Bolivian Wells Provide Positive Test Results for Vintage Petroleum

Article excerpt

TULSA (JR) -- Vintage Petroleum has recorded positive results from three of its exploratory wells in Bolivia.

The Tulsa company has a 100 percent working interest in all three wells.

The company's first natural gas exploration well drilled in the Chaco concession, the Nupuco X-103, is a new field discovery made in the Carboniferous San Telmo formation. The well encountered 108 feet of net productive pay and has tested gas at a daily rate of 13.5 million cubic feet (MMcf) and 140 barrels of condensate. The producing zone had a calculated absolute open flow rate of 84 MMcf per day, indicating the high quality sand and deliverability characteristics of the well. Vintage said the well is shut-in, awaiting a pipeline connection scheduled early in the second quarter. In a bid to find new reserves below known producing horizons in the Naranjillos concession, near the city of Santa Cruz, the NJL X- 104 well was drilled and completed in the fourth quarter as a new field discovery in the Devonian Lower Iquiri formation. The well found 74 feet of net productive pay and was tested at a daily rate of 5 MMcf and 150 barrels of condensate. Additional zones of potential pay are behind pipe and will be completed as the company's allocation of capacity in the Bolivia-to-Brazil (B-T-B) pipeline grows. This well also is shut-in, pending the assignment of a production allowable into the newly constructed B-T-B pipeline. Drilling activity hs continued with another exploratory well, the NJL X-101, reaching total depth of 11,513 feet. …
