Graph: OMV Completes Two HPHT, Extended-Reach Exploratory Wells Using Integrated CT System in 14 Days - Vantage logging head system, ASFS firing system, and e-line coiled tubing overcome challenges, save operator USD 760,000 in additional runs
After running several simulations, Schlumberger recommended the Vantage system modified for high temperature (400 degF [204 degC])  by incorporating high-temperature seals throughout the tool. Using the Vantage system, ASFS system, and e-line coiled tubing, OMV was able to set plugs, pressure test the plugs, and perforate two different depths in the same run. OMV successfully executed 10 plug-and-perf runs in just 14 days without any NPT in the first well, saving USD 760,000 in additional runs in the second well.

Background
OMV needed to conduct rigless multistage hydraulic fracturing for a total of 11 zones in two horizontal wells. However, high bottomhole static temperatures and extended laterals posed major challenges for plug-and-perf operations; the high temperatures limited the use of tractors, which were rated to only 350 degF [177 degC].
