Gas2Grid reports problems at Philippine onshore test well

Gas2Grid announced recovery levels close to 100 per cent prior to the interruption

Small amounts of fine grained clay from the reservoir sandstone plugged the perforations through which the produced oil is fed into the wellbore during swabbing operations at the well.

This result has confirmed that the Malolos-1 sandstones being tested are oil reservoirs.

Current operations at the well are focused on clearing the plugged perforations. Once the perforations are cleared oil testing will resume.

Swabbing fluid from the production tubing and lowering the fluid level reduces the back-pressure on the oil bearing formations, which Gas2Grid has said resulted in the percentage of oil being recovered increasing to almost 100 per cent.

The extended oil production testing program aims to gather sufficient technical information to confirm commerciality of the Malolos oilfield.

On the 29th January, 2014 Gas2Grid reported a “Contingent Resource” of oil in the two productive sandstones for the Malolos oilfield between a “Low Estimate” (1C) of 6.8 million barrels and a “High Estimate” (3C) of 68.1 million barrels.
