterparts—coral reefs, often dubbed the “rainforests of the sea.”

Coral reefs, despite covering just 0.1 percent of the ocean floor, are home to approximately 25 percent of all marine species. These ecosystems provide habitat, food, and breeding grounds for millions of marine organisms, supporting around a quarter of the world’s fish populations. Their significance is often compared to that of rainforests on land, which are equally rich in biodiversity and vital to the planet’s health.

The World Wildlife Fund (WWF) and the National Oceanic and Atmospheric Administration (NOAA) highlight the unparalleled diversity of life that coral reefs sustain. Hosting nearly a quarter of all ocean species, coral reefs are the most diverse habitats on Earth, providing sanctuary for countless species including fish, crabs, clams, starfish, squid, sponges, lobsters, seahorses, and sea turtles. According to the WWF, the economic and ecological benefits of these ecosystems are immense, contributing an estimated £300 billion annually to the global economy by protecting coastlines, supporting tourism, and providing food and livelihoods for millions of people.

In Myanmar, coral reefs are a keystone of the country’s fishing industry and an essential component of its marine biodiversity. The health of Myanmar’s coral reefs is directly linked to the sustainability of its marine fisheries, which are vital for the livelihoods of coastal communities. Moreover, these ecosystems support maritime tourism activities like snorkeling and scuba diving.

Myanmar boasts a coastline stretching over 2,800 km, divided into three main regions: the upper Rakhine Coast, the middle Ayeyarwady Coast, and the lower Tanintharyi Coast, all renowned for their rich coral reefs. The Myeik Archipelago, located off the Tanintharyi Coast, is renowned for its stunning coral reefs, which boast more than 500 recorded species. This biodiversity hotspot has been proposed as a UNESCO World Heritage Site and is part of Myanmar’s broader efforts to establish Marine Protected Areas (MPAs).

Despite their importance, coral reefs in Myanmar are facing severe threats. According to the International Coral Reef Initiative (ICRI), Myanmar’s coral reefs have declined by more than 56 percent, primarily due to the combined effects of climate change, destructive fishing practices, and unregulated resource extraction.

The Gaw Yan Gyi area in the Ayeyarwady Region is one such area where coral reefs are under threat. Known for its vibrant marine life, this area is also in urgent need of conservation efforts to preserve its rich coral ecosystems. Recognizing this need, MPRL A-6 Pyitharyar Integrated Project (PIP) CSR Program has embarked on a crucial initiative to protect Myanmar’s coral reefs. In 2023, the CSR Program launched a coral reef conservation pilot project named “Coral Revive” in the Gaw Yan Gyi area, near the proposed offshore Pyitharyar Integrated Project (PIP).

The pilot project began with a series of stakeholder engagement activities aimed at assessing the current state of coral reefs in the Gaw Yan Gyi area and identifying the causes of coral degradation. The CSR Team conducted extensive engagement activities before the project began, gathering insights from local fishermen, community leaders, civil society organizations, and tourism operators. These discussions highlighted several key themes, including the presence of numerous coral reefs in shallow waters near the project area, the causes of coral reef destruction, the lack of knowledge about coral conservation, and the challenges and opportunities for preserving these ecosystems.

One of the project’s cornerstone initiatives is the establishment of a locally managed coral reef conservation area around Sabahtar Island, near Gaw Yan Gyi Island. Set to run from 2024 to 2026, this two-year project aims to engage the local community in the conservation efforts, fostering a sense of ownership and responsibility for the protection of their natural resources.

On 03 April 2024, the project began with a Birds of a Feather (BoF) session, which served as both an information exchange and a workshop on coral reef conservation. The session was well-attended, with 40 participants, including members of the CSR Team, marine experts led by Dr. Cherry Aung, the Professor of Marine Science Department at Myeik University, and local stakeholders such as government representatives, fishermen, and community leaders.

The BoF session conducted a socioeconomic assessment survey of the coral reefs at Gaw Yan Gyi, which aimed to gain insights into the community’s perceptions, livelihoods, and resource management practices related to the coral reef ecosystem. The findings from this survey are expected to guide future conservation efforts and sustainable development initiatives in the area. The session also facilitated discussions with local stakeholders, leading to the development of a coral reef mapping initiative involving community members.

The day after the BoF session, the CSR Team coordinated a diving survey to further investigate and map the coral sites. This effort was crucial for establishing a foundation for targeted conservation initiatives. The surveys were designed to pinpoint the most at-risk areas and develop strategic approaches for their protection.

In July 2024, MPRL A-6 PIP CSR Program conducted a three-day diving training session for local volunteers as part of the coral reef conservation pilot project. Led by an experienced coach, the training focused on equipping participants with the necessary skills for safe and effective underwater conservation work. The curriculum included both theoretical and practical aspects of diving, with a strong focus on safety and the use of modern diving equipment.

Trainees, many of whom had previously used riskier compressor-based diving methods, gained valuable new skills that not only improved their safety but also empowered them to actively contribute to the conservation pilot project. As local fishermen, they recognized the critical role of coral reefs in sustaining their livelihoods and expressed strong commitment to the project’s success. This training not only enhanced their diving abilities but also fostered a sense of ownership and responsibility toward protecting their local marine environment.

The coral reef conservation pilot project in Gaw Yan Gyi is just the beginning of a broader effort to protect Myanmar’s marine ecosystems. In July 2024, the CSR Team held a series of meetings with the officials from the Forest Department, the Department of Fishery, the Environmental Conservation Department, and the Directorate of Hotels and Tourism at the Pathein Office. These discussions aimed to align conservation efforts with broader regional plans, including the development of diving sites and other locally managed marine areas.

On 23 July 2024, the CSR Team presented the coral reef conservation pilot project to the Chief Minister of the Ayeyarwady Region, detailing the activities undertaken so far and seeking official consent and guidance for the project. A concept proposal of the locally managed coral reef conservation area was subsequently submitted to the Chief Minister on 07 August 2024, following thorough discussions with the project team members and consultations with relevant government departments and community groups.

The coral reef conservation pilot project at Gaw Yan Gyi Island represents a significant effort to preserve Myanmar’s marine biodiversity. With the success of this project, MPRL A-6 PIP CSR Program hopes to extend its scope to other areas, such as Ngwe Saung in the Ayeyarwady Region. As the project progresses, it will serve as a model for other conservation efforts in the region.

Through continued collaboration and community involvement, MPRL A-6 PIP CSR Program is laying the groundwork for a future where Myanmar’s coral reefs can thrive, supporting both marine life and the livelihoods of those who depend on these vital ecosystems. Coral reefs, the “rainforests of the sea,” are vital to our oceans and our planet—preserving them is a responsibility we all share.

MPRL E&P’s Pyi Thar Gas Discovery – Realizing the Vision for Long-Term Sustainable Energy in Myanmar

How a small independent embraced the challenges of exploring frontier waters in a harsh business environment and made a momentous basin-opening gas discovery

In 2007, MPRL E&P was awarded the rights to explore Block A-6 located offshore in the Western Ayeyarwady coastal region in the Bay of Bengal. MPRL E&P undertook extensive geological field studies all along the coast of the Myanmar Bay of Bengal south of Sittwe, lining up a total of more than 400 days of geologists’ observations in expeditions and laboratory studies.

In 2009, MPRL E&P undertook to shoot more than 2,000 km of modern 2D seismic lines, including in ultra-deep waters, even knowing the company would never had the means of drilling in such depths. This 2D seismic was acquired to look for hints of deposits of gas similar to those discovered in areas such as in the deep waters of India on the other side of the Bay of Bengal, and with a vision that some partner with deep pockets would be able to invest in this expensive exploration game.

Having mapped some interesting teasers, MPRL E&P acquired the first ever exploration 3D seismic survey of the southern Western Ayeyarwady Basin, which threw light on exciting gas-telling features in the form of stacked bright seismic amplitude anomalies known by geologists as “bright spots”.

At this point MPRL E&P searched for investors to fund the drilling of the committed exploration well. Most of the initially interested companies expressed doubts that reservoir sands could be deposited in this environment, arguing that the results of wells drilled in the 1970’s were rather grim, with little sniffs of gas in elusive sandstones.

State enterprise MOGE meanwhile allowed for an extension of the initial exploration period at the condition of drilling two wells instead of one, at which point MPRL E&P obtained that this second well would be intentionally deviated from the original hole as a sidetrack, thereby saving substantial drilling costs.

The top image shows one of the Ayeyarwaddy River channels. These channels continue beyond the shores, as sands of the river pour into the sea. MPRL E&P discovered gas in sands of Pyi Thar-1 in the shallower water part of one of these channels while Shwe Yee Htun-1 hit gas in sands of the deep-water part of one channel.

MPRL E&P’s executive management was bold enough to trust its geoscience team and risk a substantial amount of MPRL E&P’s money considering the relatively small chance of success of finding gas and/or sands while drilling Pyi Thar-1.

MPRL E&P then seized the opportunity of the Korea National Oil Corporation (KNOC)’s Doo Sung semi-submersible drilling platform looking for a short job before sailing to her final destination, and in late February 2012, Pyi Thar-1 was initiated in 200 m of water depth. The vertical hole reached its intended depth of 4,500 ft in a record eight days and proved sands beyond expectation towards the bottom of the hole. One of the big unknown was solved: thick sands do exist in this province, these sands showed up to come from a branch of an ancient Ayeyarwaddy River flowing westwards until about a million years ago.

Just three days later, those same sands were crossed again by the drill bit in a sidetrack hole exceeding 45° in inclination, the upper part of which showing excellent gas readings in spite of rapid drilling. Extensive sampling confirmed the find before abandoning the well, 17 days ahead of a 40-day schedule and much under budget. Drilling success stands on three legs: good geological insights, excellent well design and planning as well as smooth and swift logistics and supply. MPRL E&P proved once again to be an extremely efficient operator, having designed, planned, tendered, implemented and drilled an offshore wildcat in a virtually virgin play in less than eight months between August 2011 and March 2012.

The efforts undertaken at MPRL E&P’s sole risk, with its own funds in a time of harsh economic sanctions depriving the country of state-of-the-art technology, resulted in the discovery of a world-class new gas province. Had MPRL E&P not discovered Pyi Thar-1, it can only be surmised that hardly any company would be exploring the Western Ayeyarwady Basin at present, and the area would have returned into geological neglect. Four years only after this momentous discovery, four majors have acquired some 35,000 km2 of 3D seismic in the 2015-2016 season in this new play alone. Meanwhile MPRL E&P and its partners Woodside and Total joining to tap into the Pyi Thar success story – made a second gas discovery in Block A-6 with Shwe Yee Htun-1 opening a door to commerciality in deep waters in January 2016, a third gas discovery with Pyi Thit-1 in June-August 2017 being a significant ultra-deep water gas discovery with tested flow rate of 50 MMscf/d of gas and successful drilling of exploration well Pyi Tharyar-1 in August 2017.
