Tatweer Petroleum: Bahrain’s Upstream Operator Now Bapco Upstream

Tatweer Petroleum ran Bahrain’s upstream oil and gas sector from 2009 until 2023, when it was rebranded as Bapco Upstream W.L.L. under the newly created Bapco Energies group. The company never disappeared — it was absorbed and restructured — but the Tatweer Petroleum brand is now retired, and its assets, staff, and mandate have transferred into Bahrain’s unified national energy holding company.

For anyone searching for Tatweer Petroleum in 2026, the operating entity is Bapco Upstream, a wholly owned subsidiary of Bapco Energies B.S.C., which also encompasses Bapco Refining, Bapco Gas, Bahrain LNG, and Bahrain Aviation Fueling Company (BAFCO).

What Was Tatweer Petroleum?

Tatweer Petroleum — formally the Bahrain Field Development Company W.L.L. — was established in December 2009 to take stewardship of the mature Bahrain Field (also known as the Awali Field), the country’s primary onshore producing asset and the first commercial oilfield to be developed anywhere in the Arabian Gulf. The field has been in continuous production since 1932.

The company was initially created under a Development and Production Sharing Agreement (DPSA) signed in April 2009 between Bahrain’s National Oil and Gas Authority (NOGA), Occidental Petroleum, Mubadala Development Company, and the state holding vehicle nogaholding. By July 2016, Tatweer Petroleum was wholly owned by nogaholding after Occidental and Mubadala exited.

Its mandate covered all upstream activity in the Kingdom: oil and gas exploration, development, production, and gas distribution. The Bahrain Field — a carbonate and sandstone reservoir system — is a mature asset requiring enhanced recovery techniques to maintain output, and Tatweer Petroleum’s operational focus was sustaining and incrementally growing production rather than greenfield development.

Tatweer Petroleum’s Production Scale

At its peak under the Tatweer name, the company produced approximately 57,000 barrels of oil equivalent per day from the Bahrain Field. This is a modest output by Gulf standards — Bahrain reached a crude production high of around 205,000 bpd in 2016 including the Abu Safah field operated by Saudi Aramco on Bahrain’s behalf — but the Bahrain Field itself has been kept commercially productive for over nine decades using waterflood, enhanced recovery methods, and a steady infill drilling programme.

Tatweer Petroleum invested consistently in new well completions and gas infrastructure. A Central Gas Dehydration Facility was commissioned during its operational period, and the company drilled unconventional crude production wells in partnership with international oilfield services companies. Gas distribution and sales were also within its remit — supplying feedstock to Bahraini industry as well as fuel for the domestic grid.

The Khalij Al Bahrain Discovery — and Why It Stalled

In April 2018, NOGA announced the discovery of the Khalij Al Bahrain Basin — an offshore tight oil and deep gas play covering approximately 2,000 square kilometres in shallow Gulf waters off Bahrain’s west coast. Independent appraisals by DeGolyer and MacNaughton estimated at least 80 billion barrels of tight oil in place and between 10 and 20 trillion cubic feet of deep gas. The announcement was the most significant upstream development in Bahrain’s history since the Awali discovery nearly a century earlier.

Tatweer Petroleum drilled the first KAB appraisal wells in 2019. However, by 2022, nogaholding confirmed that commercial development was not economically viable at that time — the combination of a technically challenging tight reservoir and an offshore location created cost barriers that current oil prices could not support. The KAB project was paused, with attention shifting to the Pre-Unayzah deep onshore gas formation as the more viable near-term development target.

In May 2025, Bapco Energies signed a strategic agreement with EOG Resources to commence unconventional gas drilling in the Pre-Unayzah formation — marking the first entry into deep onshore unconventional gas exploration in Bahrain, and the clearest signal yet of the post-Tatweer upstream strategy. The company also launched the largest-ever offshore 3D seismic survey in Bahrain in 2025, covering more than 4,000 square kilometres, using AI-driven subsurface imaging to guide future exploration priorities.

The 2023 Rebrand: Tatweer Petroleum Becomes Bapco Upstream

In May 2023, the Bahraini government inaugurated Bapco Energies as the new brand identity for nogaholding, consolidating the Kingdom’s energy operating companies under a single integrated group. Tatweer Petroleum was restructured into Bapco Upstream W.L.L., retaining its upstream mandate but operating as a named subsidiary within a larger corporate framework alongside Bapco Refining, Bapco Gas, and Bahrain LNG.

The rebrand reflected a strategic shift from a pure hydrocarbon holding structure toward a broader energy group with ambitions in renewables, carbon reduction, and downstream diversification. Bapco Energies has committed to generating 20% of Bahrain’s electricity from renewable sources by 2035 and achieving net-zero carbon emissions by 2060. The upstream division — Bapco Upstream — retains the core operational mission of the Tatweer era: maximising recovery from the Bahrain Field while building the infrastructure base for new gas development.

Bapco Upstream secured a significant infrastructure contract with Petrofac in late 2024 to connect new wells, install tie-ins, and develop gas flow infrastructure in the Bahrain Field — alongside a separate contract for a new gas dehydration facility to improve processed gas quality from mature reservoirs. These are continuations of the Tatweer Petroleum capital programme, now executed under the Bapco Upstream name.

Bahrain’s Upstream Position in 2026

Bahrain remains one of the smaller Gulf producers by volume. Its Abu Safah offshore field — operated by Saudi Aramco, with 50% of revenues transferred to Manama — is supplied via the historic A-B pipeline linking the Arabian mainland to Bahrain and contributes the majority of the country’s total oil production. The Saudi Aramco pipeline delivers approximately 350,000 barrels per day to the BAPCO refinery at Sitra, though the bulk of this crude is Saudi material processed on Bahrain’s behalf rather than indigenous Bahraini production.

The top-tier upstream players globally dwarf Bahrain’s domestic output, but the country punches above its weight in pipeline and refining infrastructure relative to its reserves base. The Sitra refinery — now operated by Bapco Refining with a TotalEnergies strategic partnership since July 2024 — processes 267,000 barrels per day, a significant throughput for a small Gulf state. Bapco Refining completed a major capacity expansion in late 2025, increasing jet fuel output by 90% and ultra-low sulphur diesel production by 72%.

Bahrain’s pipeline network also links into the wider Gulf grid. The A-B pipeline connecting Abqaiq in Saudi Arabia to Bahrain has been upgraded over its operational life — most recently with a new pipeline inaugurated jointly by King Hamad and Crown Prince Mohammed bin Salman — and remains the arterial supply route for both the refinery and the country’s gas distribution system. For context on regional pipeline infrastructure, the top 10 pipeline companies globally include several operators whose networks intersect with Gulf export flows from this corridor.

Bapco Upstream’s operating environment in 2026 is shaped by three pressures: maintaining production from mature reservoirs, developing the Pre-Unayzah gas play to reduce Bahrain’s import dependency, and contributing to Bapco Energies’ wider decarbonisation commitments. The contrast with larger Gulf operators — such as ADNOC, which has invested heavily in terminals and AI-driven operational infrastructure — reflects the different scale and mandate of a small-state NOC managing finite resources against long-term fiscal targets.
