Wellbore chemical inflow profiling at Shell's Cutter AB ///

Shell’s Cutter development is notable for a number of industry firsts, in particular the use of wind and solar technologies in the production of natural gas, Fig. 1. Another industry first is the use of chemical paint on tracer materials that can highlight areas of inflow along the wellbore simply by sampling the hydrocarbon stream at surface for the tracer’s presence. This enables basic downhole flow information to be obtained at a fraction of the cost compared with a PLT. Field background Cutter field is in the southern sector of the North Sea, 75 mi (120 km) from the Norfolk coast. It exports the gas through 175 km of subsea pipelines to Bacton Gas Plant over the Shell-operated Carrack and Clipper platforms. The design of the Cutter field Trident monotower is based on offshore wind turbines. The monotower’s lower construction and operating costs enable the access and recovery of small resource pockets...
