Method and apparatus for controlling down hole pressure during an offshore drilling operation is disclosed. The method and apparatus are particularly useful for drilling in deep water from an offshore surface facility which includes a drilling vessel stationed above an ocean floor drilling site in which well head equipment is eedded. A marine riser is connected to the well head equipment and
Transcript Removing trapped gas from the BOP SUBSEA WELL CONTROL 1 SUBSEA STACK DIFFERENCES • Choke and kill line connected directly to stack • Choke and Kill lines are Manifolded so that either can be used for circulation and returns during a kill operation • Use of blind/shear rams are used in place of ordinary blind rams • Rams are equipped with integral or remotely operated locking
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.
Well Control Equipment - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Well control is the technique used in oil and gas operations such as drilling, well workover, and well completions to maintaining the fluid column hydrostatic pressure and formation pressure to prevent influx of formation fluids into the wellbore.
Stainless Steel Killing Tunnel Standard Features. Two models are available to work with either KILL16 or KILL22 killing line conveyors. s are killed as they enter the tunnel on shackles. The tunnel base is tapered with a drain hole. Both sides have wash nozzles with trigger valves and hose to keep tunnel washed down at intervals.

26/4/2017· Another way of labeling kicks is by identifying the required mud weight increase necessary to control the well and kill a potential blowout. For example, if a kick required a 0.7-lbm/gal (84-kg/m 3) mud weight increase to control the well, the kick could be termed a 0.7-lbm/gal (84-kg/m 3) kick.
Bullheading is an unconventional well control method and the whole process of killing gas wells is divided into three stages. Stage one (shown in Figure 1-a): The well is shut in and weighted mud is pumped into the well from the kill line or drill stem or both of them simultaneously. Natural gas in the well is compressed. Formation pressure is

Killing, Kill Line & Plucking Equipment . PoultryProcessingEquipment manufacture and supply a complete range of equipment and systems to produce high quality plucked chicken. This process starts with the hanging of live s into stainless steel shackles, suspended from …
Weight Up (add the mud weighting additives) to the desired density – this is the Kill Fluid used to Kill the Well; Circulate the kill fluid through the kill line, down the wellbore, and out of the choke (see Figure 9.12) using an industry standard method: The Driller’s Method; The Weight and Wait Method
Tarim Oilfield super high-pressure gas well control equipment is mainly summed up in 2003. before the Tarim oil field well control experience and lessons, e specially the well Dina 2 on the basis
Oil well drilling is a complex operation and the drilling industry engages the services of personnel and a complied array of machinery and materials to drill an oil/gas well to depths greater than 6000 meters, The drilling industry has seen technological progress, however, these advances have not changed the fact that, besides the use of complied machinery, successful drilling is a
if control pressure is lost Allows a kill-line connection for pressure testing, injection, or killing the well Allows tools to be introduced and run into the well through the swab valve Flowhead Multifunction flow control from the top of the well The flowhead supports the test string and provides a means of surface well control when com-
19/7/2021· Circulation through both choke and kill lines may be necessary. Slow circulation pressures should be taken through the riser, choke line and choke and kill lines, using the mud pumps and the cementing pump. Formation breakdown is likely, as kill mud enters the choke line. Diverter use is discouraged except when displacing the riser with mud.
31/10/2018· And let us add that the stack has two hydraulically actuated BOP mounted valves (one on the choke line and the other on the kill line) [6, 7]. Therefore to now sum the quantity of supply and return hydraulic hoses required to control the functions of this stack if it were underwater would be: Annular preventer2 each 1 in. nominal diameter
The choke manifold is support equipment of hydraulic BOP for controlling well blow out and well pressure. Furnished with hydraulic control panel to achieve remote control. Through the choke valve, perform well killing, replacing polluted slurry in well, and control wellhead pressure of casing and standpipe, restoring mud to control pressure at well bottom to stop overflow.

shown on the conventional kill sheets through one or . at . most two nuers -the maximum casing pressure ( or kill line pressure for offshore floating vessels ) at which the casing shoe fracture or casing burst will occur Fig l. References and figures at end of paper. .
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 wellbore. As the pump is 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 brine is being circulated.
DeltaP = pressure drop across the choke line. The well killing procedure is as follows: ·Close in the well, record Pa and Pdp. (Note the difference between kill-and choke line pressures, as the choke line contents has changed during the process of closing-in the well). ·Displace kill-and choke lines to …
22/12/2017· 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 the gas.
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.
Then we can use verbatim for miscellaneous ’other monospace’ like keyboard shortcuts: “either C-c C-c or C-g is likely the most useful keybinding in Emacs”, or file names: “I keep my configuration in ~/nfig/doom/ ”, among other things. Then, styling these two cases differently can help improve clarity in …
