Production engineering, digital solutions, and HEYVA field intelligence for oil & gas operators worldwide.
Consulting Services
Four integrated practices covering the value chain — from reservoir to sales.
Introducing
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.
HEYVA ingests your production, pressure, and completion data and continuously benchmarks every well against its own potential.
Automated ranking of underperformers with a clear diagnosis: lift issue, reservoir pressure, mechanical, or completion-related.
Each candidate comes with a suggested intervention — stimulation, lift change, workover — sized for expected uplift and cost.
Continuous optimization advice for ESP, gas lift, and plunger lift systems, tuned to your field's operational envelope.
Track post-intervention production against forecast and quantify the value delivered — per well, per pad, per field.
HEYVA ingests your production, pressure, and completion data and continuously benchmarks every well against its own potential.
Purpose-built engineering tools and analytical software designed by Cor4 Digital to optimize field production, artificial lift, and drilling operations.
Real-time quantification and analytical validation of true incremental oil gain post-intervention against baseline DCA decline curves.
Interactive visualization and diagnostics for well production tests, transient pressure build-ups (PTA), and nodal IPR/VFP performance curves.
Continuous monitoring and rheology optimization for drilling mud density, viscosity (PV/YP), and solids separation efficiency in shaker units.
Predictive Arps hyperbolic decline curve analysis and machine-learning forecasts for multi-well field production streams.
Intelligent scheduling, candidate ranking, and Gantt sequence optimization for workover, stimulation, and rig fleet operations.
24/7 surveillance of electrical parameters, motor temperature, intake pressure, and drive frequency for electric submersible pumping systems.
Pressure vs. True Vertical Depth (TVD) gradient calculation and fluid contact detection (GOC/WOC) across static and flowing surveys.
Next-generation energy software, automated chemical injection controls, and AI optimization modules currently in active engineering.
