CALLIOPE GAS RECOVERY SYSTEM
| Calliope is a new generation of fluid
lift technology that achieves substantially
lower flowing bottom-hole pressure than
conventional production methods because
it does not rely on reservoir pressure
to lift liquids. Calliope has proven
to be effective, particularly in wells
below 10,000 feet, when all other fluid
lift technologies have failed. |
CALLIOPE'S DISTINGUISHING FEATURES
- Does not depend on bottom-hole pressure
to lift liquids
- Only one down-hole moving part
- Simultaneous flow reversal in two
wellbore chambers
|
CALLIOPE IS NOT GAS LIFT OR GAS CIRCULATION
- Overcomes gas lift's and gas
circulation's dependence
on bottom-hole pressure
- Overcomes the complex down-hole
valve arrays and small i.d. limitations
of gas lift

ACTUAL FIELD RESULTS FROM OWNED AND OPERATED
WELLS
- Achieved production rates of over
600 Mcf per day on previously dead
wells with average production rate
of 270 Mcf per day (top 10% of
U.S. onshore wells)
- Reserve addition cost of $0.50 per
Mcf, or less
- Added .58 to 2.2 Bcf of proved developed
reserves on previously dead or
uneconomic wells given-up on by other operators
- Lowered abandonment pressure to less
than 100 psi at 8,500 feet
- Lifted liquids from depths of 8,200
to 18,400 feet
- Effective in wells with packers and
restrictions as small as 1-7/8ths inches
- Extremely well choreographed and
tightly planned; veteran implementation

CALLIOPE CREATES PROFIT AT LOW RISK
- Highly predictable production rates
and reserves
- Finding cost under $0.50 per Mcf
- 90% economic success rate
- Low sunk costs; compressor and
other tangible equipment represent
over 50% of total
system costs
- Excellent risk-adjusted economics
including immediate cash flow, quick
payouts and excellent
return on capital employed (ROCE)
- Defers liabilities, saves leases
and prevents waste

OPERATING FEATURES
- Does not rely on bottom-hole pressure
- Only one down-hole moving part (a
standing valve)
- Simultaneous flow reversal in two
wellbore chambers
- Very effective in deep wells
- Effective in wells with packers and
small restrictions
- Compressed gas used to lift liquid
is isolated from the formation
- Liquid is separated from the gas
phase at or below the perforations
- Gas flows up the casing annulus (the
super highway) where friction is minimal;
liquid is lifted up a separate interior chamber
- Gas Management Platform uses standard
oilfield components
- System is energized by a conventional
oilfield compressor
- Telemetry can monitor and control
the System

PRINCIPLE OPERATING BENEFITS
- Creates minimum flowing bottom-hole
pressure
- Outperforms other technologies thereby
expanding the drainage area
in reservoirs where multiple wells are competing for reserves
- Tolerant of fines and eliminates
paraffin problems
- Operates effectively in deep well
environments
- Facilitates chemical treatment of
the formation and tubulars
- No tubular wear, stalled plungers
or gas locking
- Prevents waste
