Well Logging, Volume 3 - Well Logging and Reservoir Evaluation

Description

This book focuses on reservoir evaluation of the main goal is the determination of the hydrocarbon volume existing in the drilled well and the discovered field. This evaluation requires the determination of several factors: the reservoir volume; the reservoir tectonic and stratigraphic settings; the presence of fractures; the reservoir mineralogical composition; the hydrocarbon volume in place and extractible; the permeability which depends on sedimentary features, fractures, dissolution and fluid type; and the production potential that is a function of the permeability and the reservoir pressure. The determination of these factors will be considerably improved using a complete logging set including images of the borehole wall and nuclear magnetic resonance data and their interpretation by a team including geologist, geophysicist, petrophysicist and reservoir engineer. The depositional environment can be precisely determined from well logging data, possibly calibrated on core data. This determination, completed by the detection of the faults crossed by the well, will allow a more precise interpretation of seismic data and consequently a better modeling of the reservoir for its economical evaluation and development.
