In support of improving communication and technical awareness for coiled tubing, wireline, slickline, and jointed pipe intervention operations, we collaborate with other professionals to publish research in partnership with organizations like ICoTA and The Society of Petroleum Engineers. We enjoy working to improve the technology used to advance and optimize coiled tubing intervention on topics such as extended reach, tubing forces, tubing fatigue, dynamic forces, and others. A selection of our research work is included below.
Please Contact us to see if we can help you develop a new product or verify the efficacy of a new intervention technique with a software model.
