Brochure Multistage Stimulation
Efficiency at every stage.
nZone multistage stimulation systems give you immediate capabilities for selective single-point multistage stimulation and future flexibility for reentry and rigless zonal shutoff later in the life of the well.
The two-position fullbore sleeves are designed for high-pressure and high-rate hydraulic fracturing operations. The inner sleeve is run in a pinned configuration and sheared when desired, providing positive indication that the specified port has opened before fracturing.
The sleeve can be opened, closed, and reopened, enabling operators to tailor production over the life of the well using the CT frac sleeve shifting tool. An adjustable detent locking system locks the sheared sleeve to prevent accidental manipulation and provides operators with reliable weight indicators to mark when the sleeve has shifted.
The shifting tool has been engineered as a fracture-in-place solution with no requirements for isolation or related service tools, even after hundreds of stages are fractured. The fully compartmentalized and hydraulically balanced design with multiple layers of solids control ensures that no solids will interfere with the tool’s operation.
KickStart rupture disc valve eliminates costly mechanical intervention to initiate perf-and-drop operation.
Complete up to 7 stages in horizontal, deviated, or vertical wells without intervention.
New production goals issued by the Chinese government of more than 6 million tons of oil equivalent per year in one field created a challenge to deploy new industry technology quicker.
Drilling activity has been steadily ramping up in China to meet the countries energy demand and government production goals. This is moving some activity to previously unexploited ‘tight’ formations requiring hydraulic fracturing to produce economically.
