OREANDA-NEWS. August 12, 2011. OGX Petroleo e Gas, the Brazilian oil and gas company responsible for the largest private-sector exploratory campaign in Brazil, announced the conclusion of drilling at the horizontal well 9-OGX-39HP-RJS (“Pipeline Horizontal”) and as expected identified very good reservoir conditions through a drill-stem test (DST). The well is located in block BM-C-41 in the Campos Basin.

“This was the third horizontal well test that yielded important results, confirming the quality of the accumulations discovered thus far and that are being appraised. We are continuing to move rapidly towards production," said Paulo Mendonca, General Executive Officer and Exploration Officer for OGX.

The OGX-39 well was horizontally drilled for more than 1,000 meters into the carbonate reservoirs of the Albian section of the Pipeline accumulation, which was originally discovered by the 1-OGX-2A-RJS well in November 2009, and uncovered new material information regarding the development of this area. The results from the drilling of the OGX-39 well demonstrated a high correlation with other wells in the Albian section, including calcarenites with excellent porosity with dolomitized and naturally fractured sections, and confirmed the extension of the Pipeline accumulation.

Following the conclusion of the drilling process, a DST was performed which indicated a production capacity of around 10,000 barrels of oil per day with an API gravity of approximately 19°. The process of selective acidification was used in six well intervals, which enabled better stimulation of the 1,000 meter horizontal well extension, thereby maximizing the oil flow.
