Quebec: Gaspe well has 1,850 m of hydrocarbon shows

Petrolia, Rimouski, Que., said it has installed tubing and will conduct a sustained production test of an open hole interval at 1,832-2,746 m in the Bourque-1 well in Quebec to see if it can obtain commercial oil flows.

Petrolia drilled the well to 3,140 m measured depth, 2,921 m true vertical depth, at a site halfway between Murdochville and Grande-Vallee on the northern side of the eastern Gaspe Peninsula. Wet gas shows containing condensate (C3 to C7+) in concentrations of up to 20% were registered over an 1,850-m interval between 995 and 2,852 m.

Each of eight drillstem tests of 20 to 30-m intervals yielded gas-condensate to surface. The most promising rate was 1.4 MMcfd. A small amount of light petroleum was also recovered in the drilling mud.

Starting at a depth of 1,465 m, in the cased section of the well, is a massive interval for which electric logs indicate porosity over a thickness of more than 100 m. This zone is characterized by abundant calcite from fractures and localized high-temperature dolomite. All drill cuttings from this zone displayed fluorescence when cut with a solvent, an indicator of oil in the rock.

In addition, a substantial show of gas was recorded at the top of the interval in a fractured zone, and 53° gravity oil was recovered in the sample chamber. This result led Petrolia to add oil as an objective for well Bourque No. 2.

Meanwhile, the company has moved the rig to the Bourque-2 site.
