Advancements in Well Tool Technology: Introducing the LiMAR Uni-Tool®
The demands of modern wells have outgrown the capabilities of traditional tool packages. While standard pulling tool technology has seen little change for decades, significant advancements have been made in slickline tools, toolstring, and winch units. Modern slickline wire is now 3-4 times stronger, necessitating the use of power jars in slickline toolstrings. This increased impact capability often exceeds the design limits of standard pulling tools, leading to tool damage and expensive fishing operations.
The LiMAR Uni-Tool®: A High-Performance Slickline Solution
The LiMAR Uni-Tool® is a mechanical, slickline-conveyed pulling tool designed to engage external fishing necks on sub-surface devices within the well-bore. It was developed to offer a safe, efficient, and durable solution for setting and retrieving downhole devices. The Uni-Tool® functions downhole like all current-market pulling tools and does not require specialist skills to operate.
Since its introduction, the Uni-Tool has been deployed in various parts of the world and has proven its reliability and effectiveness both in-house and in critical offshore environments. Feedback on the tool has consistently been positive, particularly regarding its ease of use, performance, and reliability.
Don't take our word for it, our clients' testimonial says it all......
"The only standard pulling tool we have in our inventory now, is the LiMAR Uni-Tool ®, we no longer supply anything else to our customers. The strength means we replace parts less and the ease of redress means there is no excuse for operators to avoid what can be a fiddly task with other tools. We opted to go for integral quick connect connections in our inventory reducing the risks of injuries from burs created from continuously installing cross-overs. Again LiMAR has taken a common industry tool and brought it into the future."

Evaluating the Uni-Tool® Performance with Best Wireline Tools
To evaluate the Uni-Tool's performance against current market pulling tools, in-house jar testing was conducted using the LiMAR® Flow Loop and Impact Tester. The Impact Tester is designed to qualify both Coiled Tubing (CT) and Wireline (WL) products. It features a large hydraulic ram and flow loop to handle the high push and pull forces seen in CT work. Additionally, it has a lighter weight, automated ram with an integral load cell and sensors, enabling a high number of jarring cycles in quick succession.
The impact testing utilised the LiMAR® Kinetic Adjustable Spring Jar & Accelerator combination to generate the necessary impact force. For each new tool test, the Accelerator Belleville Washers were replaced to ensure consistent and fair impact force. The LiMAR Spring Jar Calibration Sub was also used regularly to maintain consistent jar firing settings.
Three jar settings were selected for the experiment: 500 lbs, 750 lbs, and 1,000 lbs. The goal was to achieve 250 impacts at each setting before progressing to the next higher setting. The results were impressive, showcasing the high performance and durability of the Uni-Tool® in demanding well intervention scenarios.
