The inability to accurately and safely determine the location of tool string components within Pressure Control Equipment (PCE) presents operational challenges for both service providers and E&P’s. The negative results of incorrectly closing PCE or operating well intervention equipment without empirically knowing the location of key tool string and BHA components has resulted in significant HSE events and monetary costs.
Intelligent Wellhead Systems has developed the inVision Offshore System; a technological innovation that measures and visualizes the presence of coiled tubing, wireline and associated components within pressurized zones of the PCE stack. Providing users with the critical knowledge of knowing when it is safe to close PCE and/or stop equipment hence saving time and reducing risks.
In collaboration with BP America and Oil States Energy Services; Intelligent Wellhead Systems performed a technical trial of the inVision Offshore System during interventions on BP assets DC311 and DC133.
The intent of the technical trial was to demonstrate the application of this technology in coiled tubing, wireline and slickline interventions.
The Gen 2 inVision System performed as per OEM specs over the course of 2 months on multiple slickline, wireline and coiled tubing runs. The system saved time, eliminated HSE risks, provided peace of mind to rig operators performing critical tasks and gained user confidence over time.
Intelligent Wellhead Systems is committed to continual development of the inVision Offshore System to fully realize the technologies potential and further assist offshore operations in safely and efficiently achieving their goals.
Intelligent Wellhead Systems through a joint venture with Trendsetter Engineering, is developing a subsea inVision System– currently undergoing preliminary testing.
This project allows the inVision System to be placed at key locations within the riser assembly enabling the same advanced technology to be used subsea. Figure 2. Illustrates the placement of three systems in a deep water intervention. The upper system functions as described in this technical trial report; the two remaining systems are subsea, located above the lubricator valve and subsea tree.
The advantages presented by the inVision System technology in this configuration are numerous and represent a significant technological and procedural advancement for offshore intervention operations.
