«HYDRA» — Radial Drilling Sub
A sub fitted with titanium needles for forming reservoir drainage channels.
Advantages
- formation of draining lateral channels that increase reservoir oil recovery without the risk of entering unwanted zones;
- larger reservoir drainage area compared with screen (filter) completion;
- reduced job time and cost compared with hydraulic fracturing;
- operations are performed with standard equipment, without additional units.
Specifications
- channel length: up to 10.5 m
- number of channels: up to 3
- channel diameter: up to 12 mm
- number of check valves: 9
- size range: 114/178 mm
Status
The «HYDRA» technology is a domestic multilateral well-completion technology aimed at improving the development efficiency of low-permeability and heterogeneous reservoirs. The radial drilling sub is designed to increase the reservoir contact area and improve the final oil recovery factor: titanium needles form draining lateral channels that boost oil recovery and reduce the risks associated with conventional completion methods.
