Staged Hydraulic Fracture Stimulation (Multiple Stage)
(Please allow time for video to load.)
Clay Exploration, Inc.
The subject sidetrack was drilled utilizing under-balanced drilling
practices and an initial completion attempted in November of 2002 utilizing Grey Wolf rig 702. When attempting to run
the production packer the packer was "stacked out" with excess compression resulting in a catastrophic failure
and subsequent fishing operations. Traditionally these wells must be immediately "cleaned up" post the
under-balanced drilling operations in order to evacuate cuttings and other drilling debris from the flow paths in the
well bore. This did not occur in a timely manner and the debris remains blocking the flow paths.
coiled tubing operations were conducted in an attempt to evacuate the wellbore of debris bridges. Due to curve severity
the mechanical integrity of the coiled tubing string was exceeded and the CT parted depositing a 201foot long 1.93"
OD obstruction in the barefoot production liner from approximately 15,560'+- to 15359'+-. (See schematic.) A failed
attempt was made to recover the barefoot production liner.
implement and establish productivity to the wellbore hydraulically utilizing staged acid assisted, high rate water
fracture stimulation thereby isolating "broken back" intervals with a fluid and temperature naturally
degrading LCM agent thus allowing stimulation to reach and open up the individual productive intervals at the extremity
of the lateral. (See "shows".)
