Compositional modeling of gas injection in tight oil reservoirs
The commercial development of tight oil reservoirs has reshaped the landscape of the petroleum industry in North America. However, the recovery factor (RF) of tight oil with primary depletion is very low, mostly below 10%. With a large volume of remaining oil in tight oil reservoirs, the successful …

Investigating the Environmental Impacts of Western Canadian Tight Oil Resources
… emergence of an unconventional resource known as tight oil. In 2017, oil production from this resource reached 430 thousand barrels per day, accounting for approximately 10% of all Canadian crude produced. Despite rapid development, the environmental impacts associated with the production and use …

Application of Data Analytics to Prediction of Initial Production in Tight Oil Reservoir
The main objective of this study is to develop a quick predictive tool to forecast IP for wells in LT reservoir in the three fields J, K and N. Data includes the petrophysical properties, completion history, lab and field measurements (PVT, pressure transient test, production and pressure data). …

Single Well Completion and Management Strategies for Enhanced Recovery of Tight Oil Using Miscible Gas Injection
Tight oil production relies on the multiple transverse fracture horizontal well completion design with 50 or more parallel propped hydraulic fractures distributed along a long horizontal well. Less than 10% primary oil recovery from these wells creates a strong incentive for enhancing recovery from …

Capillary pressure curve and liquid permeability estimation in tight oil reservoirs using pressure decline versus time data
Estimating oil recovery from shale is a difficult process because organic mudrocks have very low permeability (10nD - 100nD), high kerogen and clay content, a complex pore structure and low porosity (typically less than 10%). In addition, most of the pore sizes in organic mudrocks are within the …

Development of Scaling Crieteria for Waterflooding and Immiscible CO2 Flooding in Unconventional Reservoirs
As conventional oil reserves are depleting, the rising energy demand as well as advancements in well drilling and stimulation technologies have attracted increasingly interests in exploiting the unconventional oil resources (e.g., tight oil and heavy oil). Tight oil resources in Canada are mainly …

Forecast of Chinese Investment in US Shale Gas
… ventures will be set up between large Chinese oil and gas companies and small to medium sized US shale gas explorers, with a preference for tight oil and wet gas; in the long run, due to its transitioning nature, the joint venture investment will discontinue, and the Chinese companies' …

Investigation of Asphaltene Instability Under Gas Injection in Unconventional Reservoirs and its Impact on Oil Recovery Performance
… reservoirs, such as shale gas and tight oil formations, have become an important source of energy in recent years. However, these reservoirs often contain high levels of asphaltenes, which can lead to deposition and blockages in production wells and reduce the flow of hydrocarbons …
