Top level - Data server and s Technologist Operator Network Data server APPLICATION The automation remote system is designed to monitor and control the remote devices and equipment. The system gathers data from remote oil and gas wells through sensors and prepare these data to optimize production. Generally the automation system is used for oi and gas wells equipped with the beam pumping units, progressive cavity pump, electronic submersible pump and water injection system. Internet (WWW) Middle level - Controller ARCHITECTURE The low level. This is level of the primary transducers and sensors to measure the data in the control points. The transducers are connected on RS-485 interface and used Modbus RTU protocol. Available to use any analogue and electronic devices. Data to register: -depth level and casing pressure; -dynamometer card, pump filling, production rate; -tubing pressure and temperature; -power and current of drive; -flow data. Depth level Load RS-485 Pressure Flowmeter Power The middle level. This level is organized by programmable controller under OS Linux. Controller is provided the routines with gathering information, logging, storing to the database, and also make the control action for equipment (i.e. pump, drive and etc.). Configuring of controller is made by distantly from remote computer, or at the site through Wi-Fi connection from notebook, PC-tablet or smartphone. Low level - Transducers Top level. This level is the server with database of registered measurements. Desktop client software «GEOSbor» is designed to operate with this database and prepare the data. Features OILFIELD gathering the data from remote transducers and sensors monitoring the remote objects with the predefined interval or on operator's demand; optimal watching for critical values of technological process (i.e. for oil depth level or pump fillage); recognition and prediction of failures and emergencies; pumping unit parameters calculation; remote control of equipment (pump on/off/ speed change); optimization of operation of pump equipment for best performance; wide range of alarms to limit damage from possible failures; forecast for possible repair and maintenance; support for sensors of other manufacturer; easy set-up and maintenance; remote configuration of controller; logging of registered data, user accesses and events; powerful reports, graph tenders, table reports.

Automatic echo level meter is mounted on the wellhead pipe of the casing annulus. This device allows to measure liquid level depth and casing pressure in oil and gas wells. DDS-102. Automatic dynamometer is mounted between carrier bars of the pumping unit. It measures load and position on the polished rod and registers the dynamometer card and calculates the pump efficiency. The most important device to measure pump fillage and production rate and predicting malfunctions. GS-AMTU. Pressure gauge registers the pressure in the point of measurement. GS-DVU. Flow meter registers the flow in a pipe. General usage is for water injection system. GS-DT-102. Power sensor registers the current of power supply of the pumping unit. All transducers have the protection from environment IP67. All transducers have the wide temperature range of operation. All transducers are certified. Power and connection units UIK is the main controller for gathering data from transducers, for storing, preparing and sending information to the central host by -connection. GS-PU-102 is a smartphone to carry data from controller to central host or sending the registered data from controller by in a case of problem with GSM-connection. GS-KSA is a solar battery. It is used in a case of absence of power supply at the oil well. BSI is a notebook for gathering data from controller and for configuration. GS-CNTR is a power unit for controlling of the pumping unit. Workstations are equipped with the special software GEOSbor that provides the receive data from remote units, make storing in database, shows the data on the screen and prepare reports. Software is realized the viewing of incoming information, showing the log of events, alerts and emergencies. Software can create the control action for equipment (turn on/off, VFD) and also to configure the setup of controller. For small projects it is used the local database. For big projects there is used client-server database. Features of GEOSbor: Remote control for equipment Remote configuration of controller Analysis and preparation of registered data Optimization of equipment operation Set-points for detection the critical condition and failures Wide range of alarms to limit damage from possible failures Access to data with the flexible filter Export data to the customer database EFFICIENCY This automation system gives the evident results on the low and middle production rate oil wells which situated in remote and hard-toreach areas. After using this system the idle time of well is decreased, overhaul life is increased, the cost of manual measurements is decreased. The oil well is operated in optimal mode with the high efficiency. The payback period is no more than 6 months. The system ensures the reduction of the operating costs due to controlling the equipment. In average, after one year using of this system: -increase the production rate of well (after well was optimized under inflow rate) (5-7%); -reduction the costs for repair due to forecast of possible failures (6-8%); -overhaul period increasing (8-12%); -decreasing the cost of manual measurements (10-30%). Implementation of the new technologies of smart oil well is very efficient for enterprise. Gathering the data from remote units gives the understanding to the technologists the complete condition of oilfield operation.
