Well Testing Control Equipment

Reduce risks anywhere with advanced control options

Surface well testing control equipment is essential to assuring your test operations are reliable and accurate as well as responsive when faced with an emergency. The Schlumberger portfolio of well control equipment helps operators safely react to and handle such events—in a variety of pressure ratings and in any operating environment—effectively and quickly.


Used to hang test string from elevator and to control flow through master and flow valves; if fitted with a swivel, it allows test string to rotate. Compatible with slickline and electric line operations.

Surface Safety Valve

Hydraulically actuated fail-safe gate valve for testing oil and gas wells; used to quickly shut in a well upstream of the choke manifold in case of overpressure, failure, a leak in downstream equipment, or any other well emergency requiring an immediate shut-in.

Well Test Emergency Shutdown System

Multistation system that permits closure during testing operations in response to an emergency; remotely and simultaneously controls the flowline valve on the flowhead and surface safety valve.

Floor Choke Manifold

Four manual valves (five if bypass valve is included) used to control flow rate and reduce well pressure before flow enters processing equipment.
