Electric submersible pump (ESP) is the core artificial lift equipment to production oil from underground or deep sea surface. Its energy efficiency significantly affects global market and consumption. To explore effects of impeller meridian profile on hydraulic performance, a typical multi-stage ESP with medium specific speed was taken as research object. Based statically determinate control sh...

The work consists of the development a market-friendly 600 W photovoltaic battery-less water pumping system. system is composed four 280 Wp solar panels, an auxiliary 10 panel, three-phase converter and ½ horsepower (hp) submersible pump. electronic stage involves resonant DC-DC in series with voltage source inverter. novelties this are related to use fixed duty-cycle frequency for application,...

Oil production is a complex technological process that requires significant electricity consumption. The main consumers in oil and gas workshops are artificial lift facilities. Currently, among the objects of mechanized mining, installations electric submersible pumps widespread. When planning modes, it necessary to be able assess change power consumption parameters when changing parameters. pa...

Abstract The fate of carbon while passing through the rocky subseafloor ocean has direct implications on global cycle now and over geologic time, as well abundance distribution life. Many organic geochemical studies require larger volumes fluids than traditional hydrothermal samplers can provide, also rigorous steps to be taken prevent contamination. Hydrothermal Organic Geochemistry (HOG) samp...

Integrated Ocean Drilling Program borehole CORK (Circulation Obviation Retrofit Kit) observatories provide long-term access to hydrothermal fluids circulating within the basaltic crust (basement), providing invaluable opportunities to study the deep biosphere. We describe the design and application parameters of the GeoMICROBE instrumented sled, an autonomous sensor and fluid sampling system. T...

BACKGROUND: The study object is a high-speed drainage submersible electric pump, aimed to water polluted sea and fresh bailing out of drowned rooms shipbuilding industry facilities.
 AIMS: To obtain dependencies pump cavitation properties on relative diameter an impeller inlet at the high flow rate modes, determine kind head-capacity energy for various geometrical ratios in operational ran...

Phase III development of a micro-hydroelectric power generating system is focused on enhancing the system designed by Phases I and II. The previous phases focused on the use of the Gorlov Helical Turbine (GHT) to derive power from a fresh water environment, specifically the Stevens River in Vermont. Phase III exclusively focused on deriving power from an ocean environment and the construction o...

In the last few decades, several monitoring systems integrated with water level detection have been major research focus. Production boost and its sustainability depend mainly on sustainable supply, measuring level, avoiding waste of is an essential task for all stakeholders. Therefore, aim this paper to design implement a mobile phone-based remote control. This will be applied control operatio...
