“…At the same time, articles began to appear on painrelieving therapy and analgesia with NSAIDs [67]. It is important to note that in this period younger adults began to be mentioned as the target population [68], with which studies, consistent with the pathophysiology of CLBP, began to recognize other risk factors for CLBP, not just degenerative ones. In the next period between 2015 and 2016 (yellow), studies focused on the duration of CLBP and quality of life [5,[69][70][71][72], thus broadening the picture of the causative factors for the occurrence of CLBP.…”

Background: Physiotherapy and chronic low back pain (CLBP) form a broad and fast developing research area. The aim of the article was to holistically, thematically and chronologically analyze and synthesise literature production and identify most prolific research entities and research themes. Methods: The article quantitatively and quantitatively analyzed research literature production harvested from the Scopus bibliometric database. using a triangulation of bibliometric and thematic analysis. For this, Excell and VOSwiever software were used. Results: In the Scopus database, 2843 data sources were found, which were published between 1974 and February 26, 2024. The growth trend has been linearly positive since the beginning of publication, and after 2018, exponential growth began. A review of the most prolific entities showed that the most literature was published in America, Europe and Australasia. The thematic analysis of the information sources identified six main themes, while the chronological analysis revealed three main areas of developments: assessment tools, CLBP processing and study methodology. Conclusions: The results of the bibliometric study presents a good starting point for further research providing Taxonomy and research landscapes as a holistic framework offering multidisciplinary knowledge about CLBP, while chronological analysis provides a basis for identifying prospective research trends.

The Progressing Cavity Pump artificial lift method for oil well production is well known in the oil industry, despite that a poor literature about PCP analysis is available. PCP automation based on ladder programming deploys information such as instantaneous rod torque, production line pressure, and rods rotation to name a few. The use of this information to analyze the well performance, identify imperfections and problems depends on a deep knowledge about the system well-PCP, but the procedures to do so are yet to be developed. To optimize the production and increase the mean time between failures in this type of well is necessary not only to improve the algorithm coded on the ladder programming loaded in the PCP automation PLC but also to develop a knowledge base where the skills and knowledge of the local PCP specialists could be easily coded. To analyze data deployed by the PLC and to improve the firmware customization, an intelligent system is being developed. This intelligent system is based on artificial intelligence concepts such fuzzy functions, coded in a way to easy acquire the PCP specialist knowledge on how to understand what is going on in the well and what to do to bring it back to a proper behavior. The present paper presents an intelligent system for automation of PCP wells capable of acquire and spread the knowledge of the referring specialist in diagnosis and solutions of problems during the well operation. Fuzzy agents are proposed in order to do an intelligent analysis of a set of PCP variables such as friction, motor, pump position, production and volumetric efficiency, ... The paper also describes the tools and interfaces designed to acquire the PCP specialist knowledge, the system implementation, and an acquired knowledge base example. Introduction Progressing Cavity Pumping (PCP) control is simpler than the control used in Sucker Rod Pumping (SRP) where a customized firmware is needed and demands a far more complicated analysis [4,6]. All the functionality needed to implement the PCP control can be obtained using ladder logic programming language. Ladder logic programming language is a generic programming language to be used in Programmable Logic Controllers (PLC) and is a well know and low cost development programming language. All the well data generated by the Ladder Program, see figure below, are collected by a communication driver and stored in a Data-base at the central office, in a non stop sequential pooling. This data-base is merged to others data-base such as production and well servicing data-bases through a corporate network. The resulted data-base is the data-source to the analysis presented in this paper. A Mamdani fuzzy structure [1] was chosen to represent the knowledge needed to analyze all the data gathered. The Artificial Lift knowledge collected from Artificial Lift Specialists (ALS) was broken in to small pieces and coded as Fuzzy Agents (FA), e.g. specialized agents to analyze hypothesis about well characteristics that has impact on the PCP performance such as friction, gas interference, motor HP, pumping efficiency, pump depth, paraffin, scale, sand deposition and corrosion [6]. This work extends the PCP analysis presented by Carvalho et alli [5] to an all Fuzzy approach. Fuzzy Concepts There are two popular fuzzy structures commonly used: the Mamdani [1] and Takagi-Sugeno (TS) [2] fuzzy structure. In this paper, the first one is adopted.

There is the higher fault probability under the bad work conditions of the rod pumping system.According to the failure of the sucker rod pumping installation, a comprehensive survey is carried out. There is many influence factors of deep well pump working downhole, not only influenced by the machine, wells, pumping equipment, but also by sand, wax, gas, water. Pump conditions can be diagnosed by surface dynamometer card, surface dynamometer card is the first-hand information collected in pumping well of oilfields. By analyze the Characteristics of the different fault dynamometer, Lay the foundation for the further fault diagnosis and prediction. The different pattern of the different dynamometer is important.
