Abstract Although gas-lift is an established technology for improving the performances of oil production wells, simplicity, robustness and accuracy models remain to be fully resolved. As improvement on traditional practice, this paper proposes a new approach modelling performance gas-lifted wells at steady-state conditions. The conceptual framework splits wellbore into two segments. segments ar...

Oil and gas well delivery involves the execution of projects, with attention to safety, design specification, desired objectives, planned time, agreed budget. These projects involve drilling, completion, work-over, decommissioning/restoration (also known as abandonment) activities.
 Performance, respect oil process, is result comparing actual versus plan above-mentioned indicators. This me...

Orphaned oil and gas wells are abandoned for which the cost of environmental impacts usually falls on governments general public. Government agencies responsible well plugging often face funding shortfalls many orphaned remain unplugged. To address this support natural industry, federal already spending, or considering billions dollars to plug wells. Here, we analyze data United States Canada i...

The Deepwater Horizon oil spill triggered a complex cascade of microbial responses that reshaped the dynamics of heterotrophic carbon degradation and the turnover of dissolved organic carbon (DOC) in oil contaminated waters. Our results from 21-day laboratory incubations in rotating glass bottles (roller bottles) demonstrate that microbial dynamics and carbon flux in oil-contaminated surface wa...

Oil well diagnosis usually requires dedicated sensors placed on the surface and the bottom of the well. There is significant interest in identifying the characteristics of an oil well by using data from these sensors and neural networks for data processing. The purpose of this paper is to identify oil well parameters by measuring the terminal characteristics of the induction motor driving the p...
