Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The prediction of physical attributes for a proposed well in well drilling applications is a time-intensive and error-prone process, requiring extensive re-calculations whenever criteria change, due to the non-intuitive nature of correlating formation tops and selecting physical attributes from offset wells.
Innovation Solution
A user interface is provided that displays offset and proposed formation top graphs, allows mapping and normalization of physical attribute data, and determines physical attributes for the proposed well by selecting portions of the normalized graph, using a system with a processor, memory, and input device to facilitate efficient prediction.
