Single-treatment scale prevention sustains production: Utah
Owing to the persistent build-up of carbonate and sulfate scales in its Greater Monument Butte Unit (GMBU) wells in Utah’s Uinta Basin, the operator relied on liquid phosphonates and particulate-based inhibitors to prevent production restricting deposits, which nonetheless continue to re-emerge.
Within the GMBU, excessive volumes of produced water are intensified by a long history of waterflooding, causing scale to form quickly and frequently, effectively seizing rod pumps and downhole tubulars in a matter of days. Compounding the reduced production, persistent scale build-up can reach the point where a squeeze is the only option, requiring rod and other downhole hardware be pulled, which can conservatively cost up to $25,000 per treatment. Thus, the operator sought an alternative and longer-lasting solution that would sustain oil production for multiple years without the frequent remediation.
