Can Associative Polymers Reduce the Residual Oil Saturation?

SPE EOR Conference at Oil and Gas West Asia, 2016
Abstract The oil recovery potential of acrylamide-based, associative thickening polymers has recently been evaluated in a coreflood study of our department. Associative polymers are anionic, water-soluble copolymers modified with varying degress of pendant hydrophobic groups. By intermolecular interactions of these hydrophobic moieties a

Interwell Residual Oil Saturation at Leduc Miscible Pilot

Proceedings of SPE Annual Technical Conference and Exhibition, 1990
ABSTRACT An interwell test for residual oil saturation to waterflood (Sorw) was successfully conducted at the Leduc miscible pilot during August of 1987. Although the principle of the test was first disclosed by Cooke in 1971, lack of suitable tracers and interpretative techniques would have hindered previous attempts to apply the test ...

Determination of Residual Oil Saturation by Use of Enhanced Diffusion

SPE Reservoir Evaluation & Engineering, 1999
Summary The enhanced diffusion method (EDM) exploits the diffusion contrast between oil and water separating their respective nuclear magnetic resonance (NMR) signals. Unlike standard NMR logs acquired with short interecho time (TE), measurements, EDM data are acquired using long TE accentuating diffusion.

Residual Oil Saturation in a Pure Gravity Drainage Regime

Proceedings of International Thermal Operations and Heavy Oil Symposium, 1997
Abstract Accurate quantification of the residual oil saturation impacts the reserves calculations. This investigation which addresses the role of gravity drainage in lowering the residual oil saturation was a part of an overall focus to improve the understanding of various recovery mechanisms in production of oil ...

Determination of Residual Oil Saturation With the Borehole Gravity Meter

Proceedings of Middle East Oil Technical Conference and Exhibition, 1985
ABSTRACT Use of the borehole gravity meter (BHGM) to measure remaining oil saturation is a method new to the industry. The technique is described, and its applicability to Middle East reservoirs is discussed. Results of an extensive error analysis are presented.

Determination of Residual Oil Saturation Using Enhanced Diffusion

Proceedings of SPE Annual Technical Conference and Exhibition, 1998
Abstract The potential use of NMR as a direct indicator of hydrocarbon saturation via techniques such as the Differential Spectrum Method (DSM) has generated significant interest in the petrophysical community in recent years.

The Myth of Residual Oil Saturation in SAGD - Simulations Against Reality

SPE Canada Heavy Oil Conference, 2020
Abstract Understanding how SAGD works is important as most of the in-situ production of bitumen in Alberta is using SAGD technology. A key parameter in simulation-based SAGD performance prediction is the residual oil saturation, which usually in SAGD simulations is a fixed number based on typical two-phase end-point relative permeability

Chemical Tracers for the Offshore Determination of Residual Oil Saturation

Offshore Technology Conference-Asia, 2014
Residual oil saturation (Sor) is a particularly important parameter for depleted oilfields as it gives an indication to the potential effectiveness of an enhanced oil recovery program. The single-well chemical tracer test using reactive ester tracers such as ethyl acetate has been used extensively to accurately determine Sor. However, these tracers are

CO2 EOR and Associated Storage in Residual Oil Zones: Modelling the Evolution and Significance of Oil Saturation in Residual Oil Zones

SSRN Electronic Journal, 2018
Residual oil zones (ROZs) are reservoirs in which oil is largely at levels of residual saturation. Such reservoirs cannot be produced by conventional production techniques. ROZs in carbonate reservoirs in the Permian Basin of West Texas were initially interpreted (from wireline logs), as being productive oil zones.
