This paper summarizes the experimental work done on the effect of petroleum resins on the process of relaxation the structural and rheological properties of petroleum paraffin solutions treated in ultrasonic field. A combined treatment of petroleum…
Wax can increase the viscosity of waxy crude oil, also precipitates and accumulates on the pipe wall, reducing the efficiency of pipe transportation. A strain of surfactant producing hydrocarbon degrading bacteria F-1 was isolated from crude oil…
The structural and rheological properties of resin-free model petroleum mixtures (MPM) with an asphaltene content of 0 to 6 wt % and the same mixtures with added 3.85 wt % petroleum resins have been investigated. The composition of the mixtures…
Crude oils are generally very complex chemical systems consisting predominantly of hundreds to thousands of hydrocarbon compounds from simple low-molecular-weight paraffin to high-molecular-weight waxes. There are many factors effecting wax…

Production from highly paraffinic crude oil wells poses unique technical challenges such as poor flowability and paraffin deposition on the production tubing. Paraffin deposition increases the lift load on the pump, reduces pump efficiency, and…
The transportation of heavy and extra-heavy crude oils from the head-well to the refinery is becoming important since their production is currently rising all over the world. Such oils are characterized by a low API gravity (103cP at 298.15K) that…
