Abstract

GIS system in PETRONAS, known as PIRI GIS, was launched in January 2006 and has been successfully utilized for planning of various work scope in E&P industry. All decisions taken must be accurate without jeopardizing the final product or results. Resources provided need to be wisely maintained with respect to time and cost. Drilling at wrong locations or platform anchors hitting pipelines are some examples of improper data utilization. Data without geodetic description are commonly encountered not only during 70’s, 80’s, and 90’s but even today. Confusions in applying correct geodetic parameter, or even a case of incorrect conversions or transformations, could lead to irreversible consequences. Incorrect application of datum, spheroid and projection could shift intended locations up to 400 metres off. This geomatic application is even more critical as PETRONAS expands its activities abroad and involved with new datasets and coordinate systems. Knowledge and understanding of geodetic parameter is therefore crucial to ensure data integrity, hence the role of Geomatics discipline to alleviate E&P GIS to some level of standard. It is not limited only in ensuring data integrity but also establishing procedures and standards in spatial data management in PETRONAS.
