Well Production Optimization Analyzer
Diagnose well production decline and generate optimization recommendations
What You Can Do
You can analyze production performance data to distinguish between natural depletion, mechanical failures, formation damage, and flow restrictions. The skill guides you through structured diagnostic workflows that integrate production history, pressure readings, and well geometry data to pinpoint specific decline mechanisms and recommend targeted remedial actions such as acidizing, perforation optimization, or artificial lift adjustments.
Features
Analyze production trends using exponential, hyperbolic, and harmonic decline models to differentiate depletion-driven decline from mechanical issues
Apply pressure derivative diagnostics and type curve matching to identify wellbore storage, skin damage, and boundary effects driving underperformance
Evaluate damage severity and cleanup potential using flow efficiency calculations and skin factor interpretation
Systematically rule in/out equipment failure, scale buildup, paraffin deposits, and flow restrictions through structured questioning
Prioritize intervention candidates (acidizing, perforating, artificial lift optimization) based on production impact potential and cost-effectiveness
Compare actual well performance against type well and published type curves to benchmark decline rates and identify anomalies
Generate production forecasts and remaining reserves estimates based on identified decline mechanisms and recovery scenarios
Structure workover scope, success metrics, and post-intervention monitoring plans for remedial operations
Example Output
Example 1: Formation Damage Diagnosis
Input: 6-month production decline from 150 bbl/day to 110 bbl/day; pressure drop from 2,500 psia to 2,200 psia; well shut in for 2 weeks with pressure recovery to 2,350 psia
Output:
- Skin factor calculated at +4.2 (moderate formation damage)
- Decline curve shows hyperbolic pattern (not exponential depletion)
- Pressure transient analysis indicates near-wellbore permeability reduction
- Recommendation: Formation damage from mud invasion or scale. Acidizing candidate with estimated 40-60% production recovery potential. Cost-benefit favorable if acid cost <$15K.
Example 2: Mechanical Failure vs. Reservoir Depletion
Input: Production at 200 bbl/day for 18 months, then sharp 35% drop in 2 weeks; no pressure data change; well temperature normal
Output:
- Decline curve shows step change, not gradual hyperbolic decline (mechanical signature)
- Pressure readings stable (rules out pressure boundary/depletion)
- Likely causes ranked: tubing restriction (scale/paraffin), perforating erosion, or pump failure
- Recommendation: Run caliper log and production logging survey to confirm restriction location. If tubing-related, chemical treatment or mechanical cleaning. If perforation erosion, consider deeper zone perforation.
Example 3: Artificial Lift Optimization
Input: ESP-lifted well declining 8% monthly; subsurface pressure 1,800 psia; producing 95 bbl/day water-cut 65%
Output:
- Decline matches hydrostatic/skin model (not material depletion)
- Current pump insufficient for bottomhole pressure requirements
- VLP analysis shows pump undersized for fluid properties
- Recommendation: Upsize pump from 90 to 110 stages. Estimated production increase to 130+ bbl/day. Monitor pump intake pressure post-intervention.
