2013年1月1日 · The Ugnu sands, with 12 to 18 billion bbl original oil in place, account for about one half of the heavy-oil resource and are the focus of appraisal activity to determine …

1992年9月1日 · At reservoir temperature, the dead-oil viscosity varies from 100, 000 to 10, 000, 000 cp [100 to 10 000 Pa·s]. The paper provides reservoir and geological descriptions of the …

The Ugnu consists of fine to medium-grained, unconsolidated sands with interbedded siltstone, mudstone, and coal that were deposited in fluvial and delta-plain environments. The oil in the …

2025年3月28日 · The promising results of this study indicate significant potential for liquid-CO2 alternating LSW injection as an effective cEOR technique for Ugnu heavy oils. 关键词 …

1992年9月1日 · The Ugnu deposit, located on the North Slope of Alaska, contains more than 6 billion bbl (954 {times} 10 {sup 6} m {sup 3}) of oil in place (OIP) in the Kuparuk area. The oil …

2025年2月1日 · Given the high viscosity of Ugnu heavy oil, which falls within the range of thousands of centipoise, a hybrid EOR technique is expected to be significantly effective for oil …

The Ugnu reservoir sands are unconsolidated and immature; they are classified as feldspathic litharenites to litharenites. From X-ray diffraction (XRD) analyses, the sands typically contain …

2013年8月12日 · The Ugnu formation contains the most viscous, biodegraded oils and standard production methods are ineffective. Heavy oils are viscoelastic fluids. Thus, it is critical that we …

Careful integration of log, core, and seismic data provided the basis for defining the reservoir architecture and depositional model. The primary reservoir zones are the Ugnu M sands that …

Completed objectives of this project included: 1. Developing a numerical reservoir simulation model for the Ugnu MB sand in the pilot area; 2. Evaluating the productivity of horizontal wells …
