lvopetro Energy Ltd. (TSXV:ALV) announced results from their 183(1) well test, located on block 183 in the Recôncavo basin in the State of Bahia, Brazil.
As quoted in the press release:
We originally drilled the 183(1) well in 2014 to a total depth of 3,550 metres and, based on open-hole logs, encountered 168 metres of potential net hydrocarbon pay over several separate intervals, using a 6% porosity cut-off. We initially planned to test two intervals and potentially a third contingent interval.
We perforated and completed 10 metres of potential net pay in the first interval in the Gomo Member of the Candeias Formation, with 9.7% average porosity. Over the 6-hour, cased-hole test the interval flowed natural gas, on an unstimulated basis, at an average rate of 6,800 m3/d (240 Mcfpd or 40 boepd), through a 12/64″ choke, with a final flowing tubing head pressure of 1,720kPa (249 PSI). During the test period, in addition to the natural gas, we recovered 11 barrels of load fluid. After shutting in the well, an injectivity test was performed to evaluate permeability and expected post-stimulation productivity. The interval has been temporarily suspended with a bridge plug.
In the second interval, we perforated and completed 6 metres of potential net pay in the Caruaçu Member of the Maracangalha Formation, with 11.1% average porosity. Over the 34-hour, cased-hole test the interval flowed natural gas, on an unstimulated basis, at final stable rate of 2,600 m3/d (92 Mcfpd or 15 boepd), using 8/64″ choke, and the flowing tubing head pressure was 2850kPa (414 PSI). During the test period, in addition to the natural gas, we recovered 12 barrels of 61° API condensate.
The second interval was suspended temporarily with a bridge plug and the test proceeded up-hole to test a third interval where we perforated a 15-metre, 11.5% porosity interval, in the Caruaçu Member of the Maracangalha Formation. This test produced formation water and no material quantities of hydrocarbons.
Alvopetro is currently analyzing fluid composition data from the second interval and pressure data from both the first and second intervals. These analyses will allow Alvopetro to predict productivity of these two intervals on a stimulated basis.
