“…To regulate the operation mode, there are usually possibilities to change the power pump delivery. Besides, an adjustable ejector is used, which allows for changing the cross-sectional area in the fl ow channel at the nozzle, as is proven in papers [5][6][7] and described in patent [8]. In some cases described in patents [9][10][11] and in paper [12], the cyclic mode of *mikhal.mokhov@mail.ru medium fl ow through the ejector nozzle is considered, but such options have not yet been brought to the wide practical application.…”

A new scientifi c approach to gas compression using jet pump-compressor units has been developed. The new patented technical solution offers an opportunity for the effective application of jet pump-compressor units for the compression of various gases up to pressures of 10...40 MPa. The purpose of the ongoing research work is to develop new scientifi c principles for gas compression using jet pump-compressor units. The new scientifi c approach is associated with the improvement of the pump-compressor unit, with the provision of conditions for the periodic connection of the ejector during the implementation of a cyclic low-frequency working process. The results of the research fi ndings can be used to create energy-effi cient technologies for the compression and pumping of various gases; it can be methane, associated petroleum gas, nitrogen, carbon dioxide, air, hydrogen or other gases. The creation of cheaper and more economical pump-compressor units will allow for the solution of urgent production problems in hydrocarbon production, including those in remote Arctic oil and gas fi elds.

“…At the same time, the well-known compressor and turbine machines do not yet fully solve such urgent problems, because the operating conditions are complicated by the presence of liquid fractions and solid particles in the flow of the pumped medium [22,23,24,25]. There are known technologies of oil and gas wells operation, where jet pumps and compressors are used for liquid and gas pumping at high content of mechanical impurities, as described in patents [1,2] and papers [3][4][5]. Often an adjustable ejector is used.…”

The observed instability of the oil and gas market makes it necessary to intensify the exploratory scientific research for the development of advanced and inexpensive pumping and compressor equipment intended for oil and gas production and treatment. The ongoing research work is being undertaken with a view to modernize well-known technical solutions and develop new scientific principles for gas compression with the use of labyrinth compressors. From the published materials it became known that when designing labyrinth pumps, the screw auger on the pump rotor can be replaced with a set of vane wheels. This design approach should be transferred from the field of pumping technology to the field of compressor technology as well. At the initial stage of such research microlevel models of new turbocompressors have been developed to test their performance. Further, was made the transition from the low-cost physical experiments with micro-level models to a deeper study of the working process for the basic model of the compressor with the screw rotor. 3D-model development was carried out with the use of the SolidWorks 3D CAD-system. In order to undertake a calculation study, the FloEFD software package of computational fluid dynamics developed by Mentor Graphics Corporation has been used. The results of the research findings can be used for the development of energy-efficient technologies for the compression and pumping of various gases. The development of cheaper and more economical pump-compressor units will allow for the solution of urgent hydrocarbon exploration and production problems in abnormal operating conditions. Based on similar compressor units, there is a possibility to develop other sectors of science and technology as well.

The Experience of Using Jet Pumps with Hydraulic Pumping Bottom-Hole Assemblies to Reactivate Idle Wells in a Heavy Oil Reservoir in the East Soldado Field

This paper presents the performance and compatibility of using jet pumps with hydraulic pumping bottom-hole assemblies that were designed to work with hydraulic piston pumps in an attempt to reactivate idle wells in a heavy oil reservoir, offshore South-West Trinidad. The resilience of the already installed hydraulic bottom-hole assemblies made it easier to select jet pump as the artificial lift method for reactivation. Jet pumps were designed with dimensions to fit in the hydraulic bottom-hole assemblies. Assemblies were modified by using a 13 ft length of 2" pipe inside them to ensure that the seals in the pumps and the polished sections of the assemblies meet at the same depth. The production string from the triple string completion was isolated since only 2 completion strings were required for operation, leaving the power oil injection and fluid return strings active. Jet pumps were installed on 4 wells. Performance was monitored using sonologs to determine fluid levels and clamp-on ultrasonic flowmeters to determine injection and production rates. Results showed that drawdown was occurring and production was obtained from all 4 wells during the first 4 months of operation since submergences were lower than the static levels. After this period, the submergences of 3 wells increased to the static levels and test rates showed that these wells were not producing. The submergence of the 4th well was fluctuating and tested 76 bpd. On inspection, it was discovered that the throats and nozzles of the other 3 wells were plugged with seal fragments from the surface power oil pumps. The jet pumps were cleaned and reinstalled after which the submergences dropped drastically within the first month of returning to operation. From these results, it can be concluded that the jet pumps are compatible with the modified hydraulic pumping bottom-hole assemblies. All 4 idle wells completed in this heavy oil reservoir were successfully reactivated however the performance was affected by plugged nozzles and throats of the jet pumps by seal fragments from the surface power oil pumps. Submergences could be reduced to optimize all 4 wells by changing the nozzle and throat sizes to achieve optimum performance and production rates with the maximum power oil injection pressure of 2400 psi. This paper describes the experience of using jet pumps in the East Soldado field to reactivate heavy oil wells by making minor modifications to the existing hydraulic bottom-hole completion that was designed to be used with hydraulic piston pumps. The use of jet pumps was motivated by the need to reduce workover and operating costs together with the demand to increase oil production. This modification was successful based on the production and monitoring parameters obtained.
