The BOP stack, choke and kill lines shall be flushed with water prior to testing (for subsea BOP stack, after the first installation, the tests may be performed using the actual fluid in hole). If a heavy mud, loaded with large amounts of solids is used, particular care in flushing of lines and valves is required.

GSI has pressure control packages suitable for both electric line and slickline support. We can support your land, inland, shelf, and deepwater needs both domestically and internationally. Experienced in PCE and wireline operations, our technicians understand what it takes to be successful.
and well control elements that are enlighten and discussed in this report are the effect of a quick BOP closure, a simulation in the program Drillbench Kick has been conducted to reveal the friction pressure loss in choke line for
A high-pressure pipe leading from an outlet on the BOP stack to the backpressure choke and associated manifold. Choke Line A set of high-pressure valves and associated piping that usually includes at least two adjustable chokes, arranged such that one adjustable choke may be isolated and taken out of service for repair and refurbishment while well flow is directed through the other one.
When . . . The minimum BOP stack must include . . . (1) The expected pressure is less than 5,000 psi, Three BOPs consisting of an annular, one set of pipe rams, and one set of blind-shear rams. (2) The expected pressure is 5,000 psi or greater or you use
Wireline bop blowout preventer is a kind of wireline valve is also named as slickline bop blowout preventer, it is often placed on the surface oilfield between wellhead and lubrior when provide blowout protection, wireline operation, slickline operation, braided line
17/3/2015· The valves in the choke line 25 is opened on the subsea BOP to the high pressure (HP) choke line 24 and the bottom hole pressure controlled by the adjustable choke 22 on top of the coke line on the drilling vessel above the body of water.
Flexible Lines (Blowout Preventer (BOP) Hydraulic Control Line and Flexible Choke Kill Line)features resistance to high-pressure, fire-resistance, heat-insulation and …
A high-pressure line that allows fluids to be pumped into or removed from the well with the BOPs closed. choke/kill manifold An assely of valves, chokes, gauges, and lines used to control the rate of flow and pressure from the well when the BOPs are closed.
Managed Pressure Drilling (MPD) was introduced in 2000 as an adative drilling technology for pricely controlling the pressure profile in the wellbore. Utilizing applied surface pressure, MPD provides an addition degree of freedom in the design and drilling of wells.

These friction pressure losses occurs in the pipes on the rig, in the kill and choke line and in annulus in both relief well and the blowing well. Different simulation tools has been used to run simulations to find out how the friction pressure is affected by water depth (length of kill and choke line), ID; [Internal Diameter] size on kill and choke line and mud-type used.

Choke Line Friction (CLFP) • Used to determine the amount by which the casing pressure is to be adjusted to maintain BHP = FP when starting the pumps on a kill operation. We reduce the SICP by the amount of CLFP to make allowances for the back pressure imposed by the CLFP.
We are seeking to optimize BOP test times by simultaneously testing the choke manifold at surface and the BOP downhole within the same test. An issue that we face is that for some tests, the Maximum Anticipated Pressure at surface plus the hydrostatic of the fluid in the choke lines exceeds 15,000 psi INTERNAL pressure downhole (rated working pressure of the BOP).
The internal pressure connection line 520 of the internal pressure supply unit 500 is connected to the auxiliary line 221 of the riser 220 and is connected to the internal pressure of the BOP bore hole 201 through the kill line and the choke line 205, May be
