Straddle Test and Frac System
|
The WellStar Straddle Stimulation System is a fast, cost-effective way to remediate older wells by refracing underperforming zones. The system was designed to isolate and stimulate multiple stages in a single trip or restimulate existing perforated zones. With the zone isolated, the frac is pumped down the tubing. When the frac is away, a pull on the work string equalizes pressures and unsets the system. The Staddle assembly is then moved to the next zone to be stimulated.
• Stimulation of multi-zone wellbores – new/recompletes • Functions in vertical, deviated, or horizontal wells • Rapid deployment through live and fluid filled wellbores • Casing collar locator for depth correlation • Large tonnage fracs (>300 tonnes) • Over 400 wells successfully fracked • Maximum Depth: 5,500m (TVD) * • Average Tonnage: 280-320 tonnes • Average # of Zones: 20-25 |
Abrasive Milling and Cutting
|
Conventional Milling Technology was constrained by downhole restrictions. Increasing hardness of downhole objects will significantly lower the operational success rate. WellStar offers Abrasive Milling Technology, which wipes off downhole obstruction, as well as clients' overhead clouds. This technology has been proven successful in a number operations, which safes clients' time and money.
