We are a Calgary, Alberta based energy consulting company that combines a balance of rigor and simplicity in our work.
Reservoir Engineering
PDL has extensive North American & International conventional & unconventional reservoir engineering experience. We focus on understanding behavior before embarking on advanced production analysis or simulation. Bob is developing new evaluation techniques to forecast production and estimate in-situ stress changes from depletion.
Well Completion Design
PDL works with operators to achieve staged-success in more challenging environments. Stages of success may include pilot/execution, technical, and commercialization phases. Kirby helped design the longest horizontal well that could be hydraulically fractured using a ball-drop/open-hole packer system in a west-central-Alberta tight sandstone reservoir.
Production Engineering
We use our reservoir & completions engineering experience to optimize brownfield natural gas & oil fields. Kirby increased gas production by >25% from >2000 commingled, group-metered shallow gas wells using engineered well servicing programs and systematic data collection to optimize the frequency of periodic clean-outs of groups of wells.
Well Test Design, Execution, Supervision & Analysis
We provide a turn-key service from conception through execution and analysis for many types of specialized well testing including: Flow & Build-ups, Injection/Fall-off, Interference Testing, Production Logging & DFITs/DFIT-Flowback. The best test results are achieved with clear objectives, integrated planning, oversight and analysis. Robert recently planned and supervised a DFIT Flow-back test executed on DST tools in a vertical well to test in-situ stress for possible hydrogen storage.
Hydraulic Fracturing Design, Diagnostics & Optimization
PDL offers an integrated hydraulic fracturing diagnostic service that combines DFITs, frac stage pressure fall-off analysis & offset well pressure data (Fracture Driven Interactions) to quantify fracture heights, lengths, perforation cluster-efficiency & static fracture conductivity. We have applied this workflow successfully in several Montney, Duvernay, Permian & Marcellus pad horizontal settings so far.
Helium, Geothermal, CO2 Injection, Disposal, Storage
Our range of experience is leading us into some interesting new projects. We are proud to bring experience from our long history in petroleum engineering to these new energy transition applications.
