Clay Properties in the Mukdadiya Formation for Drilling Fluid Production from Shorau and Shewsoor, N Kirkuk, Iraq

Abstract
The present study involves assessing the potential of the clay layers in the Muqdadiya \r\nFormation (late Miocene–Pliocene) for use in oil well drilling fluids. It is achieved through \r\nconducting various tests on the samples under investigation and comparing the results with \r\nthe standard specifications for drilling fluids set by the American Petroleum Institute (API). \r\nThe study also compares the effectiveness of different additives in improving the local clays \r\nand the impact of adding XC-polymer on the current wicking values. It has been found that \r\nXC-Polymer possesses superior properties compared to other polymers when used in the \r\nsame concentrations. This substance is extremely important due to its direct correlation with \r\nthe operation of drilling fluid. The test was used to determine that the two research models \r\n(Shorau and Shewasoor) at their usual concentrations did not produce the necessary \r\ncharacteristics of the drilling fluid in accordance with API requirements. Appropriate \r\nspecifications for the drilling fluid were obtained by conducting a series of laboratory tests, \r\nincreasing the model\'s concentration to 25 grams, and adding high-viscosity CMC and XCPolymer to the sample in order to assess the current properties of the two study models in fresh media. The Shurao (M1) and Shewsoor (M2) models did not show current properties suitable for drilling fluid in salty media. After adding XC-Polymer to 25 grams of the models activated with 4 grams of Na2CO3, the two study models showed a response to the activation \r\nprocess and obtained results for current properties suitable for drilling operations in salty \r\nmedia.
