Abstract The current problem related to poor-quality control of artificial lift operational parameters can be solved by means of development and application or real-time monitoring, control and analysis systems. As one way to solve this problem, TNK-BP has implemented the real-time SRP monitoring system. The SRP monitoring system is a specialized SCADA and expert system for SRP. The system displays and analyzes the information from the controllers, gives a possibility of remote control by means of controllers on the wells. SRP controllers are installed on the well sites in order to gather and analyze the data received from the transducers for SRP monitoring and operational control. The controller technology is based on processing a dynagraph for each pump jack stroke, which enables to ensure SRP control as per the rated parameters settings, diagnose the SRP condition, change the operational mode depending on the influx from the formation. To date the flow rates are measured periodically (once or twice a day), which is not enough. The monitoring and diagnostics system enables to receive real-time pressure data from the submersible transducer and use this information for automatic calculation of "instantaneous" flow rate. For this purpose the Company carries out pilot projects to try out the submersible telemetry systems (Russian-made) with additional transducers that record pressure and fluid temperature at the submersible pump discharge end and their transmittal to the external devices. Russian manufacturers of submersible telemetry are taking initial steps in producing telemetry systems with additional transducers. Also, in field development the oil companies face the problem of solids flow-back from the wells. The use of ultrasonic transducer to evaluate amounts of solids flown back from the well and their type is the most advanced practice. Ultrasonic transducer for solids detection has the following technological advantage: it enables to ensure optimal rate for the complex wells stock by means of data-based control and prompt real-time response to changes. In this paper the authors described application of such systems.
Abstract Nowadays the "Intelligent Field" concept is being actively implemented in TNK-BP, with Samotlorskoe field (OJSC "Samotlorneftegas") at the forefront in this conceptual area. The term "intelligent field" means arrangement of additional value of oil and gas asset by forming a cycle of gathering of qualitative data, treatment, modeling, decision making and their prompt performance. The concept is implemented step by step. At the first stage of implementation in 2009 – 2010 the main focus was on its technical constituent, the following technologies were reviewed and implemented: –use of different primary transducers for real-time data receiving; –upgrading SCADA, including use of remote control; –use of different real-time expert and simulating systems. Implementation of such technologies on a large scale adds value to the process of decision-making and oil production control. It has become evident that efficient implementation of technologies is impossible without changing production control processes both at the technological and organizational level. It also becomes essential to organize the process of implementation of such changes. In 2011 – 2012, in addition to the technical phase, the organizational phase was started in parallel. The issues related to technology influence on the current business processes and organizational changes required for efficient use of the technology were addressed to, the personnel's objectives were reconsidered and the team for implementation of changes was formed. The paper outlines technical aspects of technologies implementation and evaluates their influence on oil production process. The issues related to changes in organizational structure and business processes relevant to implementation of "intelligent field" technologies are presented. The effect resultant from technology implementation is evaluated.
