Stress-strain curves of water-bearing sandstone samples. Fig. 6 shows sample strength alongside previously reported sandstones with water contents up to 7.95% [19], [21], [22], [23]. Sandstone strength decreases significantly with water content. Results from this study show a 18.75% decrease in sample strength from 60.72 MPa in the dry …MD-index is a measure of pore-scale displacement efficiency of the injected light hydrocarbon in a hydrocarbon-bearing zone. Theoretically, microscopic displacement efficiency can be calculated by dividing the displaced oil volume by the initial oil volume [28]. This necessitates calculations of the volume fractions of free oil, free water ...The use of water lubricated bearings helps to meet these evolving requirements. The viscosity of water (0.66 cSt at 40 °C) is much lower than turbine oils (32–68 cSt at 40 °C), so that water lubricated bearings can operate in a boundary/mixed lubrication regime for relatively longer time periods [3]. However, the lubrication …The development of water-bearing carbonate gas reservoirs is relatively complicated with water intrusion, which is the main reason for the increased difficulty and low recovery factor. The formulation of a rational development plan to prevent water intrusion has therefore been a long-term research focus.
