Our well integrity program is a mechanism to ensure the sound quality and healthiness of all its completion components with the ultimate aims of safeguarding the life, environment and shareholder investment. Our Well Integrity Manual contained all the best practices and standard across the E&P.
Our unique standard surveillance mechanism and corrective methodologies for all well types (oil, water and gas) will help put our client in best class position on well integrity. The developed program not only ensures the identification of well problems at its infancy but also maintains the healthiness and upkeep of Clients assets. This Integrity plans focused on the following three (3) primary well integrity methods:
Surface Well Integrity Testing (WIT) – The WIT comprises the flow-wetted parts of the completion. An improved first-line maintenance.
- Sub-Surface Integrity Testing (SIT) – The SIT comprises all the sub-surface fluid containment conferment of all flow-wetted parts of the completion. WIT and SIT are intended to be intervention less. However it has been recognized that, in order to acquire true knowledge of whether or not a valve can be considered a barrier, there may be a need to set plugs in the completion or the wellhead and pressure test against these to establish their integrity. Such a test would be called a Pressure Integrity Test, PIT.
- General Routine and Corrective Maintenance – secondline maintenance
Our services include routine Wellhead Maintenance as well as Wellhead Completions. Our expertise covers various Wellheads, Chokes & Valves including Cameron, Vecto Gray, FMC & Kvaerner. Comprehensive valve refurbishment are carried out by skilled engineers and technicians at our dedicated workshops in Benin and Warri.
GetOil supplies quality Wellhead systems to suit all casing size requirements – to full API specifications. We provide conventional gaslift valves, mandrels, deployment tools and all mechanical and fluid system needed for well securing.

New back pressure valve lubricator and VR plug side door lubricator to support increasing wellhead demand within Nigeria market. Just concluded 50 strings WIT and secondline and just commencing 30 strings well second of non-integral wells using NRV, VR plugs and brine fluid where no top packer or high casing communication. |

| Warehouse with new and newly repair manual and auto flow valves for client and those warehoused for future usage during secondline or adhoc repairs and sales. The warehouse house contain over 30 of both manual and auto manual and SCSSV actuators for various wellheads. |  |
|
Set of various sizes of NRV plugs for well securing and usage during temporary wellhead intervention. Over 30 were installed this year successfully in our client wells.
