Casing Accessories
Whether drilling at shallow or extreme depths, the quality of our casing products will ensure the support needed for successful well completion. Working with our clients, we provide solutions to support casing installation in deeper, more challenging wells, and provide reliable performance under extreme conditions.
Built to withstand the rigors of high-pressure environments while maintaining well integrity, our casing accessories are designed to reduce downtime, improve operational efficiency, and help to ensure safe handling throughout the drilling process. All products manufactured by Sharpe® meet strict API and quality standards, enhancing safety and efficiency at the rig site.
Our range of Casing Accessories includes:
Sharpe® manufacture Casing Liner Hanger Systems that allow the intermediate casing string to be hung from the bottom of the surface casing.
The system runs a three-part system—Outer Landing Collar, Inner Casing Liner Hanger assembly, and Running Tool, that offers a simple latching mechanism designed to provide positive latching and ease of uncoupling when the string has been landed.
The Sharpe® Hanger System was designed for mine de-gasification applications but lends itself to customisation for various other applications.
With proven performance in the field, benefits of our Casing Liner Hanger System include:
- Available in multiple casing sizes, configurations and thread types
- Engineered to ensure maximum safety and operation
- Simple and reliable latching operation
- Torque through latching system for casing make-up
- Positive stop landing point
- Reduced costs through reduced production/intermediate casing string length
- Safety latch design to prevent accidental unlatching
A Casing Pup Joint is a short length of pipe (smaller than range 1 in length) with threaded ends used to make up a string of Casing to desired length from bottom of well to the Casing hanger in the wellhead.
Sharpe® Pup Joints are made to order, in accordance with API 5-CT, and can be tailored to customer specifications including:
- Outer diameter (OD) sizes
- Weights (standard or heavy wall)
- Grades including J-55, K55 and N-80
- Standard Lengths available in 2′, 3′, 4′, 6′, 10′, and 12′ lengths.
Casing and Tubing Crossovers enable the connection of two components with differing thread types or sizes as part of a casing or tubing string. Sharpe® specialise in the design, manufacture and licensed threading of Casing Crossovers from high grade steels that can withstand the demanding nature of drilling and completions.
Our Casing Crossovers can be made to suit a range of threaded casing diameters and can be finished with a corrosion resistant coating to reduce galling and wear during operation.
A Casing or Tubing Drift is a precision-machined cylinder that is pulled through casing, tubing or accessories to gauge and qualify proper internal clearance, ovality and straightness of the tube. Sharpe® can manufacture Casing Drifts in steel, aluminium, nylon or other non-metallic material in accordance with API 5-CT or to customer specification.
Sharpe® offers proprietary designs for a range of casing foot clamps specifically engineered for mineral exploration drilling rigs. These clamps effectively secure casing joints during installation. Our advanced foot clamp assemblies feature a hydraulic cylinder linkage bar that integrates seamlessly into the drilling rig table. The replaceable slip ramps are adaptable to various brazed clamp jaws, accommodating all standard casing and drill pipe OD sizes from 2-3/8 inches to 16 inches.
Each foot clamp is fully assembled, undergoes NDT (magnetic particle inspection of welds), and is certified by an RPEQ engineer. Additionally, all units are proof load tested to ensure they meet their designated Working Load Limit (W.L.L).
Our designs can be scaled or modified to fit specific drilling rigs or applications, and Sharpe® maintain a stock of critical spare parts for continued client support.
Sharpe® offer precision-engineered solutions for oil and gas well cementing. Designed and manufactured for reliability, our cement heads ensure efficient slurry pumping and cement plug release. We can manufacture Cement Heads in various sizes to match your casing and thread requirements, with pressure ratings to suit any operation.
Sharpe® manufactures and supplies an extensive range of Float Equipment, including Float Shoes, Float Collars and matching Top and Bottom Plugs. Choosing our equipment helps drive casing to depth more efficiently and improves cement quality.
Float shoes are engineered to attach to the bottom of a casing string and are equipped with a check valve (back pressure valve) to prevent the reverse flow of cement slurry from the annulus into the casing, as well as to block wellbore fluids from entering the casing string during installation.
The internal components of a float shoe are designed for easy drill-out if the well needs to be deepened beyond the casing point. Additionally, our single valve, non-rotating range significantly reduces drill-out time and enhancing operational efficiency. They ensure better control over wellbore pressures, minimise the risk of contamination, and improve the overall safety and reliability of drilling operations.
Sharpe® manufacture and keep stock of a range of Float Shoes, Float Collars and Top and Bottom Plugs in a range of sizes from 4.5” OD to 32” including stab in, burst disk and dual valve variants.
Landing Joints are specially designed casing joints attached to the casing hanger running tool, facilitating the lowering of the casing string and casing hanger into the wellhead. Sharpe® manufacture Landing Joints in all casing sizes, and can customise the length to meet specific client requirements.
Sharpe® manufactured Landing Joints help drilling operators ensure precise placement and secure installation of the casing hanger, enhancing well stability and integrity. Clients benefit from high-quality solutions that optimise wellhead operations, delivering efficient and reliable performance in demanding drilling environments.
Casing Centralizers are devices fitted with hinged collars and bow springs or Ridged fins help keep the casing or liner in the centre of the wellbore and ensure even placement of cement around the casing string. Stop Collars assist with holding the position of the Centralizer and limit movement. Together they work to provide uniform annular clearance, keep the casing from touching the side of the wellbore and reduce drag when running casing and assist to create a robust seal during cementing.
Sharpe® supply high strength centralizers and stop collars in a range of sizes from 4-1/2″ to 20″ to reduce corrosion and increase the lifespan of the casing.
Spinning Haul Plug / Nubbins are used for running and handling of casing joints and casing tools. They can be threaded to match that of the casing string. All Spinning Haul Plug are engineered, load tested and have certified lift ratings.
Flange Adapters are used to connect the casing string to the production well head and are manufactured to be either integral or welded designs.
Sharpe® manufacture Flange Adapters to suit all casing and flange combinations as per customer requirements.
Sharpe® stock a range of Casing and Tubing Couplings from 2-3/8″ to 13-3/8″ in grades J55, L80, N80 & P110.
