Acidizing flowback optimization for tight sandstone gas reservoirs

Journal of Natural Gas Science and Engineering, 2015
Abstract The physical properties of Sichuan tight sandstone formations include low porosity and low permeability. Fortunately, micro-fractures are well developed in this area, and the development of a reservoir is thus possible. Acidification can repair reservoir damage and improve single-well production; however, gas well production can change after

Experimental investigation of spontaneous imbibition in tight sandstone reservoirs

Journal of Petroleum Science and Engineering, 2020
Abstract Based on field conducts, it is found that a lower flowback rate results in a higher oil recovery in a tight sandstone reservoir. Spontaneous imbibition, as a main mechanism of oil production increment for this phenomenon, has been paid more and more attention.

Tight Sandstone Reservoir Renaissance: Baimiao Gas Condensate Field

SPE Annual Caspian Technical Conference and Exhibition, 2014
Abstract Gas condensate has become very important because the liquid makes it a high-quality hydrocarbon fluid. Tight gas condensate reservoirs may contain large reserves, but can be extremely costly to develop. The Baimiao gas condensate reservoir is a deep, structurally complex, low- permeability play with a high condensate yield.

Well Spacing Optimization for Tight Sandstone Gas Reservoir

Proceedings of International Oil and Gas Conference and Exhibition in China, 2010
Abstract In the past five years, tight sandstone gas reserves amounted to almost 50% of the newly proved natural gas reserves of PetroChina Co., Ltd. and will be one of the main targets of natural gas production for a long term. Means to determine the reasonable well spacing are the key topics in the development of tight ...

Pervasive Tight-gas Sandstone Reservoirs: An Overview

2008
The objectives of this chapter are threefold: (1) to provide a historical perspective on considerations of pervasive tight-gas accumulations, (2) to provide some observations on the present understanding of these accumulations, and (3) to anticipate where the industry is headed in the future.

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

Models for Saturation of the Tight Gas Sandstone Reservoir

Petroleum Science and Technology, 2014
The conventional model of formation saturation is restricted in well logging interpretation of tight gas sandstone because it is difficult to eliminate the influences of abrupt change of mineral component content. This paper studied the Triassic Xujiahe formation located in northeast Sichuan Basin, which has large variation of carbonate content between

Dynamic Fractures in Tight Low-Permeability Oil Sandstone Reservoirs

SPE Reservoir Characterisation and Simulation Conference and Exhibition, 2017
Abstract So far in China, unconventionally low-permeability oil sandstone resource has become the first contributor of proved reserve, and is occupying the most important section of oil production in near future. The low-permeability reservoirs have been primarily developed by waterflood, and therefore display a series of new and ...

Classification of tight sandstone reservoirs based on NMR logging

Applied Geophysics, 2019
The traditional reservoir classification methods based on conventional well logging are inefficient for determining the properties, such as the porosity, shale volume, J function, and flow zone index, of the tight sandstone reservoirs because of their complex pore structure and large heterogeneity.

Reservoir Geology of Some Tight Clinton Sandstones, Eastern Ohio

Proceedings of SPE/DOE Low Permeability Gas Reservoirs Symposium, 1985
ABSTRACT In an effort to better understand the geologic and engineering factors that explain the production performance of the tight Clinton sandstone of Eastern Ohio, logs, completion data, and production performance records were evaluated for a number of Clinton sandstone wells in east central Ohio.
