First Interval of 197(1) Well Flow Test Results

Source: www.gulfoilandgas.com 8/25/2014, Location: South America

Alvopetro Energy Ltd is pleased to announce ongoing results from the first of three zones to be tested in our 197(1) well.

Our 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 our mud-logging and open-hole logs, we determined to initially test the productivity of three intervals discovered in our 197(1) well.

We perforated and completed the deepest sandstone interval, at 3,175 - 3,184 metres, which, based on our 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.

"The strong demand for natural gas and high energy prices in northeastern Brazil place us in an excellent position to commercialize our discovery," said Corey C. Ruttan, President and Chief Executive Officer. "The successful results, from the first of three zones to be tested in our 197(1) well, are a significant step forward in proving the commercial viability of our Gomo resource opportunity. We are optimistic about this gas opportunity, which potentially spans a large area, and we anticipate encountering this lower interval in our 183(1) well that is currently being drilled."

After completing the pressure build-up test, the zone will be temporarily suspended with a retrievable bridge plug and the completion will proceed up-hole to test the primary target, consisting of a continuous, thick, tight sand within the middle Gomo member, with a large mapped aerial extent.

The third interval to be tested is a more conventional sandstone interval with 20 metres of potential net pay with greater than 8% porosity. Based on open-hole logs, this zone has petrophysical characteristics similar to our Bom Lugar-1 producing well which had an initial unstimulated production rate of over 500 bopd and has cumulatively produced over 285,000 barrels of oil.

Alvopetro will continue the evaluation of the 197(1) well and we have procured surface production equipment to facilitate long-term production testing of any of the productive intervals in this well, pending customary approvals from the ANP.

On July 27, 2014, we commenced drilling our second well, 183(1), on Block 183. In addition to our 197(1) and 183(1) wells, we plan to drill up to three additional wells in 2014.
