Wellhead Services Inc. (WSI) specializes in Wellhead Isolation Tools (WHIT), engineering design, high-pressure operations, and global technical support. With over three decades of combined expertise in fracturing, coiled tubing, cementing, and mechanical engineering, WSI delivers certified tools and world-class field execution.

Wellhead Isolation Tool (WHIT)

Modern stimulation operations frequently demand pressures and flow rates that exceed the ratings of installed production trees and wellheads. Traditionally, this mismatch forces operators to replace critical surface equipment—often requiring the well to be killed, increasing non-productive time, elevating costs, and introducing unnecessary risk to the formation.

The Wellhead Isolation Tool (WHIT) provides a proven, efficient alternative. Designed to isolate stimulation and flowback pressures within the tool itself, WHIT enables high-pressure operations to be safely performed on wells equipped with lower-pressure production trees and wellheads—without equipment replacement and without compromising well integrity.

Rated for high-pressure service and engineered to contain abrasive and corrosive fluids, WHIT protects expensive valves, fittings, and sealing elements from erosion and chemical attack. By isolating the production tree and wellhead from stimulation loads, WHIT significantly extends equipment life, reduces maintenance exposure, and safeguards long-term asset value.

Deployment is streamlined and operationally flexible. WHIT can be installed on dead or live wells, without the need for a workover rig, allowing operators to minimize downtime and maintain operational momentum. Its robust, unobstructed bore design supports high-rate pumping and seamless integration with stimulation, wireline, and coiled tubing operations.

By eliminating unnecessary well intervention, reducing surface equipment exposure, and improving stimulation execution, WHIT delivers measurable gains in safety, efficiency, and cost control—while preserving the integrity of critical wellhead infrastructure

Products

Oscillating Greasing System (OGS)

Revolutionary Self-Automated Lubrication Technology that creates a sealed body cavity that enables grease to oscillate back and forth within the cavity. This oscillation mechanism prevents grease from escaping during valve operation, whether in open or closed positions.

Integrated with SLSM & OGS Systems

The Tri-Seal system provides triple-redundant sealing protection, working in conjunction with our Self-Lubricating Seal Management (SLSM) and Oscillating Greasing System (OGS) technologies to deliver unparalleled valve reliability.
