The article discusses the formation of a geological model from a database derived from geological information technology. It adds that use of the database, providing simultaneous operations of all applications without re-mastering and reformatting of data, enables the user to form a comprehensive set of controls for the geophysical data. The controls, the paper indicates, could be integrated in a subsequent analysis used for interpreting both geological and geophysical data, thus providing a single technological chain to perform most processes. Expanding on this subject, the document states that it has become necessary to develop and use the integrated Open Works database to ensure the efficient aggregation of traditional methods of prospecting and exploration using modern computer technology. Open Works’ initial set of data includes information contained in the ’Matters Wells’ daily geological reports, drilling reports, and research reports. The database is described as a unique identification source, designed to produce a personalized connection to any well. At this stage, the document notes that the records of any information incorporated in the Open Works database also appear in the Well-Master table (citing basic information on the wells). The petro-physical well data contained in the Open Works – including basic information about the selection of the core hole (geological age, type, condition and depth of core sampling) – has been derived from geological input instructions. Other relevant data have been recorded in a series of tables: Well-Core (information about the wells’ coring), Well-Core-Formation (list of all stratigraphic units represented by this core) and Well-Core-Sample (analysis of the core sample).
