    Introduction to Shale Reservoirs

    With the increasing global demand for clean hydrocarbons, the E&P companies are in search of unconventional resources such as shale gas and oil. They have very specific characteristics, such as complex mineralogy, lateral and vertical heterogeneity as well as anisotropy. These characteristics require detailed characterization and exploitation technologies.

    The class provides attendees with focused instruction on the geological, geophysical and petrophysical attributes of shale reservoirs, including the origin and accumulation of natural gas and liquids. Participants will be exposed to the methods and workflows for identifying and characterizing shale reservoirs. They will build on this foundation to learn about the engineering aspects of shale hydrocarbons exploitation. Participants will gain an understanding of methods and workflows for developing shale hydrocarbons resources including horizontal well architecture & placement, completions, hydraulic fracturing and production.

    Day 1

    Exploring Shale Reservoirs

    Geologic Considerations: regional (or basin-wide) structural influences and tectonic considerations and local stratigraphy.

    Exploration Considerations: Reconnaissance methods; objectives and tasks involved in the exploration study; screening and ranking prospects; importance of fractures; use of seismic in the evaluation of shale reservoirs; role of geomechanics; use of basin modeling and petroleum systems analysis; risk analysis and pilot projects

    Geochemical - Total Organic Carbon & Thermal Maturity.

    Day 2

    Appraising Shale Reservoirs

    Formation Evaluation: Wireline Logging; Borehole Imaging; Micro-Seismic Analysis; Wireline formation testing. Using log measurements for determination of mineralogy; porosity (total porosity vs. effective porosity); permeability; free and total gas quantification; adsorbed hydrocarbons quantification; saturation and shale gas integrated with cores. Understanding rock heterogeneity

    Geomechanics - Paleo Stress; Modern Stress; Near borehole Stress and Wellbore Failure; Mechanical Earth Model (MEM); Thickness, Depth and Pressure; Hydrocarbons Storage Capacity.
