WELL PLANNING GEOLOGIST

Skilled geophysicist/geoscientist with industry experience in Deepwater and Unconventional reservoirs. Expertise in quantitative interpretation (QI) techniques to gain a better understanding of rock and fluid properties within reservoirs, as well as providing seismic structure and stratigraphy maps and interpretations, and geological/geophysical analysis for well planning. Effectively communicate and collaborate across functions to execute concurrent projects with high levels of analysis and attention to detail, maximizing performance, minimizing risk, and achieving objectives on time and within budget. Core competencies include:

• Collaboration • Data Analysis • Risk Management • Problem Solving • Client Relationship and Project Management • QI Geophysics • Well log analysis/correlation and interpretation • 2D/3D/4D Seismic mapping and interpretation • Rock Physics • Data Science and Data Integration • Seismic well ties • Pre-stack AVO analysis/inversion and interpretation • Written and verbal communication • Reservoir Characterization • Geohazard assessment • Well Planning

EXPERIENCE

BHP; Houston, TX 09/2018 – 7/2021

Geophysicist II - Trinidad Exploration and Appraisal

Collaborated across two multidisciplinary teams to define and execute the geophysical scope of work for exploration, appraisal, well planning, and post well purposes to successfully meet teams’ objectives and ensure the results, limitations, and value of analysis were well understood.

Characterized untested amplitude anomalies, and provided better understanding of fluid/lithological affects, and ranges/uncertainty of seismic amplitudes and polarity in the overpressured oil window which was used in well planning and VRV (Volume, Risk, Value) analysis

Derived probability volumes of predicted lithology and fluid fill from seismic AVO attributes. These volumes were used to quantify the uncertainty in the lithology and fluid predictions and inform net to gross values away from well control in the geomodel.

Provided geophysical analysis for well placement, characterization of the overburden and identification of shallow hazards for well planning teams.

Oversaw all QI work with outside contractors in support of appraisal activities to ensure products delivered were at their technical limit, on time, and within budget

Interpreted and refined horizons in support of seismic net pay calculations for volumetric estimations

BHP Billiton; Houston, TX

Geophysicist II - Geophysical Business Support, 09/2015 – 09/2018

Provided Geophysical and QI support for Deepwater, Unconventional, and Mining assets that contributed to multiple Deepwater discoveries and improved understanding of unconventional assets.

Delivered a 4D seismic amplitude study in a producing field in the Gulf of Mexico that helped identify how production modified the oil water contact over time and detect new segments to drill.

Spearheaded a full QI analysis from rock physics to seismic inversion and characterization and interpretation of amplitude anomalies in the Exmouth Basin LJ85-LJ100 intervals which helped inform the decision on whether to exit the Basin.

Saved the company $100K to $200K per project by learning the workflow for running and interpreting both relative and absolute AVO seismic inversions internally. In addition to the savings, this led to more trust and efficiency in final products than if outsourced to a third-party provider.

Directly informed decisions related to allocating money/resources towards reprocessing and inversion projects by creating synthetic AVO models and feasibility studies to establish potential value and limits of data

Headed efforts to calibrate seismic amplitudes in both the Haynesville and Eagleford shale plays through comprehensive QI studies which established links between seismic and AVO attributes with engineering, petrophysical, and geological parameters.

Consulted and worked with coal mining asset during the processing and interpretation of their 3D seismic survey to ensure full potential of seismic data was realized.

BHP Billiton; Houston, TX

Geophysicist I - Eagleford: Production Unit, 07/2014 – 9/2015

Provided geophysical support and analysis to geologists and engineers for surveillance reviews, permitting, well planning and operations in the Blackhawk field.

Implemented a process improvement on the depth conversion workflow that contributed to an average landing accuracy of 8 feet and no Buda hits for wells drilled during my tenure.

Generated synthetic well ties across the field and used them to map key horizons and faults.

Extracted seismic attributes identifying highly fractured areas resulting in enhance porosity and lateral changes in rock properties.

Delivered shallow hazard assessments to the drill planning teams to ensure wells were not being drilled into faults or shallow gas charged zones.

BHP Billiton; Houston, TX

Graduate Geophysicist - Shenzi Field: Gulf of Mexico Production Unit, 07/2013 – 7/2014

Provided seismic interpretation of late Miocene and salt intervals, and opportunity generation and maturation of prospects in the Shenzi field. In addition to providing input and QC to seismic processing efforts

Seismic interpretations and structure maps received functional endorsement and were used to form the structural and stratigraphic framework of the geomodel.

Progressed a prospect to the point in which a recommendation could be made on drilling based on risk of reservoir presence, quality, and container boundaries using proven methods.

Baylor University; Waco, TX 07/2011 – 6/2013

Research Assistant

Operated and maintained a broadband seismic array which included collecting, processing, and updating a seismic database, along with computing P & S receiver functions for a project along the Gulf Coast of Texas.

Results from this work contributed to multiple publications for both me, other students, and professors

Samson Resources; Denver, CO 05/2012 - 08/2012

Geophysics Intern

Performed Reservoir characterization and developed a multivariate predictive statistical model to identify areas of enhanced productivity in the Middle Bakken and Upper Three Forks reservoirs through integration of multiple data types, primarily, extracted seismic attributes.

Work helped identify the sweet spots within the field.
