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.
