reservoir pressure

[′rez·əv‚wär ‚presh·ər]
(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.

In the same overburden stress and reservoir pressure, the rock framework and pore are compressed continuously as time goes on, which means that the stress sensitivity is related to time.
The effective stress increases while the reservoir pressure depletes, in which, in turn, the porosity and permeability of shale reservoir change due to rock matrix deformation.
This zone is characterized by excessive reservoir pressure. The considered mechanism of formation and reformation of gas condensate fields up to large sizes due to excessive pressure in the elevated structure parts of the SCD provides a more reasonable explanation of their vertical and horizontal zonation.
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.
Retaining reservoir pressure when stopped would be near impossible with all the potential leakage paths.
Sonatrach has been re-injecting 62 BCM/y of gas to keep reservoir pressure. The field's gas is wet, having 200 grammes of condensate and four grammes of LPG per cubic metre which has required a partial recycling for the gaseous gas to be recovered.
Two gas turbine-driven pump trains will also be installed to provide treated seawater injection for reservoir pressure support and a new 165MW cogeneration power plant built, with around 45% of the power generated by recovering waste heat.
It boasts the latest touch screen technology, digital monitors and gauges to measure reservoir pressure, volumes and flow rates.
They will help maintain gas pressure at gas fields with reservoir pressure depletion.
These issues are divided into two types: Initially, the behaviorof the well in designing a completion for a new well during a short term where we need to assess the effectof the form of completion, and initial production condition on well productivity.The second issue is related to the long-term behavior of the well where the productivity changesare considered and predicted as the reservoir pressure declines.This study uses the reservoir model for this meansand carries out sensitivityanalysis to evaluate its impact for current and future wellbore optimization and improve well performanceby lowering wellhead pressure and similarly to find optimum time to change the tubing size andthus make it possible to observe the longevity of the well.
At Prudhoe Bay, for example, the reservoir pressure at the start of its production was about half of the pressure at Point Thomson.
