What are the applications?
EC-Drill® is used for drilling depleted zones, narrow pressure windows, unknown pressure regimes, extending casing strings, freeing stuck tools, managing loss zones, and supporting well testing.
Some applications for EC-Drill® include
- Drilling depleted zones
- Drilling narrow windows
- Running casing and cementing in depleted zones and narrow windows
- Running completions in depleted zones and narrow windows
- Drilling into unknown pressure regimes
- Extending shallow casing strings via the dual gradient effect
- Supporting Completions – particularly Open Hole Gravel Pack
- Freeing differentially stuck wireline tools, stuck completion assemblies or drillstring
- Drilling zones with risk of high or total losses
- Well Testing operations: reduce level to increase production flow temperatures
