... and circulating pressures targets to avoid increasing the risk of dynamic induced loss of circulation. The premium lubricant reduced the friction factor by 0.01. The cost of this technology is negligible compared to the risk associated with failure to deploy frac string. This was a new concept put to test which...

Additionally multiple pressure-testing cycles are required post cement-setting and during the completion phase, a practice that can destabilize the cement system causing it to fail. Moreover, controlling loss circulation while...

... Abstract The deep carbonate reservoir formation on this field has proven to be an extreme High-temperature (HT) environment for downhole equipment. While drilling the 5000 - 6500 ft 5-7/8" slim long laterals across this formation, very high bottom-hole circulating temperatures is encountered...

For the sampling operation, a maximum allowable downhole gas volume is evaluated prior to operation and simulations are compared to surface gas observation obtained during a wiper trip (mud circulation). During DTT operations, pumped...
