San Cristobal, Táchira. Venezuela
Cross-directional driller, focused on the execution and optimization of drilling projects in technically challenging environments. My experience includes the comprehensive management of onshore horizontal well operations, implementing innovative technologies (such as electromagnetic navigation (LWD) and telemetry (MWD) tools, downhole motors, and RSS systems). This includes reducing operational risks in unconventional reservoirs, always implementing QHSE procedures and techniques.
Professional Challenges Overcome
Navigation in complex geological formations: drilling direction in unconventional reservoirs (e.g., shale and tight sands) with a high risk of collapse and differential sticking, maintaining the planned trajectory with a margin of error of less than 1%.
Operational crisis management: handling critical events such as lost circulation, differential and mechanical sticking with the use of hydraulic hammers, following QHSE safety procedures and protocols, avoiding loss of productive time.
Adapting to international regulations: compliance with HSE and environmental standards on multinational projects.
Personal achievements
Technical innovation: Optimizing drilling times, adapting drilling techniques in soft formations using parameters (RPM, weight, flow rate, and differential pressure), reducing drilling time and improving the trajectory while avoiding high DLS.
Leadership in multicultural teams: Junior engineer training in directional drilling and continuous pulse telemetry techniques, including the installation of digital and analog sensors, as well as the use of data acquisition and parameter monitoring software.
Key Skills
Interpretation of 2D/3D trajectory plots and collision avoidance.
Electromagnetic and gamma ray logging systems (LWD) and continuous pulse telemetry (MWD).
Real-time data analysis and machine learning applied to failure prediction.
Horizontal, multilateral, and Geo steering drilling in complex reservoirs.
