Wmega Technologies Inc. TSR Installation, Usage & Repair

The Final Solution To Your Challenges (Tubing Saver Rotator, Patent Pending)

INSTALLATION

The TSR is one unit installed during a pulling job (see drawing). The Rig will have a pin end sticking up and a pin end sticking down on the TSR Tubing Mandrel. The Rig should:

1. Make up the bottom pin end to the Tubing.

2. Lower the Mandrel and Bowl into the wellhead until it seats on shoulder within wellhead.

3. Pack off wellhead with normal rubber and plate (2-7/8” or 3-1/2”).

4. Attach the Swivel (one can leave on Pump Tee on future pulls).

5. Make up the Pump Tee.

6. Install 8’ or longer pony rod immediately above pump (longer than stroke length). Add or remove another pony rod above pump on future pulls. This may move wear pattern up and down the hole to previously unworn tubing.

Installation Points to Consider:

· The 2-3/8” TSR (TSR2000) and 2-7/8” TSR (TSR 2500) both use the standard 2-7/8 rubber and top plate to seal the wellhead off.

· The 3-1/2” TSR (TSR3000) uses the standard 3-1/2” rubber and top plate to seal the wellhead off.

· The TSR replaces the wellhead bowl, slips, and bottom plate halves.

· Installing a pony rod immediately above the pump will normally change the wear pattern from the rod boxes to areas previously unworn. Thus, extending the life of the tubulars.

· If a tubing anchor is to be used, then one needs to purchase a “Downhole Swivel” to be placed above the anchor, or a “Rotating Tubing Anchor”. These are available from several companies. Normal installation with one type of swivel would involve (a) setting down the bowl within 1 inch of the wellhead lip (or one could set down all the weight on wellhead), (b) set anchor by rotating to the right, (c) shearing pin within downhole swivel, (d) releasing anchor will tension pull when ready to pull out of hole. Other swivels have left hand release, etc. Once the swivel is set to turn (shearing pins), then one could turn the tubing when desired.

USEAGE

The Mandrel is designed to be stronger than J-55 tubing while maintaining a Rockwell Hardness of C22 or lower (To minimize H2S stress cracking). Different metallurgy may be available for high strength or severe corrosive situations. The TSR is designed to be turned easily with one person using a pipe wrench. The pumper or treater procedure may:

1. Insure Safe Operation when turning rotator by inspecting area and using proper safety precautions.

2. Grab hold of the bottom part of the swivel or on the tubing mandrel.

3. Rotate the Tubing Clockwise. Then pump chemical inhibitors (if applicable)

4. A “Pointer” is made up on the swivel or mandrel to guide rotation of the TSR. Commonly, this pointer is rotated relative to a laminated “Pointer Card” that a person could carry. One Part of the Round Card has an area to point at the Pumping Unit. Months or Numbers are then marked on the card to show relative position at which the pointer should be set on after rotation. If the Date were January, then the “Pointer” on the swivel or mandrel would be pointing at the Pumping Unit, while April would have the pointer aligned about 240^o clockwise from the Pumping Unit (the eight o’ clock position).

5. Once a person turns a few wells, then they will know where to turn the “Pointer” on the Swivel without rechecking the Card or an operator may prefer to have the person rotate ¼ turn every time.

6. This Pointer Card method allows one to check to see if the rotator is being turned by anyone with a card (supervision check).

7. If the wellhead leaks, then the operator can tighten down the dognut or replace the rubber element without a rig (normal operation).

It is recommended to have the tubing rotated immediately before doing a batch chemical treatment down the casing. This will allow inhibitor to coat the clean area that was previously wiped off due to wear from rods or rod guides. If the tubing is rotated after a batch job, then part of the tubing will not have an inhibitor film (not recommended). The automatic rotators (which cost about 300 % more than the TSR) wipe off inhibitor over 100% of the circumference and therefore do not benefit failures due to corrosion holes like manual rotation may. Thus, automatic rotation costs more and may have less benefit in wells in which corrosion inhibitors are being used.

REPAIR

Repair of the TSR mandrel assembly is easily accomplished if ever needed. There are three O-Rings in the TSR Bowl assembly. The top two O-Rings can be changed by one person removing the Bowl Plate and inserting new O-Rings. The bottom O-Ring will require a rig to pull the TSR from the well as will replacement of the thrust bearing. Failure of the O-Rings is not critical and may only allow fluids to enter into the bearing housing area and thereby lead to future corrosion of some of the elements (Bearing, bowl, and mandrel). However, O-Ring failure normally should not immediately hurt the rotation of the tubing or allow fluids to exit the wellhead since the wellhead fluids are usually sealed with the top rubber element. When the tubing is to be pulled, one should inspect the rotator for any potential repairs. The TSR consists of only (a) a machined bowl, (b) a machined tubing mandrel, (c) a machined bowl plate and hex screws, (d) 3 O–rings (available off the shelf), and (e) a cylindrical thrust bearing (available off the shelf). Thus, this TSR is designed to use off the shelf items available at hardware stores, supply companies, and/or from Omega Technologies Inc., which makes in-house repair easy to do (if necessary). In addition, this TSR normally replaces only the bowl and bottom plate halves of an existing wellhead, thus the rubber and top plates and dognuts are available as standard equipment at an oilfield supply store.
