Rig Chase
Use the drilling rig to what it was built for
- drilling holes and finding precious hydrocarbons.
The Rig Chase™ Program enables the drilling rig to leave well site after retrieving the BOP, reducing time on location and increasing the rig move weather window.
Our Rig Chase Program™ increases the return of capital invested (ROCI) by each well. Removing a non-value adding part of the drilling schedule to a low cost vessel improves utilization of a rig slot.
