Bubble tests for gas tightness
Vacuum, 1964Abstract 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.

Appraising a Tight Gas Discovery
EAGE workshop on Developments in Land Seismic Acquisition for Exploration, 2010This 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.

Looking for gas….in all the tight places
69th EAGE Conference and Exhibition - Workshop Package, 2007This article represents a personal essay describing the fundamental differences between conventional gas accumulations and ‘tight gas’ accumulations. We have become accustomed to looking for gas in reservoirs that have good porosity and permeability to provide high flow rates. We demand excellent reservoirs to provide economic accumulations.

Reserve Analysis for Tight Gas
SPE Eastern Regional Meeting, 2002Abstract Tight gas reservoirs present unique challenges to the reservoir engineer. Applying classical reservoir engineering techniques to these reservoirs is problematic due to the length of time required to reach pseudo-steady state flow and/or establish a constant drainage area.

Geology of Tight Gas Reservoirs
1986Tight gas reservoirs occur in low-permeability, gas-bearing formations that are present to some extent in all gas-producing basins worldwide. This is the first volume to bring together data on tight reservoirs for a variety of basins and different geologic settings. The papers in this volume discuss characteristics of some of the most significant tight

WELL TEST ANALYSIS IN TIGHT GAS RESERVOIRS
Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1977Abstract The subject paper has two main purposes. The first is to describe several interesting field case histories of well tests in tight gas reservoirs. These are given in sufficient detail to act as benchmark examples for comparison of similar analyses in the future by other investigators.

CIPC/SPE Gas Technology Symposium 2008 Joint Conference, 2008
AbstractAs the demand for energy worldwide increases, the oil and gas industry will need to increase recovery from unconventional gas reservoirs (UGR). To economically produce UGRs, one must have adequate product price and one must use the most current technology. Tight Gas Sands (TGS) contribute three quarters to the total U.S.

Multicomponent VSP imaging of tight gas sands
69th EAGE Conference and Exhibition - Workshop Package, 2005Abstract Low-porosity Bossier and Cotton Valley sands of the East Texas Basin, U. S., have only a small acoustic impedance contrast with the encasing shales but a greater relative contrast in shear-wave impedance. Vertical seismic profile (VSP) data acquired with both a near-offset and far-offset P-wave source clearly demonstrate the ...

Infill Drilling Potential in Tight Gas Reservoirs
SPE Annual Technical Conference and Exhibition, 2010Abstract Many operators of tight gas reservoir fields are interested in determining the infill well potential in these fields. Over drilling may prove to be uneconomical; whereas, under drilling would leave unexplored reserves in the ground.

A model for gas transport in microfractures of shale and tight gas reservoirs
AIChE Journal, 2015A model for gas transport in microfractures of shale and tight gas reservoirs is established. Slip flow and Knudsen diffusion are coupled together to describe general gas transport mechanisms, which include continuous flow, slip flow, transitional flow, and Knudsen diffusion.
