When a major North Sea operator evaluated the potential of using through tubing rotary drilling (TTRD) to sidetrack a 20-year-old well in a UKCS field, it identified significant cost savings... more

Complete many zones in one trip

Depending on well depth, tripping time can account for a significant amount of non-productive time (NPT) and make a major impact on overall completion cost. Minimizing NPT is critical to... more

Combine sand control and liner drilling

Drill-in solid liners have proven valuable for reaching target depths beyond trouble zones. When depleted zones, lost circulation zones or unstable formations are encountered, drilling Figure 1. Baker Oil Tools’... more

Coupled geomechanics predicts well failures
