It was decided
to run a test with Thuslick in 8-1/2" hole and in the 6" horizontal section of this well. The purpose of this test was to Replace Oil Mud With A Water Base Mud Using Thuslick. |
The 9-5/8"
casing was set at 8200 ft. This test was to help determine if the lubricant could help
with the torque and the sliding process in these section using a water base mud while
building the angle to horizontal an then drilling for approximately 2500 feet horizontally
for an open completion. At 8210 ft, 10 ft past the 9-5/8" casing shoe, torque was 325 amps with 50 RPMs. |
After drilling out the
shoe, the following readings were taken prior to adding Thuslick. |
|
Thuslick
was added initially at the amount of 4 ppb over one circulation. After one circulation
measured depth was 8922 ft. and the hole angle was 47 degrees.
