The output increased significantly!
The liquid volume (234 bbl / D to 1400 bbl / D) increased by 5.98 times.
The yield (99 bbl / D to 546 bbl / D) increased by 5.5 time
HB oilfield B19block——B19-29
Well B19-29：The reservoir is medium porosity and permeability. The faults in the east and north of the structure are developed. In order to evaluate the remaining oil potential at the lower part of K1baIII layer, the T-type branches were built in the vertical direction of the structural contour.

The picture of T-type well operation
HB oilfield B19block——B19-29
When the T-type branches were built, the preliminary effect is not obvious. But after a period of water injection to supplement energy, the production increased gradually.
HB oilfield B19block——B19-29
After the implementation of T-type multi-branch technology in this well, the cumulative oil production was 3964 tons, and the cumulative liquid was 9058 m3 . The well production is very stable at present.
