Error Control Coding Algorithms in High Reliability Telemetry Systems

Abstract

In the oil and gas industry, in the process of drilling support (geosteering) and well telemetry, there is a problem of transmitting reliable information via wireless communication channels. The quality of such communication, as a rule, suffers due to the presence of errors caused by interference. As the depth of the well increases, the problem becomes more extensive. In order to solve the problem, it is proposed to choose noise-resistant coding in the system of residual classes. This system parallelizes the execution of arithmetic operations, has corrective abilities and organically adapts to the neural network basis of intelligent field management. At the same time, there are constraining factors for the mass application of the RNS; for example, difficulties in implementing non-modular procedures, forward and reverse coding, and some difficulties in identifying and correcting errors. That is why the task of improving the RNS seems relevant not only for oil and gas complexes, but also for any digital signal processing applications focused on intelligent neural network management on the basis of non-positional computing. The material of the article is limited to the study of the noise immunity of linear codes of the deduction system and the development of algorithms for detecting and correcting errors.

Increasing the efficiency of extraction of residual reserves of hydrogen sulfide-containing deposits of the Uchkyr gas condensate field

“… Gas-hydrodynamic studies were not carried out regularly and not in full.  To increase the efficiency of extraction of residual reserves of the hydrogen sulfidecontaining deposit of the Uchkyr gas condensate field, it is recommended to establish geological and hydrodynamic control over its development [5][6][7][8][9][10].…”
