We are committed to increasing hydrocarbon reserves through innovative approaches in petrophysical analysis. Petrophysical Log Analysis Software Powerful, multi-well, petrophysical analysis and mapping LMKR GeoGraphix ® PRIZM ™ log analysis software is the ideal tool for performing full reservoir characterization on well datasets of all sizes and complexity, from basic individual wells to multi-well, multi-zone projects. It would give you much better control over the depth intervals. CALIPER III. Petrophysics (from the Greek πέτρα, petra, "rock" and φύσις, physis, "nature") is the study of physical and chemical rock properties and their interactions with fluids. The Shaly Sand Advisor (SSA) is an exciting log interpretation tool co-developed by The Logic Group and Dr. Well log data helps to identify permeable zones and productive zones for hydrocarbon. Data modeling developed for log analysis, but broadly applicable, $45 plus $6 shipping : PEPAC3 Log analysis package, 20 spreadsheets-Gulf Publishing Company member, $220. Enhance Oil & Gas Exploration with Data-Driven Geophysical and Petrophysical Models demonstrates a new approach to geophysics and petrophysics data analysis using the latest methods drawn from Big Data. anisotropic Annual Logging Symposium application Archie average Baker Atlas bed boundaries bed thickness bed-type borehole image log bulk density button Chapter color computed conductivity conventional log analysis convolution models core photographs core plugs cutoff deconvolution defined definition depth Digital core images distribution EBI. Links to Petrophysical consultants: Ron Zittel www. To understand the petrophysical properties of an unconventional reservoir, well log data are used to investigate the rock properties of the shales in the areas of interest. This course practically elaborates how different shale petrophysical parameters such as porosity, fluid saturation, and adsorbed gas, which are essential for volumetric analysis of shale reservoirs, can be estimated using well-log data. The course is intended for entry-level geoscientists and engineers, as well as for more experienced staff and technical assistants needing a better understanding of the principles of log interpretation and/or to update themselves on the range of log measurements and techniques now available to them. Accurate determination of petrophysical properties for both the reservoir and its fluid contents is the basis of relevant formation evaluation. We are committed to increasing hydrocarbon reserves through innovative approaches in petrophysical analysis. Petrophysical analysis began with lithology identification where it was established from well logs assessments that the study area is characterized by sand-. Start your free trial. Uncertainties from well log and petrophysical interpretations should be analyzed, quantified and explicitly. The figure below shows a log display with the updated petrophysical interpretation The figure below shows a full functions work-flow interpretation for a clay mineral solver The figure below shows the log display of the clay mineral solver from the above work-flow. modern log analysis company pty ltd. JLog is designed for those who do log analysis from time to time on unconventional reservoirs and conventional reservoirs with one or many zones that have all the same characteristics such as Rw, Rmf, GRclean and so on. Water Saturation 5. Log Data Processing Includes Log Digitizing, Las or ASCII data import and generally any type of data posting relevant to the HDS Log Analysis Program. Well log, core analysis , formation pressure and test data are integrated in an iterative evaluation to provide an optimized interpretation of reservoir properties and ranges. This one-day seminar will consist of a series of themed talks, on the essentials of core analysis for formation evaluation, each lasting around 30 minutes with five minutes for questions. included tuning well log interpretations through integration of core, water chemistry and production analysis data to help identify bypassed pay zones; and improved understanding of the spatial variability of various petrophysical parameters such as porosity and permeability.
