Reservoir Performance & Production Optimization Consulting
Reservoir Surveillance, Performance Diagnostics, and Ranked Opportunity Screening — Turning Underperforming Wells and Reservoirs into Executable Recovery Plans — Worldwide
Assign your company's underperforming reservoirs and fields to A&A, and let the high-level, seasoned consultants of the A&A Consulting Team diagnose why actual production is falling short of potential — and build the ranked, economically justified plan to close that gap.
Avasthi & Associates, Inc. (A&A) is an independent petroleum engineering consulting firm, founded in 1990. A&A does not sell artificial-lift equipment, stimulation chemicals, injection hardware, or reservoir-simulation software — our only business is expert technical consulting, which means A&A's reservoir performance and production optimization recommendations are never influenced by a stake in any particular vendor or technology.
Most producing fields operate below their technical potential. Wells water out early, injection goes where it is not needed, drainage is uneven across the reservoir, and reserves get booked conservatively simply because performance is not fully understood. The high-level, seasoned consultants of the A&A Consulting Team have been diagnosing underperforming reservoirs, arresting production decline, and recovering reserves that others left behind since 1990 — onshore and offshore, in conventional and unconventional plays, around the world.
Is Your Reservoir Delivering Its Full Potential?
A&A's reservoir performance consultants are available to answer the questions that determine whether — and how — your field's production and recovery can be improved:
• Why actual production is running below forecast, and which causes are reversible
• Where the remaining reserves are, and which wells, patterns, or zones are not draining them
• What it will take — workovers, infill drilling, artificial-lift optimization, 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 it is worth
Reservoir Surveillance & Performance Diagnostics
A&A's reservoir performance engagements begin with an integrated diagnostic of production, pressure, water-cut, gas-oil ratio (GOR), and injection data, to establish where the reservoir stands today and why, including, but not limited to:
• Decline-curve and type-curve analysis: well- and field-level production-decline diagnostics, to separate normal depletion from reversible underperformance
• Material-balance analysis: using measured pressure and production data to estimate original hydrocarbons in place, drive mechanism, and remaining reserves, independent of a full simulation model
• Pressure-transient analysis: well-test interpretation to characterize near-wellbore skin/damage, effective permeability, and reservoir boundaries
• Pattern-level and injection-conformance review: comparing injection and production allocation, pattern by pattern, to identify thief zones, unswept areas, and voidage imbalance
• Water-cut and GOR trend diagnostics: distinguishing coning, channeling, and casing or completion failures from normal water/gas breakthrough
From Diagnosis to a Ranked Opportunity Inventory
A reservoir performance diagnostic is only useful if it leads to a ranked, actionable plan. A&A's consultants translate diagnostic findings into a prioritized inventory of production-optimization and recovery-improvement opportunities, drawing on the full depth of A&A's upstream practice:
1. 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.

2. Waterflood & Injection Optimization
Waterflood diagnostics, pattern balancing, voidage-replacement management, and sweep-efficiency enhancement, to correct the injection-conformance problems a reservoir-surveillance diagnostic identifies.

3. Recovery Improvement & EOR/IOR Screening
Screening, design, and evaluation of improved and enhanced oil recovery — from infill drilling and pattern realignment through CO₂, hydrocarbon-gas, nitrogen, chemical/polymer, and thermal EOR — to increase ultimate recovery beyond what primary and secondary depletion alone will deliver.

4. Integrated Reservoir Studies & Simulation/Modeling
Full-field static and dynamic reservoir modeling, history-matching, and forecasting-scenario analysis that quantify remaining reserves, rank development options, and support reserves booking, budgeting, and partner or regulatory review.

5. Field Redevelopment Planning
For mature and brownfield assets, a phased, executable redevelopment master plan that integrates the subsurface diagnosis with drilling, facilities, and economics — restoring production growth rather than managing decline.

How A&A's Reservoir Performance Engagements Work
Every A&A reservoir performance 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.
Software and Technical Tools
A&A's reservoir performance consultants are expert users of industry-standard diagnostic and modeling software, including, but not limited to:
• OFM and comparable production-data-management software, for decline-curve, type-curve, and pattern-level surveillance analysis
• MBAL, for material-balance analysis and drive-mechanism diagnosis
• Industry-standard well-test interpretation software (such as Saphir and PanSystem), for pressure-transient analysis
• ECLIPSE, IMEX, GEM, and tNavigator, for integrated static and dynamic reservoir-simulation studies
• Spreadsheet- and Python-based economic-evaluation tools, for ranking opportunities by incremental recovery and value
What A&A Delivers
A Reservoir Performance & Production Optimization 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 reservoir performance diagnostic report identifying why production is below forecast, and where the remaining, undrained reserves are
• A prioritized opportunity inventory, ranked by expected production increase, incremental recovery, and economic value
• Waterflood and injection-conformance diagnostics, with pattern-balancing recommendations
• An EOR/IOR screening recommendation, when tertiary recovery is technically and economically warranted
• A calibrated, integrated reservoir model your reserves booking and development decisions can stand on
• A phased, executable field-redevelopment plan for mature or brownfield assets
Frequently Asked Questions
How is Reservoir Performance & Production Optimization Consulting different from A&A's Production Optimization page?
Reservoir Performance & Production Optimization Consulting is the diagnostic entry point — the reservoir-surveillance and performance-diagnostic work that identifies why a field is underperforming and ranks the opportunities to fix it. A&A's dedicated Production Optimization page covers the execution depth of one of those opportunity types — well-by-well production-enhancement techniques such as fracturing, acidizing, sand control, coiled tubing, and artificial lift — once an opportunity has been identified and prioritized.
How does this service relate to Revitalizing Mature Oilfields?
Revitalizing Mature Oilfields describes A&A's three specific techniques for extending a mature or marginal field's productive life — bypassed-pay identification, fluid-recovery maximization, and waterflood redesign. Reservoir Performance & Production Optimization Consulting is the broader diagnostic and screening service that determines whether those techniques, or others such as artificial-lift optimization or EOR/IOR, are the right fit for your specific field.
Does A&A screen for EOR/IOR, or design and implement it?
Both, at different stages. This service's EOR/IOR screening determines whether a tertiary recovery method is technically and economically warranted for your reservoir, and which method looks most promising. Once a method is selected, A&A's dedicated EOR/IOR Consulting practice — covering waterflood optimization, CO₂, hydrocarbon-gas, nitrogen, chemical/polymer, and steam EOR, plus history-matching, pilot testing, and project operations — takes the project from design through full-field implementation and operations.
What data do we need to provide for a reservoir performance diagnostic?
A typical diagnostic starts with available production, pressure, water-cut, and GOR history by well or pattern; injection volumes and allocation, where applicable; and any existing reservoir or simulation models. A&A can often deliver meaningful diagnostic findings even from incomplete data sets, and will identify what additional data would materially improve the analysis.
Does A&A sell any equipment, software, or services beyond consulting?
No. A&A is an independent consulting firm with no affiliation to service companies, equipment vendors, or software suppliers — A&A's recommendations are driven solely by your asset's performance and economics, never by a stake in any particular vendor or technology.
Increase production, maximize recovery — start with a conversation.
