Analysis of a Discrete Object Control of Oil and Gas Pumping System under Uncertainty and Unfull Information Conditions

The results of repeated measurements of the acceleration of gravity by the Russian absolute ballistic field gravimeter GABL-M on points of oil and gas deposits in the permafrost over a five year period are presented. The changes of gravity acceleration by the absolute gravimeter and GRACE satellite were compared. The results of comparisons of differences gravity acceleration by ballistic gravimeter GABL-M and relative Canadian gravimeters CG5 were [i]shown. The errors in determination of parameters of the gravitational field ballistic gravimeter GABL-M and CG5 gravimeters group were presented. The method of measurement with the gravimeter GABL-M and the method of determining the vertical gradients relative CG5 gravity meters was described. The necessity of introducing corrections of hydrogeology is caused by influence of hydro geological factors on the gravitational field in the permafrost. They are comparable with the values of the field change in the result of gas pumping.

Dynamometer Card

Sucker-rod pumping systems are the most widely applied artificial lift equipment in the oil and gas industry. Accurate and intelligent working condition recognition of pumping systems imposes major impacts on oilfield production benefits and efficiency. The shape of dynamometer card reflects the working conditions of sucker-rod pumping systems, and different conditions can be indicated by their typical card characteristics. In traditional identification methods, however, features are manually extracted based on specialist experience and domain knowledge. In this paper, an automatic fault diagnosis method is proposed to recognize the working conditions of sucker-rod pumping systems with massive dynamometer card data collected by sensors. Firstly, AlexNet-based transfer learning is adopted to automatically extract representative features from various dynamometer cards. Secondly, with the extracted features, error-correcting output codes model-based SVM is designed to identify the working conditions and improve the fault diagnosis accuracy and efficiency. The proposed AlexNet-SVM algorithm is validated against a real dataset from an oilfield. The results reveal that the proposed method reduces the need for human labor and improves the recognition accuracy.

Maintenance is often considered a ‘necessary evil’ rather than a means of delivering value to owners and operators of physical assets, and means that maintenance seldom has the requisite importance and focus required. Optimal maintenance allows the delivery of maximum productivity and profit at minimum costs, and there are two ways of determining a nominally optimal maintenance solution: qualitative and quantitative optimization. Condition-based maintenance has long been recognized as an effective strategy for maintaining critical plant, and involves the regular inspection of equipment condition to determine the need for remedial maintenance activities. The periodicity at which inspections takes place is often ill-determined and appropriate quantitative analysis seldom takes place. Such an approach often leads to excessive direct costs and can result in significant indirect costs if asset failure is considered. This paper presents a solution to this problem; the quantitative delay-time maintenance model allows the determination of the optimum condition-based maintenance inspection interval. This approach is illustrated by the application of the model to the optimization of vibration analysis intervals for an offshore oil and gas water injection pumping system and demonstrates advantages when compared with conventional qualitative approaches.

Methodological Aspects

An important element in ensuring the stability of the gas transmission system of PJSC Gazprom is the reliability and safety of gas pumping units (GPU), their systems and equipment. Due to the aging of a large number of operating types and modifications of gas compressor units, the task of maintaining their healthy technical condition and ensuring reliable operation through maintenance and repair (MRO) is especially important. At present, when determining the project cost of GPU maintenance and repair work, indicators and data of different levels are used, and at the same time, data on the nomenclature, physical and cost indicators of work in the context of GPU types are not regulated and unified, depending on the full range of work performed by type MRO, technical condition and operating time of units. The article describes the methodological aspects of the development of resource-technological models (RTM) for maintenance and repair in the context of types (modifications) of gas compressor units, types and lists of works that will allow for the integrated formation of the project cost of work.
