This course is a 5 days course, this course includes exhaustive case studies and exercisesRoutine Core Analysis This course/training aims to disseminate information to help understand what we do in a Routine Core Analysis Laboratory, how the data is generated and how to interpret the results. However, more importantly, it will help you understand why core analysis should be done, how it can help client, how to compile a meaningful and representative study, including obtaining representative cores in the field and how to stay within budget and time constraints. It will also give an overview of how to handle the core in the field and laboratory to avoid damage to the precious core and there by minimizing the error in the data obtained. The course covers the following topics: CORING – Planning the Core Program, Different Coring Tools and Core Types, with a special section on Unconsolidated Cores and the Effects of Coring. MUD SYSTEMS – The type and properties of the mud systems used should be considered when planning the coring operation. In some cases mud systems are modified to meet the specific objectives of the coring program. This part is only as an introduction to remind the reader of the implications of mud system selection. More details are presented in the relevant parts of the Special Core Analysis and Formation Damage seminars. WELLSITE, GAMMA & SATURATION – Covers wellsite handling/services and analysis including gamma and probe permeability followed by shipping and receipt of the core at the laboratory. Detail is given to handling and analysis for Saturation data, oil saturations, water saturations and fluid invasion/tracer analyses. SAMPLE PREPARATION – Includes sample drilling, preservation, cleaning and drying, plugs and whole cores. LAB ANALYSIS – Air Permeability, Porosity, Grain Density and Klinkenberg Permeability, ambient and overburden; includes data interpretation, correction, QC/QA techniques. PHOTOGRAPHY – Photography provides a useful long-term record of the core, various formats are available and quality control is vital. VALUE & UNCERTAINTY – Core Data valuation, Risk Reduction and Uncertainty. Special Core Analysis The course aims to disseminate information to help understand what we do in a Special Core Analysis Laboratory, how the data is generated and how to interpret the results. The course will encompass analysis planning, sampling, sample preparation and sample selection based on the results of the RCA and petrophysics. More importantly, it will help you understand why Special Core analysis should be used, how it can help you, how to compile a meaningful and representative study, and how to optimize the study to stay within budget and time constraints. SCAL STUDY PLANNING – In this section we will look at some aspects that should be considered prior to initiating a SCAL study, i.e. useful steps to develop as a planning stage of a quality study. SCAL SAMPLING – We will look at the options for WHEN & HOW SCA samples, usually called PLUGS are taken or cut (drilled) from the host core. If samples are taken that are not representative of the reservoir/formation then the results will also not be representative. This is clearly a waste of money, time and effort in performing the SCAL study. However imagine if these unrepresentative data are subsequently used!! The sampling protocol must be established prior to sampling. SCAL SAMPLE PREPARATION – There are a number of issues to address at this early stage of the analysis cycle, as the procedures used to obtain, extract and dry the samples can have a considerable bearing on the quality and reliability of produced data. This comment is particularly relevant when samples are being taken and prepared for special core analysis work, where the potential impact of unrepresentative data is magnified. SCAL SAMPLE SELECTION – From our pool of available samples we need to select a final set for analysis. Simply the samples need to be homogeneous, undamaged and representative. This final quality is derived through careful evaluation of the sample compared with reservoir/formation/facies/unit characterization, including FZI/RQI. PRE-STUDY – In this section we will look at a relatively new concept of Pre-Study. In essence a small study to define certain project specific factors prior to performing the main study, confident in the knowledge that these factors have been correctly incorporated. This includes Petrological evaluation of clays and minerals. Each of the subsequent sections looks at the actual SCAL tests in the following formats: Introduction; Background; Why perform these Analyses; Type of Analyses; Lab Results and Data Processing and Quality Control:
