some conventional oil reservoirs where recovery has been low. Major basins with potential for tight oil development are illustrated above. Western Canadian. 21 Jan 2016 Tight oil reservoirs are classified by the types of source–reservoir For in-source plays, reservoir rocks are not developed but source rocks 6 Jan 2019 At the end of the “12th Five-Year Plan,” the major oil fields have been explored for the large-scale development of tight oil reservoirs. During the 11 Jun 2019 In the development of tight reservoirs, the permeability of the rock possesses strong stress sensitivity with the dynamic change of formation Development of Reservoir Descriptions To Aid in Design of EOR Projects. of Horizontal Multistage Development in Tight Oil Reservoirs of the Western Canada Petroleum, reservoir and production engineers; researchers involved in shale and tight oil reservoir development; graduate-level petroleum engineering Engineering of Shale Gas and Tight Oil Resource Development A Workshop for Oil and gas rich shale reservoirs are typically found at least one mile or more Because shale formation rocks hold oil and gas tightly, conventional drilling is
14 Dec 2018 Two hybrid tight oil reservoir segments are developed in the Lucaogou Formation in the Jimusar Sag of southeastern Junggar basin, most of Tight sandstone is a reservoir which porosity is less than 10% and air The development of effective reservoirs has an important influence on tight oil and gas unproductive oil reservoirs in the Western Canadian Sedimentary Basin (WCSB). TIGHT MAJOR BASINS WITH POTENTIAL FOR TIGHT OIL DEVELOPMENT. Tight Oil is crude oil trapped in rock formations that have smaller pore spaces and lower permeability than traditional reservoirs. The development of fracking has been controversial due to environmental concerns. The process typically
Reservoir evaluation is a method for classifying reservoirs and the description of heterogeneity quantitatively. In this study, according to the characteristics of longitudinal physical properties of tight oil reservoirs, advanced experimental techniques such as nuclear magnetic resonance, high pressure mercury intrusion, and X-ray diffraction were adopted; the flow capacity, reservoir It is also the key performance indicator for developing the tight oil reservoir with underlying complexities. The process is initiated by the conventional static modelling which involves structural framework construction, distributing the petro-physical characteristics subject to the well logs and other available subsurface data. Tight oil reservoirs are adjacent to high-quality source rocks, which leads to relatively little difference in hydrocarbon-supply efficiency (Jia et al. 2014). Therefore, comparing with the hydrocarbon-supply mode, reservoir quality is more crucial for the development of tight oil reservoirs. Lessons learned from oil production of tight oil reservoirs in Bakken play[J]. Oil Drilling & Production Technology, 2012, 34 (2): 120–124. Wu Qi, Xu Yun, Wang Tengfei, .
In the same tight formation, the conventional DFIT method required typically over 12 hours for minimum in situ stress estimation, and over a month for reservoir pressure. This is just one example of how the TOC is developing practical tools to improve development efficiency for the industry. Major basins with potential for tight oil development are illustrated above. Canadian Society for Unconventional Resources www.csur.com Technologies Used to Recover Tight Oil The oil which is produced or extracted from tight reservoirs is similar to the oil which can be produced from conventional reservoirs; it is the application of Reservoir evaluation is a method for classifying reservoirs and the description of heterogeneity quantitatively.

Tight carbonate reservoirs, although less well understood and believed to require higher development costs and risks than conventional reservoirs, have become an important resource. Historically, tight reservoirs have been unpopular and unfavorable with geologists and reservoir engineers mainly due to difficulty associated with their development with no commercial productive value. It is also the key performance indicator for developing the tight oil reservoir with underlying complexities. The process is initiated by the conventional static modelling which involves structural framework construction, distributing the petro-physical characteristics subject to the well logs and other available subsurface data. Oil found in relatively impermeable reservoir rock. Production of tight oil comes from very low permeability rock that must be stimulated using hydraulic fracturing to create sufficient permeability to allow the mature oil and/or natural gas liquids to flow at economic rates. Tight Oil Consortium (TOC) is a multi-disciplinary consulting team of reservoir characterization and engineering experts. We focus on different scales of reservoir characterization ranging from pore to core scale studies in the laboratory and well to field scale analyses using production and geological/geophysical data. Tight oil reservoir permeability is less than or equal to 1 mD, and requires well completion to produce industrial oil flow (Zou et al., 2012, Zou et al., 2015). Due to the low porosity of tight reservoirs, oil and gas migration and accumulation processes differ significantly from those in conventional reservoirs.
