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.

19/7/2021· 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 …

Drill Rig Kill Line - Well Control - Rig Worker

10/1/2021· 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. See Figure 10. With

9.2.5: The Well Control System (Blowout Prevention System

The Well Control System or the Blowout Prevention System on a drilling rig is the system that prevents the uncontrolled, astrophic release of high-pressure fluids (oil, gas, or salt water) from subsurface formations. These uncontrolled releases of formation fluids are referred to as Blowouts.Due to the explosive nature of oil and gas, any spark on the surface can result in the …

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

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.

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 …

Well control with one-circulation method - PetroWiki

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
