WellMend

WellMend NanoCoil solution is an innovative service that offers inspection, repair and rectification of safety valve control line problems rather than replacing the entire production tubing. This prevent long and costly periods of down time which in turn would lead to significantly reduced repair cost and increased production efficiency for the oil companies and in turn lower lifting cost per barrel produced. Reduced downtime and repair cost for safety valves with faulty control lines represent the main challenges that this WellMend NanoCoil solution. The hydraulic control line tubing typically has an inner diameter of 3.6 mm, the tubing length ranges from 200 to several hundred meters, and several bends in the tubing create restrictions. Chemicals used to mend leakages have high viscosity, and the tooling pipe must be able to transport such chemicals even though the inner diameter is very small, typically 1,5-2mm. Potential customers for this service are oil and gas companies that operates in areas with regulations that require functional safety valves in order to produce hydrocarbons. The North Sea and US Land are examples of areas with such regulations.
