WDJD-4A: Automating Optimal Survey Geometry Through AI-Powered Forward Modeling and Adaptive Planning

The quality of a geophysical inversion is fundamentally limited by the quality of the survey design. A poorly designed acquisition grid can obscure critical targets, waste field time, and yield ambiguous results regardless of the instrument's precision. The WDJD-4A addresses this foundational challenge as a Cognitive Survey Designer, a system that leverages artificial intelligence and automated forward modeling to generate optimal, target-specific survey plans. It moves beyond static, rule-of-thumb survey layouts to provide dynamically optimized acquisition geometries that maximize the probability of detecting and resolving specific subsurface features of interest while minimizing field effort. This capability places the power of advanced survey design expertise into the hands of every operator, ensuring that every campaign begins with a plan mathematically tailored for success.

The cognitive design process begins with the definition of the investigation objective. Using an intuitive interface, the operator specifies the target: "Map the geometry of a suspected aquifer at 50-80m depth," or "Detect and delineate narrow, steeply dipping sulfide veins." The system's AI engine then accesses a library of geological scenarios and forward models. It rapidly simulates thousands of potential survey designs—varying electrode array types, spacing, line orientations, and measurement density—and evaluates each design's theoretical ability to resolve the specified target under modeled noise conditions. The result is not a single recommended design, but a Pareto-optimal front of solutions that trade off between resolution, depth of investigation, and survey time. The operator can then select the design that best aligns with project priorities, confident that it represents a mathematically optimal approach.

This capability delivers profound operational and technical advantages. It democratizes expert-level survey design, ensuring that projects are not handicapped by the varying experience levels of field crews. It eliminates the costly guesswork of "standard" survey layouts that may be ill-suited to the unique geological context of a site. Perhaps most importantly, it enables rapid re-design in the field. If initial results reveal unexpected geology or a target at a different depth than anticipated, the operator can re-run the cognitive designer with the new information and generate an optimized infill survey plan on the spot, without returning to the office. This adaptive capability ensures that field time is always directed by the most current subsurface understanding. The WDJD-4A Cognitive Survey Designer thus transforms survey planning from a static, one-time activity into a dynamic, iterative, and intelligence-driven process, guaranteeing that the data collected is always maximally informative for the questions being asked.
