Table 11 Downhole technology for extended research, horizontal and multilateral / multibranch wells


RTD TOPICS/ OBJECTIVES Category
1. To develop improved production logging tools for use with 2 and 3 phase flow TE in horizontal wells: - tools to cope with phase segregation in long horizontal sections. 2. Modelling wellbore flow and inflow performance in horizontal wells especially TE + E for long term performance prediction: - evaluation/prediction of pressure drop in horizontal wells. 3. To develop improved, benign drilling and completion fluids for difficult TE hole/extended reach service. 4. To optimise all drilling and downhole technology aspects impacting on the cost- E + TE + CR effective exploitation of multilateral / multibranch technology, including: - production logging, with advances in general design for service in horizontal sections; - improved methods for pressure drop detection; - downhole completions optimisation; - efficient well servicing; - candidate selection for permanent instrumentation for reservoir and downhole technology monitoring. (Asset focus of the above topics: all field developments and improved recovery from existing fields) TE- technology enhancement. CR- cost reduction. E- enabling.
