Gulf Keystone, has commenced a drilling campaign to explore deeper, yet untested horizons of the world class discovery at the Shaikan field, which the company operates.
Shaikan-7, the first deep exploration well on the Shaikan block, is targeting the mid to lower Triassic and, potentially, Permian horizons, spudded late on Sunday 16 June 2013. The well is being drilled with the Weatherford Rig 319 (3000HP) close to the crest of the Shaikan structure, approximately 1 km east of the Shaikan-1 discovery well.
Shaikan-7 is being drilled to the lower Triassic to evaluate the potential for significant quantities of light oil and identify commerciality of the deeper Triassic reservoir. The well is then expected to penetrate the Permian, the deepest undrilled horizon to date on the Shaikan structure.
This vertical well is planned to reach a total depth below 4,500m in the Permian and the drilling is expected to take about 9 months.
"As we are about to commence implementation of our Field Development Plan for the Shaikan discovery and start Jurassic production from the newly constructed Shaikan production facility, the spudding of our first deep exploration well adds a new and exciting dimension to Gulf Keystone's work programme in 2013,” said John Gerstenlauer, chief operating officer.
“With Shaikan-7, we hope to confirm our expectations of major reservoirs beneath the deepest horizon drilled to date and add to what is already recognised as one of the world's largest onshore conventional oil & gas developments."
