Modeling Static of Petrophysical Properties with Well Loggin Analysis and Geostatistics

The description of the distribution of porosity in a reservoir is a very important aspect on reservoir engineer. It has a direct impact on economic decisions in the exploration and production projects. A statistical technique developed to apply to the problems of Earth Sciences is the Geostatistics. This technique study the spatial continuity of the attributes of a reservoir, in order to provide characterizations of heterogeneous reservoirs, using many estimation methods. With the information obtained from the petrophysical evaluation, a litho-correlation of the well with the interested zone. Making a model 3-D using geostatistical techniques Variography, estimate and simulation of each of the petrophysical properties from the evaluation of the well logging. In this paper make a methodology for static modeling of reservoir from well loggings. It is noteworthy that as the specialized software (Techlog, Petrel and SGeMS) . The first of the petrophysical evaluation, the second of correlation with seismic data and last for geostatistics method. With all that bucket each petrophysical property is obtained. The results collectively contribute to the quantification of the reservation.
