Alvopetro's 197(1) well reaches a total depth of 3,275 metres

Alvopetro Energy Ltd. says that the 197(1) well reached a total depth of 3,275 metres, and we encountered 43 metres of potential net hydrocarbon pay over several separate intervals, with an average porosity of 9.5 percent, using an 8 percent porosity cut-off. Given the geological potential displayed on mud-logging and open-hole logs, we determined to initially test the productivity of three intervals discovered in the 197(1) well.

We perforated and completed the deepest sandstone interval, at 3,175 - 3,184 metres, which, based on the petrophysical analysis, is representative of four analogous uphole intervals in the same zone. Over a 67 hour test the 197(1) well flowed natural gas, on an unstimulated basis, at an average rate of 40 mcf/day, with no water, on an 8/64" choke, using 2 7/8" tubing, from the Gomo Member of the Candeias Formation. Cumulatively, the well produced 112 mcf of natural gas for the duration of the test. The initial wellhead pressure at commencement of the 67 hour test was 159 psi(g) and increased to 213 psi(g) at the end of the test. The well will be shut-in to measure reservoir pressure and obtain pressure build-up data to undertake a pressure transient analysis. This will allow us to predict what this zone could produce on a stimulated basis.
