The company yesterday announced that its Kelln Trust-5-1 well was connected to a sales line and currently flowing at a daily rate of 84 barrels of condensate, 1 million cubic feet of gas and 15 bbls of water from the Atoka formation.
This flow is being achieved on a 30/64” choke with 335psi flowing casing pressure.
Last Friday, the company reported its Ellis-4 gas well had delivered strong flows from a recently perforated zone in the Morrow C zone. Following successful testing, the well was being tied back into the sales line. Antares’ equity in this well is 79.46%.
However in the same announcement, the company indicated that its acreage in this region has complex geology with faults compartmentalising the lease.
Kelln Trust-5-1, which was spudded by US-based operator Mewbourne Oil Company on November 25 last year, reached a total depth of 11,720 feet (3572m) on December 17.
The well was logged and cased, and perforated in the Morrow C zone at a later date. The Morrow C zone was then fracture stimulated with 100,000 pounds (45,360kg) of proppant.
Following clean up, Antares said the well was flowing water with little gas. The company said it believed the large stimulation fractured into the water-bearing sands below the Morrow.
After several attempts to flow from the Morrow C zone, the well was plugged back and the shallower Atoka formation was perforated. Following fracture stimulation, the well immediately flowed gas and condensate to surface while recovering frac fluids, Antares said.
Managing director Howard McLaughlin said Antares farmed-out equity in sections 5 and 8 to Mewbourne Oil to evaluate the western edge of its acreage at reduced cost and risk.
“This outstanding result from the Atoka helps validate the oil and gas potential of the overlying Atoka, Cleveland and Des Moines sands which have positive drilling and wireline log evidence of hydrocarbons in Antares’ other Ellis wells,” he said.
“After a period of production history from this zone, further tests may be warranted in the adjacent sections.”
Antares holds a 34% interest in the Kelln Trust-5-1 well.
