|
This term refers to the amount of slackoff weight or tension that is left on the packer when the tree is landed and the wellhead is flanged up.
|
Landing condition

|
Installing casing to the casing set point.
|
Land casing
|
|
The process of assembling flanged components such as pressure-control equipment.
|
Flange up
|
|
In well completion this is the action of finish an operation or process.
|
Flange up
|
|
This effect is caused by pressure changes inside the annulus and tubing at the packer, acting on different areas.
|
Piston effect
|
|
Tubing strings tend to made this effect only when the internal tubing pressure (pi) is greater than the annulus pressure (po).
|
Buckling
|
|
This is simply a mechanical means of forming a seal between two strings of pipe or between the pipe and the open hole. This generated seal isolates the tubing from the casing or open hole, preventing vertical flow of fluids or gases.
|
Packer
|
|
This packer element have teeth that anchor the packer in the casing or open hole.
|
Slips
|
|
This packer element support the slips and create a wedge to enhance anchoring capability

|
This packer element expand to seal the area between the packer and the casing or open hole
|
Elastomer element or Packing element
|
|
This packer element maintains a consistent bore and typically has an ID compatiblewith the tubular used. Outer body components are supported by the mandrel
|
Mandrel
|
|
This packer element initiates the setting sequence when desired during installation.
|
Setting mechanism
|
|
This packers do not have releasing mechanisms and are not retrievable from surface. In these the tubing can be removed from the well without releasing the packer. Permanent packers can only be removed by destroying their integrity through milling or drilling.
|
Permanent packer
|
|
These packers are in integral part of the tubing string. The packer is set, released and pulled with the tubing string.
|
Retrievable packer
|
|
These packers are designed to meet general or specific well conditions and provide a long operational life in those conditions. They are manufactured from a variety of materials to meet operational life expectancy in different environments.
|
Production packer
|
|
These packers are used to perform specialized functions, these are commonly used to pressure test casing and repair if a leak exists; temporarily suspend producing intervals; and protect the casing string from high pressures during hydraulic fracturing.
|
Service packer
|
|
In this packer set application, tubing movement is used to create the force necessary to set the packer and energize the element
|
Mechanical set
|
|
In this packer set application, force is generated internally within the packer by applying fluid pressure to set the slips and energize the element.
|
Hydraulic set
|
|
In this packer set application, an electric pressure setting tool is used. An electric current ignites a powder charge to create a gas pressure within the setting tool. The gas pressure then acts on a hydraulic piston to create a force sufficient to set the packer slips, energize the element and shear the setting tool from the packer.
|
Wireline set
|
|
This effect is the result of pressure changes, which occur inside the tubing string and annulus at the packer. The result of this effect is either an up or down force at the packer.
|
Piston effect
|
|
A device in a length of pipe that allows some pipe length expansion or contraction.
|
Expansion joint
|
|
In this effect the hydrostatic pressure in the well acts on the end area of the tubing string. This creates an upward pressure-related effect, resulting in a reduction in the weight of the tubing string as well as a shortening of the overall length of the tubing string. How is known this effect?
|
Buoyancy
|
|
This eefect will occur due to two different force distributions. One is the compressive force mechanically applied to the end of the tubing, and the other is the internal pressure that results in a force distribution on the ID area of the tubing
|
Buckling
|
|
This tubing effect will occur when the pressure inside a tubing string is greater than the pressure outside the tubing and also fo the compressive force applied to the end of the tubing.
|
Buckling
|
|
This is defined as tubing that is bowed from its original straight condition. The tubing will bow outward until it contacts the casing wall at which point it will begin to coil.
|
Buckled tubing
|
|
A tubing will buckle or bow outward until it contacts the casing wall at which point it will begin to coil. How is referred this coiling of the tubing?
|
Corkscrewing
|
|
Above this point in the tubing, buckling does not occur. How is known this point.
|
Neutral point
|
|
This effect occurs when pressure is applied to the inside of a tubing string: The pressure differential creates forces within the tubing string, which are trying to burst the tubing. The burst forces created within the tubing string due to the differential pressure causes the tubing to swell.
|
Balloning
|
|
In this effect exists a pressure differential on the outside of the tubing string, then the force created is attempting to collapse the tubing.As the tubing tries to collapse, it lengthens if it is free to move. How is known this effect?
|
Reverse ballooning.
|
|
This is a continuous length of steel tubing with no joints. In general, this is fabricated to the length needed for a particular well application and rolled onto a reel for transport to a well site for placement in the well.
