Umbilical-Less Tubing Hanger Installation Controls System
Offshore Technology Conference, 2021Abstract The umbilical-less tubing hanger running installation tool, ROCS ("Remote Operated Control System") was first introduced as an R&D project to the market in early 2020. By February 2021, it is in operation for Aker BP in the North Sea on Deepsea Nordkapp. ROCS is specifically designed to increase the robustness

Strength design method for tubing hanger of subsea christmas tree against big temperature difference
China Ocean Engineering, 2014The tubing hanger is an important component of the subsea Christmas tree, experiencing big temperature difference which will lead to very high thermal stresses. On the basis of API 17D/ISO 13628-4 and ASME VIII-1, and by comprehensively considering the erosion of oil and the gravity load of the tubing, a calculation model is established by regarding ...

Wireless Tubing Hanger Deployment in Deepwater Environment, the Bonga Field Experience
Offshore Technology ConferenceAbstract The deployment of Tubing Hangers (TH) in offshore subsea wells is a critical aspect of oil and gas production systems. The Tubing Hanger is a key component in well completion, allowing for the suspension of tubing, communication of hydraulic and electric functions downhole, and sealing the annulus. The installation and retrieval

SPE/ICoTA Well Intervention Conference and Exhibition, 2020
Abstract A producing well located offshore Congo was equipped with a TRSCSSV which failed to open. A velocity valve, with a stem beneath, had been installed to keep the flapper open. This condition, apart from restricting the production, was a temporary solution as defined in Eni's (the operator) well integrity policy; for this reason ...

SPE Conference at Oman Petroleum & Energy Show
Abstract A case study review for two ultra-high sour (28% H2S) high-pressure high-temperature (HPHT) gas wells, each with a stuck gauge hanger causing the wells to be out of production for 6 years. The paper will capture best practices and lessons learned from the successful fishing job which was done after several unsuccessful fishing ...
