Conclusions

Geographic Information System and Remote Sensing has become a widely accepted tool in all fields of life and particularly in hydrocarbon exploration and exploitation. In building a GIS database for comprehensive analysis, all avenues of data collection should be perused including literature survey, public and private organizations and computer networks. The integration of remote sensing with GIS provides a greater understanding by combining remotely acquired spectral information with other data including physiographical, geological, geophysical, hydrogeological, geochemical and positional data. The use of GIS in natural resources evaluation has recently expanded with increasing emphasis in surface and subsurface applications. GIS and Remote Sensing helps in monitoring and managing earth resources accurately and reliably at a cost-effective and short turnaround time, and thus, led to the acceptance of this as technology by the scientific community.

Implementation of GIS in DGPC resulted in data normalization, control redundancy and enforced data integrity, timely access to information, cost effective solution and self-revenue generating model, ensures data validation and security, easy data management and maintenance, on-line available E&P data, easy data duplication and format conversion, easy generation of interactive and fully customized maps, provided updated data and maps, provided standard base map for upstream petroleum activities. Currently, the industry has numerous powerful geological and geophysical planning, evaluation, processing, analysis, and interpretation tools. These requirements can be effectively addressed with an effective implementation of GIS and Remote sensing technology. The net gains are improved efficiency and quality through effective information management, analysis, and dissemination.
