Oil and gas (GAS) is a non-renewable natural resources (non-renewable), trapped in reservoir rocks and are formed through geological processes. The business activities of oil and gas field itself is an expensive investment and high risk. To reduce the risk of the oil and gas exploration activities needs to be done a number of phases of activity with various methods and technologies, ranging from the most basic and inexpensive to expensive in order to sort out potential areas that are still worthy of further development.
Investment in Oil and Gas activities will result in the addition of the volume and type of data, it would require an integrated data management system. Data integration a good oil and gas reserves will lead to efficiency in terms of both cost and time. Geographic Information Systems (GIS) is a tool serves to enhance the optimization of data related to the spatial or geographic coordinates either manually or automatically by a computer (digital).
Management of information-based oil and gas potential of GIS data will assist the government in policy making oil and gas fields and will also greatly help the community and investor oil and gas industry and its supporters in deciding. Results SIG communicative, informative and attractive will be more useful and capable as the basis for all parties to speed up the execution of his duty.
Manage the activities of the said data to produce;
Integrated oil and gas data
Data management of a comprehensive oil and gas fields
Optimization of each data field of oil and gas
Cost and time efficiencies in the acquisition of information.
With these results are expected to help decision makers and policy makers in taking decisions on oil and gas sector, will also facilitate and assist investors in their investment.
In general, the scope of the research was conducted pegumpulan secondary data and the use of technology for the preparation of the Information System Data Information System GeografisManajemen Gas Central Sumatra. GIS technology is used to explain and describe the aspects directly related to oil and gas exploration and production activities, the identification of baseline data related to upstream oil and gas activities.
The methods used in these activities using secondary data anlisis The discovery of reserves of Oil and Gas Activity Report FY 2002 and 2003. The outline of the implementation of such work in the flow chart (see GambarBagan flow).
Based on the data and conducted an inventory of existing information and identification. At this stage of data processing (rectification and digitization) inclusion of spatial data and tabular data all the coverage has not been organized. After all the spatial data information tabularnya equipped with data, all data are organized in thematic coverage as well as the circuit layer is spatially organized by map sheet. Each thematic layer is given the coordinates UTM (Universal Transverse Mercator). These coordinate systems provide a useful projection of the location to ensure a known relationship between the location on the map with the actual location on earth.
Other processes in the database management is the incorporation of adjacent maps, this process is useful to minimize the volume of space or space used by the coverage and provide more integrated information.
Development of Spatial Database
To develop GIS Oil and Gas Data Management needed a system that can store and display the results of the mapping data in the form of land information and testimony. Land information is very important in the management plan area and can deliver information to users about what to do with the land to achieve a particular goal.
SIG is one form of current information technology is used to optimize data on potential oil and gas in Central Sumatra, which is obtained by many different parties with different purposes. Capabilities can be used to compile a data base and integrate spatial data with attribute data, so the system can answer both questions of spatial and non spatial.
Strategy and planning phase of the system, using a soft-system approach to structured system development and de-velopment with emphasis padaidentifikasi problem (system) danperencanaan system.
System analysis phase, using a structured approach to system development to conduct a needs analysis that will be the prerequisite information data base to be constructed and functional analysis of the automation system will do
Data Storage File
In the planning stages of a system that performed structured data file or file structure based on the directories, sub directories, and layer / file. File directory organized by grouping according to the needs of others for Data Management of Oil and Gas Potential in Central Sumatra. Directory are:, blocks, oil and gas fields, subsurface data, and other supporting data (history of the field, production dancadangan). Each sub-directory directory dibagimenjadi, namely: raster, and gridding.
Raster: The file of map data and regional geological map of Sumatra Island
Gridding: grid system used (UTM grid system)
Infrastructure: The infrastructure, oil and gas block boundaries.
Oil and Gas Field: The oil and gas file, such as wells, oil field gas.
Data below the surface: The file of structure contour, isopach, log data.
Other:
Groups of data files that do not include the file above, or involving more than one directory, such as administrative region (city and district, the city as a center for oil and gas activities).
In the following figures show the results of the preparation of data files in the form of prints (print out) web interface.
Conclusion
Management functions related to oil and gas data management, particularly related to the discovery of reserves Block and Block Rokan CPP Phase I (Central Sumatra) are grouped into 7P, as follows:
Planning (Planning)
Organizing (Organising)
Storage (Saving)
Control and Supervision (Control-ling)
Communicating (Communicating)
Monitoring (Monitoring)
Integration (Integrating)
Inventory including field data collected oil and gas field located in the Central Sumatra Basin Block CPP. From the results of data collection there are 27 oil fields and two gas fields. While the report identified the Phase I Rokan Block 50 field.
In regard to the exploitation field are grouped into data per field. Groups of data from one field (field) are united in a single layer data (layer) so as to facilitate information materials used. In the chosen database management software (software) MapInfo, using the display data in HTML format (Hy per Text Markup Language).
File directory is based on the grouping for the calculation of oil and gas development strategy. Directory are: infrastructure, oil and gas facilities, space, and others.
