Applications
ENHANCED OIL RECOVERY AND RESSURE MAINTENANCE
Nitrogen is used to maintain the reservoir pressure of formations that have suffered diminished productivity over time from natural pressure depletion. The oil production of wells with limited gas reserves can be enhanced with reservoir pressure supplied by N2 injections.
NITROGEN FLOODS
Since nitrogen is essentially immiscible with oil and water, an N2 injection program, or flood can drive unrecovered hydrocarbons from an injector well to a producing well for subsequent production.
GAS LIFTING
The production of wells experiencing pressure depletion can be enhanced if the hydrostatic head can be lightened by introducing N2 as a gas lift mechanism in the annulus of the well or in parasitic strings. The hydrostatic pressure is reduced, promoting greater oil and gas production
OIL AND GAS TRANSPORTATION
MEDRA ARABIA offers economic and logistical advantages over the traditional Nitrogen suppliers for pigging and purging of pipelines. The same units can be used for nitrogen inerting and blanketing of ship/barge or truck mounted storage facilities.
BOP CLOSURE DEVICE/HEAVE COMPENSATORS
The BOP closure response time can be greatly enhanced when incorporating nitrogen charged accumulator system. Nitrogen not only provides a stable pressure for the BOP and heave compensators systems, it also provides internal corrosion
INSTRUMENT PANELS
Nitrogen provides a dry inert corrosion free atmosphere for the instrument panels prolonging the life of the systems and preventing many costly shut-downs.
INERTING TUBULARS
When transporting drilling/production tubing or coiled tubing from the rig/platform to the shore base, it may be necessary to inert the tubing before shipment. MEDRA ARABIA can provide an on-site gas separation system to meet that requirement.
WELL COMPLETION OPERATIONS
For well completion operations, nitrogen is used in cementing operations. pressure-testing equipment, setting packers and other pressure-activated devices, as well as controlling cement slurry weights. N2 can be used in detonating charges for perforations. The low density, high pressure N2 is also ideal for well cleaning and fluid displacements.
WELL WORKOVER OPERATIONS
New or existing wells that suffer from poor production rates can often be revitalized by fracturing the formation to increase effective formation volume or introducing stimulation fluids and acids to improve oil permeability. High pressure N2 can displace drilling fluids, reduce hydrostatic heads, and allow the well to commence production.
