Managed Pressure Drilling Equipment

Kapwell Offshore rig equipment set deals with narrow margins between pore and fracture pressure generally are smaller than on land rigs or in shallow water. Therefore one of the key challenges in conventional deepwater drilling and in Managed Pressure Drilling, in particular, is to mitigate and operate within this very narrow pressure window.

On the well control side MPD helps to bring very small kicks, and limiting the kick size means a maximum chance for success for a kill, also minimize any potential for wellbore damage. When you buy a package, Kapwell delivers “plug and play” system.

Kapwell delivers MPD equipment set in compliance with API and DNV specification. Reports and sizing calculations and reports are prepared for the third party or client approval ensuring equipment set suitable for kick detection, fluid separation, etc.

Control System

Industry proven MPD software (third party) integrated to MPD hardware provide a range of control options—automatic, semiautomatic, and manual.

Choke Manifolds

Choke manifold customized to include dual flow lines, dual chokes, necessary to manage the surface backpressure in MPD and UBD operations.

The choke manifold consists of Type B gate valves, API certified hydraulic chokes and adjustable chokes. The choke manifold sees very rugged service during the well kill procedure. Choke manifolds throttles mud, sand and gas as they leave the well.

Flow Measurement System

Together with choke manifold, Coriolis mass flow installed to measure gas-flow velocity, temperature, and pressure to determine actual and standard volumetric flow as well as mass flow rates.

Choke Control Panel

MPD Choke Panel available in two options, manual and automatic, manual MPD choke Panel are traditional Choke Panel require regular intervention. Automatic MPD choke Panel operate based on input set point pressure against Coriolis flow meter and our PLC controls the auto Choke which in turn controls the fine incremental flow control adjustments that way persistent annulus surface’s back-pressure during all MPD applications or underbalanced drilling

Liquid Seal Monitoring

The Liquid Seal Monitoring System is an instrumentation system mitigates the risk of liquid seal loss during well control operations. The Liquid Seal Monitoring System includes; Pressure and temperature sensors/transmitters kit to be installed on MGS PLC enclosure (mounted separately) Liquid seal display panel with alarms and pressure differential readouts.

Rotating Control Device

Our MPD equipment suitable to work with automated Rotating Control device (RCD) offering automated control and safety in diverting well returns to a surface separation system during managed pressure and underbalanced drilling applications.

High Rate Mud Gas Separator

High rate Mud Gas Separator specially designed for MPD operation, handles a high rate and high proportion of mud solids and sour gas.

While drilling with an underbalanced mud column operation may experience hydrate plugging as a result of gas expansion through the choke. The liquid seal ensures that separated gas vents safely without breaking through to the mud tanks.
