The CryoSEM technique, in which the sample is freeze fractured within the SEM chamber prior to observation, provided pictures in which the (frozen) bitumen clearly appears between the sand grains. No evidence of the existence of a thin connate water layer between grains and the bitumen, frequently mentioned in the literature, has been obtained.

  • High-Resolution Gamma Ray Attenuation Density Measurements on Mining Exploration Drill Cores, Including Cut Cores
    The following document is a pre-print version of: Ross P-S, Bourke A (2017) High-resolution gamma ray attenuation density measurements on mining exploration drill cores, including cut cores. J. Apl. Geophys. 136:262-268 High-resolution gamma ray attenuation density measurements on mining exploration drill cores, including cut cores Ross, P.-S.*, Bourke, A. Institut national de la recherche scientifique, centre Eau Terre Environnement, 490, rue de la Couronne, Québec (QC), G1K 9A9, Canada * Corresponding author, [email protected] Abstract Physical property measurements are increasingly important in mining exploration. For density determinations on rocks, one method applicable on exploration drill cores relies on gamma ray attenuation. This non- destructive method is ideal because each measurement takes only ten seconds, making it suitable for high- resolution logging. However calibration has been problematic. In this paper we present new empirical, site- specific correction equations for whole NQ and BQ cores. The corrections force back the gamma densities to the “true” values established by the immersion method. For the NQ core caliber, the density range extends to high values (massive pyrite, ~5 g/cm 3) and the correction is thought to be very robust. We also present additional empirical correction factors for cut cores which take into account the missing material. These “cut core correction factors”, which are not site-specific, were established by making gamma density measurements on truncated aluminum cylinders of various residual thicknesses. Finally we show two examples of application for the Abitibi Greenstone Belt in Canada. The gamma ray attenuation measurement system is part of a multi-sensor core logger which also determines magnetic susceptibility, geochemistry and mineralogy on rock cores, and performs line-scan imaging.

  • Hyperspectral Imaging for the Characterization of Athabasca Oil Sands Core
    Hyperspectral imaging for the characterization of Athabasca oil sands core by Michelle Alexandra Speta A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Earth and Atmospheric Sciences University of Alberta © Michelle Alexandra Speta, 2016 Abstract The Athabasca oil sands of northeastern Alberta, Canada, are one of the largest accumulations of crude bitumen in the world. Drill core sampling is the principal method for investigating subsurface geology in the oil sands industry. Cores are logged to record sedimentological characteristics and sub-sampled for total bitumen content (TBC) determination. However, these processes are time- and labour-intensive, and in the case of TBC analysis, destructive to the core. Hyperspectral imaging is a remote sensing technique that combines reflectance spectroscopy with digital imaging. This study investigates the application of hyperspectral imaging for the characterization of Athabasca oil sands drill core with three specific objectives: 1) spectral determination of TBC in core samples, 2) visual enhancement of sedimentological features in oil-saturated sediments, and 3) automated classification of lithological units in core imagery. Two spectral models for the determination of TBC were tested on four suites of fresh core and one suite of dry core from different locations and depths in the Athabasca deposit. The models produce greyscale images that show the spatial distribution of oil saturation at a per-pixel scale (~1 mm). For all cores and both models, spectral TBC results were highly correlated with Dean- Stark data (R2 = 0.94-0.99). The margin of error in the spectral predictions for three of the fresh cores was comparable to that of Dean-Stark analysis (±1.5 wt %).

  • 1994: Effects of Coring on Petrophysical Measurements
    EFFECTS OF CORING ON PETROPHYSICAL MEASUREMENTS. Rune M. Holt, IKU Petroleum Research and NTH Norwegian Institute of Technology, Trondheim, Norway ABSTRACT When a core sample is taken fiom great depth to the surface, it may be permanently altered by several mechanisms. This Paper focusses on possible effects of stress release on petrophysical measurables, such as porosity, permeability, acoustic velocities and compaction behaviour. The results are obtained through an experimental study, where synthetic rocks are formed under simulated in situ stress conditions, so that stress release effects can be studied in a systematic way. INTRODUCTION Core measurements provide important input data to petroleum reservoir evaluations. Uncertainties in reserve estimates and predicted production profiles may originate from uncertianties in core data. In addition to measurement errors, such uncertainty may be a result of core damage (see e.g. Santarelli and Dusseault, 199 1). By core damage we mean permanent alteration of core material so that the material is no longer representative of the rock in situ. It is important to distinguish here between core alteration, which can be repaired by reinstalling the in situ conditions, and permanent core damage. A general advice would be to perform any core measurement as close to in situ (stress, pore pressure, temperature, fluid saturation) conditions as possible. In the case of a damaged core, this does however not warrant a correct result. The focus of this Paper will be on unrepairable core damage, and where the damage is caused by a mechanical failure of the rock. We shall look briefly into mechanisms that may cause such damage, how permanent core damage may affect various petrophysical parameters, and how one may correct for or reduce such core damage.

  • Best Practices for Shale Core Handling: Transportation, Sampling and Storage for Conduction of Analyses
    Journal of Marine Science and Engineering Review Best Practices for Shale Core Handling: Transportation, Sampling and Storage for Conduction of Analyses Sudeshna Basu 1,2,*, Adrian Jones 1 and Pedram Mahzari 1 1 Department of Earth Sciences, University College London, London WC1E 6BS, UK; [email protected] (A.J.); [email protected] (P.M.) 2 Department of Chemical Engineering, University College London, London WC1E 7JE, UK * Correspondence: [email protected] Received: 9 January 2020; Accepted: 12 February 2020; Published: 20 February 2020 Abstract: Drill core shale samples are critical for palaeoenvironmental studies and potential hydrocarbon reservoirs. They need to be preserved carefully to maximise their retention of reservoir condition properties. However, they are susceptible to alteration due to cooling and depressurisation during retrieval to the surface, resulting in volume expansion and formation of desiccation and micro fractures. This leads to inconsistent measurements of different critical attributes, such as porosity and permeability. Best practices for core handling start during retrieval while extracting from the barrel, followed by correct procedures for transportation and storage. Appropriate preservation measures should be adopted depending on the objectives of the scientific investigation and core coherency, with respect to consolidation and weathering. It is particularly desirable to maintain a constant temperature of 1 to 4 ◦C and a consistent relative humidity of >75% to minimise any micro fracturing and internal moisture movement in the core. While core re-sampling, it should be ensured that there is no further core compaction, especially while using a hand corer. Keywords: shale; drill core instability; micro fracture; clay minerals 1.

  • Curatorial Care of Concrete and Rock Drill Core Samples Obtained in The
    General TSC Recommendations for Curatorial Care of Concrete and Rock Drill Core Samples September 15, 2009 Rock and Concrete Core Samples obtained in the field should be handled in a manner that meets the needs and purpose of the exploration program, site conditions and the available mode(s) of transportation. For example, freezing conditions in the winter or direct sunlight and heat in the summer may have detrimental effects on the samples for use in specific tests. Therefore, a plan that is carefully thought out (including technical and common sense issues) and implemented is needed to handle the samples from the time they are retrieved to when they are delivered to the various users of the samples. There is no set way to handle concrete and rock samples at every job site, or for every project. Therefore, a sampling plan will need to be developed for each specific investigation which will best fits the site conditions, equipment, weather, material types, intended purpose(s) of samples, and type of transportation from the drill site to both the local storage area and any final destination. General guidelines that can be helpful for developing a sampling plan can be found in the following references. 1. USBR Concrete Manual 9th edition 1992 2.

  • The Influence of Vertical Location on Hydraulic Fracture Conductivity In
    THE INFLUENCE OF VERTICAL LOCATION ON HYDRAULIC FRACTURE CONDUCTIVITY IN THE FAYETTEVILLE SHALE A Thesis by KATHRYN ELIZABETH BRIGGS Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Ding Zhu Committee Members, A. Daniel Hill Michael Pope Head of Department, A. Daniel Hill May 2014 Major Subject: Petroleum Engineering Copyright 2014 Kathryn Elizabeth Briggs ABSTRACT Hydraulic fracturing is the primary stimulation method within low permeability reservoirs, in particular shale reservoirs. Hydraulic fracturing provides a means for making shale reservoirs commercially viable by inducing and propping fracture networks allowing gas flow to the wellbore. Without a propping agent, the created fracture channels would close due to the in-situ stress and defeat the purpose of creating induced fractures. The fracture network conductivity is directly related to the well productivity; therefore, the oil and gas industry is currently trying to better understand what impacts fracture conductivity. Shale is a broad term for a fine-grained, detrital rock, composed of silts and clays, which often suggest laminar, fissile structure. This work investigates the difference between two vertical zones in the Fayetteville shale, the FL2 and FL3, by measuring laboratory fracture conductivity along an artificially induced, rough, aligned fracture. Unpropped and low concentration 30/70 mesh proppant experiments were run on samples from both zones. Parameters that were controllable, such as proppant size, concentration and type, were kept consistent between the two zones. In addition to comparing experimental fracture conductivity results, mineral composition, thin sections, and surface roughness scans were evaluated to distinguish differences between the two zones rock properties.
