Drilling equipment leasing
In order to carry out jobs in special conditions (difficult drilling conditions, hard-to-reach regions of drilling) we offer positive displacement motors and turbodrills, containing bearing sections with multi-row axial sliding bearings, the operating surfaces made of synthetic diamond.
For these jobs we have the following operation life duration characteristics based on the experience of our equipment use:
|Equipment standard size (PDC bearing section)||Total time of equipment operation till writing off (till full wear of basic parts and assemblies)*, hr||Average overhaul life, hr||Guaranteed overhaul life**, hr|
* - Decision on writing off of the equipment is made individually for every item having received the results of nondestructive testing of basic parts and assemblies.
** - Guaranteed overhaul life is assigned individually depending on drilling conditions, condition of CJSC NGT specialist supervision at the field, condition of submission and quality of reporting allowing to track efficiently the equipment status etc.
Bypass valves, back-pressure valves and slotted strainers mounted in PDM leased have the similar data on average overhaul life and guaranteed overhaul life as the PDM of the corresponding size.
If required, we can offer engineer supervision services while well drilling, as well as services on transportation of the leased equipment to the field and back
