JPP ENTERPRISES Model B Invertible Packer Tool Description Coiled tubing packers are available in a wide array of configurations. There are inflatable packers, hydraulic set packers, & mechanical packers. The model B invertible packer is a mechanical packer meaning hydraulic pressure is not used to set or anchor the packer. Tension or compression applied from the surface is used to set the packer -energize the element and ensure the packer will anchor and seal. The Model ‘B’ and Model ‘BL Invertible Packers are ideal for use on coiled tubing or conventional tubing in straight hole or deviated well applications, where the tubing rotation required to actuate the Packer is not possible. The Invertible Packer is set and released by simple set-down and pick-up motion of the tubing. It may be run as a Tension Packer or as a Compression Packer and can be set and released multiple times in one run. The Model ‘B’ and Model ‘BL’ Packer is also available on request with a "Sealed" Jay Mechanism (patented) for use in situations where poor well conditions might jam the Jay Mechanism. Applications Features: + Standard coiled tubing * collet type Slips with hardened edges interventions in oil, gas, and High Temperature Packing Elements injector wells © Multiple Configurations for the bottom + High Temperature (HT) operations connection - bull nose, drop out plug, pin requires specification of HT or box connection element «Has compatible Materials used © Sweet and sour service (#25) Benefits © High-strength construction makes the packer strong enough to hang weight below and withstand differential pressure during a coiled tubing treatment. Readily inverted so the packer can be set with compression or tension. Multiple sets can be achieved during a series of treatments within a wellbore corresion/ Acid resistant materials available Short compact design allows for deployment without extreme riser height Page 1 of 10JPP ENTERPRISES Operation: Tension Packer It is recommended that the Packer be run as a Tension Set tool on most well treating applications where the differential pressure from below is expected to exceed the pressure above the Packer. As a Tension Set tool in situations of reversed pressure differential, pressure above the Packer tends to release the Packer, or shear the shear screws, and must be offset by increased tension on the coiled tubing. (See "Effects of Pressure on Packers", page 2). Setting With the tool in the jayed (unset) position, run the tool approximately 1 foot below setting depth. Picking up on the coiled tubing will set the Packer (See "Setting Force Chart”, page 4). Each alternate set down and pick-up will frst release, then set the Packer. Releasing To release the Packer, simply set down approximately 1 foot below original setting depth. This will automatically re-jay the mechanism and lock the tool in the unset position for moving to another location or retrieving from the well. Safety Release If for any reason it is not possible to set down to release, or if the tool will not release normally, it is possible to retrieve the Packer by picking up and shearing the screws. (See “Shear Chart", page 4). This allows the Cone to drop away from the Slips and release the Packer. All parts are retrieved with the Packer. Compression Packer Where a Tension Set Packer cannot be used, such as the upper Packer in a coiled tubing hang-off or where the pressure above the Packer is expected to exceed the pressure below the Packer, the Model "B" Invertible Packer may be run as a Compression Set Packer by tuming the tool upside down and reversing the Top and Bottom Subs. Setting With the tool in the unset position, run the tool to the desired setting depth. Pick-up approximately 1 foot above setting depth and set down weight to set the Packer. Releasing Simply pick-up to unset the Packer, to retrieve, or to move to another location.

The first is the Packing Element and the second is the differential areas of the Packer Mandrel to the coiled tubing OD and ID areas. The first serves to set the Slips more as the differential pressure increases. As the pressure is applied across the set Packing Element, the Element is forced against the Cone which in turn is forced under the Slips. Since the Shear Screws are on the opposite side of the Packing Element, they are not loaded additionally by the differential pressure. The load on the Shear Screws will be either increased or decreased by the second factor of differential areas. The tubing pressure is felt on the area between the Mandrel OD and the tubing ID. The Annulus pressure is felt between the tubing OD and the Mandrel OD. Because the tubing OD and ID are so very close, as a reasonable average the net effect on the Shear Screws is the differential area between the Mandrel OD and the tubing ID multiplied by the differential pressure from the tubing to the annulus: F=Ax(Pr-Pa), where positive values for F are added to the forces to which the Shear Screws are being subjected. Positive forces are upward forces.

This condition will tend to unset the Packer or shear the shear screws. Pressure above the Packer can be offset by pulling additional upstrain on the coiled tubing, within the limits of the shear screws. The Area Chart on page 4 gives the maximum area affected by annulus pressure. To calculate the upstrain required to hold a differential from above: 1, Multiply the expected differential pressure by the area for the Packer size from the chart. AND 2. Add the setting force Note: Check to insure that this does not exceed the force for the number of shear screws run Page 3 of 10JPP ENTERPRISES ST EE —————E—EeEE———————— Effects of Pressure on Packers (cont.): Example: 2 1/8" Packer in 2 7/8" tubing on 1 1/4" coiled tubing. Annulus Pressure will be 1,500 psi greater than the tubing pressure. 1. Pressure Force 3.45 sq. inch x 1,500 psi = 5,175 Ibf 2. Setting force 3,000 Ibf Tension required at the packer = 8,175 Ibf. Note: Minimum number of screws required is 5 (for 9500 Ibf) The maximum pressure differential that the shear screws can support in this “reversed” setting method can similarly be calculated: P = shear screw force / area using the above example: 1. A= 3.45 sq. inch 2. shear screw force max 15,200 minus applied setting force 3,000 available force to shear screws = 12,200 P= 1220/3.45 = 3536 psi The middle chart on page 4 provides a quick reference based on the listed minimum setting force and the maximum shear screws being used. Compression Set The safety release feature of the Packer is not utilized when the Packer is set in ‘Compression. Therefore, a full set of shear screws should be installed when running the Packer as a Compression Packer. Annulus pressure greater than tubing pressure: This condition adds pack-off force to the tool and aids the tool operation. However, this condition tends to keep the Packer in the set position and makes releasing more difficult. Annulus to tubing differential pressure must be equalized prior to releasing. Tubing pressure greater than annulus pressure: Since the Packer has only one set of Slips, pressure from below the Packer will tend to unseat the Packer. Setting additional weight on the Packer will thus be required. The calulation for the weight required is the same as for a Tension Set Packer with “Annulus Pressure Greater Than Tubing Pressure.” (See page 2) Note: In operations where it is not possible to equalize pressure across the Packer by simply bleeding the higher pressure off prior to releasing the Packer, it is necessary to run an equalizing valve above the Packer. This can be a Dump Valve, Circulating Sub, or Unloader Valve. Care must be taken to ensure the valve's operation is compatible with the Packer operation.
