A practical gas permeability equation for tight and ultra-tight rocks

Journal of Natural Gas Science and Engineering, 2021
Abstract Gas rarefaction phenomenon during gas flows in tight pore spaces makes the gas permeability of tight and ultra-tight rocks higher than the intrinsic permeability. Gas permeability equations in the literature usually assume a pre-defined pore morphology (or geometry) which may not reflect the real pore structure of rocks.

Advances in Tight Gas Completions - Noel Tight Gas Project

Abu Dhabi International Petroleum Exhibition and Conference, 2008
Abstract The Noel project has successfully employed unconventional fracing approaches and open hole horizontal wells to begin development of the Cadomin Formation in the Noel field in Canada. The Cadomin is a very difficult reservoir to exploit given that the reservoir is under pressured, has very low permeability and porosity.

On The Performance of Noncontinuous Tight Gas Sands

Proceedings of SPE Gas Technology Symposium, 1988
ABSTRACT This paper discusses the development and application of a stochastic three-dimensional reservoir model for gas-water flow. The model treats the occurence of natural fractures and shales in the reservoir as random, and as such the discontinuities may be arbitrarily distributed among the reservoir grid blocks.

Appraising a Tight Gas Discovery

EAGE workshop on Developments in Land Seismic Acquisition for Exploration, 2010
This paper presents a tight gas accumulation which was discovered in 2009 following the drilling of a vertical pilot hole and subsequent highly deviated hole. Both holes were successfully drilled using the under-balance drilling (UBD) technology which enabled gas flow to be recorded at surface while drilling the reservoir interval.

Bubble tests for gas tightness

Vacuum, 1964
Abstract Consideration is given to the operation of testing for gas tightness by observing the bubbles formed when a gas under pressure emerges from the leak into a surrounding liquid, particular attention being given to means for increasing sensitivity. The technique of detecting small leaks by the bubble method is described.
