VOLUMETRIC WELL CONTROL - Drilling Manual

Once gas is at choke stop the bleed operation and start pumping mud into the well using the kill line. The procedure for lubriion: A- Let kill and choke line pressure equalise. B- Open kill line stack valves. C- Pump slowly into kill line. D- Pump 3.6 bbls mud into annulus. E- Allow the mud time to fall through …

Petroleum Engineer: Seputar Killing Well

Kegiatan awal untuk mengamankan keadaan sumur disebut dengan Killing Well (mematikan sumur) yang dapat dilakukan dengan beberapa cara. 1. Tekanan formasi . Tekanan formasi adalah tekanan yang berasal dari fluida pengisi pori-pori dari batuan formasi. Pada proses kompaksi sedimen, tekanan pada lapisan di bawah akan terus bertaah seiring dengan penaahan lapisan dan tekanan di atasnya

Advanced blowout & well control | Robert D. Grace ,Bookzz

Figure 1.2 f8 Advanced Blowout and Well Control Figure 1.3 It is unusual for dry gas to erode. A production well blowout in North Afiica was producing approximately 200 mmscfpd. The dry gas eroded through the tree just as the well was being killed. It had been blowing out for approximately four weeks.

DrillingForGas - Well Control - Volumetric Method

1.Close the surface kill line valve and open the kill line valve at the BOP stack. 2.Wait until mud from the kill line is replaced with gas. This will be indied when kill-and choke line pressures are equalised. 3.Pump a small amount of mud 0.3-0.6 m3 (2-4 bbl) into the kill line and let the kill- and choke line pressures equalise.

Choke Line - an overview | ScienceDirect Topics

Howard Crumpton, in Well Control for Completions and Interventions, 2018. 14.1.5 Choke line friction. When circulation returns are taken through the choke, a significant pressure loss is seen. This is caused by friction losses in the small diameter choke line between the subsea BOP and the rig floor. This pressure drop is observed during slow circulating rate measurements when circulating

DrillingForGas - Well Control - Balanced Mud Method

It is possible to avoid the necessity to take the choke line pressure drop into account during well killing operations by using the kill line as a pressure conduit to monitor Pa at the subsea BOP stack (kill line fail safe valves open and the kill line valve upstream of the choke closed). Normal well killing practices can then be applied without the need to take the choke line pressure drop

9.2.5: The Well Control System (Blowout Prevention System

An explosive blowout and the failure of the Well Control System were the causes of the Mocondo Well disaster that killed eleven of the rig crew on the Deep Water Horizon Rig on April 20, 2010 and resulted in 35,000 to 60,000 bbl/day of crude oil to spill into the Gulf of Mexico. We will discuss this later in the lesson. In the detailed rig schematic (Figure 9.02e), the well control system is
