WORLD CLASS CAPABILITIES

HydraWell are the inventors of PWC® (perf, wash and cement) and owns several patents regarding this technology. The PWC® method replaces section milling for annulus remediation in several well abandonment applications including, but not limited to; P&A, Slot Recovery, Casing Shoe Repair, Annulus Pressure Remediation The method is run as a 1-trip system where a perf device (high shot density TCP guns) is run below the PWC® assembly to the planned plug depth. Guns are fired to create access to annulus for the washing operation to commence. Fresh wash fluid is jetted into the annulus before the subsequent cement job is done, leaving a uniform 360-deg cement plug in the area. This operation reduces the time to remediate a wellbore from 5-15 days with section milling down to 2 days with PWC®.

Some times the operator want to test the integrity of the annulus as part of a P&A or slot recovery programme. HydraWell have the solution called Annular Integrity Testing (AIT); A dual swab cup assy w/ TCP guns is RIH. At the depth where the formation is believed to be squeezing against the casing, the guns are fired–typically 100ft apart–and the AIT tool is positioned to straddle lower sets of perfs. Fluid is then pumped into the annulus, and if the formation is holding, no return is seen on surface. The tool can then be disconnected and a balanced cement plug set on top to finalise the barrier. Conventional methods consist of several runs to set bridge plugs and retriveable packers to perform testing. HydraWell´s AIT solution is a 1-trip system and can be done in less than one day.

Subsea Control Systems are a critical part of all operations linked to subsea wells. 4Subsea delivers subsea HPU control systems that can be used for all types of XT operations. The system reduces operational time and cost through reduced overall tooling need, simplified ROV scope and reduced topside logistics. The control system operates all types of XT systems from all main vendors and is therefore one common system for XT operations. It can be used for multiple fields and fluid types. In short, the system ensures reduced cost and time of well intervention.

Integrating advance immersive gaming technology and realistic 3D virtual environment, VE Gamified Simulator (G-SIM) enables training of complex and dangerous operations in a completely safe virtual environment without the expensive hardware of a traditional simulator.
