simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Optimal Scheduling of Refinery Crude-Oil Operations

This thesis deals with the development of mathematical models and algorithms for optimizing refinery crude-oil operations schedules. The problem can be posed as a mixed-integer nonlinear program (MINLP), thus combining two major challenges of operations research: combinatorial search and global optimization. First, we propose a unified modeling approach for scheduling problems that aims at brid...

[Liver enzyme abnormalities among oil refinery workers].

OBJECTIVE Occupational exposure typical of an oil refinery may alter liver function among the workers. Thus, the objective of the study was to identify risk factors for liver enzyme abnormalities among oil refinery workers. METHODS The workers at an oil refinery in Northeastern Brazil underwent routine annual medical examination from 1982 to 1998. This case-control study investigated all the ...

Analytic information technologies in oil refinery

Problems of constructing analytical information systems and their application in controlling industrial processes at oil refining enterprise are considered. Systems being focused on control decisions support problem are regarded. Basic tasks, arising at constructing such systems and the ways to overcome them are listed. The appearance of multipurpose analytical information system (MAIS) is deve...
