Shortage of electricity is one of the main problem in the development of rural areas in Pakistan. Photovoltaic techniques are generally attaining an escalating attention and they're to become very competitive alternative, additionally, environmental issues such as population and global warming impact are attracting experts towards green electricity sources such as solar systems. A standout amon...

Electrical Submersible Pumps (ESPs) are one of the most widely used artificial lift methods in petroleum industry. However, ESP failures unanticipated and common occurrences with significant financial impacts for operators. Analysis performance essential its design optimization. This paper presents a statistical approach diagnosing evaluating root causes failures. The analysis is based on field...

A new hybrid analytical model (HAM) based on conformal mapping (CM) method and magnetic equivalent circuit (MEC) is presented in this paper for electromagnetic modelling of cage rotor induction motors (CRIMs) used electric submersible pumps (ESPs). For every operating point, the iron parts are modelled with a non-linear MEC to calculate virtual currents, which represent influence magneto motive...

The problem of plastic and microplastic (MP, <5 mm in size) pollution has received widespread attention globally, with its presence being reported various environmental media. However, a lack standard sampling analysis methods is making it difficult to compare data across studies understand the source fate plastics MPs. Common strategies used MP natural waters include Manta net pump filterin...

We propose a novel approach to fault detection in rotating mechanical machines: fusion of multichannel measurements of machine vibration using Independent Component Analysis (ICA), followed by a description of the admissible domain (part of the feature space indicative of normal machine operation) with a Support Vector Domain Description (SVDD) method. The SVDD-method enables the determination ...

Gas and downhole water sink-assisted gravity drainage (GDWS-AGD) is a new process of enhanced oil recovery (EOR) in reservoirs underlain by large bottom aquifers. The capital intensive as it requires the construction dual-completed wells for production additional multiple vertical gas-injection wells. costs could be substantially reduced eliminating using triple-completed multi-functional These...
