"Refracturing wells within even the first few years of production may provide significant economic benefits, especially during periods of downturns in oil and gas prices when drilling budgets are reduced"
George E. King, distinguished engineering adviser at Apache Corporation
American Oil & Gas Reporter magazine April 2015 edition. Excellent article!
"An analysis of 16 refractured Eagle Ford oil wells showed an average EUR increase of 57%, with the increase ranging from 10% to 184%" (see SPE 173340, presented at the 2015 Hydraulic Fracturing Technology Conference Feb. 2015) Excellent paper!
This series has generated substantial current knowledge about ReFracs! It strongly appears that today's process of refracing is developing to the point that it will be utilized much more often in the future regardless of the price environment!
Some of what we have learned
This and much more will be covered May 28th in Dallas, TX
"ReFrac Template to be utilized in calculating wells ReFrac cost & potential ROI"
"The ReFrac Risk window is narrowing substantially, radically, and quickly"
Operators reports addressed during the meeting are showing "ReFracs are adding 1.5 MMcfd to 6 MMcfd increase in production" "15 fold increase in production from a few wells that were about 5 years old" "Took a well from 50 Bopd to 650 Bopd (IP30)" "One 2010 vintage well had produced 4.8 Bcf and the refrac added 2.0 Bcf to its reserves"
"Expecting a 30% rate of return at current strip price from refracs"
"Calculating the cost and potential ROI of refracs is becoming clearer"
"Industry is moving toward agreement on a three-level refrac candidate well selection criteria"
"Clear relationship between low early hyperbolic decline rate & refrac success"
"There is a definite relationship between understanding root cause of poor initial performance and post-refrac production performance"
"Identification of technical factors that imply material improvement is possible"
"Identification of well-specific barriers that could disqualify a given re-frac candidate"
"ReFrac considerations: Physics, Geology, Engineering and Reservoir"
"ReFrac Options: What is already in the well?"
"Existing Well Configuration and effect on potential ReFrac"
"Current view on use of Diverters possibly along the entire wellbore" -
"Specifics of the various diversion processes"
"Zonal isolation issues and options"
"Reducing the cost of ReFrac jobs"
"Artificial Lift issues in horizontal wells"
"Impact of ReFrac operations on artificial lift"
"Which artificial lift technologies are applicable in various scenarios, and why?"
The Energy Forum (TEF) ReFrac Study© 2015
TEF ReFrac Study© 2015 report will be co-authored by Rocky Seale, Principle, Seale Enterprises Ltd. & Doug Walser, Technology Manager, Hydraulic Fracturing Center of Excellence, Pinnacle a Halliburton Co.
A complementary copy of the 2015 report will be available in July 2015 and provided to anyone who has attended one or more of the study meetings.
Our "Study of Restimulation (ReFrac) Practices" addresses some key questions about refracs at each meeting.
