Baffle Plates

Baffle plates are used to stop a rubber plug and indicate the position of the plug by an increase of pumping pressure. The plug landing at the plate indicates the end of displacement. Baffle plates are designed for ease of drill out. 

Fracturing Balls & Baffles

Fracturing balls & baffles are used to perform a multi-stage fracturing treatment. By pre-planning, fracturing baffles are positioned in the casing string prior to cementing. Starting from the bottom, successive intervals are perforated and isolated with fracturing balls which pass through the larger baffles above and seat on their specific baffle.

Cement Baskets

Cement baskets are used to prevent the movement of fluid into weak formations in the wellbore. Baskets are typically run above the weak formation. Canvas baskets are designed to dehydrate the cement to form a bridge at the basket. 

Casing Centralizers

Casing Centralizers are used to position tubulars in the center of the borehole allowing for proper stand-off during cement placement. Centralizers typically come in a spring bowed version and a rigid bow construction.

Float Collars

Float collars install directly into the tubular string being cemented and provide a check valve to flow into the tubular.  Float collars also provide a secure indicating stop for the wiper plug.  Float collars are generally run in combination with a float shoe to provide a back-up float arrangement.

Float Shoes

Guide equipment is attached to the bottom of the casing string to allow for the ease of running past ledges and wash-outs. Floats are used to reduce string weight and prevent the back flow of displaced fluids into the casing being cemented.

Guide Shoes

Guide shoes attach directly to bottom of the tubular being run into the well.  The open ended guide eases the tubular past ledges and wash-outs encountered in the wellbore.

Insert Float Valves

Insert float valve install into the tubular coupling and provide an economical version of a float collar or float shoe.

Miscellaneous Products

Many miscellaneous items are available as casing attachments and aids.  Mechanical wall scratchers are used to mechanically remove filter cake from the wellbore. Thread Lock is an economical method to securely join tubular coupling without welding.

Plugs - Bottom - Rubber

In certain mud drilling situations it is desirable to separate the lead cement from the drilling mud.  A bottom plug lands on the indicator stop and ruptures an internal disk which allows for the continued placement of cement slurry.  The top plug then lands and seats on the bottom plug. 

Plugs - Top - Rubber

Cement plugs are used to wipe the internal drift of the tubular being cemented. The plug also acts an indicator when stopped against a shoe, float collar, or insert float valve. All wiper plugs are composed of drillable materials.

Plugs - Top Wooden

Wooden plugs are used for the ease of drill-out. These plugs are mostly constructed of wood with rubber belting utilized as wipers. Wooden plugs are light duty and should only be used at shallow depths.

Plugs - Flex and Latch Down

Flex plugs are used in conjunction with fracturing baffles. Standard wiper plugs can not be used with fracturing baffles due to the internal diameter restrictions of the baffles. Latch down flex plugs can pass through certain casing restrictions and engage a latch down baffle sealing flow from both directions.

Auto Fill Assembly

Under certain conditions while installing the tubular into the wellbore it may be desirable to deactivate the floats temporarily. With the floats deactivated the tubular can fill with wellbore fluid.  The floats are then activated when desired by pumping rate or a mechanical device.

Formation Packer Shoes

An open hole completion involves installing the tubular string above the formation of interest. A formation packer shoe allows for guiding and a mechanically activated packer which isolates the cement from the open hole portion of the completion.

Multiple Stage Cement Collars

Multiple stage equipment allows for separate placement of cement slurries in the tubular string. Separate placement of cement allows for the reduction of hydrostatic pressure through-out the well bore and discreet placement of slurry when required.
