Safety
--------------------------------------------------------------------------------------------------------------------------------------------------------Memory gauges are pressure tools. If careful procedures are not followed, pressure could be trapped inside the tool and the dismantling operation could become dangerous. Memory gauges are designed for and can be run in a sour gas environment. Usual maintenance and safety practices for sour service equipment must be followed in order to protect personnel using the tool and to ensure the longest possible tool service life. Memory gauges use lithium battery packs, which have special handling and disposal procedures. If the following recommendations are not clear or in case of doubt, please contact Metrolog at: Tel: + 33 5 61348074 Fax: + 33 5 61348066 Email:
[email protected] It is assumed that all relevant safety aspects, precautions and recommendations are known by the operators using Metr olog gauges.
As any downhole tool, a memory gauge can trap pressure. While every precaution must be taken to insure that pressure cannot enter in t he gauge by: regularly changing the O-rings, always cleaning the O-ring grooves before installing new O-rings, using the right O-ring type for a given environment, maintaining the HPC contact’s O-rings, from time time to time, time, tightening the the quartz quartz crystal crystal sensor on its holder with a dynamometric range, (see the following sections for more details), it is always possible to face the rare event that pressure entered in the tool but did not get out. It is particularly true in gas wells when the gauge has been left for a long time in the well: pressure could enter slowly by migrating through the O-rings but does not have time to bleed-off when the gauge is retrieved. Most of Metrolog memory gauges are built for this problem not to happen: either the pressure or the temperature probe of the AMEtrolog, TAMEtrolog, Flolog and Multilog will be pushed out of their seat if pressure inside the tool becomes higher that the outside pressure. CGMs, by their design, cannot incorporate such a safety feature. Metrolog proposes, for CGMs, a special electronics housing with a built-in relief valve. This relief valve must be maintained m aintained in perfect condition to be efficient. When gauges must be exposed to gas for a long period of time, it is advisable to run them inside gauge carriers full of high temperature oil (i.e. silicone oil) in order to avoid or limit the gas migration through the O-rings. Metrolog proposes these carriers for its different gauges.

Section 1
Safety
--------------------------------------------------------------------------------------------------------------------------------------------------------In extreme cases, for very long duration operation in gas wells, Metrolog proposes Fully-Welded CGM gauges. These CGMs do not have any O-ring and thus are the only solution for very long exposure to gas.
However, and except when Fully-Welded CGMs have been used, all the above precautions may not be sufficient to prevent pressure to enter the gauge. Strict procedures must thus be followed. When pressure is trapped in a memory gauge, two possible symptoms must alert the user: - the HPC sleeve is extremely hard to move and even stuck and - the electronics housing is very hard to move and its locking screws are hard to remove. Caution!! These symptoms are not exhaustive and pressure could be t rapped in the gauge without any evidence of such a p roblem.
A highly possible danger comes from the HPC contacts that could be expelled with a great force when the HPC sleeve is moved. The HPC contacts are glued in place but just to keep them in their seat not t o resist to high internal pressure.
Try to open the electronics housing first. In this case, all precautions must be taken to avoid the housing to be ejected violently (for the same trapped pressure, the force pushing on the housing is 10 times higher that the force pushing on the HPC contact.
All Metrolog's memory gauges have been designed to be run in sour service environment but, in this case, O-rings must be changed between every run and the bottom nose filled-in with high temperature g rease. The fluid.
has a built-in bellow, which protects the quartz sensor against the well
Complete buffer tube adapters or special bottom noses with a built-in buffer tube are available on request for sensor protection.

Lithium batteries used by Metrolog memory gauges are Lithium based batteries that are a potential hazard in case of wrong usage or wrong operation. We thus advise the users to observe particular precautions when using Lithium batteries, such as:
In order to protect the users, these batteries are equipped with a double level of fuse. One fuse is built in the cell itself, a second fuse has been added at Metrolog's request by the battery manufacturer. However, it is important to understand and respect the above rules and to treat these batteries with special care with a full understanding of their specificity; the protection by fuses is of no use in case of deformation or crushing of a battery by a mechanical action. If you have any question or doubt, please contact Metrolog.

The O-rings generally supplied by Metrolog are Viton O-rings 90 Duro. When replacing the O-rings, it is important to follow strict procedures in order to achieve the proper seals and their longevity: 1. Apply the minimum possible stress. Pass the O-rings around the smaller diameter possible. 2. Because of the inevitable stress applied when installing new O-rings, once installed, wait 2 minutes before placing the housing that will cover them. This gives time for the O-rings to relax and to take back their orig inal shape. 3. Metrolog recommends not to use back-up rings anymore. Wherever an O-ring and a back-up ring were used, install two O-rings of the same size in the same groove instead. (Figure M1 - O-rings installation )
For long or multiple exposures to gas, it may be needed to replace the standard Viton 709/90 O-rings by special O-rings made of other compounds or harder Viton like Viton 858/95 These O-rings have been designed to resist to explosive decompression and are used by major oil producing companies in gas fields for downhole and surface applications. Their main characteristic being to have a very low permeability to gas, they greatly reduce the gas entry (by diffusion) int o the gauge. Same replacement precautions apply than for standard Viton O -rings. In order to determine which compound is best adapted to each application, contact Metrolog and supply the flui d characteristics and chemical content.

(Figure M2 - 1.25" OD AMEtrolog parts description ) The HPC sleeve O-rings are to be changed frequently since the HPC sleeve will be moved at each run and because they protect the H PC contacts. On AMEtrologs, the HPC sleeve O-rings are changed without opening the gauge by removing the bottom adapter: 1
Put the gauge on a flat surface. Pull the HPC sleeve in the down position (uncovering the 2 HPC sleeve O-rings).
2
Remove the locking ring screw. Then remove the bottom nose, the bottom nose adapter and the locking ring by unsc rewing the bottom nose adapter.
3
Remove the locking O-ring, the HPC sleeve and the HPC sleeve O-rings.
4
Place new O-rings (n° 022) by sliding them around the sensor holder. Grease them with lubriplate grease.

(Figure M3 - 1.25" OD AMEtrolog CC parts description ) On AMEtrolog CC gauges, a similar procedure must be followed. However, since AMEtrolog CC do not have locking ring and do not use n° 022 O-rings for the HPC sleeve, the procedure becomes: 1
Put the gauge on a flat surface. Pull the HPC sleeve in the down position (uncovering the 2 HPC sleeve O-rings).
2
Remove the locking screw. Then remove the bottom nose and the bottom nose adapter by unscrewing the bottom adapter.
3

The HPC contacts must be kept clean at all times. Do not clean them with a sharp object nor with a metallic tool but with cloth or cleaning paper. There is no other routine maintenance on the HPC contacts than cleaning. However, HPC O-rings must be changed before l ong term jobs.
Refer to "Special O-rings for operations in gas wells" higher in this section. (Figure M10 - HPC contacts detail) 1
Strip the gauge as much as possible, following one or more of the procedures described above, in order to work on the part holding the HPC contacts only.
2
Heat the HPC contacts with a hot air blower for example, up to a temperature of 150°C (300 °F).
3
When the part holding the HPC contacts and the HPC contacts are hot, insert the tip of two small screwdrivers in the HPC contact groove and pull firmly to remove it. Do not pull by more than a few centimeters not to break the electrical connections.
4
Clean the bottom of the HPC contact seat. Remove first all traces of glue with a metallic tool without damaging the seal bore. Clean it then with an industrial cleaner, for example: Loctite 7063
5
Replace the 2 HPC contact O-rings on each contact carefully, to avoid cutting the connection wire on the sharp edges o f the HPC holes.
6
Glue the HPC contacts back in place using high temperature metal-metal glue, for example: Activator Loctite 7649 Glue Loctite 648 Press firmly each HPC contact in its seat during a few seconds, checking that each contact has reached the bottom of its seat in order for the HPC sleeve to travel freely above it.
7
Replace all O-rings and all other mechanical parts and re-assemble the gauge.

Multilog gauges can be used with various cages and spinners according to the minimum ID of the completion in which they will be run and to the maximum flow velocity expected. Four sizes of Multilog cages are proposed: 1.5" cage for 1.5" OD Multilog, 1 11/16", 2 1/8" and 2 7/8" cages for 1 11/16" OD Multilog. This size is the outside diameter of the cage and must be selected according to the Multilog size and the minimum ID of the completion. Please note that a 1.5" OD Multilog can only measure flow and fast response temperature or pressure and fast response temperature. Two spinner pitches are proposed: 2" and 5". The pitch represents the fluid movement when the spinner makes one complete revolution. According to the expected fluid velocity, the spinner must be chosen with the following limits: - minimum measurable velocity: 1 Hz = 1 revolution per second and - maximum measurable velocity: 100 Hz = 100 revolutions per second. The following table gives the part number for each part or each kit. Description Part number

The symptoms are not presented by order of importance but chronologically as they may happen during the use of the gauge. Some may me obvious, some more complex. It is assumed that the operator is following the standard procedure to access the gauge (for programming or reading) with the PC.
After clicking the 'Stop & Test' icon or the 'Read Data' icon, the message "Gauge Communication Failure, Gauge not Communicating" is displayed on the screen. There is no communication between the PC and the gauge for one or more of the following reasons: The communication port is erroneous. Check the port to which the HPC cable is connected it must be a serial 9 pin RS-232 port. Check that it is the port indicated in the Configuration|System menu. The HPC cable is not properly connected to the computer or the gauge. Check the connections by disconnecting the connectors and reconnecting them. In particular, on gauge side, check that the contacts are clean and in good condition, that the guiding pin of the HPC connector is in place and so that it was not possible to connect it upside down. Check also that the HPC sleeve is well pulled down and that the HPC connector does not rest on its edge but rests flat on the gauge body itself. The HPC battery is flat. Replace the battery by a new 9V battery. The HPC cable has failed. Use another HPC cable to determine for sure the reason of the failure. The gauge battery is highly passivated. Its voltage does not reach the minimum voltage to start the gauge. See later in this section for the depassivation of a highly passivated battery. The gauge battery is flat or missing. Replace it by a new battery if it is to run a job. To read the gauge data, disconnect the HPC extension from the HPC cable and connect the HPC cable directly to the gauge battery connector in place of the battery. The HPC cable now supplies current directly to the gauge. The gauge communication system has failed. Try to access the gauge with a GTI+PM (see below). See below "Electronics troubleshooting". DO NOT TRY TO REPROGRAM IT IF THERE IS DATA STORED INSIDE.

:
The battery is not able to start a gauge. It is extremely difficult to make a difference between a flat battery and a highly passivated battery. Both give the same low voltage when loaded. A battery that will not improve after the depassivation procedure must be considered as flat. The battery has been stored for a long time or it has not been used quickly after the last operation or it has been disconnected from the gauge (or the gauge has been stopped) before the battery had cooled down. Use the depassivation tool supplied by Metrolog . Connect the depassiver corresponding to the battery for a few minutes. For 10.5 V batteries (E or H), the battery indicator should reach the green zone after a few minutes. For 7 V batteries (F or J), the battery green LED should be On after a few minutes. If a battery does not depassivate after a few minutes, there is no need to persist and the battery must be dis posed.
See also the procedure described in the MetroWin help file.

Troubleshooting
---------------------------------------------------------------------------------------------------------------------------------------------------------
A few checks can be performed in the field if communication with a gauge is impossible. The procedure below shows how to detect a broken wire or a broken clock quartz. If all these checks do not locate the source of the problem, please contact Metrolog. (Figure (Figure (Figure (Figure (Figure (Figure
T1 T2 T3 T4 T5 T6
– AMEtrolog wiring) – CGM wiring) – 1" OD AMEtrolog wiring) – Multilog wiring) – HPC contacts wiring) – Gauge connector wiring)
For all the below checks, the gauge must be open and the MetroWin software must be running on a PC.
There is no communication with the gauge with the HPC interface cable. The gauge communicates with the GTI+PM. All other possible reasons have been eliminated by going through the 'Troubleshooting with PC' procedure as described above. The HPC cable has failed or an HPC interface cable wire is broken. Connect the HPC interface cable to the PC. Do not connect it to the gauge since this check is performed on the cable alone. Connect the two probes of a voltmeter to the two pins of its HPC plug. Check that a 12 V pulse appears during at least 1 s when clicking the 'Stop & Test' icon. If it does not appear, check all wire connections between the RS232 plug and the HPC interface box and between the HPC interface box and the HPC plug.
There is no communication with the gauge through the HPC contacts. The gauge communicates through the battery connector. A wire connecting an HPC contact to the circuit board is broken. Check the integrity of the HPC connection wires by checking them with an ohmmeter between the HPC contacts and the ci rcuit board.

There is no communication with the gauge. All other possible reasons have been eliminated by going through the 'Troubleshooting with PC' procedure as described above. A wire connecting the battery to the circuit board is broken. Disconnect the battery from the gauge. Check the integrity of the gauge connector wires by checking them with an ohmmeter between the gauge connector and the circuit board. Re-soldering the wire or replacing it would generally solve the problem.
The clock quartz is broken (generally after a very strong shock). Connect the gauge, connected to its battery (depassivated), to the PC via the HPC interface cable. If no battery is available, connect the interface cable in place of the battery by removing the HPC extension (see the MetroWin help file for detail). Use an oscilloscope with a 10:1 ratio probe (or a frequency meter). Connect the oscilloscope ground to the circuit board ground (JP7) and touch one of the leg of the clock quartz with the oscilloscope probe. Click the "Stop&Test" icon: a 1.843 MHz frequency should be measured. If the frequency does not appear, replace the clock quartz (D.00.M.QZ1). The new clock quartz must be placed on a thin layer of silicone f oam (for shock absorption) and held in place mechanically. Its legs must be protected with Teflon isolation tubing and must be bent in a way to prevent any contact (short circuit) with the electronics housing.
