... Abstract Archie parameters, porosity exponent m and saturation exponent n , are required inputs for formation evaluation. Depending on rock types, both m and n are routinely obtained from core analyses, which require reservoir cores and fluids. Such determined m and n values are discrete...

... the fracture pressures with an excellent precision where the coefficient of determination (R 2 ) is greater than 0.99. In addition, the artificial neural network (ANN) was compared with other fracture pressure models such as Matthews and Kelly model, which is one of the most used models in the prediction...

... within the crushed zone region revealed significant compaction, with porosity reductions ranging from 10 to 50% below that of the native rock. Permeability at one of these selected locations was determined and found to be reduced by approximately 35% below the native rock value. The second experiment...

...°C, accurately measuring the point becomes difficult. Determination of the thermal maturity of overmature samples is problematic, especially in samples which contain no vitrinite, but with measurement of the Tco (°C), new thermal maturity measurements may be possible. It should be noted...

This study investigates the impact of pressure-depletion induced asphaltene precipitation on interfacial tension (IFT) and contact angle for live-oil systems at reservoir conditions (high-pressure high- temperature); and presents a graphical (quantitative) method for determining...

.... An accurate invasion correction chart has been constructed to determine values of d i , R xo /R t , and R t . Without this correction a serious error could result in the calculation of water saturation (S w ), especially in a deeply invaded formation and with R xo >> R t . log analysis Upstream...
