SUMMARY

Senior Reservoir Engineer with 15+ years’ experience in all aspects of Canadian oil and gas property evaluations including reserves, resources, economics, and risk. Expertise includes conventional and unconventional oil & gas, tight and shale oil & gas, horizontal multistage hydraulic fracturing, water flood, polymer flood, ASP flood, CO2 miscible gas flood, CHOPS, CSS, and SAGD.

Prepared independent reserves reports on 100+ WCSB properties, fields, and pools for 30+ public and private oil and gas companies including ARC Resources, Bonavista Energy, Caltex Resources, ConocoPhillips, Crescent Point, City of Medicine Hat, Encana, Harvest Operations, Imperial Oil, Pengrowth, Penn West, Gear, CNPC Canada, Daylight Energy and MEG Energy.

Audited and evaluated numerous EOR projects including major ongoing and potential ASP/polymer flooding properties such as Strathmore Lower Mannville B Pool, Wainwright B pool, Wildmere Lloyd and East Bodo Lloyd in Alberta, and Battrum Roseray and Cactus Lake Lloyd pools in Saskatchewan. Industry experience is complemented by 2 Master’s degrees related to EOR and heavy oil recovery, and 8 years’ experience as a university lecturer, researcher, and oilfield chemistry consultant. Ø Reserve Estimation Techniques: probabilistic and deterministic methods coupled with material balance, decline analysis, type curve generation, volumetric calculation, recovery factor forecasts, and reservoir simulation forecasts.

Ø Risk & Uncertainty Quantification: Monte Carlo analysis for probabilistic distributions. Ø Software Skills: Value Navigator, GLJ REM, GeoSCOUT, Mosaic, IHS AccuMap, PVR, MATLAB, Fekete FAST, Aspen HYSYS, Microsoft Office, and VERDAZO.

Ø Time Management: proven ability to manage multiple assignments concurrently and meet tight deadlines. Ø Strong interpersonal and communication skills: delivers high quality work independently and in multidisciplinary environments.

Ø Memberships: APEGA and SPE

PROFESSIONAL EXPERIENCE

Reservoir Engineering Consultant October 2017 – Present RWS Geomodeling Ltd. - Calgary, Alberta

Ø Marketing and coordinating Oil and Gas Engineering Consulting service in helping Clients with their A&D activities, reserve reporting, asset exploitation, development and management. Senior Reservoir Engineer February 2001 – May 2017 GLJ Petroleum Consultants Ltd. - Calgary, Alberta

Ø Performed independent reserve and resource estimations in alignment with Canadian National Instrument 51-101 and Security Commissions’ reporting requirements.

Ø Executed data analysis related to well testing, completions, PVTs, core analysis, daily operations & productions, logging, AFEs, companies' development plans and lease operating statements to get accurate inputs for reserve estimations, production forecasting, and economic assessment Ø Completed oral and written reports used for corporate year-end reporting to security committees, financial institutes and investors, A&D, exploration, regulatory submissions, litigation, and corporate advisory. Ø Conducted reservoir and production engineering studies to assist clients with valuing acquisition and divestiture opportunities. Example plays and pools include Deep Basin tight gas (Montney, Falher, Caddote, Bluesky, Cadomin, Spirit River, etc.), Bakken, Cardium, Viking, Clearwater, McMurray, Mannville, Wainwright, Belly River, and Gething. Ø Worked with a multi-disciplinary team to incorporate geophysical, petrophysical, and geological inputs into reserves quantification and production forecasting. HELEN H.
