What is a packer oil and gas?
1. n. [Drilling] A device that can be run into a wellbore with a smaller initial outside diameter that then expands externally to seal the wellbore. Packers employ flexible, elastomeric elements that expand. The two most common forms are the production or test packer and the inflatable packer.
What is a cement retainer in the oilfield?
1. n. [Well Completions] An isolation tool set in the casing or liner that enables treatments to be applied to a lower interval while providing isolation from the annulus above. Cement retainers are typically used in cement squeeze or similar remedial treatments.
How does a cement retainer work?
The TAM Cement Retainer is inflated by circulating a ball to the tool. Pump pressure is then applied to inflate the element. The ball activates a sliding sleeve that traps the inflation pressure in the element. Additional pressure is then applied to expel the ball and ball choke through the tool.
What is bottom plug?
A bottom plug is a bridge or cement seal placed near the bottom of the well in order to shut it off. After the well is sunk to the required depth, the base of the well is plugged with concrete. This is called a bottom plug.
What is ERD packer?
PARVEEN Model ERD Retrievable Hydraulic Seal Bore Packer is a Retrievable Packer. Hydraulically set by pressure in the tubing. It is run with Hydraulic Setting Tool & retrieving is done independently from the Tubing, using a Retrieving Tool manipulated on a work string.
What is the difference between landing collar and float collar?
The landing collar can also be equipped with a ball seat, pinned to shear at approximately 1000 psi above the pressure required to set the liner hanger. The float equipment prevents the uncured cement in the annulus from flowing back into the liner.
What is centralizer in drilling?
Technical Summary. Centralizers are essential in drilling operations as it keeps the casing positioned in the center of the wellbore. Drilling Tools International carries a wide range of the single piece bow springs, hinged bow springs and solid body steel centralizers.
How is a well plugged and abandoned?
Cement is pumped into the well to cover and isolate the zones that produce oil and natural gas. When the plugging operation is complete, the workover rig moves o the location, the well head is removed and the associated flowlines are excavated.
What is top plug?
A top plug is a rubber seal in the casing string, which stops the fluid used in drilling from contaminating cement slurry. The top plug and the sack should be used to push the cement ahead and to prevent mixture with the mud.
What is packer mandrel?
Single Mandrel Packer Penetrators are one-piece products which transmit power through a single bore. They can accommodate a vast array of cable types and sizes, and are supplied factory-moulded to downhole cable (including the MLE if required) or via a Field Attachable connection.
How is CIBP used in the oil and gas industry?
It is highly dependable and widely used in the oil and gas industry. CIBP is used for well-abandonment, zonal isolation, stimulation, and casing pressure tests.
Can you drill out CIBP?
CIBP can be drilled out if necessary, maintaining sufficient strength while it’s set. It can be designed with shorter lengths to provide a shorter drill out time to save time and cost. It uses setting sleeves and adapter rods and can be set on wireline tool or pipe tubing.
What is a CIBP plug used for?
CIBP is used for well-abandonment, zonal isolation, stimulation, and casing pressure tests. It is available for tubing and casing sizes from 4″ to 20″ and is easy to drill out due to the cast iron material. The cast-iron bridge plug (CIBP) is considered as one of the most dependable and effective isolation plugs available.
What is CIBP removal technology?
The removal technology consists of a collection of thru-tubing fishing equipment (mills and motors), remedial or simulation equipment (composite bridge plug), and coiled tubing. The thru-tubing fishing equipment allows the CIBP to be drilled without pipe rotation.
