... Sato and Horne (2018) used loading efficiency, computed from permanent downhole gauge data, to estimate the in situ pore compressibility and the near-wellbore CO2 saturation in a CCS pilot application. Their analaysis showed that, after the injector well was shut-in, the loading efficiency...

... intervals experiencing a reduction of reservoir pressure of more than 2,000 psi. Moreover, reservoir compaction and pore collapse become more serious with the increasing stress acting on the rock framework—particularly upon reaching a critical pressure value. Laboratory measurements of rock compressibility...

... At least three testing types are required to calibrate the simplest version of the cap model: a hydrostatic compression test, triaxial tests and uniaxial pore volume compressibility (UPVC) tests. Hydrostatic compression test is performed by pressurizing the sample equally in all the directions...

... go throughout three tasks. The first is developing the pressure functions of reservoir mobility and total compressibility by developing several correlations for reservoir fluid properties such as oil, gas, and water formation volume factor as well as gas solubility in oil and water. Several...

... Abstract The Middle to Late Cretaceous Natih formation in Oman can be highly compressible and undergo large compaction during depletion. Significant reservoir compaction and surface subsidence has potential risks for fault reactivation, integrity of wells and surface facilities. Petroleum...

... Abstract Offshore reservoirs are subjected to pressure loading from the ocean tide. The resulting pressure fluctuation, notably its amplitude and phase, provides valuable information about the formation compressibility and heterogeneity. The purpose of the present study is twofold: first...

... was varied in 11 experiments from atmospheric to 500 psi with a net-confining pressure of 1,000 psi. A compressible fluid (brine with air) was injected through the core at a constant rate while a backpressure regulator maintained pore pressure in the flow studies. Fluid compressibility was also calculated...
