Description

Various geologic informations from a well bore are very important and the key for petroleum explorations. Different kinds of approaches were made for setting up a database system for the geologic data from a well. Those are subdivided by two types; a domestic and an international types, which have independently been used due to the differences on quality, quantity and usage of the information. The international database is characterized by the large number of referenced wells, which contents are limited only to basic informations. On the contrary, the domestic one consists of full of informations which number of wells is limited. In the recent years, as explorations in overseas have become active, we can obtain the data in detail like the domestic style for the wells in the foreign countries. Therefore, it becomes necessary to develop an integrated system which can handle both types of database.<BR>A new database system, named“WORLDWELL”, is developed to cover demands described above.“WORLDWELL”is a relational database, referenced by the file of memory address so that we canminimize the time to search items and can save a memory space only for the existing data. It is also easyto add a new category of items into the system. Thus“WORLDWELL”has a structure of high flexibility. Another merit of this integration of domestic and international formats is to share application programs for both datasets. In addition, an interactive feature on the screen makes system user-friendly.<BR>The database itself should evolve from the one merely arranging and storing the measured data to the highest version including the unmeasurable data that affect the exploration strategies for the area.“WORLDWELL”is a first step toward such“a strategic data base”.
