Drilling Process Prepare the drill siteRigging up/moving the rig and related equipmentDrilling the surface holePump drilling mud/fluids Consists of water,

clay, special minerals and chemicals

Cools and lubricates the drill bit

CementingPortland cement Objectives To seal the annulus after a casing string has

been run To seal a lost circulation zone To set a plug in an existing well To plug a well for abandonment

Cementing Additives Fluid loss and gas migration additives Cement retarders (increases thickening time) Cement extenders(to decrease the density) Accelarators, Dispersants and other special

chemicals

Well CompletionMethod used is determined The characterstics of the reservoir Its economical potential

Methods Open-hole, perforated, tubingless

Drilling equipment is removedInstall the wellhead Seal off the well with safety valves and flow

control devices

Completion fluids Facilitates final operations before production Solids free Packer fluid inhibitors
