Recent Enhancements · 13,443 wells were added to the database in 2013. Of these 8,039 wells were related to current industry activity and 5,404 wells were historical wells newly acquired following successful liaison with governments, country correspondents and/or operators · In addition to wells entered, 55,851 wells were updated with newly released or newly acquired details further improving the completeness, correctness, consistency and currency of our data. In fact 8% of the wells database has been improved this past year. · More than 40 Quality Projects and 1 Quality Goal were completed throughout 2013. Projects included: 79 INTERNATIONAL IHS | www.ihs.com INTERNATIONAL WELLS DATABASE Our global coverage is second to none and there are currently more than 725,000 wells in the database. All currently active wells are maintained and regularly updated as soon as new data becomes available. Historical information is also actively researched to ensure a continually evolving dataset. Our well records are comprehensively populated with not only header attributes such as surface location, spud and completion dates, well type and the operators and partners that drilled the well but also more detailed up to date attributes including: »» Drilling history including drilled depths versus time, casing points, stuck pipe problems, sidetracks with kick off depths »» Objective formation and lithology »» TD and TVD bottom hole formation and lithology »» Formation tops with geological age and lithology »» Tested intervals with geological formation and lithology, choke sizes, flow rates and pressures Raw data is received in varying formats and multiple languages from around the globe. In many countries very little well information is available in the public domain and in these areas we rely on our extensive network of in-country correspondents and excellent relationships with government ministries developed through the expertise of our experienced Regional teams. We have a robust quality program including in-built data validation processes, quality goals, quality projects and we are continually striving to identify new data sources to increase our overall coverage and update our existing information. Our well data is used by a multitude of industry professionals for numerous purposes including research and appraisal of well locations worldwide, reviewing current and historical drilling results, analyzing drilling success ratios, mapping well tops and evaluating test results. »»Adding test results »»Entering tops »»Entering/improving objective and bottom hole formations »»Improving spatial integrity »»Entering CBM wells »»Entering missing development wells »»Improving header data · Our Quality Goal performed on the Wells Database has focused on improving the spatial consistency between sidetracks and their predecessor wells.
