چکیده
|
This study deals with the petrophysical analysis of the kahi-01 well in kahi village in the kohat sub- basin (upper indus basin) for evaluating the reservoir potential,using different evaluation parameters in the interpretation equations. three formations namely,lockhart limestone,hangu and lumshiwal formations have been selected for further investigation keeping the fact that they have acceptable ranges for porosity,water saturation and shale volume. the 36 m thick lockhart limestone with dominant limestone content,vuggy and crystalline porosities is appreciated as a hydrocarbon bearing formation. the underlying 50 m thick hangu formation with dominant sandstone content shows that the grain size is coarser. there are three prospective zones identified as; a1,a2,and a3 with comparatively high hydrocarbon saturation and less shale content having the thickness of 7m,15m and 22m respectively,in which a3 zone seems more promising. the underlying lumshiwal formation has 75 m thickness and is dominantly represented by fine to coarse grained sandstone. unlike hangu and lockhart formations,the lumshiwal formation has only few probable zones for hydrocarbon accumulation,however due to the lesser effective porosity values,the formation is not very promising. © 2016 national centre of excellence in geology. all rights reserved.
