THE CHALLENGE
Operator BBC encountered sticking and had difficulty landing extended reach open hole completions due to hole conditions and high build rates of more than 12-15 degrees in the D J Basin, Colorado
THE SOLUTION
Operator ran 234 each (1 per joint) of 4 1/2” x 6 1/8” Centek S2 centralizers, floated between casing collars and ahead of swellable packers from top of liner hanger at 5,420ft MD to TD at 15,749ft. 9.5# mud wt. / 12.5# cement wt.
THE RESULT
The S2 reduced the torque and drag BBC had been realizing on previous completions. Completion string landed at TD in spite of a build rate that climbed above 15 degrees from approximately 5,700ft - 5,800ft MD.
