On August 1, 2010 Essential completed the re-branding of its service rig operations. All service rigs now operate under the name of Essential Well Service.
Essential’s service rigs provide production/workover and well completion services. Service rigs are used to repair, re-complete and stimulate existing oil and natural gas wells and perform completion work on new wells. Service rigs are typically operated by a crew of four or five workers. The rigs include a pump and tank as well as blow out preventers and support equipment.
Essential’s fleet of 59 service rigs includes:
- Single Mobile Service Rigs: 37 (all free standing)
- Double Mobile Service Rigs: 21 (9 free standing)
The service rigs operate throughout Alberta and into B.C. and Saskatchewan from the following field locations:
Fort St. John
All of Essential’s service rigs are crewed with experienced staff. They are operated in a safe, cost effective and environmentally responsible manner and maintain COR certifications and are members of the CAODC.
Essential's rig packages include a doghouse, pump trucks with a tank, BOP’s and equipment trucks. Supplementary equipment such as pipe racks, boilers, light plants, matting, and accumulators for class III BOP operation are available.
Eight of the service rigs are newly constructed in the last four years. All of Essential’s service rigs completed their Level 4 inspections and retrofits since 2000 with over 50% of the rigs having Level 4 inspections since January 2006. Level 4 retrofits are required for every 24,000 hours of operation. The rig and support equipment are stripped down, the rig components are dismantled, sand blasted and inspected. In most cases the major components - engines, transmissions, drawworks, pumps, derricks and overhead equipment are refurbished or replaced. When preparing for the Level 4 retrofit, the rig is upgraded with a new carrier, state of the art fall arrest and derrick egress systems and are converted to free standing, if required.
