Four tools have been assembled into three sub-assemblies, "E-Z" Connector, Double Flapper Check Valve, and Hydraulic) SLICKLINE (In operation with Slick Line Confirming the well depth or clearance to perforations Running and pulling plugs or Low control devices Opening and closing sliding side-doors or similar completion equipment Conducting pressure and temperature surveys using mechanical or electrical Gauges and recorders, this we performed before each fracturing operation or stimulations Installing tubing pack-offs or similar completion devices Logging and perforating Valve Assemblies, Service Tools, Back Pressure Valves, Cameron Type ‘H’ Back-pressure Valve ), with respect to fracture stimulation fluids performing quality tests before each operation to have a good efficiency of the fluid. Including but not limited to: following the well program, modifying it as and if required, ensuring efficient personnel performance, assessing and finding appropriate solutions for any problems during operation, providing regular reports, interacting with any other services on the rig for more productive and efficient and desirable outcome. During this time I worked on the following rigs: • CEPCOLSA: HP Drilling , heavy oil and Gas • CEPCOLSA : Independence 34 Heavy Oil and Gas • BP: HP Drilling type of well heavy foamy oil • BP: PARKER, type of well oil. HPHT conditions. • BP:PRIDE , type of well – oil and Gas • PACIFIC RUBIALES: SAXON land rig, type of well, heavy oil. 12% H2S • PACIFIC RUBIALES: SAI land rig High Pressure. • HOCOL: PRIDE land rig , Horizontal • HUPECOL: SAI land rig type of well Oil and Gas • PETROMINERALES: Independence land rig High pressure 10.000 PSI in head • PETROBRAS: NABORS land rig type of well oil and gas. • ECOPETROL:PRIDE land rig

As Operator my responsibility was to do works of Cementing ( Squeeze, Casing 20", 13 3/8 , Liner 7", 5" Cementing High temperature, Cementing with Fiber, Cementing across of Coild Tubing and data acquisition ) Stimulation ( Acids HCL 5% and 28% , Frac-Acids) Fracturing ( Massive Fracturing to 15.000 PSI , Fracturing with Foam and Oil, Abrasic FRAC and Data acquisition ), Sand Control ( High Rate Water Pack , Horizontal Open Hole Gravel Pack , Single Gravel pack ), these jobs done with following equipment’s (RAM, Cementing Pumps, Blender, Hydration Unit FracPumps, SandKing, FracHead, and Frac-Van Monitoring data acquisition), and driver of heavy vehicle. As Field Supervisor my responsibility is supervising the day to day operation on the well of Stimulation, Fracturing, Sand Control, Cementing and Fluids). Including but not limited to: following the well program, modifying it as and if required, ensuring efficient personnel performance, assessing and finding appropriate solutions for any problems during operation, providing regular reports, interacting with any other services on the rig for more productive and efficient and desirable outcome. During this time I worked on the following rigs: • BP: HP Drilling type of well heavy foamy oil 17.000 Ft • BP: PARKER, type of well oil.
