Includes the following services rendered on a fee or contract basis: advisory and consulting services relating to mining, on-land site preparation, on-land rig installation, drilling, drilling bits services, casing and tubular services, mud engineering and supply, solids control, fishing and downhole special operations, wellsite geology and drilling control, core taking, well testing, wireline services, supply and operation of completion fluids (brines) supply and installation of completion devices, cementing (pressure pumping), stimulation services (fracturing, acidising and pressure pumping), workover and well repair services and plugg ...[+++]ing and abandoning of wells.

The barriers of the underground storage site (e.g. the waste quality, engineered structures, back filling and sealing of shafts and drillings), the performance of the host rock, the surrounding strata and the overburden should be quantitatively assessed over the long-term and evaluated on the basis of site-specific data or sufficiently conservative assumptions.

The vessel also has three backup systems capable of activating the BOP and shutting in the well should the need arise to do so. It has an acoustic system; a remotely operated vehicle, ROV, intervention capability; and an automode function, AMF, which automatically activates the BOP and shuts in the well when the signal is lost.

Blowout preventers are installed before any critical pressure work is commenced on the well.
