This means that only part of the patch, ten lines, needs to be ready in order to begin productionparameter testing, can begin as soon as one line is laid out, connected, and tested4.2.1 Line TestsWhen the correct geometry has been applied to each WRU and the geometry accuracy has been confirmed, the Observer will begin line testing. In the warehouse before mobilization to the field the WRUs may have passed a series of BISTs (built in self tests), but these will need to be repeated after deployment. This can be done from the CSS, or can be done “ahead of the recorder” using an HRA in troubleshooter mode. Possible BISTs:• Equivalent Input Noise (EIN)• Total harmonic Distortion (THD)• Pulse• Calibration• Channel gain and phase errorWARNINGIn order to comply with FCC radio frequency (RF) exposurerequirements, the RT 1000 units must be installed so that a minimumseparation distance of 20 cm is maintained between the antenna(s) andall persons at all times during normal operation.

In addition, the following tests should be conducted of the backhaul communications:• Backhaul network confirmation (LTU-to-LTU-to-CSS test)• Backhaul connectivity confirmation (BSU-to-LTU-to-CSS test)The WRU BISTs can be executed at any time. If run during recording, any tests on the analog board or geophones will result in zero-ed data for the duration of the test. This may be desirable if one or more WRUs have reported a problem resulting in a skip-heal during high-productivity operations (skip-healing or self-healing is covered in another document). Tests can also be run during a pause in recording, or be sent to a queue to be automatically executed at the next pause in recording. Test results are written to the database, and can then be printed or written to a file, as in the case of delivering daily tests to the Birddog.Each set of tests will be stored as a parameter set in the tree. The following matrix illustrates WS’s recommendations for which tests should be run daily and monthly, and which are parts of continuous system health monitoringTBD4.2.2 Source Control TestsSeismic Source’s Universal Encoder (UE) is targeted to be the first source controller to be fully integrated with the CSS software. It will be connected to the CSS HW as part of an Ethernet LAN. The WS recording system shall support the same source types and configurations as the UE, including dynamite, multiple simultaneous vibrator fleets, and mixed source acquisition. When the shooters and/or vibrator tech have readied their sources, the Observer will establish radio contact, issue shooting commands, and investigate the content of the post-fire message. Test shots should be recorded, and correct timing, geometry, and header values should be confirmed. Further information on this workflow is found in the Production sectionVibrator similarity tests demonstrate the relationship between planned the sweep configured at the recorder and the measured ground force at the vibrator. This can
Draft20 RT 1000 v1.0 Deployment Guide R00.f© 2010-2011 Wireless Seismic, Inc. All rights reserved.Testing and Maintaining the EquipmentTesting the Layoutbe done over the source controller RF interface or when wired directly to the source controller. Hardwired similarity tests are more accurate, and the results will need to be compared to radio similarity tests. Similarity tests, as well as pulse tests to confirm that vibrators are synchronized, will likely need to be conducted at the beginning of the survey, and at sweep parameter changes. Radio similarities are conducted more frequently, measuring and recording raw ground-force versus time and phase versus time. Frequency of tests will be agreed to by the Oil Company and Seismic Contractor prior to the start of the project.Dynamite control testing is simpler than vibroseis. Timing between the source controller and blaster pack can be verified using a storage scope. This is done by hooking up one scope input to the encoder and the other to each decoder that is to be used.4.2.3 Acquisition Parameter TestingFor most surveys, except those where an Oil Company and/or seismic contractor have extensive local experience, the Oil Company will conduct a series of parameter tests. This will likely be under a separate pricing scheme in the contract, and may take a half to several days. In some cases an advance crew will be sent to an area to perform parameter testing. It may also take place with a subset of the patch, for example only a single receiver line. The parameters to be tested may include:• Dynamite charge size• Dynamite hole depth• Dynamite hole array (number of holes and pattern)• Vibrator array (number of vibrators and pattern)• Vibrator sweep configurationo Sweep lengthFor most surveys, except those where an Oil Company and/or seismic contractor have extensive local experience, the Oil Company will conduct a series of parameter tests.

This way, the parameter testing won’t consume any potential production time.You can economize by combining some of the tests.4.2.4 Built-In-Self-Test (BIST)• A method will be provided for synchronizing tests across all WLSs• Tests executed during deployment are for “go/no-go” purposes. The WRU will perform low-resolution evaluations of deployment tests and indicate the result with the battery LEDs. This is to save time and power and to reduce the effort required to write high-resolution evaluation in the WRUThere will be tests to implement in 2 places. We plan a “go no-go” test at the WRU that will be a simple calculation (not high precision) in order to assess if the channels and geophones are good. This could be done by Alex or someone like him. At the BSU application or LTU, the data for each of the test records (some tests have several records) would be sent from the WRU and processed with precision and the values for the tests calculated. I have someone that can write this software. The main reason to do this is when the system is audited the data and results for the same data, must be provided for analysis. If we do precision calculations at the WRU it adds complexity and may increase processing requirements• Tests executed from the central system are for verifying the WRU specifications.• WRUs will be commanded to execute internal and/or external tests. The data will be returned to the base station (in early development) or to the central system for high-resolution evaluationInternalDuring these tests the Geophone is disconnect electrically for the preamp. An internal test oscillator (where appropriate) drives the WRU analog channel in order to measure the characteristics of the Preamplifier and A/D. These tests should be run prior to running the external tests.• Equivalent Input Noise (EIN)• Total Harmonic Distortion THD• PulseCalibration• Channel Gain error and Phase errorB.

This means that only part of the patch, ten lines, needs to be ready in order to begin productionPickup and layout crews will be picking up lines behind production and laying them out ahead of production. Depending on battery charge state, equipment may circulate through staging or go directly from one line to the next.In order to make most efficient use of layout crews, it is common to lay out entire receiver lines at a time even if they are longer than the template. This way crews don’t need to spend time walking or driving from one line to the next picking up or laying out small amounts of equipment. However, if the size of the survey is large and receivers per line multiplied by the number of lines is larger than the number of channels available, it may be necessary to roll in the inline direction. In this case, it is necessary to be able to pick up and lay out WRUs in quantities smaller than a rib, for example increments of six WRUs.During inline roll operations, it may be desirable to add newly deployed WRUs to an existing (discovered) rib. The Observer can instruct the last WRU in a rib to poll for neighbors during recording. Newly added WRUs can begin recording immediately.

All rights reserved.6Demobilization6.1 Overviewxxx6.2 ProcessxxxAs soon as the Event Manager tool has determined that a WRU is no longer needed at that location, it will change color on the basemap. The Observer will need to consider the possibility of reshooting source points, which could happen if some recording failure is discovered later. Assuming no such reshoots, the Observer can undeploy the WRU or the entire rib. There will be no detrimental effect to either the ground electronics or the CSS database if the pick-up crew starts picking up the line before the Observer has undeployed it (e.g. if the backhaul is interrupted), as long as the Observer manually removes the picked-up WRUs from the deployed list at a later date. However, the preferred procedure for accurate asset tracking is to deploy from the CSS before physical pick-up.Another option is for an LTU technician to undeploy a rib using the HRA while connected into the LTU/BSU. This can only be done when the rib has finished all recording operations. This requires that a message indicating which WRUs have been undeployed be sent to the CSS after this action.Undeployment user action in the CSS can be either from the basemap or from a spreadsheet listing within the CSS application. An “are you sure” pop-up should be considered, especially for large numbers of WRUs and certainly for WRUs that haven’t been cleared by the Event Manager.Once a WRU or rib is undeployed by the Observer through the CSS, it is up to the staging manager to ensure the physical pickup and asset tracking of the ground electronics. At the end of the project, the primary need the Observer has of the CSS is to ensure that all positional and trace data has been stored, backed up, and delivered properly. He will then need to power everything down and secure all hardware for transport.

All rights reserved.TroubleshootingLED Chart7.3 LED ChartInsert the chart showing possible LED situations and what they mean.Throughout the project, there will likely be intermittent problems with the ground electronics. Failures can result from poor initial deployment, general wear and tear, lighting strikes or other acts of god, livestock and wildlife, or vandalizing (or curious) humans. When these problems must be solved physically, the Observer will use troubleshooters. Battery replacements fall into this category as well, if only an anomalous few need to be replaced within the spread.The troubleshooters, as noted in the User Story section, will have quick transportation (usually a mule or ATV), a collection of spares and tools, and a reasonable level of technical skill and training. The Observer will provide him with a printed list or file that can be loaded to a GPS. It will include:• Location (X/Y and line/station)• Faulty piece of equipment (geophone string, LTU/BSU, WRU)• Nature of problem (GPS failed, dead battery)• PrioritizationAs each issue is addressed, the troubleshooter will communicate the action to the Observer. At any point after this communication, the Observer will want to issue a command to the WRU in question, such as battery or geophone test. This can be issued immediately, tests that involve the analog circuit will result in zero-ed data from that WRU for as long as the test takes. It can also be sent to a queue, where the command is sent automatically when there is a pause in production. This is a part of the event management tool. This queue also handles duty cycle issues- where a WRU power state requires commands to wait for a particular interval.When a WRU has failed, the rib will automatically skip-heal. This means that adjacent WRUs will communicate around the dead WRU, so that recording can continue uninterrupted. If a troubleshooter replaces or repairs the WRU, re-creation of the rib can only happen when production is paused. This can be done on command, or can be queued as with other testing commands.In addition to troubleshooting reports, the Observer will be able to generate a battery report. This will contain all health information about any battery that has sent data to the CSS. Indexed by line/station or serial number, it will report the number of charge cycles, current charge state, and any other available statistics.Troubleshooting• All troubleshooting functions will be performed in the active and not the acquiring state• The units must be commanded to stop sending seismic data; however the cycle-mode will remain active to facilitate the troubleshooting process.

All rights reserved.TroubleshootingLED Chart• The CRA will contain functions that can be used with a BSU to perform the following on demand tests:o No GPS positionPosition is invalid because not enough satellites were acquired. This should only need to be done at initial WLS discovery. GPS should not be turned on when analog is on. Operator should be able to turn on the GPS receiver for a specified time. If no position can be determined then the operator should be able to review the neighbor information to determine the unit’s line and station and manually set it in the application.o WRU replacement (user initiated)A unit may need to be replaced for any number of reasons determined by the operator. The uplink and downlink neighbor of the unit being replaced would be told that its neighbor is being changed and it (downlink unit) should be sent an undeploy command by serial number. Once the replacement WRU has been changed, this unit should be activated by troubleshooter and it will execute the self and neighbor discovery process. The uplink and downlink neighbors of the replacement WRU should perform a WLS discovery with the new unit and add it to the list of units in WLS.o Geophone troubleshootingThis is a case where a geophone has been identified as bad and there is a troubleshooter at the unit. Select the units and perform any geophone test available. These tests can be run as a suite or individually. The units) would need to be told to turn on analog power and would begin to send data to CRA for analysis. For more detail on analyzing test data see “WRU built in self tests”.o Battery managementThis test when a battery is to be replaced and tested to verify that it is a good battery. Select the unit and request battery status the WRU. Display data for both batteries if present.o Analog channel evaluationThis test is performed when a geophone has been replaced with a new one and test is still bad. Run the internal tests to determine if the channel is bad and the WRU needs to be replaced. These tests can be run as a suite or individually. The units) would need to be told to turn on analog power and would begin to send data to CRA for analysis. For more detail on analyzing test data see “WRU built in self tests”.o Deployment test with tolerance parameters on demandIn the active state, propagate a command downlink in the heartbeat to an individual WRU to run the go-no-go test suite with a specified tolerance and indicate on LEDs test results and report pass/fail to the WS manager in next heartbeat.Note special care will have to be taken with tilt switches during battery replacement. A user-gesture may be used to assist this process.
