Independent Brazilian oil and gas firm OGX has concluded drilling operations at the Pipeline horizontal well 9-OGX-39HP-RJS, identifying very good reservoir conditions through a drill-stem test (DST). The Pipeline 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," said Paulo Mendonça, General Executive Officer and Exploration Officer for OGX. “We are continuing to move rapidly towards production.”
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.
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.
Following the conclusion of the drilling process, a DST was performed that indicated a production capacity of around 10,000 barrels of oil per day with an API gravity of approximately 19-degrees.
The Pipeline horizontal well uncovered new data which will help in the development of the 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.
