STUDY KINDS OF MINERAL ROCKS EXTRACTED DURING THE DRILLING OF OIL WELLS TO BUZURGAN FIELDS

Abstract

In This research study rock and mineral extracted during drill oil of wells in Buzurgan fields located 75 kilometers east of the proving of Missan. and relying field dada by group of wells of wells have been drilled in region by 48 wells  by a group of drilling companies , After drilling data analysis to clips sampling By (Mud logging unit) it is an  integrated unit of the inspection devices rock crumbs and evidence gas and 0il , which  often present from the highest point of  drilling of oil be to an end  within the drilling site and drilling varies between depth   (4000 - 41000) m  The study results showed the contain multiple  rocks and different shapes . since the area sedimentary rocks that can be crumbs sand and mud or be chemical rocks (Dolomite & Limestone) which are carbon rooks through which oil exists. But the mineral rocks which(Miner Clay) percentages with other rocks. degrees by different depth of the wells and the type of rock material down to the presence of a good amount of oil and stop drilling process.
