Setting Mechanisms for Types of Packer

Electric Wireline Set Packer

The electric line set packer is the most commonly used packer. It can be installed quickly and accurately at the required well depth. After setting the packer, you can RIH with the production seal assembly and production tubing. Once the seal assembly seals into the packer, space out the tubing string and continue completion operations.

Hydraulic Set Packer

There are instances when it is desirable to run an electric line set packer, however, well requirements may prevent using the such mechanism. A hydraulic setting tool may be used to accommodate the running of an electric wireline set packer. it simply takes the place of the wireline setting tool when circumstances so dictate. You can easily M/U & RIH with the packer equipped with the hydraulic setting tool on drill pipes. Once in depth, drop a ball through the string into its ball seat. by using mud pump, pressure activates the setting tool which will set the packer. Then POOH with the hydraulic setting tool and workstring and production seals and tubing is run to complete the well.

Some conditions which may require using a hydraulic setting tool are:

• If there is a previously set lower packer in place, the seals of the running packer will be required to be pushed into that packer using the workstring weight.
• If the weight of the packer and related tools and equipment is more than what electric wireline can handle.
• If the mud weight or viscosity is high and the packer can’t fall with his weight if run on electric wireline. The weight of the pipe may be required to push the packer down.
• As the inclination angle becomes greater, a point is reached where the packer will no longer fall down the well with his weight, which will require using a workstring.

Mechanical Set Packer

The mechanical retrievable packers are designed to be run and set on tubing, released, moved, and set again without tripping the tubing. They can be retrieved, redressed (if necessary), and used again and again. These packers are “ONE TRIP” packers.

There are several types of mechanical retrievable packers based on the tubing movement required to set the packer.

The internal latch type of mechanical retrievable packers is designed to be run on tubing and set by rotating the packer (approximately 1/4 right-hand turn) and then setting weight on the packer. Once set, tubing weight may be left on the packer or spaced out in tension or neutral. The release is accomplished by tubing weight down and right-hand rotation.

Applications for this packer include:

• Testing and zone stimulation
• Production
• Tubing anchor

The mechanical hook wall retrievable packer is designed with many of the same features as the previously mentioned latch packer. However, tension cannot be pulled against this packer. It is run and set on tubing, released, moved, and set again without tripping (pipe tripping) the tubing. They can be retrieved, redressed (if necessary), and used repeatedly.

This packer is normally used for:

• Wells where high differential pressures are anticipated from above and below the packer.
• Production
• Acidizing- hydrofracking, testing, swabbing, and other high-pressure well stimulation and production operations.
