A Petrophysicist with over thirteen years of experience in domestic and international venues, from both operational and project perspectives. Specializing in the complete integration of core/core and core/log data, and correlation of near wellbore log evaluations with geologic models through “deterministic” and “probabalistic” means. Additional areas of focus include; 1/wireline and DST fluid recoveries and pressures to assist in fluid typing, reservoir continuity, and fluid contact depth determination, and 2/ electrical and acoustic borehole image interpretations to identify stratigraphic and textural changes within the reservoir that effect petrophysical parameters.

Technical Papers & Recent Projects:
1. The Hexdip Tool and Exploitation of Lake Erie Reservoirs, presented at the 1997 Ontario Petroleum Institute.
2. Comparison/examination of Borehole Imaging vs. Conventional Core, 1997 CSEG/SEPM symposium.
3. Determination of Porosity, saturation and fluid type – Bashaw Area “D2”, paper presented at the September 1993 Canadian Well Logging Society Sour Gas Workshop.
4. Basic Petroleum International Limited – Guatemala (22 wells) – Present
Responsible for providing geological and petrophysical analysis over a Lower Cenomanian carbonate reservoir. The lithology was predominantly dolomite with porosity and permeability enhanced from karstification and fracturing. The study involved the incorporation of core data for core/core, core/log regression correlations, determination of net pay summaries, average porosity and water saturation, and permeability index (Ki).
The petrophysical analysis formed the foundation for much of the geologic mapping of the reservoir. A better understanding of flow units, baffles and barriers within the pool, and a refinement in estimated OOIP was to be determined. This data was then incorporated into a flow simulation model to more effectively optimize the remaining reserves.
5. Gulfstream Resources – Sultanate of Oman (5 wells) – Present
Petrophysical analysis was completed on the Aptian carbonates of the Oman Group. The petrophysical focus was on porosity, water saturation, net pay determination, and identification of fluid interfaces. These low porosity limestones are texturally complex as evidenced by the large shifts in water saturation’s, and bulk volume water calculation’s (up to 75% Sw with little connate water produced on production tests). Cutoff parameters such as water saturation utilized in the estimation of net pay (in this particular case) was of little value.
6. PanCanadian Petroleum Limited – Countess “YY” Pool (35 wells) – December 1997
Responsible for providing petrophysical support to the geologic and engineering staff. The Countess “YY” Glauconite (dominantly quartz and chert) reservoir consists of 4 main facies, each facies possesses it’s own discreet porosity/permeability relationship, and flow unit character. Identification of facies from core and the recognition of core/log signatures was crucial to the project. Unique PHIE cutoffs ranging from 7% to 17% were used in the calculation of oil net pay, a constant PHIE cutoff for gas, independent of facies was also determined.
Significant factors which impact the efficiency of the waterflood were identified. Kvert/Kmax plots were completed and indicated two of the facies possessed vertical permeability barriers. Also, bitumen was present in most wells and adversely affected the flood efficiency in the specific areas of the pool, an incorporation of these permeability barriers when reservoir simulation is performed was recommended. In addition, the recognition of the short-comings of the core cleaning process (i.e. bitumen was removed resulting in erroneously high K values) initiated core measurement changes at PanCanadian Petroleum Limited.
7. PanCanadian Petroleum Limited – Lathom “A” Pool (34 wells) – September 1997
Responsible for providing petrophysical support to the geologic and engineering staff. The Lathom “A” Glauconite (dominantly quartz and chert) reservoir consists of multiple facies. Similar petrophysical analysis as performed at Countess “YY” was performed here. A major focus was the accurate determination of OOIP and OGIP. To this end, net pay maps determined from petrophysics were hand contoured, these maps included structure of the top and base of the facies so hydrocarbon typing was discerned. These maps were also cross-contoured with the net pay maps of other facies ensuring accuracy to inter-well thicknesses. Volumetric calculation for each facies gave a more accurate estimate of the placement of the hydrocarbons in the reservoir, resulting in focussed recommendations for pool optimization.
