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.
Interested parties should contact Dr William Buckman at www.buckmanjetdrilling.com
