(geology)
The pressure on fluids (water, oil, gas) in a subsurface formation. Also known as formation pressure.
The pressure under which fluids are confined in rocks.

These sand control measures are designed to improve the production rate and to minimize reservoir pressure drawdown, resulting in better performance and longevity.
Use of a small reservoir with a higher maximum reservoir pressure to ensure cylinder filling at high speed would waste energy and risk an excessive overall compression ratio if the engine was suddenly decelerated.
This was achieved by using a stand-alone gathering facility to process produced fluids and re-injecting up to 240,000 barrels of produced water back into the aquifer to maintain reservoir pressure, while additional infill producer wells increased the yield from the field.

The complications caused by high reservoir pressure are that drillers must be extremely careful when drilling into the pressurized formation so that a gas "blowout," or an uncontrolled flow of gas, does not happen.
USPRwire, Tue May 07 2013] Artificial lift is used to provide adequate pressure in a low reservoir pressure well to thrust the crude to the surface.
Completed in 2003, this keeps reservoir pressure at the fields stable and has boosted gas production and exports as well as enabled the fields' recoverable reserves to last for another 31-33 years.
The compressors reinject this gas for reservoir pressure maintenance, effectively storing the gas for future production.
The systems will be used for two new pre-compression units to improve production capacity and extend the lifespan of the field, where gas extraction has led to reduced reservoir pressure and declining production.
Production from these wells has over time declined naturally with gradual depletion of reservoir pressure and in some cases sand being carried into the wells' tubing, these wells and are now producing
It plans to build water collection, treatment and injection facilities to pump as much as one million barrels per day (bpd) of water into the Wara geological formation to maintain reservoir pressure and production levels at the field.
Additionally, static reservoir pressure readings indicated that the main Ordovician gas reservoir in this area is in the same pressure regime as that encountered at wells AT-1, AT-2, and AT-3.
