Technical Overview

What Is a Choke Manifold in Well Control?

Understanding the Choke Manifold Function

The primary choke manifold function on a drilling rig is to manage casing pressure and maintain bottom-hole pressure balance. When a blowout preventer (BOP) is closed, the manifold allows for the controlled release of fluids.

Integrated Choke and Kill Manifold Systems

A complete choke and kill manifold setup provides a dual-layer defense. While the choke side regulates fluid discharge, the kill side allows for pumping heavy drilling mud directly into the wellbore.

Gowin systems are engineered for safe pressure regulation in extreme HP/HT environments.

Safety & Control

Advanced Hydraulic Choke Manifolds
and Control Logic

For high-risk HP/HT environments and Managed Pressure Drilling (MPD), Gowin’s hydraulic choke manifold serves as the frontline of defense. It empowers operators to execute precise surface backpressure adjustments directly from the driller’s cabin, ensuring maximum safety distance.

"This remote capability ensures instantaneous response when managing sudden gas kicks or fluid influx, effectively mitigating risk to rig personnel while protecting critical wellhead integrity."

Our control panels are engineered for API 16C compliance, featuring dual hydraulic circuits for 100% redundancy. We offer customized fail-safe strategies and seamless interlocking with ESD systems to meet the most stringent offshore safety philosophies.

Choke Manifold FAQs

A system of valves and chokes used to regulate surface pressure during well control operations.

It involves a hydrostatic shell test (1.5x WP) and seat leakage tests per API 16C to ensure the integrity of all choke manifold valves.

Yes. We provide a choke manifold manual (PDF), 2D drawings, and 3D STEP models upon request to assist with project engineering.

During a shut-in condition, a choke manifold works by directing well fluids through adjustable or fixed chokes to control surface backpressure. This controlled circulation helps stabilize bottom-hole pressure while safely removing formation influx from the well.

A choke manifold valve is used to isolate flow paths, switch between chokes, and enable safe maintenance under high-pressure conditions. These valves are designed to handle erosive flow and frequent operation during well control events.

A choke manifold line up refers to the specific valve and choke configuration selected to control flow during well control or circulation. Proper line up ensures the correct flow path, avoids dead-end pressure traps, and allows safe switching between chokes when required.

Yes. A choke manifold skid integrates chokes, valves, piping, and instrumentation on a single structural frame. This design simplifies transportation, installation, and commissioning for offshore or remote drilling projects.

The pressure rating of an API 16C choke manifold is determined by working pressure, temperature, fluid composition, and erosion allowance. Proper rating selection ensures compatibility with the BOP stack and well design.
