OGX Petroleo e Gas Participacoes, a Brazilian oil and gas company, has identified an oil-bearing interval in the Albian section of well 3-OGX-21D-RJS, the first appraisal well targeting the Waimea accumulation previously discovered through the drilling of wildcat well OGX-3.
This appraisal well is located in the BM-C-41 block, in the shallow waters of the southern part of the Campos Basin, and OGX holds a 100% working interest in this block.
To date, an oil column of approximately 21m with about 14m of net pay was encountered in carbonate reservoirs in the Albian section, which correspond to those previously identified through OGX-3 well.
The well was still in the hydrocarbon zone when drilling was interrupted in order to conduct sampling, with the objective of running additional studies on the reservoirs.
Once sampling has been concluded, drilling will resume in order to determine the total column and net pay.
This well will be used as a pilot for a horizontal well, in which a cased hole drillstem test will be conducted.
The OGX-21D well, located in the BM-C-41 block, is situated 84km off the coast of the state of Rio de Janeiro, Brazil, at a water depth of approximately 134m.
