The method comprises: acquiring a wellhead liquid production amount corresponding to each pumping indicator diagram of a rod pump unit (101); obtaining a wellhead gas production amount corresponding to each pumping indicator diagram of a rod pump well according to the wellhead liquid production amount...
A number of oceanic processes also act ascarbonsinks. One such process, the “solubility pump,” involves the descent of surfaceseawatercontaining dissolved CO2. Another process, the “biological pump,” involves the uptake ofdissolvedCO2by marine vegetation andphytoplankton(small, free-floating, photo...
To handle the nonconvex NLP model, they propose a heuristic method based on an iterative scheme in which a simpler NLP model is solved in each iteration. Computational experiments are conducted in order to assess the computability of the model by applying a global optimizer, and to evaluate ...
And it is too difficult to ensure that the gas injection volume does not reduce the performance of the pump or engine. Sign in to download hi-res image Fig. 13. Schematic diagram of direct gas injection system [40]. An oxidizer pre-valve filled with gas to serve as an accumulator was ...

but BPNN can handle regression tasks. Combining the heuristic genetic algorithm (GA), the GA-BPNN can search for more reasonable solutions to avoid falling into local optima. The bagging-BPNN needs a bootstrapping process to sample the training set and achieves multiple sub-learners with the out...
Figure 2. Diagram of the optimization of the well process conditions. At the initial stage, the user defines a list of the names of the parameters to be adapted and a list of reference parameters. It is possible to set arbitrary hard limits (using some of the reference parameters). The ...
The sub-cycle of the SEC is closed by a P1 pump, which feeds the water driving the ejector. Figure 4. A schematic diagram with the precise location of the most important junction points of the cold sub-cycle, where GTbap—gas turbine operating at negative pressure, SEC—spray-ejector ...
Sometimes users do not want this auto- matic behavior and would like to handle the vent valve manually. In this case, the Auto vent valve option should be set to be off. The RP button has a shortcut to the vent valve control. The default is on. The UGA control software also controls...
Pump Jack Diagram: Understanding Its Components and Functionality A pump jack, also known as a nodding donkey, is a device commonly used in the oil and gas industry to extract crude oil from an underground reservoir. This equipment is crucial in lifting oil from wells where natural pressure is...
