... wells. Hydraulic snubbing units could not be used in many of the wells because they were completed with cement-lined tubing. Additionally, these units were inherently cumbersome and hazardous to the crew. Kill-weight fluids provided an alternative to the previously mentioned methods. These fluids can...

... should the primary function of the well control stack fail. To be consistent with industry-established well control practices, coiled tubing operations must provide a means for regaining well control through the pumping of kill-weight fluids to create the desired hydrostatic pressure balance within...

... or uncontrolled wells. Snubbing units were mounted on the drilling rig floor, and tubulars were moved through ram blowout preventers (BOPs). Snubbing is now more frequently used to avoid damage to sensitive formations caused by water or kill weight fluids, but snubbing can be used for other situations where...

Introduction With the increased use of underbalanced drilling and completion techniques using coiled tubing and snubbing, wells can now be brought on production without subjecting the formation to kill weight fluids. In addition to cost savings benefits related...

... Abstract A leading exploration and production company in India needed to conduct high-pressure/high-temperature (HP/HT) testing on a deepwater well. Deployment of the drillstem test (DST) tools in a kill-weight mud system as a testing fluid could have resulted in challenges with tool operation...
