18ft killing through kill line well control

Subsea Well Control Initial Circulating Pressure Use Scr

When killing a well from a floater, through the choke line. For example: Using a slow circulating pressure through the choke of 1300 psi, and a slow circulating pressure of 1000 psi up the riser, the choke line pressure loss can be calculated to be 300 psi. Assuming a kick is taken and the following pressures are recorded; All of the necessary kill calculations are made prior to

Surface Test Tree | Flowhead

Surface Test Tree, also called Flowhead, is loed directly on top of the well and is the first piece of equipment that fluid from the well flows through. Its principal function is to control the fluid flow in and out of the well. The flowhead consists of four gate valves: a master valve, two wing valves (flowline & kill line), and a swab valve.

Well control risks on HPHT wells may call for system

• At least one choke and one kill line with HCR valves; • 15,000 psi-rated chokes – usually four chokes with a split buffer tank, because well kill operations can take days and weeks to complete. Normally, two chokes are hydraulic and two are manual, although that’s conventional and we occasionally have manifolds with four actuated chokes; • An updated mud system, with plenty of

US8781746B2 - System and method for obtaining and using

A tool driver activates a telemetry tool when a predetermined threshold of accelerometer data measured by an accelerometer. The threshold preferably corresponds to an acceleration level expected while drilling mud is pumped at a slow pump rate through the well''s drill pipe. When a fluid influx occurs during drilling, the well is shut-in, and the tool driver turns off the telemetry tool.

Choke Manifold Full Guide & IADC Recommendations

If the kill line is not meant to ultimately replace or augment the choke line, it is highly desirable to install a check valve upstream of the stack valves. Note: Choke manifold design should consider such factors as the anticipated formation and surface pressures, method of well control to be employed, surrounding environment, corrosivity, volume, toxicity, and abrasiveness of fluids.


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 …


facilitate subsequent through- tubing pumping and well killing operations. 2. The geometry of the SBR cut should also enable fishing operations. The logic applied to this issue follows that the “Standard SBR” is used within the “working” well control stack arrangement to conduct well control circulation kill operations where time and conditions permit. Where these operations fail to

27. During a well-killing operation, a common way to bring the pump up to kill rate without changing bottom hole pressure is to: A. keep SIDP constant at the original shut-in value by opening the choke. B. keep SIDP constant at the original shut-in value by opening the choke and bringing the pump up to kill-rate speed. C. keep SICP constant at the original shut-in value by opening the choke

kill line | Oilfield Glossary

During normal well control operations, kill fluid is pumped through the drillstring and annular fluid is taken out of the well through the choke line to the choke, which drops the fluid pressure to atmospheric pressure. If the drillpipe is inaccessible, it may be necessary to pump heavy drilling fluid in the top of the well, wait for the fluid to fall under the force of gravity, and then

PEH:Well Control: Procedures and Principles - PetroWiki

Determining the best well-control method for most situations involves several considerations including the time required to execute the kill procedure, the surface pressures from the kick, the complexity relative to the ease of implementation, and the downhole stresses applied to the formation during the kick-killing process. All points must be analyzed before a procedure can be selected. The

the well control stack, close the master valve and replace/ repair the leading riser section. c. Watch for the possibility of the coil not being able to pass the stripper bushing. This is a sign of severe damage and will require killing the well and cutting the coil. d. If it is unsafe to pull out of the hole, with surface pressure present, kill the well. Resume pulling out of the hole. e

The kill line was then closed and the procedure was discussed; during this time, pressure began to build in the system to 1400 psi. At this point, the line was opened and pressure on the kill line

Where are Choke and Kill Hoses used? - Plastics Film

The choke and kill hoses are used on the choke manifold and kill manifold. 1. The function of choke manifold. a. Well killing operations are made through the throttling action of the throttle valve to control the flow of fluid out of the wellhead and also control the wellhead back pressure. The bottom hole pressure is always bigger than the

How do you kill a well?

Kill line is the pumping outlet connected to Mud cross/drilling spool below BOP stack, allow to pump fluid thru it to the annulus while killing/filling operations. What is kill mud? A kill weight mud is a mud with a density high enough to produce a hydrostatic pressure at the point of influx, or where the kick is entering the wellbore, that will be sufficient enough to shut in the well and

Shut down the pumps and close the choke after the kill mud has reached the flow line. The well should be dead. If pressure remains on the casing, continue circulation until the annulus is dead. 10.

Two The kill line can be used as a pressure monitor, assuming the fluid density in the kill line is the same as that in the well bore. As the pump in being brought up to kill speed, the kill line pressure at the surface is held constant. There will be no pressure losses in this line, as no mud is being circulated through it.
