What is the proper sequence to successfully shut the well in? Stab the Full Opening Safety Valve (FOSV), close the FOSV, open HCR, close BOP, record surface pressures Stab the Full Opening Safety Valve (FOSV), close BOP, open HCR, record surface pressures Stab the Full Opening Safety Valve (FOSV), close the FOSV, close BOP, open HCR, record surface pressures Stab the Full Opening Safety Valve (FOSV), close the FOSV, close HCR, close BOP, record surface pressures 2 / 22 While drilling a vertical well on a surface stack rig, the kicks and the BOP is closed. SIDPP = 450 psi SICP = 700 psi Why is casing pressure higher than the drill pipe after shut-in? There is trapped psi in the casing side of the well. Start bleeding casing pressure off Because the kick in the casing side has a lower density compared to the drilling fluid in the drill string It is necessary to bump the float to get an accurate SIDPP Casing pressure is higher once the kick is in the drill pipe 3 / 22 Why is it important to detect a kick as soon as possible? To prevent gas migration after shut-in To prevent gas expansion while killing the well To minimize the SIDPP and reduce the necessary kill mud weight To minimize the SICP and reduce the risk of formation fracture 4 / 22 What is the quickest way to shut the well in while running a non-shearable tool across a surface BOP stack? Pick up a joint of shearable drill pipe, run into position and install the full opening safety valve (FOSV) Stab and close the full opening safety valve and close the BOP annular Open the vent line on the diverter and close the diverter element Space out properly and close the shear rams 5 / 22 A well is shut-in on a 30-bbl kick. SIDPP = 275 psi SICP = 550 psi If the well had been shut-in on a 15-bbl kick, how would that affect the shut-in pressures? SIDPP and SICP would be higher SIDPP and SICP would be lower SIDPP would be higher and SICP would be lower SIDPP would be the same and SICP would be lower 6 / 22 The well starts to flow in while drilling and the well is shut-in using the hard shut-in. What is the proper sequence to successfully shut the well in? Pick up off bottom, stop rotation, stop pumps, close BOP, open HCR and record pressures Close BOP, Pick up off bottom, stop rotation, stop pumps and open HCR Pick up off bottom, stop rotation, stop pumps, close BOP, close choke and close HCR, record pressures Close BOP, stab the Full Opening Safety Valve (FOSV), close the FOSV, close HCR, close BOP, record surface pressures 7 / 22 A larger kick will give a higher SIDPP and SICP. This is true This is False Depends on the well depth There is no way to know 8 / 22 During a flow-check, it is not possible to determine if the well is flowing. What action could be taken to help measure a small amount of flow from the well? Shut the well in and line up through the mud-gas separator and monitor for flow at the shakers Shut the well in and line up through the mud-gas separator and monitor for flow at the active pit Line up on the trip tank and monitor for a gain in the pit level Line up on the active pit and monitor for a gain in the pit level 9 / 22 Why is SICP usually higher than the SIDPP? Mud in the annulus is usually contaminated by lower density fluids compared to the clean mud in the drill string It is because of gauge issues Mud in the annulus is usually contaminated by low gravity solids This is not true once usually SIDPP is higher than the SICP 10 / 22 What formation characteristics can cause a larger kick volume and higher Shut-in Casing Pressure (SICP)? Type Permeability Ballooning Density 11 / 22 What is the Shut-In Drill Pipe Pressure (SIDPP) after the well is shut-in on a kick? The difference between the hydrostatic pressure in the annulus and formation pressure The difference between the hydrostatic pressure in the drill string and the formation pressure The trapped pressure due to shutting the well in The overbalance in the well 12 / 22 If total losses are experienced while drilling with water-based fluid, what should be done? Stop drilling, fill-up the well with base fluid and monitor Pump lost circulation material (LCM) Continue drilling ahead and monitor the pit level for gains Increaase the mud wejght 13 / 22 Why is SIDPP used to calculate the Kill Weight Mud? It is the most accurate pressure in the well It is lower than casing pressure The drill string is full of clean mud SICP should always be used to calculate the kill weight mud 14 / 22 A gas kick is taken while drilling the horizontal section of the well. If the well is shut-in and the kick is in the horizontal leg, what should the Shut-In Drill Pipe Pressure (SIDPP) and Shut-In Casing Pressure (SICP) read? SICP would be higher than the SIDPP SIDPP would be higher than the SICP SIDPP and SICP would be same Both gauges should read zero 15 / 22 While tripping into the hole at 7000ft the well starts to flow and the decision is made to shut the well in following the shut-in procedure. What statement below is the proper sequence to follow? Stab the full opening safety valve (FOSV), close BOP, close choke Stab the full opening safety valve (FOSV), open HCR, close BOP, close choke Stab the full opening safety valve (FOSV), close the FOSV, open HCR, close BOP, close choke Stab the full opening safety valve, open HCR, close BOP, close FOSV 16 / 22 The well starts to flow in while tripping into the hole and the well is shut-in using the soft shut-in. What is the proper sequence to successfully shut the well in? Close choke, stab the Full Opening Safety Valve (FOSV), close the FOSV, open HCR, close BOP, record surface pressures Stab the Full Opening Safety Valve (FOSV), close BOP, open HCR, close choke, record surface pressures Stab the Full Opening Safety Valve (FOSV), close the FOSV, open HCR, close BOP, close choke, record surface pressures Close choke, stab the Full Opening Safety Valve (FOSV), close the FOSV, close HCR, close BOP, record surface pressures 17 / 22 Why is it important to shut the well in as soon as possible? To minimize the kick volume and reduce the SICP To minimize the kick volume and reduce the SIDPP To make sure SIDPP and SICP will be equal To reduce the amount of time to kill the well 18 / 22 Which of the following will affect the Shut-In Drill Pipe Pressure (SIDPP)? Hydrostatic Pressure in the drill string Annular volume from bit to surface Length of the choke line Length of the surface lines 19 / 22 What can be done to measure a small amount of flow from the well? Close the well and line up through the mud gas separator Line-up to the trip tank and monitor any gains or losses Line-up through the choke manifold to the mud gas separator Line-up to the active pits and monitor for gains or losses 20 / 22 Considering the options below, when is a flow check most likely carried out? After the rate of penetration has increased by 5% Before each tour Before pulling BHA up through the stack If the mud logger requested it 21 / 22 What should be done if a sudden increase in gas level is detected in the fluid? Check for flow Monitor the pit level for losses Run the driller off Increase the mud weight by 1.0 ppg 22 / 22 The well starts to flow in while drilling and the well is shut-in using the soft shut-in. What is the proper sequence to successfully shut the well in? Close BOP, Pick up off bottom, stop rotation, stop pumps and open HCR Pick up off bottom, stop rotation, stop pumps, open HCR, close BOP, close choke and record pressures Pick up off bottom, stop rotation, stop pumps, close BOP, close choke and close HCR, record pressures Close BOP, stab the Full Opening Safety Valve (FOSV), close the FOSV, close HCR, close BOP, record surface pressures Your score is LinkedIn Facebook Twitter VKontakte 0% Restart quiz Please rate this quiz Send feedback
