Follow up drilling oil producers and water injection horizontals and verticals wells. Tops defining stratigraphic, correlation wells, sampling coordination channel, run conventional and special logs in real time and post drilling, taking pressures point, defining entry point, navigation producing section horizontal wells , directional paths monitoring while drilling horizontal wells, optimum zone definition section while drilling horizontal wells producing, coordinating and supervising work teams mudlogging and directional companies.
Used Tool: Office.

Well correlation, geologic revision and modification of structural, Isópac maps, litophaci and elaboration of geologic sections of the deposits of the Coastal assets of PEMEX.
Types of lithology worked: Shales. Limestones, Dolomites, Marls, Sandstone
Used tool: Lanmark Apllications (Geography Discovery).

Definition of prospectic areas for the perforation of new locations with holes turned a side in formation with consolidated sediments. Elaboration of geologic proposals for the new perforation of locations, which includes elaboration of structural, Isopac maps: Of total net sand (ANT) and petroliferous net sand (ANP) and of pressures. Analysis of its directional trajectories. Geologic-operational pursuit and supervision in site to the off the track well perforation type “S”.
Update official maps of the deposits.
Search and analysis of candidates for rehabilitating wells (add and insulation ranges, fracturing and changing production method) in formations with consolidated sediments and carbonates.
Supervision in the preparation and final revision of the structural and ANT (ANP) Isópac maps for project reserves calculation made by company contractor for submission of reservations.
Supervision to the Bullfight electrical - nuclear logs and definition of estratigraphys ceilings.
Definition depth for pressure point and monitoring in the decision-making.
Stratigraphic and structural cross sections.
Types of lithology worked: Shales. Limestones, Sandstones, clays, coal.
Used tools: Lanmark Apllications (Openwork: Stratwork, Siswork).

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.
Used tools: Office.

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.
Used tools: Lanmark applications (Geographix Discovery), Geoframe, OFM, Aico, Centinela.

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.
