T-type Multi-branch Drilling Technology    

Oil production increased by 6-12 times;

Recovery efficiency of reservoir increased more than 15%

The maxium production of single well after T drilling is 3980ton.

The single well production on off-shore after T drilling is 1100bbls



What can this technology do?

Application 1: Tapping the potential of remaining oil in old oilfields

Drilling through the pollution zone near the well;

Penetrating the remaining oil or dead oil area

Increase oil drainage area and seepage channels;

Improve reservoir connectivity;

Application 2: Developing low-permeability or thin reservoirs

Application 3: Developing the reservoir with active bottom water or top water

 In the process of reservoir development with active bottom water or top water, it is easy to occur "water invasion" or "water flooding" production layer, resulting in the rapid rise of water cut in oil wells. T-type horizontal multi-branch well can directly reach the "high position" of remaining oil, provide a new seepage channel, delay the water coning advance speed, extend  low water cut recovery period.

Application 4: Water injecting accurately

Reduce the water injection pressure and slow down the water line inrush;

Improve the sweep area of water drive and increase the controlled reserves of water drive;

Application 5: Revive of the casing damage well

Application 6:  Multi-branch completion in new well

According to the geological characteristics of the target interval, T-type drilling technology can be used in the new well completion,  replacing casing perforation, fracturing, horizontal sidetracking and other completion methods. To realize multi-channel three-dimensional development of oil wells.
