• Lead Geologist for a $380MM - 295Bcf EUR redevelopment project on a legacy onshore gas field with New Zealand’s largest Contingent Resource base. Focus on maintaining plant plateau of 90mmcf/day through end of license.
• Investigated and revised existing reservoir models for preliminary dynamic simulation – representing the first full-field history matched model for the asset. Gain insights on full field GIIP distribution, low-net.
• Delivered full field reservoir review (400m HC column) for brown-field asset to redefine legacy reservoir opportunities (un-swept gas) and highlight upside of low net pay intervals. Reservoir characterization and.
• Developed Integrated Reservoir Modelling Strategy for subsurface team to link modelling deliverables with key project decision milestones (drilling campaign phasing / development concepts) and Hydrocarbon Maturation.
• Redefined pay definition for fracture stimulation of upcoming 4 well drilling campaign. Integrated high resolution PEX, NMR pore distribution typing, petrography, OBMI, and PLT surveillance to increase expected.
• Integration of seismic interpretation (utilizing QI products and attribute analysis), conceptual geologic / facies models, and offset production / surveillance data to mature and rank subsurface drilling targets. Built.

New Plymouth, New Zealand

• Production geologist for the offshore Pohokura gas field in a joint-venture (JV) operating unit (OU)
• Investigated existing reservoir models and identified static parameters with the greatest impact on field behaviour (i.e. water flow). Recommended key updates to static reservoir model through collaboration and.
• Determined static reservoir model strategy for full field rebuild; assessing significance of subsurface uncertainties and determining how to effectively capture these ranges.
• Developed conceptual geologic models (depositional environment, reservoir characterization, structural framework, facies model) and developed implementation techniques for static model realizations.
• Delivered full set of static models (leading to a suite of history matched and forecasted dynamic models) culminating in a full probabilistic range of reserve outcomes and comprehensive documentation.
• Applied an integrated approach to reservoir modelling as a part of a subsurface asset team, using feedback cycles with dynamic testing to aid in decision making and streamline workflows.

Calgary, AB

• Play geologist for two consecutive unconventional shale gas Exploration Prospects.
• Lead role in play fairway mapping and risk segment designation for unconventional prospect. Using well log and core correlations, geochemical, mineralogical and production/test data from legacy and newly released.
• Responsible for defining subsurface reservoir inputs for probabilistic volumetric calculations. Verifying uncertainty ranges (P50, P90, P10) for reserves inputs.
• Operations Geologist role for two horizontal exploration wells (one including pilot hole with core). Geologic support for fraccing operations using log, core and cuttings data to analyse and predict frac quality.
• Planned appraisal well locations, incorporating 2D seismic data, to avoid potential drilling and production issues related to faults. Produced on-the-fly prognosis updates from 2D seismic data during real time drilling.

Calgary, AB

• Responsible for maturing and delivering a technical and commercial evaluation for a new unconventional resource play (shale gas).
• Initiated and refined basin screening criteria for mapping play fairway sweet spot.
• Produced regional risk segment maps determining prospect scale AOI based on geologic data (including reservoir facies, pay thickness, porosity/saturation, thermal maturity, resource richness (%TOC), mineralogy.
• Coordinated life cycle economic evaluation of AOI with multidisciplinary team (Drilling, Completions, Facilities, Land, Environment and Public Consultation) to determine commercial viability of prospective project.
• Delivered several significant investment proposals for senior management support of large land postings and purchases that were successful in growing a material and consolidated land position.

Calgary, AB

• Assessed fault seal potential throughout the gas fields of the Sable Offshore Energy Project (SOEP).
• 3D seismic interpretation to determine fault juxtaposition and calculate shale-gouge ratio (SGR) using offset well correlations.
• Volumetric assessment for potentially isolated gas accumulations.

St. John's, NL

• 3D seismic structural interpretation and conceptual geologic modelling of a secondary reservoir in the Hibernia Field, Jeanne d’Arc Basin.
