BASIC COMPLETION METHODS Well Completion and Stimulation 3 GEOPET INTRODUCTION Once the design well depth is reached the formation is tested and evaluated. To complete the production well PLATFORM casing is installed and cemented and the drilling rig is dismantled. SEA BED A service rig is brought in to 30 CASING 20 CASING perforate the production casing 13 3 8 CASING and run production tubing along 7 LINER Production casing 9 5 8 with downhole equipments. Production begins after surface safety equipment installation RESERVOIR inished. Well Completion and Stimulation 4 GEOPET WHAT IS COMPLETION Well completion creates a dependable pathway to the surface for the hydrocarbons. The term completion describes the assembly of downhole tubulars and other safety equipments that is required to enable the safe and efficient production of oil or gas from the well after it has been drilled. Well Completion and Stimulation 5 GEOPET BASIC WELL COMPLETION TECHNOLOGY Each drilled wellbore awaiting completion is unique. Even nearby wells drilled to the same reservoir can have differencies in depths formation characteristics and hole sizes A wide variety of equipment designs and procedures have been developed to provide safe efficient conduits from subsurface reservoirs to the surface in different situations. The ideal completion design minimizes initial completion and operating costs providing for the most profitable operation of an oil or gas well over its entire life. Well Completion and Stimulation 6 GEOPET TYPE OF COMPLETION Natural Completions Natural completions are those in which little or no stimulation is required for production. Sandstone and carbonate systems .
