Operator Reach Oil & Gas Company Inc expects to take eight days to drill Andrews 2-17 to a depth of circa 4,7000 ft, including perforating and flow-back if successful.
Union Jack said its partner estimated an 80% geological chance of success.
Andrews 2-17 is an up-dip offset well to Andrews 1-17, targeting the Hunton Limestone which is unconformably overlain by the main oil-prone source rock, the Woodford Shale
Union Jack added that 2-17 was expected to encounter a similar reservoir above the oil/water contact as the first well.
If successful, 2-17 will share common production facilities with 1-17 to cut expenditure.
Primary oil recovery is expected to be by solution gas drive with any gas recovered to surface being sold into the local network.
The company, with a 45% working interest, has paid drilling and completion costs of US$340,000 net.
Chief executive David Bramhill said that 2-17 could start producing within weeks from spudding.
“Similar low-cost development wells nearby demonstrate that rapid pay-back can be achieved within six months.
“The rate of progress from generating a drillable prospect, obtaining permission to drill and spudding in Oklahoma is remarkable.
“Work continues at the Andrews 1-17 wellsite, comprising installation of gas export facilities and further upgrades.
“This work is expected to be completed by late July/early August 2024, followed by flow rates and other associated information.”
The partners expect to expand their portfolio and establish an “impressive inventory of wells to be drilled”.
