Impacts of sedimentology and diagenesis on pore structure and reservoir quality in tight oil sandstone reservoirs: Implications for macroscopic and microscopic heterogeneities

, 2020
Integrated analysis of reservoir quality, pore structure, depositional and petrologic characteristics, and types and degree of diagenetic alterations was done in this study by employing petrophysical evaluation, thin section observation, stable isotope ...

Seismic identification of tight-oil reservoirs by using 3D rock-physics templates

, 2021
Tight-oil reservoirs are classified as unconventional hydrocarbon resources, having a complex system of pores and cracks and low porosity/permeability. A good pore-crack connectivity is required for hydrocarbon production, but clay minerals filling the ...

Strategic Delineation of a Tight Oil Play

SPE Unconventional Resources Conference, 2014
Abstract This paper describes a comprehensive methodology to rank drilling locations in a very large, unconventional tight-oil area based on both surface and subsurface characteristics. A North American case study is presented. Operators entering new prospect areas with little well control must make decisions on locating ...

Flow Units: From Conventional to Tight-Gas to Shale-Gas to Tight-Oil to Shale-Oil Reservoirs

SPE Reservoir Evaluation & Engineering, 2013
Summary Core data from various North American basins with the support of limited amounts of data from other basins around the world have shown in the past that process speed or delivery speed (the ratio of permeability to porosity) provides a continuum between conventional, tight-, and shale-gas reservoirs (Aguilera 2010a).

Methods to determine the upper limits of petrophysical properties in tight oil reservoirs: Examples from the Ordos and Songliao Basins

, 2021
In large petroliferous basins, tight and conventional reservoirs are widely distributed. These reservoirs have significant differences in formation mechanisms, enrichment rules, and development modes.

Steam Injection in Tight Oil Reservoir

SPE Improved Oil Recovery Conference, 2018
Abstract Steam injection—a thermal-based enhanced oil recovery (EOR) process—is used to improve fluid mobility within a reservoir, and it is well known that it yields positive results in heavy-oil reservoirs. In theory, steam injection has the potential of being applied in light-oil reservoirs to enable vaporization of in-situ reservoir ...

Is US Tight Oil a 'Ponzi Scheme'?

SSRN Electronic Journal, 2019
As US oil and gas share prices languish, there is some nagging concern about the financial health of the industry. Despite turning the world’s largest importer of crude oil into a global exporter, questions linger about profitability and financial leverage – some skeptics have gone so far as to ask if the industry is a “Ponzi Scheme.” Moreover, as oil ...

Brittleness characteristics of tight oil siltstones

Applied Geophysics, 2018
Rock brittleness directly affects reservoir fracturing and its evaluation is essential for establishing fracturing conditions prior to reservoir reforming. Dynamic and static brittleness data were collected from siltstones of the Qingshankou Formation in Songliao Basin. The brittle–plastic transition was investigated based on the stress–strain relation.
