Problems solved by technology

Porosity and permeability measurements are readily measured with existing techniques, but are usually measured separately and the methods can be invasive, toxic, or both.
Effective porosity is also difficult to measure directly utilizing current techniques.

Abstract

Embodiments of the present invention relate to a method to determine formation measurements, the method comprising placing a sample in a reservoir, removing aliquots from the reservoir containing the sample or continuously monitoring the reservoir or headspace as the sample and reservoir equilibrate and analyzing the aliquots or readings sufficient to provide diffusion measurements.

Description

FIELD OF TECHNOLOGY [0001] Embodiments of the present invention relate to the measurement of formation rock properties by diffusion. Specifically, embodiments of the present invention relate to the measurement of porosity and permeability for application in the oilfield industry. BACKGROUND OF INVENTION [0002] Diagnosing the structure of porous materials is relevant to a broad range of scientific and technological problems. Knowledge of the fluid transport properties of reservoir rocks is important for the monitoring of contaminant levels in reservoir rock samples and for information related to extracting oil, such as in determining oil well value and characterizing formations for making real-time or near real-time decisions in drilling. Understanding porosity and permeability is important for determining the quantity and producibility of hydrocarbons in a reservoir system. These data can impact reserves estimates as well as production and development planning. [0003] Two of the mos...
