RADIAL FLOW EQUATION

FLOW RATE (bbl/day) = 2kh(pe – pw)/mu ln (re/rw)

Where

k = rock permeability

h = formation thickness

pe = fluid pressure at outer boundary

pw = fluid pressure in wellbore

mu = fluid viscosity

re = effective drainage radius

rw = wellbore radius

JET DRILLED HOLES INCREASE FLOW RATE BY INCREASING THE WELLBORE RADIUS

STIMULATION RATIO

STIMULATION RATIO = ln (660/0.5) / ln(660/200)= 6.01

THIS SHOWS THAT DRILLING MULTIPLE 200 FOOT DRAIN HOLES CAN

INCREASE OIL PRODUCTION UP TO 6 FOLD

CONCLUSIONS (2015)

This BJD jet drilling technology is fully developed and ready for full scale field implementation

Buckman Jet Drilling is currently attempting to sell BJD to an oilfield service company that can market this technology worldwide.
