Introduction to Tight Gas Reservoirs

2013
Tight gas reservoirs represent a significant portion of natural gas reservoirs worldwide. Tight gas sand is generally characterized as a formation with effective permeability less than 0.1 md (Law and Curtis 2002).

Well Testing of Tight Gas Reservoirs

Proceedings of SPE Gas Technology Symposium, 2006
Abstract Advances in technology, strong energy prices and declining reserves in conventional gas reservoirs are encouraging oil and gas companies to consider the feasibility of exploiting large reserves trapped in tight (low permeability) gas reservoirs.

Water Saturation in Tight Gas Reservoirs

Proceedings of Latin American & Caribbean Petroleum Engineering Conference, 2007
Abstract Assuming a non-equilibrium scenario most of the non-conventional properties of gas-tight reservoirs are fully explained. The model is able to describe, among others, the following typical characteristics of these reservoirs: over-pressurization, "abnormal" low water saturation, unusually small or undetectable ...

Gas recovery potential of sandstones from tight gas reservoirs

International Journal of Rock Mechanics and Mining Sciences, 2014
Abstract The aim of our experimental study is to characterize experimentally the petro-physical properties of a set of sandstones originating from different depths from a single tight gas field, in order to improve our knowledge on their gas recovery potential. The initial characterization of these sandstones is performed in the dry state, and in the

Optimal Fracture Design For Tight Gas Reservoirs

Journal of Canadian Petroleum Technology, 1989
Abstract Type curves for the production of gas from artificially fractured reservoirs have been used to determine the fracture characteristics that maximize the expected economic return. It is shown that if possible fractures should be propped to yield a dimensionless conductivity of 4.2.

Volcanic Submarine Deposit as Tight Gas Reservoir

Latin American and Caribbean Petroleum Engineering Conference, 2009
Abstract In the Neuquen basin, center west of Argentina, a tight gas field was developed in submarine volcanic rocks. The field called Cupen Mahuida is a faulted anticline, which produced oil and gas from the upper formations. This deeper reservoir was discovered in 2001.

Cold-frac Technology in Tight Gas Reservoirs

Proceedings, 2009
For the fracturing processes several frac fluids were presented, described by their properties and behavior in the reservoir formation and the practical experiences in using. Energized fluids such as CO2-foam or commingled CO2 fluids are predominantly used for the optimization of the backflow and the aimed proppant transport.

Tight gas reservoir characterization from seismic attributes

69th EAGE Conference and Exhibition - Workshop Package, 2007
With the development of seismic technology, more and more seismic attributes come into being. More information than just time reflection is used to prospect hydrocarbon reservoirs. The study and interpretation of seismic attributes provided researchers with some details about geometry and physical parameters related to sedimentary facies, sands and ...

Unconventional Fracturing Fluids for Tight Gas Reservoirs

SPE Hydraulic Fracturing Technology Conference, 2009
Abstract Many tight gas formations are water-wet and under-saturated where the initial water saturation in the reservoir is less than the capillary equilibrium irreducible water saturation. The use of water-based conventional fracturing fluids causes water to be trapped in the near-wellbore region, thereby significantly impairing the ...
