1. Product Overview
The kill manifold is key well-control equipment. It provides a controlled path for pumping kill-weight drilling fluid into the wellbore to establish the required hydrostatic pressure and control a kick.
It works with high-pressure pumps, kill lines and wellhead equipment for kill-fluid injection and other approved well-control circulation operations. Controlled bleed-off is routed through the choke side of the well-control system; squeeze-cementing service must be confirmed for the ordered configuration.
The check valve permits flow toward the well and helps prevent reverse flow; it is not a substitute for a positive-isolation valve.
2. Design Features
Designed to the applicable requirements of API Spec 16C when specified. For sour service, wetted metallic materials are selected in accordance with NACE MR0175/ISO 15156 for the stated service environment.
The manifold can be configured with high-pressure pump units and wellhead equipment for kill-weight-fluid injection and well-control flow-path switching.
Valve, check-valve and line arrangements are selected to provide the required injection, isolation and non-return functions under the approved well-control procedure.
Configuration-specific layouts are manufactured to the approved drawing, stated rated working pressure, end-connection specification and wellsite interface requirements.
