Reducing Cost and Time on Remediation in Wyoming
An operator contacted ALTCem regarding holes in the production casing on an oil producing well in a water flooded field in Wyoming. The severity of the holes would not be known until an injection rate was established. ALTCem recommended a variable density slurry that could be adjusted on location. Once rigged up, the injection rate was identified as 2.5 bpm @ 900 psi. ALTCem recommended a thixotropic 13 lb/gal blend to ensure a good squeeze with adequate pump time.
The squeeze was successful, and held pressure once drilled out. The operator was very impressed as previous wells had required several squeezes before achieving a positive pressure test. By achieving the squeeze in the first attempt, the operator was able to save a significant amount of cost remediating the wellbore.
