FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 17 NRU-1C Preparation Cleaning • Make sure that the top caps of the NRUs are clean and free of mud or wet material, or a large amount of dust. • Dust can be removed using a dry brush. • Mud can be washed off with clean water and a brush. Do not pressure wash the NRUs. • A very light soap/water mixture can be used to wash the NRUs, but must be rinsed off with clear water. ➢ Never use CRC or any other type of aerosol cleaning agent to clean the case of the NRU. Use of an aerosol cleaner or chemical cleaner could result in damage to the case. • Let the NRUs dry off prior to charging or downloading. Charging • See the sections for use of the Charging Panel page 25, and Portable Charging Case page 28. • Ensure that the NRUs are clean as stated in the section above. • The NRU LEDs will blink yellow while charging • The NRU should charge until the LEDs show solid green indicating full charge. ➢ If a NRU shows yellow blinking LEDs for over 12 hours, or never blinks yellow when charge current is applied. The NRU should be removed from charge and checked for defects. Shelf Mode • Shelf Mode – powered off. This can be done during data offload, parameter programming, or with NuSite in the field. See NuSite manual page 50, NuScribe manual page 46 o To take the NRU out of shelf mode, it will either need to be “bumped” or placed on charge. States • Deployed – in this state the NRU is active. The NRU is recording seismic data, GPS receiver is on at intervals, system clock is locked, and status is being broadcast. This state can be set during offload, parameter programming or by NuSite in the field. See NuSite manual page 48, NuScribe manual page 61 • Un-deployed – in this state the NRU is partially active. The NRU is not recording, the GPS receiver is in a low power mode, the system clock is not locked, status is being broadcast. This state can be set during offload, parameter programming or by NuSite in the field. See NuSite manual page 49, NuScribe manual page 61
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 18 Programming • See the NuScribe manual page 62. • Parameters for the current project will be set during programming, as well as checking firmware levels and correcting them if they are not current. • Setting the mode and state of the NRU at the end of programming or downloading is an operational decision. o Many variables can come into play when deciding which mode to set the NRU to. For example, storage time after programming, recording time required, days in the field, roll requirements, etc. o The NRU should be placed in Shelf mode if it is to be stored for a long period or if every minute of battery life is required, so that the NRU is only bumped on right before recording is required. o If the NRU is going to be placed in the field immediately after programming or offloading, it should be put in a Deployed state. o If there will be a small period before the NRU is placed in the field it should be put in an Un-deployed state to save battery life. Bumping • When a NRU has been placed in Shelf mode, one way to turn it back on is bumping. • Bumping involves momentarily touching a DC voltage to the MIMs contacts on the cap assembly. • The DC voltage can be between 9 and 12 volts, i.e. a 9-volt battery. Polarity must be observed. Positive terminal is on the top MIM. • If the bump is successful the NRU LEDs will blink white once. • After bumping, the NRU will emerge into either deployed or undeployed state depending on which mode it was in prior to shelving. NRU-1C Field Use Laying Out • The NRU should be placed as close to the receiver point pre-plot position or surveyed flag as possible. • The NRU can be planted by using the ADS (Automated Deployment System) or a manual deployment tool. o Both methods form a hole in the ground that perfectly fits the NRU chassis for good EarthGrip coupling. o The ADS will automatically plant a NRU.
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 19 o With the manual deployment tool, the NRU will need to be placed in the hole by hand and the top of the NRU stepped on with a foot to secure the plant. (Do not stomp on the NRU as that may cause foot or leg injury). • The optimal depth for the NRU to be planted, is with the bottom of the bottom clamp level with the top of the ground. The NRU can be planted down as far as having the top of the top cap below the surface and a thin layer of sand placed over it so the unit is not visible. • As with most seismic sensors, the closer to perfect vertical placement the better. Care should be taken when planting, not to deviate from vertical. Figure 10 • If the NRU is in shelf mode, it should be bumped on prior to planting it in the ground. Make sure that the bump was successful by watching the LEDs for a single white blink during the bump, then plant it. o For a NRU that is shelved in an undeployed state, it will need to be deployed next. See the NuSite manual page 48. o For a NRU that is shelved in a deployed state, once it is bumped on it will need to have the line and station numbers assigned in the NuSite database. See page 28 of the NuSite manual for Edit Deployment. o Ensure that the NRU is planted immediately after bumping to avoid having the geophone tests fail due to the NRU being moved around during the tests. o A green LED will indicate that all tests have passed and the NRU is recording. o A check should be made on the NuSite device being used for deployment, that there are no errors indicated for the NRU. • When a NRU goes to the line without being shelved, in either a Deployed or Un-deployed state, then either assign line and station, or deploy and assign line and station. Refer to the NuSite manual pages 28 and 48. o A check should be made on the NuSite device being used for deployment, that there are no errors indicated for the NRU. • When a NRU is in a Deployed state, it is broadcasting status messages. Any NuSite device within BLE range of the NRU will record that status into its database.
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 20 o It is recommended that each NRU be revisited with a NuSite device regularly, after deployment at a receiver point, to collect updated status. Regularity of the revisits would be dependent on operational considerations. o The longer a NRU is deployed in a location, the better the accuracy of the GPS position being recorded in the node. Collecting that GPS position contained in the NRU status with the NuSite device improves the accuracy of the NuCentre/NuScribe databases for later transcription of data. o Revisiting NRUs to collect status also improves spread QA/QC. Picking Up • Prior to physically pulling the NRU out of the ground, it must be Un-deployed with a NuSite device. Refer to the steps in the NuSite manual page 49. Un-deployment is very important information that is gathered with the NuSite database, and is synchronized to the NuCentre/NuScribe database for use during transcription. o There may be circumstances that require a NRU to roll through several receiver point locations prior to having data offloaded. In this case, un-deployment is extremely vital to later data offloading and transcription. • If it is required, for operational reasons, to shelf the NRUs during pickup, refer to the NuSite manual page 50 for the proper steps. Please take note of the cautions for those steps. • Use the extraction tool to dislodge the NRU from the ground. DO NOT HAMMER ON THE NRU TO DISLODGE IT. • During un-deployment, the NuSite device will receive updated status from each NRU it visits, before each unit is un-deployed. Downloading • Ideally each NRU should be brought back, after it is picked up, to the location of the NuScribe computer and the Download panels to download data from the NRUs. o As noted in the section above it may be, for various operational reasons, that the NRU could roll through several receiver points prior to download. • Prior to downloading, ensure that the top caps of the NRUs are clean and free of mud or wet material, or a large amount of dust. • Dust can be removed using a dry brush. • Mud can be washed off with clean water and a brush. Do not pressure wash the NRUs. • A very light soap/water mixture can be used to wash the NRUs if necessary, but must be rinsed off with clear water. • Let the NRUs dry off prior to downloading. o Never use CRC or any other type of aerosol cleaning agent to clean the case of the NRU. Use of an aerosol cleaner or chemical cleaner could result in damage to the case. • Follow the downloading process as described in the NuScribe manual page 61.
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 21 Chapter 3 NRU-1C-KCK
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 22 NRU-1C-KCK Description • The KCK model of the NRU is the same as the NRU-1C discussed in the last chapter, except there is no geophone element embedded in the case. • The KCK model has a KCK style 2 pin water tight connector built into the case in the place of the geophone element. Figure 11 • The electronics boards and specifications are the same as the NRU-1C, except for the geophone. • This model allows users to connect their own geophone strings to the NRU. • The KCK model can also be used to record the auxiliary channels from the source encoder unit, i.e. Timebreak, Pilot, etc.……. • This model can also be used in the field with the sources to capture source signals. Vibrator hardwires can be recorded as well as the signals needed for HFVS or other specialized vibroseis operations that require the capture of source signals. • Programming, downloading and charging procedures are the same as for the NRU-1C nodes.

Too much dirt or debris may keep the NRU from turning on or downloading properly due to the debris obstructing proper seating. o Remove power from the case o Use compressed air, preferably with a line dryer, to blow out the cups. o No CRC or other aerosol cleaning sprays should be used to clean the cups. A dry soft brush can be used to loosen debris in the cup prior to blowing it out with compressed air.

FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 37 Deployment Tool • The manual deployment tool is an easy to use device for creating a custom fitted hole for the NRU-1C node. • Operates as a slide hammer to drive a hole in the earth. Figure 18 ➢ The correct PPE should be in use when operating the manual deployment tool. Eye, ear and hand protection are recommended at a minimum. Be aware of finger pinch points on the tool. Back safety should be observed while operating the tool, straight back and feet planted in line with shoulders. • Identify the location for the NRU to be planted, as close to the pre-plot receiver point as possible. • Kick or scrape any loose dirt or gravel away from the point, this prevents any of that debris from falling back into the hole after removing the deployment tool. • Place the point of the tool firmly on the ground. • Grip the slide hammer handles firmly with both hands. Slide the hammer up to a height that is comfortable, then bring it down hard. Figure 19
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 38 • Care needs to be taken to keep the tool straight up and down to create a hole for the NRU that is as near to vertical as possible. • Repeat the slide hammer blows until the tool reaches the desired depth. • For the best NRU depth, the tool should be down so the ground is level with the bottom of the base collar, or just above it. In loose sandy soil, a deeper depth may be needed to compensate for small cave-in material. Start of job experimentation may be needed to find an optimal depth for the tool. Figure 20 • To completely bury the NRU, drive down until the top of the bottom collar is level with the ground. • Once the desired depth is reached with the tool, it needs to be rotated slightly, back and forth 3 or 4 times to consolidate the hole sides. Do this by gripping the 2 handles on the main body of the tool. Rotate while pressing down.
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 39 Figure 21 • To draw out the tool, holding the 2 handles of the main body of the tool, pull up slowly while rotating the tool slightly. Care should be taken while drawing the tool up to not dislodge dirt from the sides of the hole. • Place the NRU in the hole. o If too much material has caved into the hole and prevents the NRU from reaching the desired depth, redo the hole with the tool. • Step on the top of the NRU to firmly plant it in the hole. The NRU should be solid in the ground and have no room for any movement. A NRU with a good plant cannot be removed by hand easily. Never stomp on a NRU to plant it as that may result in injury to the foot or leg and possibly damage the NRU. Figure 22
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 40 Extraction Tool • The Extraction Tool is used to safely and effectively remove a NRU from the ground, • Due to the firmness of the EarthGrip plant, most NRU cannot be removed by hand. The Extraction Tool does this job. Figure 23 • The claw grips of the tool are custom shaped to fit onto the NRU between the top hex clamp and the bottom clamp of the NRU Figure 24 • Once the extraction tool is lodged in the groove of the NRU, the NRU can now be levered out of the ground.
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 41 Figure 25 ➢ Never hammer or kick the top of the NRU to try to dislodge it from the ground. This may damage the NRU or cause injury to the individual trying to remove the NRU. • If a NRU has been planted below the level of the ground, a shovel will have to be used to at least expose the NRU extraction groove for the tool to be used.
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 42 Chapter 9 Automated Deployment System
FIELD EQUIPMENT NUSEIS Geophysical Technology Inc Field Equipment Page | 43 Automated Deployment System V3 • The Automated Deployment System V3 is meant to automate the deployment of NRUs, effectively speeding up the process and reducing labor needs for laying out the nodes. • The ADS also adds consistency to planting the NRUs at “true vertical”, and the correct depth. Figure 26 • The system is powered by a Hatz diesel generator, running hydraulic power and electronic actuator. • Can be towed by most ATVs rated to tow the ADS weight. • The system is controlled by a pad type touch screen controller, with a sunlight readable screen. • With the addition of high precision GPS and navigation display, a single operator can drive and control the deployment of NRUs with great accuracy and speed. • The carousel design allows 160+ nodes to be loaded, ready for deployment.
