Drilling at the Peró and Ingá prospects in block BM-C-40 and the Santa Helena prospect in BM-C-31 has turned up hits for Brazilian relative newcomer OGX. The operator has been focusing on shallow water opportunities (OE April) and has exploratory successes and one noncommercial well in the last month or so.
The company's Peró prospect encountered 35m of net pay in the Albian section of the 1-OGX-15-RJS well, which the Ocean Lexington drilled in 100m of water. Peró is 2km away from the Ingá well, which was still drilling ahead as this report was written.
The Ocean Ambassador was still drilling ahead at Santa Helena as this story was filed, but OGX had already reported finding pay in both the Albian and Aptian carbonate sections.
The 1-OGX-15-RJS well at the Santa Helena site in the Campos Basin in 130m of water intersected 31m of net pay in the Aptian section and 32m of net pay in the Albian section.
Paulo Mendonça, general executive officer of OGX, said the information obtained from the Santa Helena prospect reinforces the idea that the accumulation identified in the Albian section of the Santa Helena prospect is the same as that of the Etna (OGX-6) and Pipeline (OGX-2) prospects. Santa Helena is 1.8km northwest of the Etna prospect and 6.4km northeast of the Pipeline prospect. Earlier this year, OGX said the Etna prospect holds 17m of net pay in the Aptian section and 74m of net pay in the Albian section.
OGX holds 100% interest in both blocks.
The company struck out, however, with its 1-OGX-12-SPS – or Niterói – effort. The Ocean Star drilled the well in BM-S- 57 in the Santos Basin in 150m of water. While the company said the well was non-commercial, Mendonça said the well's objective was to test a new geological model. ‘The post-mortem of the well leads us to believe that the lack of a geological seal was the cause of a non-commercial hydrocarbon accumulation, given that the Albian structure is prominent. The fact that we encountered good reservoirs and confirmed the existence of an active petrolific system in this part of the basin is very positive since it decreases the risk in future wells,' he said. OGX holds 100% interest in the block.
OGX has tapped BW Offshore to complete the FPSO OSX-1 project and act as project manager for the owner. Under the $150 million contract, BW will provide the FPSO, which will operate in the Waimea field in 130m of water in BM-C-41 block in the Campos Basin. OE
