This work studies a series of factors influencing erosion-corrosion in oilfield gathering pipelines steel using the home-made testing pipe flow loop. Results showed that was corroded oil-water flow. The corrosion rate increased with velocity on whole, and addition solid particles would intensify localized corrosion. For test added 2 wt% quartz sand at m/s, portion pure erosion accounted for 47....

The viscosity of polymer liquid is an important parameter used in oilfield. Understanding the loss rule and regularity will help to improve distribution water injection quality ensure effective liquid. According oil-water data previous flooding fluid, it found that within range 5%-20%, with average 9.8%. reasons single well pipeline are complex varied, which closely related reducing substances,...

The knowledge and the forecast of the parameters which rule the down flow models in oil extraction and transport are today of paramount importance. In particular the extracted oil is mixed with water and gas in rates, which differ not only from different wells, but also on the same well during its life. The main problems involved with the measurement of the flow rates are: well exhaustion, crit...

Permeability is a very important engineering property of soils and finds utility in a number of soil engineering problems such as yield of wells and seepage through and below the earth structures. It controls the hydraulic stability of soil masses. The permeability of soils is also required in the design of filters required to prevent piping in hydraulic structures. However, the determination o...

This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...

A new analytical equation for prediction of temperature profile of a buried gas pipeline is developed. Utility of this equation is illustrated by its application to corresponding states principle. The resulting equation is tested through prediction of the actual Schorre data. It is shown that the new equation can predict temperature profile more accurately than the others without using any char...

In the design of a water supply network, the use of traditional formulas of the peak factor may lead to over-dimensioning the network pipelines, especially in small towns. This discrepancy is probably due to changes in human habits as a consequence of a general improvement of living conditions. Starting from these considerations, and given the availability of a wide random sample data, an analy...
