Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 10 The Earth’s Heat -2 Total heat flow observed on the Earth’s surface (& T distribution within it) is due to: ● Release of heat due to the cooling of the Earth ● Heat produced by radioactivity (amount of radioactive elements present in rocks releases enough heat to account for ~60% of total heat flow for continental crust) Prof. Dr. G. Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 11 The Earth’s Heat -3 ● Earth’s cooling process is very slow ● Temperature of mantle has decreased by 300-350°C in 3 billion years, remaining at ~4000°C at its base ● 99% of Earth is hotter than 10000C ● 99% of the 1% is hotter than 1000C (Geothermal Education Office) Prof. Dr. G.

Magma . Hot Dry rock (HDR) & Enhanced Geothermal Systems (EGS) Prof. Dr. G. Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 19 Vapour-Dominated Most exploited fields contain water at high P & T>100 oC. When this water is brought to surface, P is reduced and a mixture of saturated steam & water is generated. There are only few geothermal fields producing superheated steam with no associated fluids (dry steam fields). (Gupta & Roy, 2007 ) Prof. Dr. G. Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 20 Hot Water Differ from vapour-dominated fields in that they are characterised by liquid water being the continuous fluid phase. Typically, 60 oC<T<100 oC at depths of 1500 to 3000 m. (Gupta & Roy, 2007 ) Prof. Dr. G. Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 21 Geo-pressured Typically form in a basin in which very rapid filling with sediments takes place, resulting in higher than normal pressure of the hydrothermal water. Often saturated with methane. First identified in the deep sedimentary layers underneath the Gulf of Mexico. Wells flow pressurised to the surface. Water T is 90-200°C. (Gupta & Roy, 2007 ; Texas Renewable Energy Resource Assessment, 2009) Prof. Dr. G. Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 22 Magma Magma is the ultimate source of all high-temperature geothermal resources. Typically, magma crystallizes to form igneous rocks at temperatures varying from 600 to 1400 oC. Magma has been encountered in situ 3 times during drilling projects—twice in Iceland, and once in Hawaii. However, up to now, the necessary technology has not been developed to recover heat energy from magma. (Gupta & Roy, 2007 ) Prof. Dr. G. Falcone Institute of Petroleum Engineering Geothermal Engineering: Fundamentals & Synergies with Petroleum Engineering 23 Hot Dry Rock (HDR) Hydrothermal resources restricted to countries with favourable geological conditions (i.e. plate boundaries). HDR resources exist where the heat is stored in hot & poorly permeable rocks at shallow depths within the Earth’s crust, without fluid availability to store or transport the heat. HDR is the new frontier of geothermal energy and possibly the area closest to petroleum exploitation Prof. Dr. G.

  • Deep Borehole Placement of Radioactive Wastes a Feasibility Study
    DEEP BOREHOLE PLACEMENT OF RADIOACTIVE WASTES A FEASIBILITY STUDY Bernt S. Aadnøy & Maurice B. Dusseault Executive Summary Deep Borehole Placement (DBP) of modest amounts of high-level radioactive wastes from a research reactor is a viable option for Norway. The proposed approach is an array of large- diameter (600-750 mm) boreholes drilled at a slight inclination, 10° from vertical and outward from a central surface working site, to space 400-600 mm diameter waste canisters far apart to avoid any interactions such as significant thermal impacts on the rock mass. We believe a depth of 1 km, with waste canisters limited to the bottom 200-300 m, will provide adequate security and isolation indefinitely, provided the site is fully qualified and meets a set of geological and social criteria that will be more clearly defined during planning. The DBP design is flexible and modular: holes can be deeper, more or less widely spaced, at lesser inclinations, and so on. This modularity and flexibility allow the principles of Adaptive Management to be used throughout the site selection, development, and isolation process to achieve the desired goals. A DBP repository will be in a highly competent, low-porosity and low-permeability rock mass such as a granitoid body (crystalline rock), a dense non-reactive shale (chloritic or illitic), or a tight sandstone. The rock matrix should be close to impermeable, and the natural fractures and bedding planes tight and widely spaced. For boreholes, we recommend avoiding any substance of questionable long-term geochemical stability; hence, we recommend that surface casings (to 200 m) be reinforced polymer rather than steel, and that the casing is sustained in the rock mass with an agent other than standard cement.

P. Ivakhnenko Department of Petroleum Engineering, Kazakh-British Technical University, 59 Tolebi Str. Almaty, Kazakhstan ([email protected]; [email protected]/Fax: +7 727 2720487) Potential applications of magnetic techniques and methods in petroleum engineering and petrophysics (Ivakhnenko, 1999, 2006; Ivakhnenko & Potter, 2004) reveal their vast advantages for the petroleum reser- voir characterisation and formation evaluation. In this work author proposes for the first time developed systematic methods of the Magnetic Analysis of Core Cleaning (MACC) and Magnetic Analysis of Fines Migration (MAFM) for characterisation of reservoir core cleaning and modelling estimations of fines migration for the petroleum reservoir formations. Using example of the one oil field we demonstrate results in application of these methods on the reservoir samples. Petroleum reservoir cores samples have been collected within reservoir using routine technique of reservoir sampling and preservation for PVT analysis. Immediately before the MACC and MAFM studies samples have been exposed to atmospheric air for a few days. The selected samples have been in detailed way characterised after fluid cleaning and core flooding by their mineralogical compositions and petrophysical parameters. Mineralogical composition has been estimated utilizing XRD techniques. The petrophysical parameters, such as permeability and porosity have been measured on the basis of total core analysis. The results demonstrate effectiveness and importance of the MACC and MAFM methods for the routine core analysis (RCAL) and the special core analysis (SCAL) in the reservoir characterisation, core flooding and formation damage analysis.

(Signature) Department of Civil Engineering The University of British Columbia Vancouver, Canada Date - A?R L 9 L DE-6 (2188) Abstract Prediction of stresses, deformations and fluid flow in oil sand layers are important in the design of an oil recovery process. In this study, an analytical formulation is developed to predict these responses, and implemented in both 2-dimensional and 3-dimensional finite element programs. Modelling of the deformation behaviour of the oil sand skeleton and modelling of the three-phase pore fluid behaviour are the key issues in developing the analytical procedure. The dilative nature of the dense oil sand matrix, stress paths that involve decrease in mean normal stress under constant shear stress, and loading-unloading sequences are some of the important aspects to be considered in modelling the stress-strain behaviour of the sand skeleton.

  • Model Petroleum Engineering Curriculum
    The SPE Model Petroleum Engineering Curriculum – What it is and what it isn’t The model petroleum engineering curriculum is intended as an aid to universities worldwide that want to start new petroleum engineering programs. It is not intended to be a “standard” curriculum, in that no petroleum engineering curriculum would have all of the course listed here. Any petroleum engineering curriculum should educate students in fundamental mathematics and science, humanities and liberal arts, engineering science, and the foundational course in petroleum engineering. Most curricula will include some more specialized petroleum engineering courses, like those listed in the model curriculum as petroleum engineering electives. No Bachelor’s of Science level degree program could include all of the courses shown in the elective list. The SPE model curriculum includes all of the educational areas needed to create a specific petroleum engineering curriculum. Every petroleum engineering curriculum in the world is unique, none are exactly the same. Many countries or regions have course requirements that do not appear anywhere else in the world. In the United States, there are significant variations in curricula, with some programs having emphases on particular areas of petroleum engineering that are different from other programs. This model curriculum can be used to construct a unique degree program for new programs, with the particular courses included based on the particular needs of that university, or that country.

    UNIVERSITY OF CALGARY Characterization of Oil Sands Tailings Using Low Field Nuclear Magnetic Resonance (NMR) Technique by Sandra Carolina Motta Cabrera A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF CHEMICAL AND PETROLEUM ENGINEERING CALGARY, ALBERTA SEPTEMBER, 2008 © Sandra Carolina Motta Cabrera 2008 ISBN: 978-0-494-44621-8 Dedication Gracias a ti por prestarme siempre tus maravillosos lentes rosados Gracias a ti por seguir queriendo estar Gracias a ti por estar siempre en mis más lindos recuerdos Gracias a ti por ser mi par mejorado Gracias a ti por mostrarme tu lado amoroso Gracias a ti por enseñarme que siempre puedo aprender Gracias a ti por ser mis hermosas alas Gracias a ti por seguir a mi lado entendiendo amaneceres y atardeceres Abstract The oil sands mining and extraction processes in Canada produce large volumes of tailings that are a mixture of mainly water, clay, sand, chemicals and bitumen. This mixture is transported to tailings ponds, where gravity segregation occurs. During this process, a stable suspension called mature fine tailings (MFT) is formed, which requires many years to fully consolidate. Therefore, land reclamation and water recirculation become significant environmental issues. For this reason, it is important to understand the tailings content and their settling properties. This study uses the low field Nuclear Magnetic Resonance (NMR) technique to estimate the composition of tailings samples, through a bimodal compositional detection method. Tailings settling characteristics were also studied in the absence and presence of the typical chemical substances used in the industry to accelerate settling.
