Isolate a low fracture-gradient zone to enable an optimal completion.
Install a Solid Expandable Tubular (SET®) system to isolate the trouble zones. Retain hole size across all the depleted sands in a narrow pore pressure/fracture gradient environment....
The operator was already utilizing SET® systems in a well slimming program that reduced upper hole sizes thereby improving ROP and significantly reducing overall costs. To further save time, the need for underreaming and cementing the expandable system was eliminated by incorporating a...
BP experienced losses while drilling a development well due to weak sand formation directly below the 13-3/8in. shoe. Multiple attempts were made to stem the losses - all without success.
A solution was required to isolate the weak sand formation and enable drilling to continue with higher...
Offshore Denmark, Directional Well, 8 5/8 x 10 3/4
The challenge was to set three multilateral windows at an optimum Total Vertical Depth (TVD) in the reservior.
In the Utica Shale, an Operator drilled three wells and experienced loss zones and formation integrity issues.
While drilling an exploration well, an Operator encountered a narrow pore pressure/fracture gradient window that required using more casing strings than planned.
Isolate a lower pressured oil production zone from other nearby higher pressured zones to mitigate cross-flow between the different reservoirs.
SET® solid expandable technology enabled the Operator to stay on course with the planned reservoir drilling and completion solution, due to the preservation of hole size.
