HaloFrac charges are designed and qualified to create an ideal perforation for hydraulic fracture stimulation in conventional and unconventional reservoirs. The proprietary technologies in HaloFrac incorporate DynaEnergetics’ latest advances in liner materials and shaped charge geometry. Extensive modeling and testing has been conducted on a variety of low and high permeability rock samples in our Section IV laboratory. This iterative process has resulted in a shaped charge with superior frac performance across a wide range of formations.
Halofrac charges create a clean and open tunnel and provide clear access to tunnel tip fractures. Liner material (light colored material around the tunnel tip in the rock section image below, creating the appearance of a halo) penetrates into the shale core, initiating fractures that lower frac breakdown pressures. This improves the operating efficiency of hydraulic fracturing services.
Highly symmetrical and uniform fractures are generated around the wellbore casing and within the target reservoir when perforating with HaloFrac. The well is connected to more reservoir and total estimated ultimate recovery is maximized.
OPTIMAL WELL PRODUCTIVITY AND FRAC PERFORMANCE IN UNCONVENTIONAL RESERVOIRS
– Higher initial production;
– Higher productivity ratios;
– Lower breakdown pressures result from tunnel tip fractures;
– Reduced treating pressures and increased treating rate;
– Reduced bridging and screenouts during fracture treatment;
– Uniform proppant placement across the perforations;
– Uniform distribution of treating fluid and pressure across the perforations;
– Faster ramp up to treating pressure.

STANDARD DP SHAPED CHARGE
With conventional shaped charge technology (diagram upper right) casing entry hole size variation leads to non-uniform frac clusters. This frequently results in inadequate access to the upper portion of the pay zone and reduced production potential.
HaloFrac shaped charges lower the risk of non-productive clusters and stages. Uniform casing entry holes ensure the designed treatment pressure, fluid flow and proppant density is achieved at each perforation within the stage. This creates the greatest certainty that frac clusters will form as designed and well production is optimized.
HaloFrac charges deliver “better”, more uniform fracs, require less “horsepower” and achieve higher fracture stimulation efficiencies. Every perforation contributes to production and delivers higher initial production and sustains those levels for longer. HaloFrac shaped charges enable optimum EUR at the lowest possible total cost of completion.
Case Study
BACKGROUND/CHALLENGE
– Offset well was perforated with competitors equal/uniform EHD shaped charges at 6spf, 60deg & 3guns/stage, 35 stages in total
– Both wells have the same completion design and are assumed to be directly comparable to each other.
– Wells in general area have frac gradient >0.84psi/ft.
ACTUAL STIMULATION RESULTS
– Treating pressures on average 8.1% lower per stage (~640psi);
– Reduced pump time by 64 min;
– Reduced HP requirement by as much as 5.1%;
– 100% of stages frac’d successfully (35 of 35).
ACTUAL PRODUCTION RESULTS / 231 DAYS TOTAL TIME MONITORED
Average increase in Oil Production of ~35 bbl/day compared to offset well
– Total increase of 8150 bbl produced in 231 days
– Total increase of $407,500 in Revenue at $50/bbl
Average increase in Gas Production of ~45 mcf/day compared to offset well
– Total increase of 10.350 mcf produced more in 231 days
– Total increase of $31,800 in revenue at $3,075/mcf
RETURN ON INVESTMENT – ACTUAL AND PROJECTED
7-1/2 Month Production Return on Initial Investment (ROII):
– Increase of $407,500 in revenue at $50/bbl;
– Investment of 630 HaloFrac Shaped Charges at $18* incremental cost =$ 11,340 per well;
– 3593% ROII per well.
Projected ROI assuming an average 85% well decline in 3 years for the Bakken:
– Potential total increase of ~38K bbl produced in 3 years;
– ~$1.9M in additional revenue at $50/bbl.
