bp plc is preparing to appraise its Bumerangue discovery offshore Brazil, where it estimates about 8 billion bbl of liquids in place, with appraisal drilling expected to begin late this year or early 2027. As part of that plan, the operator has let an integrated drilling and evaluation services contract to Halliburton.
The appraisal is intended to provide dynamic reservoir data to complement the discovery's current static characterization, including information on how fluids flow through the reservoir, bp chief executive officer Meg O'Neill said during the company's second-quarter earnings call Aug. 4.
Halliburton's award covers an integrated package of drilling and evaluation services. The company, in a release Aug. 25, said its scope consolidates multiple drilling services under a single execution model and includes deployment of its LOGIX automation and remote-operations system.
The integrated approach will link well planning, drilling execution, and reservoir evaluation, Halliburton said, allowing drilling and evaluation data to be incorporated into operational decisions during the campaign.
Bumerangue discovery, plans
bp made the discovery in the Santos basin last year through the 1-BP-13-SPS well on Bumerangue block, 404 km from Rio de Janeiro in 2,372 m of water. The well was drilled to a TD of 5,855 m and intersected the reservoir about 500 m below the crest of the structure. It penetrated an estimated 500-m gross hydrocarbon column in high-quality pre-salt carbonate reservoir with an areal extent of more than 300 sq km.
Subsequent laboratory and pressure-gradient analysis confirmed an approximate 1,000-m gross hydrocarbon column, including a 100-m gross oil column and a 900-m gross liquids-rich gas-condensate column, bp said at the time.
Asked about the discovery on the Aug. 4 call, O’Neill outlined the potential for the company. “Having a fair amount of oil always gives you, kind of, one of the core ingredients we need to be successful in our business."
The appraisal campaign will move bp beyond the discovery's current static reservoir characterization by providing dynamic data on how fluids flow through the reservoir, she said.
And while O'Neill said bp is not expecting any major final investment decisions this year, she did identify Bumerangue among the company's upstream growth opportunities. bp previously noted plans to increase its global upstream production to 2.3-2.5 MMboe/d by 2030, with capacity to increase production through 2035.
