Valeura Plans Turkish Well Frack
Canadian explorer Valeura Energy is starting the reservoir stimulation and testing operations on the Inanli-1 appraisal well in Thrace, west Turkey, it said June 25. Its only other partner is Norwegian Equinor.
Diagnostic fracture injection test and extended leakoff test operations are to start this week and the first reservoir stimulation is planned for next week.
Valeura intends to test a minimum of four zones in the Inanli-1 well, starting with the deepest. Given the rock's natural compaction with depth, the deepest zones are expected to have the lowest porosity and permeability. It also plans to test the Devepinar-1 well.
It expects to stimulate at least eight zones between Inanli-1 and Devepinar-1, and has designed the programme not to maximise flow rates, but to maximise data capture. The aim is to identify zones which provide the potential for future commercial flow with horizontal and/or vertical wells with massive development-type fracture stimulations, it said.
Valeura CEO Sean Guest said: "This is an exciting time for Valeura and our shareholders as we begin to develop a picture of the commercial potential for our basin-centred gas accumulation play by demonstrating both fluid characteristics and flow potential."
He said that the 11 vertical well penetrations into the over-pressured gas-bearing formations already drilled have given a strong understanding of the depth and breadth of the reservoir intervals. Valeura now wants to see how the rocks will flow with fracture stimulation.
