Table 6 Well productivity and improved recovery
RTD TOPICS/ OBJECTIVES Category
1. To develop lower cost, more reliable and widely applicable technology to effect E + TE + CR
produced water-shut off in reservoirs.
2. To improve understanding and management of injected fluid dispersion in TE + CR
water and gas flooding.
3. To improve capability for water and gas (WAG) IOR technology through: TE + E
- improved understanding of sensitivities with respect to reservoir
heterogeneity;
- improved candidate selection.
(Asset focus of the above topics: field development and production)
4. To improve understanding of gas condensate production processes in near TE + E
well bore region, for example through:
- enhanced experimental methods for studying gas condensate processes;
- improved understanding of the effects of finite gas solubility on flow
processes and production;
- better understanding of oil mobility at low oil saturation associated with
condensate drop-out around producing wells;
- optimisation of gas recycling.
(Asset focus: HP/HT field development and production)
5. To develop more effective screening tools for selecting candidates for different TE + E
IOR processes as a pre-requisite for optimal use of an IOR toolkit.
6. For chemical IOR technology, to develop systems more robust to TE + E
geological/temperature uncertainties; flow diversion technology stable at
HP/HT conditions; relative permeability modifiers; intelligent systems which
seek out high water saturation zones; novel methods for improving viscous oil
recovery (e.g. downhole heating)
7. More generally, to improve understanding of sensitivity of fluid flow and TE + E
residual oil saturation to kinds of reservoir heterogeneity.
(Asset focus of the above topics: improving recovery and extending life of
existing fields)
TE- technology enhancement. CR- cost reduction. E- enabling.
