Abstract
nDrilling fluid used while drilling the layers of shale will have the potential of reacting with water which tends to increase stickiness, induce swelling and promote sloughing of the borehole. This results in the reduction of drilling fluid circulation, increased mud loss, increase in torque and drag, reduction in lubricity. This will ultimately results in the increase of Non-Productive Time (NPT) during drilling which results in increase of Capital Expenditure (CAPEX) to the operators. This can be overcome by adding shale stabilizing agents to the drilling fluid. In this paper, various shale stabilizing agents are added with water based drilling muds which was employed in different subsurface formations and its’ behaviour was studied.
