بررسی شیل‌های سازند گرو در منطقه لرستان به عنوان منابع نامتعارف هیدروکربنی

Nowadays because of the increase in both price and demand for fossil fuel, the unconventional resources are becoming more important in most countries. gas shale is one of the important unconventional reserves. gas shale is fine grain rocks, and has economic gas reserves. gas shale formations have very low porosity and for have, economic production fracturing is essential. in this study, investigate garue formation shales in lorestan district (case study of babaghir 1 well-cutting samples) as unconventional reservoir. garue formation is consisting of alternation of black clay limestons bearing radiolar and blackbituminousshale bearing.plankton and radiolars show deep marine basin, and microfossils show thatgarue formation age is neocomian to knyasyn.geochemical data show that garue shale formation is good quality (profit area of toc). in addition, kerogen in garue shale formation is type iii, and show gas sources rock for garaue shale. in addition, this data confirm deep marine facies for garue formation. mineralogy studies show that, garu formation consist of the clay content less than 4% (4-3%), and the brittleness index is sutable
