It is increasingly difficult to find hydrocarbon reserves located in benign environments. This has resulted in the oil and gas industry moving to locations where significant drilling challenges are encountered. These challenges often lead to costly non-productive time with increased operational risk. In order to reach their objectives, operators have to make decisions “outside the box” to mitigate these challenges. Liner drilling technology has been introduced as a well construction technique in recent years proven to significantly reduce non-productive time with associated reduction of operational risks. As seen in the case histories presented, liner drilling in lieu of conventional drilling methods was identified as the only practical way, short of abandoning the well, for the operator to accomplish their objectives.
This presentation will portray five case histories in both shelf and deep water GOM where liner drilling technology was applied to mitigate lost circulation, wellbore stability issues and other drilling hazards. Also included is a discussion of the liner tool and casing bit systems implemented with brief well histories depicting the drilling hazard mitigated with the eventual outcome. Highlighted will be the operational parameters, liner drilling results with the associated value to the operator.
