Question No 2 CASE STUDY-2 The drilling fluid program is designed and selected according to many factors and criteria for successful drilling operations. The better the drilling fluid is designed and selected, the more efficient and effective drilling operations are possible. Answer the following Questions. i. Discuss the factors affecting the drilling fluid selection. ID Describe the role of mud density for the successful drilling operations and also explain the potential problems during drilling operations if there are changes in mud density. iii. Describe the relationship between plastic viscosity and overall drilling performance. iv. Identify the parameters affected by the changes in Plastic viscosity which may affect the drilling performance. (4x10=4 , 3, Required Swipe or tap to select text. Answer the following questions using above data, 1. Identify the type of influx inside the wellbore. ii. Identify the causes of this kick situation iii. Estimate the volume of the kill mud required to kill the well iv. Determine the time required to kill the well. v. Estimate the initial safety margin before fracturing the formation at the weakest point in the open hole section vi. Estimate the final safety margin before fracturing the formation at the weakest point in the open hole section vii. Design the kill mud weight required to kill the well viii. Identify the bottom hole pressure to be maintained inside drill pipe to avoid secondary kick. IX Estimate the number of strokes required to pump from the bit to casing shoe? X. Discuss the factors affecting safety margin before fracturing the formation (6x10= 60 marks)
