Interface, a Leader in Force Measurement Solutions, Introduces a Pressure-compensated Downhole Load Cell Solution for High-pressure Environments

On February 21, Interface, Inc., the world's renowned leader in force measurement technology, design, and manufacture, introduced the Interface Pressure Compensated Downhole Load Cell, a novel downhole force measuring solution for high-pressure, high-temperature applications (IPCD). The IPCD is a Wheatstone bridge foil-gaged force measurement solution that employs proprietary compensation techniques. It is designed to be used in harsh environments, like those found in the oil and gas industry. It also requires less maintenance than other force sensors on the market.

"The Interface Pressure Compensated Downhole Load Cell provides critical accuracy, dependability, and flexibility to our customers at a modest price,Our hard-earned expertise and experience gained over many decades of engineering force measurement solutions for the oil and gas industry, as well as deep collaboration with our customers, enabled us to bring this first-of-its-kind product to the market."

-Brian Peters, vice president of global sales, Interface

The new IPCD load cell is ideal for high-pressure applications such as wireline and slickline testing and measurement, perforating operations, horizontal drilling, topside and drill-down drilling, and offshore solutions. Interface's load cell is also used for tractor component testing, pipe recovery and set-up of plugs, well service and cleaning, tension line testing, and instrument fishing, among other things.

The IPCD is utilized for conveyance operations in oil wells by mounting the load cell on the head of a wire or slickline and lowering it into the well. This is achievable because of Interface's patented compensating technology, allowing direct pressure measurements from the source. It works by enclosing the compensation, which protects the load cell from heat and pressure while enabling it to gather data beneath. It can also be used in vertical and horizontal wells, which have become more common in recent years because of the rise in fracking and other extraction methods.

Current options on the market are known as "wet load cells," which need regular maintenance more frequently due to the bridge and gage being hydraulically corrected. This compensating approach exposes the sensors to dangerous surroundings and requires an electrical signal from underneath to be relayed to sensors above the ground. This not only degrades the goods rapidly, but it also leads to less reliable statistics. Externally compensated load cells can also not be utilized in suitable horizontal applications because above-ground values are unacceptable.

The interface has released a new technical white paper on the Interface Pressure Compensated Downhole Load Cell. This new paper talks about how the latest version of the load cell was tested and how it worked.
