COBRAMAX® DM CASE STUDY
CobraMax® DM service unlocks reservoir potential and reduces risks
An operator in the Marcellus shale was looking for an innovative method to fracture 30 intervals with maximum near-wellbore conductivity and diversion but with lower risks than conventional perf-and-plug methods
Solution
Halliburton proposed its CobraMax® DM service to deliver maximum reservoir performance but optimal control to pilot proppant concentration for diversion and near-wellbore conductivity
With CobraMax® DM, all the proppant is pumped in the coiled tubing while clean fracturing gel is pumped in the annulus tubing x coiled tubing
Result
Time between treatment stages was reduced to about 40 minutes - operations were conducted in a continuous process
Indications of an early screen-out were mitigated by proppant slurry overflush, allowing treatment to continue
An early screen-out occurred and was mitigated, with a total impact on process efficiency of less than 6 hours
Horsepower requirements were reduced to 15,000 Hhp as compared to 30,000 Hhp
