The tools used to quantitatively evaluate flow volumes downhole are the radioactive tracer/gamma ray and the flowmeter. The radioactive techniques are used mostly ...

Welcome to this topic on Production Logging of Multiphase Flow in Horizontal Wells. In this topic, we will describe : Differences between multiphase flow in horizontal and ...

In oil reservoirs solution gas drive takes place when the reservoir pressure drops below the bubble point of the reservoir fluid and gas is liberated from the oil. The expanding volume of liberated gas helps to ...

Reservoir engineering seeks to economically optimize the development and production of hydrocarbon reservoirs. This requires answers to three questions:

Learning Objectives After completing this topic “Special Core Analysis“, you will be able to: Summarize the method and purpose for each test typically included in special core analysis (SCAL). Discuss some common subsurface interpretation techniques which use SCAL data. Introduction Special core analysis, commonly abbreviated to “SCAL,” includes laboratory procedures …

Historically, core analysis reports tended to consist only of some data tabulations, together with a brief cover letter.

Describe the different types of data and core information obtained as a complement to routine, special core analysis (SCAL) and the standard core description ...

After the core arrives at the laboratory, a detailed core description can be made in optimal working conditions. The description includes: The reservoir rock type ...

The pore spaces in rocks which form oil and gas reservoirs are always completely saturated with fluids. There are never any void spaces within the pores ...
