  Pacific Rubiales Energy

  Sept 2011 - Jun 2012

  Internship Trainee

  Among the different task I had to accomplish, there were:- To check quality of wells logs using commercial software packages (Interactive Petrophysics).- To collaborate in 4CR (Colombian Mines & Energy Ministry) forms elaboration.- To request and process logs header information and inventory from contractors.- To perform basic well logs interpretation in commercial software.- Collect and distribute information (hardcopies from logs, excel files inventory, general completion and drilling data from wells).- Help to update production surveillance databases (OFM software).

  GENESIS CONSULTORIA EN GEOLOGIA SAS

  Jun 2013 - Mar 2014

  Junior Petrophysicist

  - I helped characterizing the system of natural fractures in clastic rocks and we issued recommendations for better production of opened intervals in pay zones, integrating geological interpretations and wellbore image logs.- I applied multi-mineral models to evaluate mud-rocks and carbonate reservoirs located in Magdalena Basin (Colombia) reducing the high uncertainty in lithology and fluids quantification. (SEM-XRD and capillary pressure curves integration).- I contributed to the study of the geology-stratigraphy and properties of non-conventional reservoirs, particularly computing brittleness index and mapping “Fracturing trends" in Western Llanos Basin (Colombia).

  Pacific Rubiales Energy

  Apr 2014 - Aug 2016

  Petrophysicist

  - Interpreted around 150-200 wells drilled in Upper Magdalena Valley, Putumayo and Llanos Basins-Colombia, producing the main rock properties for reservoir static modelling.-Applied multivariate regression analysis, neural networks and other statistical tools to improve permeability predictions, calibrated against core data (RCAL and SCAL) reducing prediction errors by 20-50%. - Integrated NMR and dielectric logs to confirm oil saturations, hydrocarbon volumes and favorable mobility in overlooked pay zones.- Proposed (as multidisciplinary team) locations for water, polymer and surfactant injection projects in mature volatile oil/heavy oil fields.- Monitored well logging operations during 2014-2015 drilling campaign, producing quick-look interpretations during real-time operations, for completion purposes of appraisal and development wells. Logs interpreted included triple combo; special logs including dielectric, wellbore image, nuclear magnetic resonance, Cased hole (Cement evaluation), sampling and pressures.- Worked alongside commercial rock laboratories, to sample core plugs for routine and special core analysis, using well logs and core information. The work involved visiting the oilfield rigs to monitor coring operation and rock preservation, visiting labs to assure core quality and integrity and the correct implementation of procedures for reservoir characterization.

  AOS (American Oil Specialist) Consultores SAS

  Feb 2017 - Jun 2017

  Junior Petrophysicist

  - Evaluated around 100 oil wells drilled in Catatumbo Basin-Colombia including interpretation of lithology, rock properties, fluids information from an old suite of well logs and confirmed existing hydrocarbon volumes. - Performed environmental corrections, log edition and analyses using conventional petrophysics by aid of commercial software (Interactive Petrophysics) and curve edition tools. I collected information from old databases and contributed to the update of the geophysical model.- Proposed (as multidisciplinary team) new well locations for infill drilling in strategic areas of the main oil reservoirs.

  Texas A&M University

  Aug 2017 - May 2019

  MSc. student in Petroleum Engineering| Graduate Student Teaching Assistant

  • Performed petrophysics laboratory experiments for academic purposes including fluid density, viscosity and interfacial tension; Core porosity, permeability, fluid saturation, grain size distribution measurements, among others.• Taught and graded the laboratory section of the undergraduate course reservoir petrophysics to 40-60 students per semester. Both Routine (RCAL) and special (SCAL) core analyses, as well as fluid properties analyses were performed.• Published a conference and Journal Paper on a novel methodology to determine poro-elastic coefficient, pore volume and pore compressibility simultaneously from pulse pressure information, measured on shale rock samples using a core-holder. The work was patented. Show less

  PhD Student in Petroleum Engineering| Graduate Research Assistant

  • Developed an analytical proxy model for decline curve analysis and reserves forecasting, using MATLAB programming language resulting in a match between simulation and proxy model of +/- 10 %. (Unpublished).• Proposed a modified RTA methodology for bilinear flow of unconventional wells capturing conductivity losses during first days of production.• Proposed a modified RTA methodology to interpret linear flow of unconventional wells under stress dynamic permeability. (TBD)• Performed a simulation-based history matching study for a client in a volatile oil and gas condensate unconventional reservoir located in Vaca Muerta Formation (Neuquén-Argentina). (Unpublished).• Accomplished experimental work to test the capacity of a sorbent material to capture carbon from the atmosphere, achieving complete assembly of the core-holder, pressure transducers, DAQ system successfully; As a result, working capacity of the sorbent is around 8% (Unpublished).• Graded the undergraduate class reservoir petrophysics and the graduate class petroleum project evaluation and management including homework’s, quizzes, midterms and lab reports.
