ABSTRACT: Clean sand/silt values of permeability and water saturation in the Athabasca oil sands are important inputs to resource volume calculations, pay and thief zone identification, and geomodels for flow simulation to rank projects and make development decisions. Often a challenge to estimate accurately, these two petrophysical properties are particularly troublesome in oil sands owing to problems in obtaining sufficient, reliable, and inexpensive lab measurements to use as ground truths for log analysis. Typical absolute permeability and formation factor tests often yield questionable and unreliable results due to the unconsolidated nature of the sediments and the occurrence of the oil as bitumen, which causes sample deformation in handling and testing (Brabant and Al-Adani, 2014).
A solution to achieving reasonably accurate and reliable results at no extra cost has been found through the adaptation of established equations developed for unconsolidated material, which have been tested with new, theoretical, pore geometry models and published, lab measured data to ensure integrity as described here. These equations use reliable and accurate data that for oil sands are widely available, bypassing troublesome and expensive techniques and providing extensive spatial coverage to improve reservoir characterization. Application to oil sands has shown good agreement with measured data and explains why significant differences in reservoir performance occur between recovery project areas, as well as validating the possibility of very high permeability values. The new methods provide superior clean sand/silt values for use in mini-models (Etris et al., 2012) and micro-models (Manchuk et al., 2015) to scale-up values for reservoir models.
BIOGRAPHY: Ned Etris is an experienced team leader and science advisor for natural resources evaluation, specializing in reservoir characterization through petrophysics, geostatistics, and geomodeling. Ned got his MSc and PhD in quantitative geology from the University of South Carolina where he used data science to investigate sedimentological controls on petrophysical properties. He has worked for over 20 years in the Calgary oil-patch as a professional geologist integrating geoscience data and disciplines with engineering for production optimization of conventional and unconventional reservoirs worldwide. Most recently, Ned was Director of Geomodeling and Petrophysics for Suncor Energy where he advanced the characterization methods for both thermal and mining oil sands assets. This is also where he initiated the work that he is presenting on today to meet the needs of thermal recovery operations.

The Canadian Well Logging Society (CWLS) announces yearly awards for engineering and earth sciences undergraduate and graduate students in Canada. The purpose of these awards is to raise interest and awareness of careers in Petrophysics and Formation Evaluation. Formation Evaluation and Petrophysics are the studies of rocks and their fluid properties as they pertain to the oil and gas industry.
This year the The Winston Karel CWLS Student Award will be funded by Lois Decker, wife of Winston Karel. Winston Karel was a long time CWLS member and friend to the community who passed away on July 1st, 2015.
Best Student Thesis wins $1000
Best Student Abstract wins $500
Submissions should critically examine some aspects of well logging, formation evaluation or petrophysics and should be submitted to the CWLS in their final year of study. The final thesis can be submitted at any time in the year of graduation. Submission deadline is October 31, 2019 and the CWLS will select award winners by Mid November of this year.
The winners will be invited to the December luncheon to receive the awards and to make a presentation at a CWLS lunch meeting in Calgary later in the year.
Student Award Eligibility Criteria: Candidates must be registered full-time at a Canadian university. A student’s financial need will be considered.
Student Award Application Procedure:
Completed application forms must be received before October 31, 2019. Application forms can be downloaded below:
