A WEALTH OF EXPERIENCE
Obsidian Engineering brings over 150 years of project experience ranging from large diameter pipelines to gas processing plants and transmission compression installations. We are able to assemble a team fronted by experienced personnel for any project scope while maintaining a lean structure with low overhead.


GAS PROCESSING FACILITIES
M2 GAS PLANT
$65 MILLION TIC
Green field gas plant with a rated inlet capacity of 100 MMscfd. Equipment installed
included propane refrigeration, condensate stabilization, NGL storage, compression,
inlet separation and utility system.
D1 GAS PLANT
$65 MILLION TIC
Greenfield gas plant with a rated capacity of 100 MMscfd. Equipment installed included inlet
compression, propane refrigeration, sales compression and NGL storage.
EDSON GAS PLANT
$60 MILLION TIC
Expansion project to increase both capacity and liquids recovery. Process included liquid
recovery (de-ethanizer, stabilizer), lean oil absorber, 3000HP refrigeration compression.
All process and utility heat provided by a steam heating system.
SIMONETTE REFRIG. EXPANSION
$55 MILLION TIC
Brownfield 100 MMscfd sweet gas plant expansion to an existing sour gas processing plant.
Installed equipment primarily included engine-driven propane refrigeration package and
utility heat package.
DOE CREEK 13-24 COMPRESSOR ADDITION
LEUCROTTA EXPLORATION: $7.5 MILLION TIC
Inlet expansion consisting of 3-phase separation and 2370 HP engine driven compression.
J-T plant assessment included review of the impact of higher temperature feed gas vs. previous
operation involving a blended inlet (compression and high-pressure inlet pipelines).
Optimized J-T plant operating parameters considering the associated increase in liquid rates
and higher stabilizer overheads flow to maintain target sales hydrocarbon dewpoint.
COMPRESSION FACILITIES
MULTIPLE COMPRESSOR STATIONS
$20 MILLION TIC
Various compressor stations, designed for 6 to 12 MMscfd (2 stage units, up to 1500HP-Waukesha
7042’s). Stations were pre-fabricated and modularized, flexible to be easily duplicated and moved if
necessary. Stations included a single inlet separator, single compressor (2-stage), single dehy unit, flare
stack & office building. Design accommodated spacing requirements for AB, BC & SK.
COLUMBIA 15-36 COMPRESSOR STATION
$35 MILLION TIC
Greenfield 60MMscfd (designed for future expansion to 120 MMscfd) Compressor Station and Refrige
Plant located in Columbia field of Alberta. Consisted of Inlet Separation, de-ethanizer, de-butanizer, inlet
compression (2 x Caterpillar 3612LE – 30 MMscfd ea.), refridge compression (1 x Caterpillar 3512 TALE),
sales compression (1 x Waukesha L7044GSI – 60 MMscfd), condensate pumps, liquid storage tanks, VRU,
flare equipment and office building.
KAYBOB COMPRESSOR STATION
$55 MILLION TIC
DESIGNED COMPRESSION HP: 10,000 HP (RECIPROCATING)
Greenfield compressor station with a design throughput of 40 MMscfd, expandable to 80 MMscfd and
with provisions for a low pressure/booster inlet. Facility design included condensate handling considering
a design ratio of 200 bbl/MMscf. Installed compression equipment included Waukesha L7042 and P9390
engine-driven package.
GAS TRASMISSION EXPANSION (TURBINES)
$90 MILLION TIC
DESIGNED COMPRESSION HP: >22,000 HP (TURBINES)
Brownfield compressor station expansion involving the installation of two Solar T70 turbine-driven
centrifugal compressor sets with rated capacity of 292 MMscfd each.
