CO2 Huff-and-Puff Consulting
Cyclic CO₂ Injection Design and Optimization for Conventional, Tight Oil, and Shale Reservoirs — Worldwide
Assign your company's CO₂ huff-and-puff project — from candidate screening through cycle design and field-wide optimization — to A&A, and let the seasoned consultants of the A&A Consulting Team put more than forty years of hands-on CO₂ injection experience to work for you.
Avasthi & Associates, Inc. (A&A) is an independent petroleum engineering consulting firm. A&A does not sell CO₂, injection equipment, or reservoir-simulation software — our only business is expert technical consulting, which means our CO₂ huff-and-puff design and optimization recommendations are never influenced by a stake in any particular vendor or technology.
The seasoned consultants of the A&A Consulting Team have been working on CO₂ huff-and-puff projects since the early 1980s, and are available to help your company with all aspects of designing and optimizing CO₂ huff-and-puff projects, in conventional and unconventional (tight oil and shale) formations, around the world.
CO₂ huff-and-puff — also known as cyclic CO₂ injection or CO₂ soak — is a single-well stimulation technique in which CO₂ is injected into a producing well, allowed to soak in the reservoir for a period of time to mix with and mobilize the oil, and then produced back from that same well. Because it does not require establishing an injector-producer pattern across the reservoir, huff-and-puff is often the most practical enhanced-recovery option in tight oil and shale formations, where poor inter-well connectivity and low matrix permeability make conventional flooding impractical.
A&A's CO₂ Huff-and-Puff Consulting Services
A&A Consulting Team's extensive experience working on CO₂ huff-and-puff projects includes, but is not limited to:
• Conducting state-of-the-art CO₂ huff-and-puff simulation and optimization studies, using industry-standard software
• Optimizing CO₂ huff-and-puff cycles — injection volume, soak time, and production periods
• Optimizing cycle efficiency to enhance production rates and reduce breakthrough risk
• Evaluating CO₂ injection and soaking periods to maximize oil recovery
• Analyzing reservoir heterogeneity and CO₂-matrix interactions to improve sweep efficiency
• Addressing challenges specific to tight oil and shale formations, such as diffusion-dominated recovery, gas-breakthrough control, and production-decline mitigation
• Designing and evaluating pilot and full-field CO₂ huff-and-puff implementations
• Conducting history-matching and sensitivity analyses to improve CO₂ efficiency
• Conducting economic feasibility studies and optimizing injection strategies
What A&A Delivers
A CO₂ huff-and-puff consulting engagement with the A&A Consulting Team is built around the practical decisions your company needs to make, including, but not limited to:
• A candidate-well and candidate-field screening study, ranked by estimated huff-and-puff potential
• A recommended cycle design — injection volume, soak time, and production strategy — supported by reservoir simulation and history-matching
• Pilot-test design and a field-wide implementation plan, with monitoring recommendations to track cycle performance and manage gas breakthrough
• Economic evaluation and sensitivity analysis to support the investment decision
• Presentation-ready recommendations for your company's management, partners, and investors
