Knowledge of Previous HitreservoirNext Hit fluid properties is essential during the development phase in order to implement an optimal Previous HitreservoirNext Hit management strategy for properly exploiting the reservoirs. Interfacial tensions of Previous HitreservoirNext Hit fluids, as well as contact angle, are important parameters for many Previous HitreservoirNext Hit engineering studies. Examples are imbibition studies and calculation of fluid saturation in the gas-oil transition zone. Both interfacial tension (IFT) and contact angle of the fluids/rock Previous HitsystemNext Hit affect the distribution of fluids within Previous HitreservoirNext Hit rock material. The fluids distribution strongly affects the flow behavior and hydrocarbon recovery. Most of the available contact angle and IFT data for gas/brine systems are for room temperature and atmospheric pressure. Since actual values of Previous HitreservoirNext Hit temperature and pressure are frequently used in Previous HitreservoirNext Hit simulation models, a need to study IFT and contact angle at Previous HitreservoirNext Hit conditions was recognized. This study is an investigation of the influence of temperature and pressure on IFT and contact angle of Khuff gas and condensate fluids. Experimental results of IFT for the Khuff-C gas/brine Previous HitsystemNext Hit and condensate-A, B and C/brine Previous HitsystemNext Hit, over a range of temperatures and pressures, are reported. Also, results of contact angle for various samples of condensate/brine/rock material Previous HitsystemNext Hit are documented. The IFT between the Khuff-C gas and brine decreased with increasing temperature at Previous HitreservoirNext Hit pressure. Condensate composition affects IFT values for various condensate samples (from Khuff-A, B, and C). Contact angle values for Khuff-C gas/brine/rock material Previous HitsystemTop decreased with both temperature and pressure.
