Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
In the past few years, the Effect of Capillary Pressure Curves on the Non-wetting and Wetting properties of fluid flow was the topic of several papers. This effect was usually examined by applying different EOR methods on the structure of pore space of cores made up of blocks of pore size distribution. In this paper, Capillary Pressure is created in the core by partial filling of the pore spaces with oil and injecting with Nano-particle solutions (NPS) which are used in EOR recovery to influence the pore size on core, and to create a core plug of heterogeneous wettability. The outcome of heterogeneous wettability on the capillary pressure is shown in a systematic way by the centrifuge technique with various concentrations of Nano-particle solutions relevant to the experimental data.The objective of this study is the use of centrifuge to measure capillary pressure. The measurements were performed on a selected core samples using formation crude oil and water. Centrifuge provided the opportunity to measure different capillary pressure curves. The experimental procedure consists of the following steps: (1) the core plug is fully saturated with Nano-particle solution and displaced by oil to reach the initial water saturation. Subsequently, a drainage experiment is performed in order to obtain the initial oil saturation, Soi, (2) the oil is displaced by Nano-particle solution to residual oil saturation, Sor; the experiment known as the imbibition experiment was achieved. This procedure was repeated several times on the same plugs with various rotation speeds, and finally (3) it has been observed that a change in the capillary pressure curve occurred when NPS is used with different concentrations.
