Union Jack Oil announced this morning that the proppant squeeze planned for the Wressle oil well in North Lincolnshire had been approved.
Yesterday, the company said consent for the proppant squeeze was “awaited“.
But in a statement to investors today, Union Jack said
“all necessary consents have been received by the Operator, Egdon Resources U.K. Limited for the commencement of the proppant squeeze operation at the Wressle oil production site.”
A proppant squeeze involves the injection of fluid and proppant, such as sand, into the rock formation to improve the flow of hydrocarbons.
The Environment Agency regards it as a form of low-volume fracking because the injection pressure is high enough to fracture rocks.
The process needs a hydraulic fracturing plan (HFP), which outlines what an operator would do to minimise the risks of earth tremors from fracking. It also states how the hydraulic fracturing process would be monitored and controlled.
The HFP must be approved independently by both the Environment Agency (EA) and the Oil & Gas Authority.
Union Jack’s statement said today:
“The proppant squeeze operation is expected to optimise oil production from the Ashover Grit formation, one of the three productive reservoirs present, to a constrained rate of 500 barrels of oil per day gross (200 barrels per day net to Union Jack).”
Union Jack’s executive chairman, David Bramhill, said this morning:
“The proppant squeeze operation is the final phase of achieving our targeted oil production level and generating optimum cash-flows from the Ashover Grit reservoir.”
