In this work, the objective is to get exact analytical solution of a generalized Casson fluid model with heat generation and chemical reaction described by Caputo fractional operator, using approach that Laplace transform method includes derivative. After solution, it will be studied impact order derivative most essential parameters included in modeling like Prandtl number, thermal Grashof mass...

The science of polymers, more specifically, synthesis, characterization, and physicochemical properties in solutions, has wide application in the petroleum industry, which uses polymers as components of fluids or additives to correct problems that affect oil production and/or increase production costs. Polymers are utilized during all phases, from drilling to treatment of oil and water. Researc...

The synthesis of biodiesel fuel from lipids (vegetable oils and animal fats) has gained in importance as a possible source of renewable non-fossil energy in an attempt to reduce our dependence on petroleum-based fuels. The catalytic processes commonly used for the production of biodiesel fuel present a series of limitations and drawbacks, among them the high energy consumption required for comp...

For three or more fluid phases in thermodynamic equilibrium and in contact with a solid surface, the Young equation can be used to find relations between the contact angles for different pairs of fluids. For an n-fluid-phase system, n(n-1)/2 contact angles can be defined, but there are (n-1)(n-2)/2 constraints between them, leaving only n-1 independent values of the contact angle. These constra...

Introduction Copyright 2004, Society of Petroleum Engineers Inc. There are many aspects of hydrocarbon production processes where understanding the flow of non-Newtonian fluids in porous media is of great interest. These include well drilling and construction, reservoir stimulation and production. In particular, complex polymeric solutions have been used for water-control purposes or to enhanc...

Dermal exposure to drilling fluids and crude oil is an exposure route of concern. However, there have been no published studies describing sampling methods or reporting dermal exposure measurements. We describe a study that aimed to evaluate a wipe sampling method to assess dermal exposure to an oil-based drilling fluid and crude oil, as well as to investigate the feasibility of using an interc...
