Formation Evaluation II

EART30772 Formation Evaluation II 10 Semester 2 Undergraduate Level 6 Catherine Hollis Unit coordinator Department of Earth and Environmental Sciences 1 FHEQ level (Framework for Higher Education Qualifications) ' Last part of a Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 <div> This Unit advances knowledge of the range of tools and techniques used in Formation Evaluation from Formation Evaluation I.  It outlines the theory and methods behind determination of the volume and recovery of hydrocarbons within oil and gas reservoirs, focusing on core and geophysical (wireline) logs.  Emphasis is on the geometry of pores in clastic and carbonate reservoirs and their impact on the quantification of porosity and oil in place, as well as formation damage.  The role of non-routine logging techniques in reservoir characterisation is also introduced.This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.</div>   <div> <div> <div> This Unit advances knowledge of the range of tools and techniques used in Formation Evaluation from Formation Evaluation I.  It outlines the theory and methods behind determination of the volume and recovery of hydrocarbons within oil and gas reservoirs, focusing on core and geophysical (wireline) logs.  Emphasis is on the geometry of pores in clastic and carbonate reservoirs and their impact on the quantification of porosity and oil in place, as well as formation damage.  The role of non-routine logging techniques in reservoir characterisation is also introduced.This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.</div> </div>  </div>   <div> To build on the principles of Formation Evaluation described in Formation Evaluation I (EART20432), such that students are capable of providing a robust geological and petrophysical assessment of reservoir quality and rock physical properties</div>  On the successful completion of the course, students will be able to: <ul> <li> Quantify risk, describe mitigation strategies and their impact on residual risk and uncertainty, within the context of field development</li></ul><ul> <li> Conduct a Value of Information exercise in order to justify a subsurface data collection programme</li></ul><ul> <li> Describe the different types of porosity in sandstones and carbonate rocks and their genesis, from deposition and during diagenesis</li> <li> Define the main types of clay minerals, their origin and morphology and how they might result in formation damage during production</li> <li> Describe which elements are measured by the spectral gamma ray tool and how this data can be used to refine Vshale analysis in radioactive sandstones, and determine sediment provenance</li> <li> Conduct shaley-sand analysis using Vshale and cation exchange capacity, and explain why this can increase the calculated volume of in place hydrocarbons</li> <li> Describe how borehole image logs and NMR logs work, and how they can be used for reservoir characterisation in uncored wells</li> <li> Explain how rock type and pore structure influence rock physical properties, and how this data is used to calculate porosity from acoustic data, particularly seismic data</li></ul> <ol> <li> Uncertainty, VOI, data gathering & surveillance</li> <li> Diagenetic controls on reservoir quality</li> <li> Pore systems in carbonate rocks</li> <li> Pore systems in clastic rocks</li> <li> Clay diagenesis and formation damage</li> <li> In class assessment</li> <li> Advanced lithological interpretation of wireline logs</li> <li> Special logs</li> <li> Saturation in non-Archie reservoirs</li> <li> Rock physics models</li> <li> In class assessment</li></ol>  <div> This module will be delivered as a 1 hour lecture followed by a 2 hour practical involving paper-based exercises and petrographical anlaysis.  </div>  0 Other 30% 9 Set exercise 70% Two In class sessesments (15% each)    <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td style="height: 68px;
