Description
IMPROVED TRU-TAG TAGBAR
Concept:
The Tru-Tag tagbar concept is the ability to use in any way, a device that will determine, aid or assist in the ability to determine the proper alignment of the rotor to the stator of a Progressive Cavity pump with using a locating device that indicates the depth of measurement by means of weight gain/loss, regardless of where it is placed in the wellbore throughout the tubular string. The design of the Tru-Tag system is intended to be used below the Progressive Cavity pump but is not restricted in concept and design to be adapted anywhere throughout the tubular string in the future.
Design:
The "Tru-Tag" tagbar is designed for the purpose of measuring the exact placement of the Progressive Cavity pump rotor in the stator once ran in a wellbore.
The Tru-Tag tagbar is a two piece device, the first part is what is called the "Mandrel body" (5) and the second part is called the "Locating device" or "Locking device"

Design:
The "Tru-Tag" tagbar is designed for the purpose of measuring the exact placement of the Progressive Cavity pump rotor in the stator once ran in a wellbore.
The Tru-Tag tagbar is a two piece device, the first part is what is called the "Mandrel body" (5) and the second part is called the "Locating device" or "Locking device"
(2).
The Tru-Tag tagbar Locating device or Locking device (2) is attached by means of welding/threading/or any other form of adhesion to the rotor with the ability of being able to pass through the stator with ease and not damaging the stator or any part of the tubular string. The Tru-Tag tagbar Locating device (2) will pass into the Mandrel body (5) that will be threaded/welded/ or any other means of attachment thus stopping the rotor (13) from passing through the stator (14). The Locator device (2) will now rest in the Locator device seat (6) (also referred to as the Locking device seat). This function will also ensure that the rotor may never be lost in the well bore through the tagbar even if the rod string is parted or rotor is broken.
Now with the Locating device (2) inserted into the Mandrel body (5) the rod string can be hoisted up to determine the rod string weight alone. The Locator key (10) will hold the indicator up to 3-4 daN over string against the Locator key recess (1), before being released and pulling free with the use of the Bellville washer (12) resistance. Prior to pulling free it will be measured on the rod string from once the average rod string weight started to gain and now an exact measure will be known where the rotor (13) lays from inside the stator (14).
Fluids and solids will be able to pass into or out of the Mandrel body (5) through the By-Pass ports (4) and hollow Locating device seat (6), thus allowing for circulation out the bottom of the tubular string.
The "Tru-Tag" tagbar will have full flow, as not to impede the flow of fluids and/or solids into/out of the stator. Will be balanced on the Progressive Cavity pump as not to affect the performance of the pump or cause any wear to any part of the rod and tubular string.
The Titus Tru-tag was designed because of the indecisive techniques that a rotor was spaced out properly in a Progressive cavity pump. Other devices utilize only the weight of the rod string and rotor to stop moving through the stator to indicate that the rotor is sitting on a tagging system and then a guess of the exact rod weight and rotor placement into the stator was then taken. The problem with using this method is not being sure that the rotor is travelling all the way down to the tagging system and possibly stopping prior to there and giving a false measurement of where the tagging system really is located. The advantage of the Tru-Tag system is that it will lock in the rotor when positioned into the stator and allow for an exact measurement of where the rotor is to the stator.
