In the demanding world of oil and gas exploration and production, specialized tools are required to handle the extreme conditions and materials encountered. One such tool, essential for working with high-alloy (hard) casing, is the button slip.
What is a Button Slip?
A button slip is a type of slip used in the oil and gas industry to secure and release casing strings during drilling and production operations. Unlike traditional slips, which are designed for standard casing, button slips are specifically engineered for high-alloy casing, often referred to as hard casing. This type of casing is made from materials like stainless steel or chrome-molybdenum alloys, offering exceptional strength and resistance to corrosion.
Why Use a Button Slip for Hard Casing?
High-alloy casing, while robust, presents unique challenges for traditional slips:
