Petrolia Confirms Hydrocarbons at Bourque Well

change text size

Pétrolia confirmed that results of analysis on well Bourque 1, drilled in summer 2012, reveal the presence of a reservoir containing important quantities of hydrocarbons, some of which is oil. This result justifies the mandate given by Petrolia to an independent expert, Sproule Associates, to evaluate the hydrocarbon volume initially in place in this reservoir. Located in the Forillon Formation, it is characterized by the presence of numerous vugs which can reach large sizes, up to several tenths of centimeters and which are associated with open fracture zones.

The analysis of an imaging log (FMI) by Schlumberger Canada confirms the presence of a reservoir of good capacity. The analysis demonstrates that the Bourque 1 well penetrated numerous zones where this type of (vuggy) porosity develops, between the depths of 1465 m and 1820 m (355 meters interval).

This result adds to those obtained during drilling, when two tests carried out on part of this interval have demonstrated the presence of hydrocarbons, including oil. One of these tests (at the top of the interval) recovered very light oil (53 degree API) whereas the second one (in the center of the interval) yielded an initial flow of 1.4 million cubic feet per day of wet gas.

Vuggy porosity cannot be detected during analysis of the drill cuttings (one to two millimeters in diameter) because of the large size of the vugs (up to several tenths of centimeters). In carbonates, this porosity is often associated with weathered zones located close to main faults, such as the North-West Arm fault which transects the Bourque structure.

The regional context suggests that weathered zones containing this type of reservoir could be present along the North-West Arm fault, which extends over more than 37 miles (60 kilometers) length. Acreage located along this fault thus becomes an interesting target in the search for hydrocarbons.

Considering these results, Petrolia has chosen to develop a production test program in order to properly evaluate the porous interval discovered in the Bourque 1 well. Production tests are also planned in the deeper section of the Bourque 1 well, as well as in the Bourque 2 well.
