Cement basket drilling consists of flexible steel spring bow welded to slip-on collars. Bows are hardened and tempered for maximum strength and uniformity. The cement basket is run on casing or
liners above weak or porous formations to provide protection from hydrostatic pressure generated by the cement column. The overlapping metal fins of the cement basket provide flexibility and fluid
passages while maintaining optimum support characteristics.
Performance Features of Cement Basket
The cement basket in drilling operation consists of heavy duty canvas liners and concentrated with high strength and flexible steel staves which are seated on the steel slip-on end collar.
Cement basket has the capability to help in premature cement hydration. This is to check hydro-static fluid column at the point of loss zone or weak formation
The cement baskets from Eneroil are designed particularly so that it can be able to adapt in a remarkable way as used in most of all types of well, to the bore hole and can hold large than the
nominal size of the holes.
These baskets are designed for installation between two stop collars. Hence, these does not meant to be reciprocated. But travels the length of the joint just to allow the pipe movement.
Options of Cement Basket
Cement basket is available from sizes 4½" to 30" sizes configurations.
Slip-on type and the hinged type cement basket can be normally installed between slip-on type stop collars or stop collar or hinged camp over the casing to hold them in a place.
The baskets can be rotated and reciprocated as per requirement.
