What Is Reservoir Pressure?
Pressure on fluids in pores of coal reservoirs. It is often expressed in megapascals. Unless otherwise specified, coal reservoir pressure generally refers to the original reservoir pressure, that is, the reservoir pressure measured when the reservoir is in a pressure equilibrium state before it is mined (some say it is the pressure in the reservoir before it was disturbed by production ).

- Explanation: Coal reservoir pressure generally increases with increasing coal seam depth. The study of coal reservoir pressure is of great significance. It not only has an important effect on the gas content of the coal seam, the state of gas occurrence, but also the energy of gas and water flowing from the fracture to the wellbore. Coal reservoir pressure can generally be measured by well testing, and the commonly used method is water injection / pressure drop method. During the design time, a certain amount of water is injected into the test interval, then the well is closed, the pressure drops, and the bottom hole pressure is measured as a function of time. The reservoir pressure is obtained by extrapolation of the pressure curve. [1]
