Field trials of high temperature IRZ PCP downhole gauges in Tatarstan
IRZ high-temperature downhole gauges have been tested as part of PCP systems in steam injection wells in Alshanchinskoye field in Tatarstan. In total, 3 downhole gauge systems were tried in field. Each system is based on a quartz high-temperature gauge rated to 220 °C.
Inputs and Brief Case studies
Completed in September 2018
Cable length: 260 m to wellhead and 80 m along the surface
In March 2019 the well was converted to steam injection for two months at 182 °C. Then returned to production at about 100 °C
Current run life: over 11 months
Completed in December 2018
Cable length: 260 m to well head and 200 m along the surface
Right after run in hole the well was converted to steam injection at 184 °C. Injection was under way up to mid February 2019. Then, while trying to convert the well to production, the assembly jammed. The tools were pulled out of hole.
The downhole gauge is pending re-installation
Completed in February 2019
Cable length: 260 m to wellhead and 140 m along the surface
