WORK EXPERIENCE

Seismic Interpretation Specialist / Geophysicist – Pacific Rubiales Energy November, 2015 - Present

Description: Seismic processing and inversion results are key to the characterization of hydrocarbon reservoirs. Hence the QC of these

processes, as well as proper loading and integration of seismic data and well logs available, is important to maximize the reliability

of these results. The integration of all the available geoscience tools, in close collaboration with the interpreters, are key to improve

the characterization and the knowledge of reservoirs in order to find reserves in fields of exploration, and increase production in fields

mature. At this position, my final goal is to support the interpreters and provide them with tools to reduce uncertainty at the time to

propose new well locations.

Responsibilities: My responsibilities are provide specialized geological and geophysical knowledge in evaluating new

opportunities, regional studies, in areas exploration, and assets development; using seismic analysis for the identification of

options maturing prospects, modeling and generating velocity models/ QC seismic processing done by others, among others.

Actually, I am responsible for evaluating the seismic data processing 2D / 3D results done by contractors in the Colombian

Llanos Foothills; supervise the construction of velocity models, depth conversion, tying seismic with wells, as well as the

generation and analysis of seismic attributes. Withstand seismic interpretation and mapping of 2D and 3D structural systems.

Characterization and analysis of risk exploration prospects, identifying and evaluating new opportunities in exploration projects.

companies make better decisions, faster. This position reports to the VP of Technical Sales.

Responsibilities: Manage the key technical/solutions relationships in the world’s largest and most innovative E&P companies; team

with Territory Managers to create solution strategy and business plan ownership; develop domain expertise in analytics, geology, land

data, among others; provide upstream E&P and technical subject matter expertise in the business development process; provide

leadership within the technical team for mentorship, recruiting and career development; and complete DI Technical certification and

training on a regular basis.

Technical Services Consultant, Transform – DrillingInfo, Houston, TX April, 2013 – July, 2014

Description: I am responsible for technical consulting services identification and project delivery in Latin America, with a special

focus in Colombia. In addition, I have the opportunity to perform consulting services in support of customers with offices in Texas

and Oklahoma and potentially elsewhere; to supplement the level of Latin America consulting business. Projects needs the integration

of a wide-ranging of fields including analytic production optimization; wellbore interference analysis; microseismic interpretation;

well log analytics; seismic interpretation and seismic analytics; and seismic registration.

Responsibilities: Meeting with customers and potential customers, identifying specific customer challenges, proposing Transform-

based solutions, loading E&P data into Transform databases, performing the consulting services work required to fulfill project

Geophysicist, Noble Energy, Houston, TX May, 2009 – August, 2009

Project: Correlation of seismic amplitude anomalies to well logs and production in an oil field and surrounding prospects in the Gulf

of Mexico, resulting in reserve calculations and new prospect generation.

Description: Production analysis, evaluated petrophysical properties, generated structural and stratigraphic cross-sections and located

then on amplitude maps, generated RMS amplitude attribute maps and stratigraphic thickness maps, completed seismic interpretation,

Project: Correlation of velocity and well log measurements with pore pressure wellbore direct reading to predict pore pressure in

subsalt Gulf of Mexico reservoirs.

Description: Analyze the relationship between pore pressure and geological success in sub-salt wells, assembled a pore pressure

database containing all the wells in the Gulf of Mexico, created a workflow for generating geo-pressure attributes, and constructed a

EDUCATION

Master of Business Administration (MBA), La Universidad de Los Andes (Bogota, Colombia) August, 2015 - Current Expected graduation date: July, 2017

During the Master of Business Administration program I am developing leadership skills and strength knowledge of the functional areas of

management. The program offered by the Universidad de Los Andes School of Management is recognized among the top business schools in Latin

America for its academic excellence and standards.

Ph.D. Geophysics, The University of Oklahoma, Norman, Oklahoma Graduation: May, 2013

Thesis: Brittleness Estimation from Seismic Measurements in Unconventional Reservoirs: Application to the Barnett Shale (Advisor: Dr. Kurt

Marfurt)

Description: I evaluate two of the more popular brittleness estimation techniques and apply them to a Barnett Shale seismic survey in order

to estimate its geomechanical properties. Using specialized logging tools such as elemental capture tool, density, and P- and S-wave sonic logs

calibrated to previous core descriptions and laboratory measurements, I create a survey-specific BI template in Young's modulus versus

Poisson's ratio or alternatively λρ versus μρ space. I use this template to predict BI from elastic parameters computed from surface seismic

data, providing a continuous estimate of BI estimate in the Barnett Shale survey.

M.S. Geology, The University of Oklahoma, Norman, Oklahoma Graduated: Spring, 2009 Thesis: Quantitative Petrophysical Characterization of the Barnett Shale (Advisor: Dr. Roger Slatt)

Description: The purpose of this study is to identify which facies are more fracturable. A 3D reservoir facies model was built using

post-stack seismic data, acoustic impedance, and more than 250 wells and a detailed core description. The workflow proposed in this

thesis work allowed the identification of those facies with high gamma ray and high calcite content (high impedance) in order to

identify potentially most fracturable gamma ray parasequences in the Barnett Shale.

B.S. Geophysical Engineering, Universidad Simon Bolivar, Caracas, Venezuela Graduated: May, 2007

Thesis: Spectral Analysis of Seismic Data from Western of Gulf of Mexico

Description: 3D post-stack seismic data, well logs, and core interpretations were used to make a detailed seismic interpretation of a

structurally complex area in the Gulf of Mexico. Spectral decomposition results reveal an anomalous zone related to mass transport

deposits. Production data and petrophysical analysis indicated that not in all the cases the appearance of low frequency shadows, due

to loss of high frequencies, could be considered as direct hydrocarbon indicators.
