This article presents new approaches to solving one of the problems encountered in many oil fields - the disposal of gas accumulating in the annular space of production wells operated by walking-beam pumping units. This question is relevant because the accumulation of gas and the increase in its pressure affects the depression reduction and the fall of the dynamic level of the liquid, adversely affecting the downhole pumping equipment operation. Critical annular pressure is a value above 10 atm. Traditionally in order to bring the annular gas pressure in line with the linear, reverse wellhead valves installed in the wellhead fittings were used. The use of these valves reduces the annular gas pressure, but does not solve the problem of its subsequent disposal. The emphasis is on the technical and economic efficiency of the proposed associated gas utilization method.

The paper reveals the ways and means of improving the quality of training graduates in the field of "Oil and Gas Business" through a competence-based approach implementation to the content of vocational education modernization. The article provides a rationale for the expediency of using the task approach in the formation of professional competencies among students of a technical university and reviews the experience in implementing this approach. The authors emphasize the importance of the "mathematics" discipline as a basis for vocational training, special attention is paid to defining the types of competencies and general of bachelors' professional abilities formation, with an emphasis on reflecting the problems encountered in organizing educational material in accordance with the requirements of the 3rd generation state educational standard. This article analyzes the basic concepts of "task" and proposes the authors' understanding of the term "task". The authors presented the experience of developing practice-oriented tasks for students of a technical university. The experience this technology implementation in the study of "Mathematics" in the oil technical university in accordance with the requirements of third-generation standards is described. Special attention is paid to the technology of professional competencies of students of a technical university formation. This article describes the stages of the learning process organization when implementing the technology of the task-based approach to learning. Specific examples of organizing the methods of the professional competencies formation are considered. The authors reveal the essence of the mathematical task as the main means of forming the competence of technical university students, show the relevance of using task approach in the learning process and suggest a specific method of key competencies forming through technological problems solving. 1. Introduction

Abstract. The article describes the innovative approach when predicting the resource potential efficiency of petrothermal energy. Various geothermal gradients representative of Bashkortostan and Tatarstan republics regions were considered. With the help of nomograms, the authors analysed fluid temperature dependency graphs at the outlet and the thermal power versus fluid velocity along the wellbore. From the family of graphs plotted by us, velocities corresponding to specific temperature were found. Then, according to thermal power versus velocity curve, power levels corresponding to these velocities relative to the selected fluid temperature were found. On the basis of two dependencies obtained, nomograms were plotted. The result of determining the petrothermal energy production efficiency is a family of isocline lines that enables one to select the optimum temperature and injection rate to obtain the required amount of heat for a particular depth and geothermal gradient.
