Well Test Analysis (WTA) & Engineering Services began engineering and consulting services in November 2005. The principal, Jean Beriault is a professional Petroleum Engineer with 16 plus years of industry experience & knowledge, developed in the areas of AER well test compliance (related to the Well Test Capture system), well test analyses (PTA, RTA & DFIT/Mini-frac), determination of well performance & reservoir characterization & studies. Through her involvement in the successful Canadian industry Well Completion & Frac Database, she has significant knowledge of multi stage hydraulically fractured horizontal completions. Jean’s experiences in conventional and unconventional oil & gas reservoirs have taken her to numerous plays in the U.S., Australia, WCSB & South America.
Global Consulting services include the following:
- Pressure transient analysis (PTA – Build-ups, Falloffs, Draw-downs, DSTs) via conventional methods and simulation using Fekete software.
- Rate Transient Analysis (RTA) using Fekete software.
- DFITs/Minifrac/After-closure analysis using Fekete software.
- Determine reservoir pressure, oil well productivity, gas well AOF and deliverability, fluid flow characteristics / reservoir permeability, completion effectiveness and boundaries / anomalies via PTA.
- Determine reservoir characteristics, permeability, skin via RTA.
- Determine initial reservoir pressure, fracture closure pressure & gradient, instantaneous shut-in, leak-off, pore pressure, fluid efficiency, permeability & skin via DFIT analysis (Before & After Closure).
- Single and multi-shot acoustic well sounder (AWS) calculations and reports.
- Monitor pressure build-up / fall-off tests via diagnostic plots for sufficient PTA / DFIT analysis.
- Material balance and volumetric calculations (assess reservoir extent and limits before tie-in).
- Production forecasting.
- Critical rate calculations (minimum gas rates to lift liquids).
- Manage electronic (PAS file) submissions and compliance issues of well tests (related to the Well Test Capture system) and annual pressure surveys in Alberta.
