Capabilities

Full-cycle production expertise.

Four integrated practices covering the value chain — from reservoir to sales.

Production Engineering

  • Artificial Lift (ESP, Gas Lift, Plunger Lift, Hydraulic, Mechanical)
  • Production Optimization & Bottleneck Identification
  • Well Interventions — candidate selection, execution & post-eval
  • Well Completions — design, optimization, services
  • Perforations (TCP) — design & execution
  • Production Facilities — energy source optimization
  • Well Stimulation — acid jobs & fracture design

Subsurface & Reservoir

  • Pressure Transient Analysis (PTA)
  • Rate Transient Analysis (RTA)
  • Reserves reporting under PRMS (P10 / P50 / P90)
  • Secondary Recovery — waterflooding sweep & efficiency
  • Vertical Flow Performance (VFP) curves
  • Numerical production simulation
  • Field Development Plans

Digital & Automation

  • HEYVA — field-wide underperformer detection
  • Data panels for well interventions
  • Multi-well database architecture
  • Third-party solution integration
  • Automated annular-space energy dissipation
  • Automated & optimized chemical injection

Strategy & Decarbonization

  • Business Development — rapid production-area assessments
  • Lifting cost analysis
  • Win-win commercial models for artificial-lift (ESP)
  • Methane quantification & flaring monitoring
  • Sales strategy for production regions
  • Technical proposals for digital-product market entry

Introducing

HEYVA.

Find every underperforming well.

A proprietary field-evaluation engine. Scan thousands of wells in minutes and surface the intervention or optimization that unlocks the next barrel.

Field-wide scan

See the whole field at a glance.

HEYVA ingests your production, pressure, and completion data and continuously benchmarks every well against its own potential.

Underperformer detection

The wells that are leaving barrels behind.

Automated ranking of underperformers with a clear diagnosis: lift issue, reservoir pressure, mechanical, or completion-related.

Intervention recommendations

From symptom to action.

Each candidate comes with a suggested intervention — stimulation, lift change, workover — sized for expected uplift and cost.

Optimization playbooks

Keep production at its optimum.

Continuous optimization advice for ESP, gas lift, and plunger lift systems, tuned to your field's operational envelope.

Uplift tracking

Prove every barrel gained.

Track post-intervention production against forecast and quantify the value delivered — per well, per pad, per field.
