I delivered the required documents in the last phase for the Quriyana 04 well: final drilling report, updated risk matrix with materialized events, consolidated archive of lessons learned, Well Integrity Format.

Executed the Quriyana 04 well in Putumayo, following ECOPETROL´s Well Delivery process methodology, I directed operational programs based on landmark tool simulations. I managed government documents like Forma 5 CR. I consolidated the lessons learned that materialized at the well.

realizo planeación para el cliente Ecopetrol, mediante la metodología "Well Delivery Process" para los campos Caribe, Churuyaco, Sucio, San Antonio en el Departamento de Putumayo y campo San Francisco en el Departamento de Huila, donde analizo los pozos de correlación, determino riesgos operativos, diseño estados mecánicos que mitiguen los problemas, genero los correspondientes estimados de tiempos y costos y se generan las bases de diseño.

Led planning for client Ecopetrol with methodology Well Delivery Process for the fields Caribe, Sucio, Churuyaco, San Antonio and San Francisco, reviewed offset wells, identified operational risks, designed the different mechanical status with their costs, time and Basis of design.

Led the planning of the drilling campaign of the Southeast field, Putumayo Basin, implementing new processes and engineering for continuous optimization. I Led workover operations. Developed and implemented the Well delivery process system for the drilling area. Standardized processes, policies, and procedures in search of the continuous improvement of KPIs

• Execution of drilling operations in Palagua & Acordionero Field, Drilling holes from surface to TD (4500-10000 ft) • Wells type J and type S.• Check out tools such as drilling motors, emitting sub, tool carrier and NMDC.• Consolidate lessons learnt• Perform drilling according to plan with different dog legs severities

• Execution of drilling operations in Rubiales Field, Drilling holes from surface to TD (4500-5000 ft)• Wells type J, Horizontal.• Check drilling programs and suggest changes• Identify ILT (Invisible Lost time) and NPT (Non productive time) and look for solutions• Participate at investigations to found root causes• Fill out the Ecopetrol documentation about Well Delivery process• Control Cost• Consolidate Lessons learnt• Performing field programs for relevant operations such as :o Drilling (Conventional strings, Mud Motors) for different hole diameterso Running and Cementing Casing and Linerso Wellbore cleanouto CBL-VDL logging o Drilling horizontal sections in sands (3-5 ft TST)o Fishing operations. o Issues of Rubiales Field (differential sticking, Stuck pipe, Incomplete running log)

• Planning and Execution of drilling operations in Castilla Field (Castilla – Castilla Norte), Drilling holes from surface to TD (7600-10000 ft)• Wells type J (low and high angle), Horizontal.• Check drilling programs and suggest changes• Identify ILT (Invisible Lost time) and NPT (Non productive time) and look for solutions• I was in charge of the execution of 5 rigs • Control Cost• Consolidate lessons learnt• Performing field programs for relevant operations such as :o Drilling (Conventional strings, Mud Motors, RSS (Power Drive, Geopilot) for different hole diameterso Running and Cementing Casing and Linerso Drilling without returnso Enlargement operations (While drilling)o Wellbore cleanouto Wellbore logging (Wireline, TDL and LWD) o Drilling horizontal sections in sands (7-20 ft TST)o Fishing operations. o Issues of Castilla Field (Mud losses, differential sticking, Stuck pipe).o Working 1500 HP Land Rig

• Planning of drilling operations in Cupiagua Field about 13 wells.• Comparing different alternatives of directional profiles for each well like re-entry or from surface. The objectives were to reach the Barco and Guadalupe Formations• Wells type J and Re-entry• The Costs AFE were around 25 MM US$ - 50 MM US$.

• Planning and Execution of drilling operations in Cupiagua Field, 1 well from surface and 5 re-entries.• Wells type J and type S, Re-entries from 14000-15000 ft to 17000 - 18500 ft• Check offset wells • Identify NPT (Non productive time) and look for solutions• Create AFE• Coordinate Operations and materials• Control Costs in the execution (The Costs were around 12 MM US$ for Re-entry and 49 MM US$ for the well from surface)• Performing drilling programs for relevant operations such as :o Drilling (Conventional strings, Mud Motors, RSS as Autotrack, Turbine) for different hole diameterso Directional drilling plano Whipstock Operations Re-entrieso Mud Strategy (Oil base mud and Water base mud)o Casing Designo Running and Cementing Casing and Linerso Wellbore cleanouto Wellbore logging (LWD, Wireline)o Fishing operations. o Issues of Cupiagua Field (Wellbore stability, differential sticking, Bit sticking)o Working 3000 HP land Rig

• Planning and Execution of drilling operations in the Exploratory group, drilling in different reservoirs of Colombia (Valle Inferior, Valle Medio and Valle Superior Magdalena, Catatumbo) • Wells type J and type S with different depths (Wells between 4000 ft and 16000 ft)• Check offset wells • Identify NPT (Non productive time) and look for solutions• Create AFE• Coordinate Operations and materials• Control Costs in the execution (The Costs were around 1.5 MM US$ - 23 MM US$)• Performing drilling programs for relevant operations such as :o Drilling (Conventional strings, Mud Motors, RSS as Autotrack – PowerDrive - Geopilot) for different hole diameterso Directional drilling plano Mud Strategy (Oil base mud and Water base mud)o Casing Designo Running and Cementing Casing and Linerso Wellbore cleanouto Wellbore logging (LWD, Wireline)o Fishing operations.
