Definitions
- This invention relates to the equipment and system used to' perform drill-hole survey and geological surveys of the subrsurface of earth, either onshore or offshore, wherein the equipment is given access to the subterranean strata by way of pre-prepared exploratory drill-holes.
- Geological surveys are critical activities used by mining and resource companies to determine the viability and operation of mines and wells.
- the accuracy and timeliness of the acquired data is an important factor in finding the next big ore deposit, or oil or gas well.
- time and precision are critical factors.
- Cost is an important factor as well.
- Lower cost surveys allow an operator to conduct more surveys within a set survey budget for a particular site. It is common practice that a series of drill-holes are created so that professional geoscientists, such as geologists can use a variety of equipment and survey technology and techniques to get as much data as physically possible that relates to the subterranean strata deep within the Earth's crust at that location.
- geological surveys are typically slow and costly to perform.
- the common practice is to have an on-site a drilling team that performs the drilling operation and creates the drill-hole, and then there is a survey team that subsequently works on the drill-hole with their equipment and performs the necessary geological survey.
- the survey team then returns to their office with their collected data and start processing it to generate a survey report that mining or resource companies use to guide the planning and decision making relating to the operation of an existing asset, or the creation of a whole new operation.
- Another problem associated with the common practice is that the tools and equipment used by the survey team are often highly specialised and complex, often requiring significant training and years of experience to operate correctly and effectively. In addition, the equipment is often expensive to maintain. Also there is currently only limited access to real-time data produced by the survey. Often this data is not analysed for days, weeks or months after the survey has been performed.
- Another problem is that drillers usually maintain a paper log of drill site activity, and this adds delays to the processing times of the geological survey data, and also adds delays to the processing of payments to the drillers for their work, and has the potential of introducing human error into the log.
- geological survey personnel such as geologists often take an ad-hoc approach to the storage of the acquired geological survey data.
- the present invention is a drill-hole survey and geoscientific data acquisition system that includes a down-hole tool including:
- the sensor control module, the at least one sensor module, and the connection means are each sized and shaped so that they can be placed within a drill-hole and can travel along the length of the drill-hole, and can travel along the drill-hole
- the sensor control module is a discreet control module
- each of said at least one sensor modules are also each a discreet sensor module
- each of the discreet control and sensor modules are inter-connectable via said data, control and electrical power connection means so that the series of modules are connected end to end to make one continuous elongate tool that contains a series of interconnected modules.
- the sensor control module controls the tool and provides electrical power to, and sends control signals to, and receives data from, each of the at least one sensor module.
- the tool collects data along the drill-hole.
- the tool collects geoscience data at discreet places along the drill-hole when the tool is stopped.
- the tool continuously collects geoscience data as the tool travels along the drill-hole.
- the tool includes data transmission means that sends data up to the operator at the ground surface, and said transmission means is either wired or wireless.
- the tool includes two wireless communication modes, one that is high powered, and the other that is low powered, and only one or the other is typically in operation at any one time.
- the high powered mode is used to transfer a large amount of data as quickly as possible, such as firmware upgrades to the modules, and/or large amounts of sensor data, and is subsequently switched off when no longer required to preserve the tool's battery power reserves.
- the low powered wireless communications mode is used to send short quick commands back and forth from the tool, and when only small amounts of data need to be transferred.
- the tool is capable of self-determining which wireless communication mode to use for any particular data transfer task, or the operator can manually select the wireless communication mode using remote commands.
- the tool is capable of continuously transmitting said geoscience data back to the operator while the tool is down the drill-hole.
- the geoscience data can be collected and stored within the tool, and this collected data can then be uploaded into a handset by an operator after the tool has been retrieved from the drill-hole.
- At least one gyroscope is included inside a discrete gyroscope module that is connected to, and forms a part of the elongate tool.
- At least one gyroscope is incorporated into the sensor control module.
- the gyroscope is a microelectromechanical type gyroscope, also known as a MEMs gyroscope.
- the gyroscope module includes four gyroscopes, and these are installed "nose to tail" so that the length of the gyroscope module is minimised.
- each sensor module includes one or more types of sensor technology.
- Typical sensor types used within a discrete sensor module include, but are not limited to:
- the down-hole tool is capable of being transported to the drill-hole site by the drilling operators in a disassembled condition, and the tool is capable of being assembled on- site and accurately calibrated so that the tool includes all the appropriate modules required for any particular geoscientific survey to be performed on a particular drillhole.
- the tool can be disassembled and safely stored after the survey operation has been completed by the drilling operators, ready to be transported to the next survey site.
- the discrete modules are screwed together to form the elongate tool.
- the sensor control module has the data transmission means at its end nearest to the opening of the drill-hole, and has data, control and electrical power connection means at the other.
- each of the sensor modules and the gyroscope module has data, control and electrical power connection means at each end, and when each discrete module is screwed together with a neighbouring module, the data, control and electrical power connection is made between each module that makes up the tool.
- the connection means includes an array of spring loaded electrical connector pins at one end, and a plurality of discrete electrical contacts at the other, so that when two modules are screwed together, the spring loaded pins of one module are forced into electrical contact with a desired electrical contact on its neighbouring module.
- each module includes a data logger that is relevant to that particular module.
- each module includes the capability of shutting down power to its neighbouring module to preserve its own operational integrity.
- the sensor control module includes a temperature sensor for the tool.
- the sensor control module includes a tamper sensor that indicates if any of the modules have been tampered with.
- each of the modules that makes up the tool includes a tamper sensor that indicates if the particular module has been tampered with.
- the tool is capable of processing the data acquired by the sensors within the tool, so that the amount of data that is stored within the tool and transferred or transmitted from the tool is minimised.
- the tool including each module, and/or ancillary equipment, such as the handset, and/or associated software, includes digital rights management technology that can be remotely enabled or disabled by an authorised third party, such as a distributor and/or owner of the tool, and wherein the tool, including each module, and/or ancillary equipment such as the handset, and/or associated software, can only be operated when the digital rights management technology is enabled.
- the present invention is a down-hole survey system that uses the down-hole tool that has been previously described, and includes:
- the tool controller is used to operate the tool, and collect the geophysical data acquired by the tool. This data is sent to the access point, and the access point is capable of wirelessly transmitting the acquired data over a wide area network, such as the internet, to the at least one server and plurality of computers.
- a wide area network such as the internet
- the tool controller is a ruggedised handset.
- the access point is capable of creating a gateway between the local area network at the survey site, and a wide area network, such as the internet, so that data to/from the down-hole tool, and/or to/from the handset, and/or to/from the at least one server, and/or to/from any one of the plurality of computers, passes via the gateway.
- a wide area network such as the internet
- the access point is integrated into the ruggedized handset so that the handset is capable of functioning as both the tool controller and the access point.
- the present invention includes the arrangement where both the at least one server and at least one computer are geographically remote from the survey site.
- the at least one server and the at least one computer in the plurality of computers are located within a master control facility, and at least one of the plurality of computers is located in a separate office remote from the master control facility.
- the master control facility both in conjunction with, or independently of, the separate office, prepares and dispatches a drilling program to a driller onsite, who will compare instrument data with a planned drill-hole plan so that the driller can make any last minute adjustments to the drilling program.
- the master control facility is capable of using the survey data it receives from the survey site so that the drilling program and drill-holes can be analyzed.
- the handset is capable of acquiring and transmitting data relating to the operational status and condition of the tool so that either or both the operator at the drill-hole site or the professional personnel at the master control facility are alerted if/when critical aspects of the tool has fallen out of proper calibration, or has in some other way moved outside of acceptable operational parameters for the particular survey operation being undertaken.
- Preferably personnel at the master control facility can react to alerts relating to critical aspects of the tool falling out of proper calibration, or in some other way has moved outside of acceptable operational parameters for a particular survey operation, by sending corrective and/or instructional data back to the drill site, including firmware for the hardware, and/or updated associated software, in order to attempt to get the tool, or an included module within the tool, back into proper calibration, and/or back to within acceptable operational parameters for that particular survey operation being undertaken, or to upgrade the equipment so that it operates at peak efficiency.
- an authorised third party such as a distributor and/or owner of the tool, including each module, and/or ancillary equipment such as the handset, and/or associated software, can enable or disable the digital rights management technology associated with that equipment and associated software, depending on the licence status of the operator at the time that the operator is preparing to use the equipment and/or associated software to perform a survey on a drill-hole.
- the handset has a simplified user interface that enables and empowers a driller at the survey site to perform highly specialised and complex survey activities under the supervision and instruction of professional geological survey experts, such as geologists, located at the master control, facility, or at a remote office, thereby giving the professional survey experts virtual access to the drill site and remote oversight of the survey operation for any particular drill-hole survey operation being undertaken.
- professional geological survey experts such as geologists

- Figure 2 is an isometric view of the electrical power, control and data connection means.
- Figure 3 is a side cut away view of the gyroscope module showing four gyroscopes installed.
- FIG 4 is a schematic of the complete survey system including the tool. Detailed Description of the Preferred Embodiments Turning firstly to Figure 1 we see an exploded view of the down-hole survey tool 1.
- the survey tool 1 can be assembled from a sensor control module 3 and a gyroscope module 13, and a plurality of sensor modules, selected from a kit containing a wide variety of sensor module types.
- the sensor control module 3 typically the gyroscope module 13 is connected to the sensor control module 3 via the external and internal screw thread pair 5 and 7 respectively.
- Each module has matching internal and external screw threads, thereby enabling the tool to be assembled in a wide variety of configurations.
- a different selection of sensor modules are assembled together for each specific survey task.
- the sensor control module 3 is the master controller for the device. It includes the power supply for the tool, as well as the controller and monitoring means for each other module in the tool assembly. In addition, the sensor control module 3 includes data receiving and transmitting means. An example of suitable means is the wireless data receiving/transition means 11. As an alternative to wireless means, the sensor control module could also communicate with the ground surface via a wire.
- the tool may incorporate two wireless communication modes.
- the first is a high power mode that is capable of sending and receiving comparatively large amounts of data more quickly and effectively.
- the other mode is a low power mode, and this mode is suitable for small amounts of data transfer.
- Typically only one mode is in operation at any one time.
- the high power mode consumes more power from the battery power reserves for the tool, it is only switched on when needed, and at other times it is turned off.
- the tool is capable of self-determining which mode it needs to use based on a variety of factors, such as the amount of data to be transferred, and/or whether there is enough power in the battery to be able to be used. In addition to this, either the driller, or a remote operator can remotely command the tool to use one mode or the other.
- the end of the sensor control module 3 furthest from the opening of the drill-hole includes a set of electrical contact rails. When a module is screwed onto the sensor control module, and electrical connection is made between them. This electrical connection permits the flow of data, electrical power and control signals throughout the tool.
- the sensor control module may also include one or more gyroscopes. In this embodiment, there is no need to have a separate gyroscope module 13.
- the sensor control module 3 may also include a sensor, such as a temperature sensor, thereby removing the need for including a temperature sensing module in the tool.
- the sensor control module 3 may include a tamper alert sensor that is capable of alerting the operator or owner of the tool to an unauthorised tamper event on any of the modules of the tool.
- some or all the modules include a respective tamper alert sensor that alerts the operator or owner of the tool of an unauthorized tamper event on any of the respective modules of the tool,
- Each sensor module 15 is capable of doing at least one specific sensor or survey task, including, but not limited to:
- Each sensor module may operate either autonomously, or may be controlled by the control module. Sensor data collected by a particular sensor module may either be stored locally in that particular sensor module, or the data may be stored in the control module, or a combination of both for the sake of redundancy.
- Each module within the tool 1 includes a data logger.
- FIG 2 we are shown opposite ends of a sensor module. We can see that there is an array of multiple spring loaded connector pins 17 at one end, and a plurality of concentric electrical contact rails 19 at the other. When two modules are screwed together, the spring loaded connector pins are forced into electrical contact with the electrical contact rails 19. Depending on the requirements for that particular module, the pins 17 are arrayed so that only the appropriate contact rails 1 are connected to.
- small bendable connectors are located between each module, thereby allowing individual modules to bend with respect to its neighbor. This assists in special circumstances where the tool needs to pass around a bend in the drill-hole that is would otherwise not be capable of passing in its rigid form.
- FIG. 3 we can see a cut away side view of the gyroscope module 13.
- the internals for the entire gyroscope module are capable of turning under the influence of a motor.
- the internals of the module are connected at each end to the bearings 23. The more gyroscopes that are installed in the tool thereby gives the tool a capability to reach an acceptable level of directional orientation precision in a shorter period of time, compared to a tool with fewer gyroscopes installed.
- MEMs gyroscopes are used inside the gyroscope module, and these are installed in a "nose to tail" configuration so that the length of the gyroscope module is considerably reduced.
- some, or all of the individual modules used in the tool are filled with a suitable substance, such as an oil, so as to dampen the rate at which temperature varies within the tool.
- a suitable substance such as an oil
- the system includes the down- hole survey tool 1 , a handset 27, an access point 29, at least one server 31.
- the access point 29 acts as a gateway between the local area network 35, and the wide area network, such as the internet, that connects to the remote server 31 and the computer 33.
- the server 31 is remotely located from both the survey site and the computer 33.
- the server is located inside a Master Control Facility 37 that can be physically located anywhere in the world.
- the computer 33 is located at a client survey office 39, also located anywhere in the world.
- Geophysical scientists, such as geologists can be located at either facility and can oversee and run survey remotely from the survey site. There is a high degree to communications flexibility designed within the system.
- the down-hole tool 1 is can be configured to communicate directly with the access point 29, or via the handset 27 to the access point, and also it can be configured to communicate directly with the computer 33 or the server 31.
- the master control facility 37 can monitor and maintain the equipment at the survey site in real time. If the module issues an alert that one or more of the modules have gone out of acceptable operational limits, the master control facility 37 can send back corrective instructions to the tool, and/or send instructions to the drilling operator about how to correct the problem.
- the master control facility 37 enables the geophysical professionals to remotely plan and control the drilling program for the client at a particular survey site.
- the survey plan would be sent via the wide area network link to the handset and down-hole tools onsite.
- the handset, or in some cases a laptop computer or tablet that is being used by the driller will compare the instrument data with the planned survey data and provide guidance to the driller on parameters such as actual drill-hole deviation from planned direction to suit the specific geology of the survey location.
- a client company such as a geoscience laboratory, at their office 39, can also enter in assay or other relevant information into the server records relating to the particular survey.
- the master control facility can perform analytics based on the geo- location of the survey and the theoretical accuracy of the down-hole tool based on its location on the earth can be accounted for. This is required because Gyroscopic based sensors change accuracy depending on the latitude at which they are used, while Magnetics tools require declination collections to calculate true north depending on the latitude and longitude.
- the other main aspect of the invention is that a user, such as a drilling contractor, or a mine site, can create a local area geophysical data network in a region by installing an access point 29 and that allows the down-hole tool and/or handset to directly and wirelessly communicate with both the master control facility's server, and/or client survey office 39.
- the access point 29 is incorporated into the handset, so that the handset also performs the function of the access point.
- down-hole tool 1 undertakes the majority of the sensor data processing and thereby reduces the amount of data that needs to be transferred to the handset. This reduces the processing required on the handset, and reduces the amount of data to be transmitted to the handset from the instrument, and to the master control facility server 31. For the user at the survey site, it offers them a simple handset which is very easy to use, and requires minimal training, thereby allowing a drilling contractor to also perform the physical operations required to perform the survey.
- Another important aspect of the invention is that the owner and/or distributor of the tool, ancillary equipment, and associated software, can remotely upgrade or service it as required so that the tool and its ancillary equipment and associated software can function at peak efficiency. Upgrades include updated software, or firmware for relevant hardware used either in or associated with the tool.
- At least some of the modules, and/or the ancillary equipment such as the handset, and any associated software, has digital rights management technology incorporated with it.
- the digital rights management technology When the digital rights management technology is activated, the tool, and ancillary equipment, is in a usable condition.
- the digital rights management technology When the digital rights management technology is disabled, the tool and/or ancillary equipment is in a non-usable condition.
- the distributor and/or owner of the tool is able to remotely enable or disable the digital rights management technology. This arrangement thereby enables the distributor and/or the owner of the tool and ancillary equipment to lease/rent out the equipment to an operator and ensure that it can only be used when the operator is in compliance with their relevant lease/rental agreement.
