Oilfield services company Halliburton introduced the Xtreme Single-Trip Multizone (XSTMZ) system for completing wells in deepwater and ultra-deepwater conditions up to 15,000-psi, to be used by a major operator in the Gulf of Mexico in 2020.
Based on Halliburton’s existing 10,000-psi rated Enhanced Single-Trip Multizone (ESTMZ) system, the increased pressure rating of the XSTMZ system allows operators to isolate and frac pack multiple zones at higher pump rates with larger proppant volumes. It also supports the ability to create zonal compartments for better stimulation of long pay zones that have high-pressure differentials between them, Halliburton said.
