The oil and gas market is unstable, which requires intensification of the exploratory research for working advanced and inexpensive pumping and compressor equipment out. Such equipment is crucial for more efficient hydrocarbon production. The ongoing research work is being undertaken to search and study new technical opportunities to develop advanced pumping and compressor equipment adapted to the complicated conditions of oil and gas production in solid abrasive particles in the flow of the pumped medium. New technology for gas compression has been evolved and further patented. The technology utilized a jet compressor unit to assist a turned on ejector while in the cyclic mode. Pulsed cycling of the ejector in contrary to continuous operation, increases the compression ratio of the multiplied gas. The energy recovery technology has been evolved, and further patented io increase the energy efficiency in the jet compressor unit. This technology applies a particular mesh turbine located at the flow part. The evolvement of smart turbines and compressor units was thoroughly researched. 3D-models have been developed in SOLIDWORKS 3D CAD system. The FloEFD software package of computational fluid dynamics has been used for computer modeling. In laboratory conditions, the performance of the mesh turbine prototype equipped with the jet control system has been successfully tested. Efficient and cheap compressor units solve many urgent issues in production connected with hydrocarbons extraction in harsh environments and those, which occur at the later stages of developing oil and gas fields. Specific research results can be used in other domains, including energy, transport, and robotics. [ABSTRACT FROM AUTHOR]

This article deals with the value of information in a natural gas exploration and production project. The financial analysis of natural gas fields is a fundamental part in the decision making process of investments by companies of the sector, government and agents of the financial market. An effective analysis can save important economic resources or even generate them when everything else indicates the opposite. During the stages of the exploration and production project, the concessionaire makes high investments in the acquisition of geological data, which increase the knowledge level of the asset in question. This case study examines this issue in light of the Real Options Theory, using the Bayesian inversion method to quantify the value of the information, exploring abandon and expansion real options. The relevance of this article is the presentation of an evaluation model in its state-of-the-art applied in a segment of high importance to the Brazilian economy. [ABSTRACT FROM AUTHOR]
