Reservoir Performance & Production Optimization Consulting

Avasthi & Associates, Inc. (A&A) helps oil and gas operators optimize reservoir performance, increase production rates, and maximize ultimate recovery from their fields. Since 1990, A&A Consulting Team has diagnosed underperforming reservoirs, arrested production decline, and recovered reserves that others left behind — onshore and offshore, in conventional and unconventional plays, around the world.

As an independent consulting firm, A&A has no equipment, products, or services to sell beyond honest engineering. Our only incentive is your recovery factor.

Is Your Reservoir Delivering Its Full Potential?

Most producing fields operate below their technical potential. Wells water out early, injection goes where it is not needed, drainage is uneven, and reserves are booked conservatively because performance is not fully understood. A&A Consulting Team's seasoned reservoir performance analysis consultants answer the questions that matter:

▪    Why is actual production below forecast — and which causes are reversible?

▪    Where are the remaining reserves, and which wells, patterns, or zones are not draining them?

▪    What will it take — workovers, infill drilling, artificial lift, injection realignment, or EOR/IOR — to increase production rates and ultimate recovery, and in what order?

▪    How much additional recovery is economically achievable, and what is it worth?

A&A Reservoir Performance & Production Optimization Consulting Services

Reservoir Surveillance & Performance Diagnostics

Integrated analysis of production, pressure, water-cut, GOR, and injection data — including decline-curve analysis, material balance, pressure-transient interpretation, and pattern-level conformance review — to establish where the reservoir stands today and why.

Production Optimization & Well Performance

Well-by-well opportunity screening: underperformer identification, artificial-lift evaluation and optimization, stimulation and workover candidate selection, and debottlenecking of wells and gathering systems to convert existing well stock into higher, sustained production rates.

Waterflood & Injection Optimization

Waterflood diagnostics, pattern balancing, voidage-replacement management, injection-conformance improvement, and sweep-efficiency enhancement — a core A&A Consulting Team specialty, led by principal-level waterflood operations and modeling consultants.

Recovery Improvement & EOR/IOR Screening

Screening, design, evaluation and optimization of improved and enhanced oil recovery — from infill drilling and pattern realignment through CO₂, gas-injection, polymer, cyclic steam stimulation (CSS), and steam flood EOR — to increase ultimate recovery beyond primary and secondary levels.

Integrated Reservoir Studies & Simulation/Modeling 

Full-field static and dynamic modeling, history matching, and forecasting scenarios that quantify remaining reserves, rank development options, and support reserves booking, budgeting, and partner or regulatory review.

Field Redevelopment Planning

For mature and brownfield assets: redevelopment master plans that integrate the subsurface diagnosis with drilling, facilities, and economics into a phased, executable program to restore production growth.

How A&A Consulting Team Works

Every A&A engagement is led by senior consultants of the A&A Consulting Team — typically with 20 to 40+ years of worldwide project experience — who perform the technical work themselves rather than delegating it to junior staff. Engagements are scoped to the decision at hand: a focused diagnostic review, a full-field integrated study, or resident advisory support to your asset team. Deliverables are practical and ranked by value: a prioritized opportunity inventory, not a report that sits on a shelf.

Why Operators Choose A&A

▪    Independent. No affiliation with service companies, vendors, or equipment suppliers — recommendations are driven solely by your asset's performance and economics.

▪    Senior-led. Principal-level reservoir/well engineers, geoscientists, and operations specialists on every project.

▪    Worldwide. Project experience across North and South America, Europe, the Middle East, Africa, the Caspian, and Asia-Pacific, in carbonate and clastic reservoirs, heavy and light oil, and unconventional plays.

▪    Proven since 1990. Thirty-six years of reservoir management, waterflood, and EOR/IOR consulting and training experience for operators, independents, investors, and government agencies.
