Sakhalin extended-reach well pushes ERD envelope to a world record
Michael W. Walker
To reach reserves in the Odoptu field, located offshore Sakhalin Island, Russia, ExxonMobil, as operator of the Sakhalin 1 project, drilled nine extended-reach wells from the Sakhalin Island shore, culminating with the record-setting OP-11 well. Lessons learned on these wells will be useful for designing future extreme ERD wells.
ShaleTech: Haynesville operators look to exports for relief
Despite being home to some of the most prolific gas wells in the U.S., the once-celebrated Haynesville-Bossier shale has been relegated to little more than an afterthought, as cellar-dwelling commodity prices and comparatively excessive drilling and completion costs force even the most resolute operators to shut in and await better times.
