Ultra-deepwater applications require high performance, modular well stimulation services.
The digital control system in Caltex’s Rigless Stimulation Tool (RST) helps in minimising flow path restrictions as its fast response time and seamless integration into a Multi-Purpose Service Vessel (MPSV) with multiple command stations ensure prompt addressal.
The tool can withstand any chemicals used in stimulations and scale treatments, ranging from acids, solvents, paraffin treatments, fines, and asphaltene deposits in production tubing, completions, and reservoirs. Operators can deploy RST to access candidate wells, particularly the ones with limited direct vertical access (DVA) under production facilities, to safely operate interventions as well as other activities.
Caltex’s RST is rated for sub-ambient pressure operations where the well mudline pressure is lower than hydrostatic conditions. The company's instrumentation and conduits are suitable from near 0 PSIA to 15,000 PSIA at 10,000 feet subsea.
