Water Saturation in Tight Gas Reservoirs
Proceedings of Latin American & Caribbean Petroleum Engineering Conference, 2007Abstract 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 ...

Well Testing of Tight Gas Reservoirs
Canadian International Petroleum Conference, 2008Abstract A tight gas reservoir is commonly defined as a reservoir having less than 0.1 millidarcies permeability. There are several basic concepts and field cases of different well tests in tight gas reservoirs in the literature, but not presented as a general guide. In this paper, we gather valuable information and

Effect of Successional Reservoir Stimulation on the Production in Tight Gas Reservoir
2021Hydraulic fracturing and acidizing are the primary ways of reservoir stimulation for tight sandstone gas reservoir. The supplement of formation energy and complex fracture network induced by stimulation are favorable contributors to increase production.

Well Testing of Tight Gas Reservoirs
Proceedings of SPE Gas Technology Symposium, 2006Abstract 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.

Predicting the Performance of Tight Gas Reservoirs
SPE Europec featured at 81st EAGE Conference and Exhibition, 2019Abstract Engineers need to predict the production characteristics from hydraulically fractured wells in tight gas fields. Decline curve analysis (DCA) has been widely used over many years in conventional oil and gas fields. It is often applied to tight gas, but there is uncertainty regarding the period of production data needed for ...

Elements of reservoir simulation for tight gas reservoirs with water influx
Journal of Geotechnology and Energy, 2021At present, gas obtained from unconventional deposits plays an important role in the global economy as an energy factor. The simulation of the exploitation of this type of deposits is very complex and requires an individual approach for each case, which is extremely inspiring and interesting, therefore this article attempts to deal with the problem of ...

Petrophysics of Triple Porosity Tight Gas Reservoirs with a Link to Gas Productivity
SPE Western North American Region Meeting, 2011Abstract Petrographie work on thin sections from rock samples collected in tight gas sandstones of the Western Canada Sedimentary basin (WCSB) shows that the sandstones are composed of intergranular, microfracture + slot, and isolated non-effective porosities.

Practicalities of Stimulation in Tight Gas Reservoir
Proceedings, 2012Remaining development opportunities in the Southern Gas Basin of the North Sea are mostly confined to lower permeability sandstones and pose significant technical execution challenges and cost hurdles. Field operators have increasingly had to rely upon the adoption of multiple fractured, horizontal wells to achieve commercial rates, deploying ...

A numerical study of performance for tight gas and shale gas reservoir systems
Journal of Petroleum Science and Engineering, 2009Abstract Various analytical, semi-analytical, and empirical models have been proposed to characterize rate/pressure behavior as a function of time in tight/shale gas systems featuring a horizontal well with multiple hydraulic fractures.

Exploring for Fractures in Tight Gas Reservoirs, North Oman
International Petroleum Technology Conference, 2007This reference is for an abstract only. A full paper was not submitted for this conference. As gas operator on behalf of the Oman Government PDO has been active in a mature basin for ca 18 years. The traditional focus for gas exploration in the north has been on deep Haima reservoirs.
