Casing Thread Connections Oilfield tubulars may have plain ends (no threads), API-specified threaded casing thread connections, or proprietary (non-API) threaded connections. API Casing Connections Oilfield casing conforming to API standards may be obtained with plain ends but ends are usually threaded and furnished with couplings such as: Except for Extreme-Line, male (or pin) threads are …
Casing pipes are robust and durable tubes made from different materials, such as steel or PVC, designed to provide structural support and protection to the wellbore or borehole. They are inserted into the drilled hole and cemented in place, forming a protective barrier that prevents the collapse of the well walls and the contamination of …
In order to understand the strengths of casing tubular material, it is important to understand the basic terminology and process of manufacture such materials to be able of accomplishing a successful casing design. Yield Strength In Casing Material The strength is the material property of steel which is usually indicated by its minimum yield strength or …
Introduction To Steel Casing Design Calculations From the earliest days of wells dug in the ground for various purposes, the need for some means of supporting the walls of the hole has been recognized. Many oil and gas wells of ancient times were lined or “cased” with rock. Over the years, the technology of casing …
The liner hanger system is installed at the top of the casing liner (One of Types Of Casing). The function of the liner hanger is to hang and suspend the liner. There are mechanical liner hanger and hydraulic set hangers. In this article, we will provide detailed steps for Liner Hanger Setting & Cementing Procedures. …
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, …
