State-of-the-art software for K & N correlation to generate capillary pressure curves under different wettability conditions

Abstract

Uzorci jezgre dobiveni bušenjem obično nisu pravi pokazatelj stanja ležišta zbog prodora filtrata isplake. Prodor može izazvati promjene močivosti, što utječe na kapilarni tlak. Kako bi se dobili podaci o kapilarnome tlaku koji je stvaran pokazatelj ležišta, razvijen je set korelacija uz čiju se primjenu mogu generirati krivulje pri bilo kojoj močivosti ako su poznati laboratorijski podaci za svaki uvjet močivosti. Da bi se olakšala uporaba razvijenoga seta korelacija razvijen je i software koji se koristi posljednjim dostignućima programiranja u Visual Basicu.Core samples obtained while drilling are usually not true representative of the reservoir due to invasion of mud filtrate. Invasion can lead to wettability alterations affecting the capillary pressure. So to have a capillary pressure data which is true representative of the reservoir, set of correlations has been developed, capable of generating the curves at any wettability, when the laboratory data at any wettability condition(s) is known. To ease the use of developed set of correlations, software has also been developed by accomplishing state-of-the-art programming in Visual Basic
