OGX successful with Waimea appraisal well offshore Brazil

Source: OGX

Independent Brazilian firm OGX has identified an oil-bearing interval in the Albian section of well 3-OGX-21D-RJS, the first appraisal well targeting the Waimea oil accumulation previously discovered through the drilling of wildcat well OGX-3. 

The Waimea oil field appraisal well is located in the BM-C-41 block, in the shallow waters of the southern part of the Campos Basin. OGX holds a 100% working interest in this block. 

To date, an oil column of approximately 21 meters with about 14 meters of net pay was encountered in carbonate reservoirs in the Albian section, which correspond to those previously identified through well OGX-3. 

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 84 kilometers off the coast of the state of Rio de Janeiro at a water depth of approximately 134 meters. The rig Sea Explorer initiated drilling activities there on September 28, 2010.
