From feasibility study to start‑up, run from Calgary

CHR provides project management, procurement, optimization and troubleshooting to the oil & gas industry. Our teams come from both sides of the work, design offices and fabrication shops, so designs get built the way they were drawn.

Equipment we engineer

Detailed specification, sizing, selection and design of vessels, including the internals for separation, oil treating and tower trays, as well as tanks, piping systems, compressors, pumps, exchangers and packaged skids and modules.

Oil facilities

Free-water knockouts, heater treaters and electrostatic desalters, plus retrofits of existing vessels to improve performance. Processing and storage, custody transfer, water disposal or injection for waterfloods, and the associated vapour recovery.
Gas & NGL processing

Separation, dehydration, dew point control, C2 to C6 fractionation, LPG or condensate recovery, and H₂S and CO₂ removal, including process modelling, simulation and design.
Compression

Reciprocating, rotary screw and centrifugal designs. Gas injection, with extensive experience in acid gas and CO₂ injection systems, well-site boosters and optimization of field gathering boosters.
Power generation

Power generation packages driven by natural gas or diesel reciprocating engines, or by natural gas turbines.
Pipelines & gathering

Well-site facilities and gathering systems, single-phase and multiphase, in sour and sweet service.
Packaged equipment
We specify, evaluate and buy skidded, housed and heated packages through long-standing relationships with packagers in Western Canada and abroad.

Our engineers

Our leadership spent decades in compression and process equipment fabrication shops before engineering whole facilities, and still checks every specification against how the equipment is actually built.
