More experience 20 years in the oil and gas industry. I worked in top companies of the oil industry such as PDVSA, BP, Pacific Rubiales Energy, Halliburton, Pemex, Repsol YPF, Exgeo and Corpoven in positions of Wellsite Geologist, Reservoir Development Geologist and drilling Operations Geologist in the search y extraction of oil.
I have experience in:
-Well logs correlations and elaboration of estratigraphy-extructural cross sections.
-Elaboration of static and dynamic geological models of the reservoir (sedimentology, stratigraphy and structural geology).
-Elaboration of prognosis to drill wells.
-Experience in MWD/LWD measurement systems.
-Experience in entry point definition and geonavegation-geosteering
-Experience in well operations and perforation parameter.
-Elaboration of drill plan for directional wells (new horizontal wells, horizontal wells for re-entry, normal radios, multilateral wells, short radio with or without negative section, vertical wells and core taking.
-Experience in the taking special and conventional logs, in real Time and post wells perforation. Taking of pressure point.
-Log interpretation.
-Experience in the seismic rise area, making activities of supervisor of quality control in the obtaining of data in the field.
-Experience as geologist (EOR) optimizing recovery of oil from fields with active and inactive wells for maximum oil recovery, implementing changes in production methods, water or gas injection, addition of sand and changes completion.
-Experience in Workover area or Rehabilitation of active and inactive Wells. This area understands: Search of candidates wells for his rehabilitation or Workover. Addition of intervals for his cannon and fracturing. Isolation of not productive intervals, detours of obstructed wells by mechanical faults, cleaning wells.
In all my experience I have worked with composed lithology by shales, clays, consolidated and not consolidated sands, carbonates and limestones.
-Coordination and supervision work teams of mudlogging and directional companies.
-Experience in onshore and offshore drilling operations.
-Experience as gold mining exploration geologist coordinating exploration activities.

2006 – July 2006
Field supervision of seismic survey Sipororo 05K-3D
Supervision of technical, operative, environmental, health and safety control in Drilling of shot wells o Geophones field fits.
Statistical control overall project.
Geological evaluation of the deposits, through the elaboration of static and dynamic geological models of the same for their subsequent development. Preparation of maps (stratigraphic, sedimentological and structural) and stratigraphic and structural sections. Preparation of geological proposals to drill new and re-entry wells (short radio, medium radio, definition of optimal sites for drilling and direction of horizontal wells to be drilled. Preparation of directional navigation proposals for drilling new horizontal wells and re-entry (short radio, medium and multilateral radio), in the reservoirs.
Supervision of the logs run in real time and post drilling. Definition of stratigraphic tops. Operational monitoring of the drilling of horizontal and vertical wells in drilling rigs.
Search for candidate wells for rehabilitation (cleaning, change of production method, re-cannonade, opening of additional sands, re-fracturing and fracturing of additional sands, etc ...), including geological and reservoir analysis, and preparation of said proposals in formations with consolidated and unconsolidated sediments. Likewise, activities to update potential and custody of active wells and supervision on site.
Subject: Characterization of shales as a key tool to make quality control assuring during logging in “Oficina Formation, Distrito San Tomé”.
The study proportioned a report with filed maps that established a correlations of petrophysics parameter as a Density, permeability, vcl, etc., that should be used to adjust logging computations in future petrophysics studies or recalculations.
