Premature setting of intermediate casing and drilling liners are a source of cost overruns for today’s drillers. Casing drilling allows you to drill and case the well simultaneously using standard oilfield casing that is permanently installed in the well. The technique can make drilling faster, safer and more cost efficient. It can also increase the depth at which casing is set, and perhaps eliminate one or more casing strings. Signa found this method very effective in South Texas to widen the window of pore pressure ranges in an open-hole section. Our engineers can explain the benefits to you, or provide a custom design for your program. Our step-by-step instructions include rig necessities, pressure profiles, directional plans, fluid program, scheduling, costs, cement, and surface equipment layout.
