Having set and cemented the surface casing at around 1,100 feet, and installed and tested the well head and BOP stack, the Jewell Well was drilled in the vertical section to a depth of around 6,850 feet.
During the last 36-hours the drill string was tripped out of the hole and the well was prepared to receive intermediate casing and at around 9pm CDT on Sunday 16 May 2021, operations to set and cement the intermediate casing were successfully completed.
The Jewell Well is the first well in a potential 5-year, 20-plus well development drilling program across the three operated DSU’s (Jewell, Flames, Rangers) that the company controls in the SWISH AOI to develop a conservatively estimated 11,606,000 net barrels of oil equivalent prospective resource (best estimate, unrisked).
Targeting the Sycamore Formation
The Jewell Well will be targeting one of two primary producing formations in the SWISH AOI, the Sycamore formation, which continues to deliver outstanding sustained productivity in nearby offsetting wells.
To date, the Casillas Operating, LLC. operated Flash 1-8-5MXH well (around 3-miles west of the Jewell DSU) has produced about 580,000 barrels of oil equivalent in around 19-months, considerably higher than Brookside’s conservative estimate for the Jewell Well.
The Woodford formation
Future wells in the Jewell DSU will also target the Woodford formation, which just like the Sycamore formation continues to deliver outstanding sustained productivity in nearby offsetting wells.
To date, the Continental Resources Inc. operated Courbet 1-27-22XHW well (about 1-mile southwest of the Jewell DSU) has produced around 430,000 barrels of oil equivalent in around 14-months.
The production rate of the Courbet well is also considerably higher than BRK’s conservative estimate for the Jewell Well.

The well is being drilled as a mid-length horizontal well targeting the Sycamore Formation at a depth of around 7,800 feet.
It will be drilled to a total measured depth of around 14,700 feet, with about 7,100 feet of lateral section drilled in the Sycamore that will subsequently be cased with production tubing to be perforated and treated to allow production of oil and gas.
Looking forwards, the company plans to trip back into the hole with full bottom hole assembly to drill ahead and build and land the well bore curve in the target formation.
Post drilling of the curve, a 73/4 inch liner will be set prior to commencement of operations to drill the lateral (horizontal) section of the well.
