The casing is mandatory in drilling operations as it has a lot of casing functions to prevent cave-in of unconsolidated formations, isolate problem zones, and many more. As mentioned before in our casing design guide, the selection of casing depends on many factors. Here in this article, we shall learn everything about the drilling best …
Take into your considerations: Installation Patterns (For Mechanical Cementing Aids) The selection of the proper installation pattern for mechanical cementing aids i.e. centralises, scratchers, turbolisers, etc. is essential to optimise casing running and cementing results. Cementing aids and their installation pattern are a function of operational conditions and cementing objectives. Because of these variable factors, …
Casing Check List Within a reasonable time prior to the beginning of the casing running operation, the Company Completion and Drilling Supervisor and the Drilling Contractor’s Tool pusher shall physically check the availability on the rig of all materials necessary to operations. Below we will provide you with the casing running checklist to help you …

Surface Handling Tripping Bit in Hole
As it is mentioned in Schlumberger Oilfield Glossary, PDC Bit is a drilling tool that uses polycrystalline diamond compact (PDC) cutters to shear rock with a continuous scraping motion. These cutters are synthetic diamond disks about 1/8 in. thick and about 1/2 to 1 in. in diameter. PDC bits are effective at drilling shale formations, …
