LONG BEACH, California – The drilling, logging and other oilfield equipment of today bears a resemblance to its earliest predecessors. But the volume of data acquired when drilling a well has grown substantially over the years. This volume might leave scientists and engineers wondering what data they have acquired unless they have a photographic memory: the number of well-log curves and parameters exceeds 50,000 and grows by approximately 1,000 curves yearly.
A real-time delivery mechanism improves the acquisition, processing and interpretation workflows by supplying log-curve descriptions and other information via the Web.
Obtaining, managing and interpreting detailed petrotechnical data is an enormous challenge for scientists and engineers. Geologist Eric Hatleberg of Schlumberger described this challenge in a presentation at the American Association of Petroleum Geologists (AAPG) Annual Convention here in Long Beach. "Individual logs may comprise several hundred curves," Hatleberg explained. "New measurements greatly improve subsurface characterization, but using these new logging capabilities depends on obtaining and understanding the associated log-curve mnemonics."
Hatleberg and colleagues from Schlumberger developed an interactive delivery mechanism that is fast, accurate and readily updated compared with traditional hard-copy sources for log mnemonics and vital related information. This Web database of log mnemonics enhances understanding of well log data by also delivering log-curve descriptions, log-property-measurement definitions, mineral properties and relevant units of measure used by the service company.
"Web delivery of petrotechnical data and other information offers distinct advantages over other delivery methods: worldwide, unlimited access on demand; evergreen content; and robust query mechanisms to deliver specific information," Hatleberg added. "Readers can obtain additional information by navigating hyperlinks."
