Oilex (ASX:OEX, LON:OEX) told investors that 76% of the fracking water has now been recovered from the Cambay 77-H well, and the clean-up phase is continuing.

In the most recent measure, taken in the early hours of Monday October 6, the well was flowing at a daily rate of 229 barrels of water and oil, and 410,000 cubic feet of gas.

“Oilex is pleased with the well's performance at a relatively small choke,” said managing director Ron Miller.

“Flow back is all about removing the water put into the reservoir during frack and coil tubing operations, as this impairs the hydrocarbon production rates. We look forward to the improved water recovery leading to better oil and gas production."

The company also told investors of a set-back in operations to replace the ‘frack tree’ installed at surface with a standard production tree. The problems led to a piece of equipment becoming stuck in the well, though recovery operations were completed over about 13 days.

Replacing the tree was intended to boost flow back from the well and subsequent to the operations Oilex said the well has exhibited a significantly improved performance.

Oilex said efforts are underway to optimise operational parameters to enhance the recovery of water, including the cessation of nitrogen lift activities, which will help bring forward the production testing phase – which comes once clean-up is complete.

In the meantime the company continues to sell the oil that’s produced during the clean-up, and it is working so that it can sell the gas too.
