Kick Fundamentals /17 0 votes, 0 avg 0 Created on April 07, 2023 Kick Fundamentals KF-(number) 1 / 17 What is the main Well Control reason for measuring the mud weight and viscosity at the pits? To ensure the mud program is followed To follow the instructions of the mud engineer To make the mud logger happy To provide information and ensure the proper mud weight is pumped into the well 2 / 17 Use the information below to answer the following question: Mud weight = 10.2 ppg Well MD = 12 000 ft Well TVD = 10 000 ft Formation pressure = 5500 psi Drill string pressure loss (friction) = 2500 psi Annular pressure loss (friction) = 500 psi What is the well condition? The well is balanced with pumps on but overbalanced with pumps off The well is overbalanced with pumps on and off The well is hidrostatically underbalanced with pumps off but overbalanced with pumps on The well is underbalanced with pumps on and off 3 / 17 Which of the following is a “physical barrier”? Monitoring the trip tank Well control drills Flow check procedures Cement 4 / 17 What would be an indication provided by the Pressure While Drilling (PWD) tool that indicates a kick while drilling? Higher Weight On Bit (WOB) and torque Reduction in Equivalent Circulating Density (ECD) Increase in gas content Decrease in mud compressibility 5 / 17 Considering the drilling practices below, which is the most appropriate when drilling a gas-bearing top-hole formation? Control your Rate of Penetration (ROP) Increase your pump rate to maximize your ECD Increase your mud weight by 1.0 ppg Pump faster while increasing your mud weight regularly 6 / 17 Which of the following indicators may warn of an increase in formation pressure? ROP Torque RPM All of the above 7 / 17 What is kick tolerance? The minimum volume of gas that can be taken and the well sucessfully shut-in The maximum volume of influx that can be taken at a given depth and circulated out without exceeding the fracture pressure The maximum volume of water kick that can be taken and allow the well to be successfully shut-in The maximum volume of oil kick that can be safely circulated out of the well 8 / 17 What is a good practice when there is an increase in connection gas? Increase the mud viscosity Increase the rate of penetration (ROP) Increase the mud weight Reduce the mud weight 9 / 17 Use the information below to answer the following question: Well Depth = 10200 ft TVD / 12200 ft MD Mud Weight = 10.2 ppg Bit Size = 8.5 inch Open hole capacity = 0.0702 bblf/ft Drill Pipe capacity = 0.01776 bbl/ft Drill Pipe Metal displacement = 0.0065 bbl/ft Casing shoe depth = 8000 ft TVD/MD After drilling from 12200 ft to 12450 ft MD, what should the pit level have decreased? 17.6 bbls 1.6 bbl 4.4 bbls 15.9 bbls 10 / 17 The well is flowing with pumps off and there is a gain in the pits.but when the pumps are on, the gain stops. What could be happening downhole? The well is overbalanced with pumps on but underbalanced with pumps off The well is underbalanced and the mud weight should be increase by 1.0 ppg The well is ballooning There is a kick in the well. Prepare to start the Volumetric Method 11 / 17 What is called the highest surface pressure if the well is shut-in due to an uncontrolled flow of gas to the surface? Maximum Allowable Annulus Surface Pressure (MAASP) Maximum Allowable Mud Weight (MAMW) Maximum Anticipated Surface Pressure (MASP) Kick Tolerance 12 / 17 You are drilling ahead with a 12.25″ bit with an average ROP of 125 ft/hr. For the last hour, there has been no change to the pit level. What should be done? Perform a flow check Continue drilling ahead Prepare to strip back to bottom Inform supervisor about losing mud to the formation 13 / 17 What is the reason for a pit drill? To test the alarms To help derrickhand understand the mud program To ensure the well is not flowing To train the crew to recognize and react to a kick 14 / 17 What will be the effect of expanding gas on the Equivalent Circulating Density (ECD) measurements with Pressure While Drilling (PWD) tools? Increase the ECD ECD will not change Decrease the ECD There is no way to know 15 / 17 Which of the following actions should be taken while drilling throught a transition zone? Monitor connections and the flowback trends Reduce RPM Increase pump rate (SPM) Increase the Weight On Bit (WOB) 16 / 17 While making a connection, extended flowback time is experienced and decision to shut the well in is made. SIDPP = 170 psi SICP = 170 psi What is the procedure to verify if the long flowback time is due to balloning formation or an influx? Open the BOP and drill ahead watching your pit level Bleed off the surface pressures in steps and circulate a bottoms-up through the remote choke Increase the mud weight by 1.0 ppg Circulate through the remote choke holding at least 100 psi of safety margin 17 / 17 You are drilling ahead with a 12.25″ bit with an average ROP of 50 ft/hr. For the last hour, there has been no change to the pit level. What could be happening downhole? Formation fluid might be flowing into the well All is okay as the pit level is contstant Inform supervisor about losing mud to the formation Mud viscosity might be changing Your score is LinkedIn Facebook Twitter VKontakte 0% Restart quiz Please rate this quiz Send feedback
