Beating the Exploration Schedule With Integrated Data Interpretation

Oil companies have made great strides in improving the success rate of exploration and production, mainly by using seismic data to guide well placement. But data gathering and interpretation do not stop here. Once a well is spudded, the company commits considerable resources to gather more data such as mud logs, cores, measurements-while-drilling (MWD) information and wireline logs. This creates a huge volme of data - often at different scales and qualities - that must be efficiently handled to ensure maximum return on the exploration investment. 

Communications hardware already allows large volumes of information to be moved rapidly from one computer to another  even from remote locations. And data management and universal data standards are gradually being introduced throughout the industry to facilitate data access.

To take full advantage of this new environment, however, geoscientist need their interpretation applications integrated into a common system that allows data sharing.

Until recently, no attempt was made to standarize the data format used by interpretation software packages, which meant that they could not communicate with each other or use a common database. More time was spent on converting and loading data than on interpretation. Applicatons often ran in series rather than parallel, introducing further delays. This resulted in drilling or completion decisions being made using incomplete answers while full interpretations took weeks or months.
