ARC CBM Drill-In™ enhances CBM drilling fluids by
shutting down instantaneous imbibition into the low permeability
coal. This process mitigates phase trapping and optimizes
the reservoirs gas production potential. When used in CBM
drilling or cavitating fluids ARC CBM Drill-In™ controls
all multiple phase interfacial tensions between solids, liquids
and gases within the reservoir facilitating expedient cleat
clean-up by optimizing flow back of black water from the reservoir.
Typical increased clean-up rates of 20 – 40 % are in
direct proportion to the increased gas production volumes
observed on several hundred wells. When coal is drilled high
volumes coal fines are generated. Relieving these coal fines
of the hindrance generated by multiple phase interfacial tension
two key benefits are received. One is they do not pack as
a tightly bonded mass within the cleats. Secondly their resistance
to flow back when the well is produced is significantly reduced
facilitating rapid clean up of black water. Couple these features
to the added benefit of the Micro-solution traveling with
the drilling or cavitating fluid that enters into your reservoir
thereby mitigating phase trapping and overall reservoir performance
is optimized.
Introduction To CBM
Micro-solution Fluid Technologies
CBM
Micro-solution Technologies Control Multiple Phase Interfacial
Tension
CBM reservoirs are
highly susceptible to having their permeability to hydrocarbons
reduced when foreign fluids are introduced to them during
the drilling and cavitation processes. Significantly
better production performance is achieved when multiple
phase interfacial tensions between liquids, semi-solids
and solids within a remediating fluid and a reservoir
are minimized. By relieving the hindrance of multiple
phase interfacial tension the products penetrate faster
and further providing a better spend of the treating
additives. ARC CBM Regain™ provides multiple phase
interfacial tension reduction by more than 50 % between
all fluids, solids and semi-solids encountered as it
penetrates the reservoir. This translates into:
Improved Utility of Remediating
Fluids Through:
Faster Penetration
Deeper Penetration
More Efficient Spend
Enhanced Substrate and Black Water Release
From the Reservoir
Faster Clean-up Due To
Reduced Flow Back Pressures
A Regain of Production
as Ideal Permeability to Hydrocarbons is Reestablished
within the reservoir.
ARC CBM Foam Systems
ARC
CBM Foam Systems Offer Complete Package Solutions
ARC CBM Low Head D™
and ARC CBM Low Head C™ are combination packages
of a foamer and Micro-solution for the purpose of treating
coal or shale wells. The foamers also act as a corrosion
inhibitor. ARC CBM PCS™ is a foam stiffening enhancer
for use with the ARC CBM Low Head D™ product.
ARC CBM PCS™ also functions an environmentally
safe, chloride free coal stabilizing additive.
Coalbed Methane
(Field Trial)
ARC
Micro-solution Treated Wells Returned 50% More Gas
Coalbed methane wells in the Rocky Mountains were
stimulated with and without the addition of ARC CBM
Regain FMS™ Micro-solution product to the fracturing
fluid. The coal reservoir is at 3000 ft and 80 F.
The treated wells have a perm of 0.1 md on the average
with a net pay of 30 ft. The frac treatments consisted
of 36,000 gal of 70 quality nitrogen foam containing
20.0 ppt guar and 4.0 gpt foamer. The treatments contained
2 gpt ARC CBM Regain FMS™. 50,000 lb of 20/40
sand was placed at 20 bpm. The ARC CBM Regain FMS™
Micro-solution treated wells returned 50% more water
and produced 50% more gas on a cumulative basis over
six months.
Coalbed Methane
(Remediation)
ARC
Micro-solution Treatment Increased Gas From 1,500 to 4,000
MCFPM
The remediation of stimulation damage in a coalbed
methane well in San Juan Basin of New Mexico was accomplished
with a treatment of 30 gal of ARC Drill-In Micro-solution
product in 30 bbl of brine water. Gas improved from
1500 to 4000 MCFPM.
