Overview From acquisition to earth model, accurate velocity estimation and depth imaging provides the key to understanding the subsurface before costly drilling decisions are made. With DepthCharge, the labor intensive and interpretive nature of this processing workflow can be executed more easily, often saving days over common approaches. Built upon the industry leading SeisSpace/ProMAX processing system, DepthCharge allows processors to rapidly and iteratively analyze velocities, build a depth model, and migrate the data so that the optimal depth image can be interpreted. While velocity modeling and depth imaging have historically been both a labor and compute intensive process, the DepthCharge workflow couples simple usability designs with software architecture designed specifically for harnessing cluster multi-core CPU technology. Benefits Fast and Easy Workflows for Velocity Modeling The software is designed with ease of use as the primary consideration. The tomography and migration modules contain simple parameters based on physical properties, enabling users to set up and iterate upon their workflow rapidly. The tomography algorithm executes in hours or even minutes versus traditional approaches which can take days. Superior Technology The tomography is a careful implementation of a true 3D algorithm that achieves performance by carefully managing resolution - it is not a 2D algorithm extended to 3D. For prestack depth migration, a 3D plane wave migration was implemented in order to provide the most accurate migration that is still fast enough to iterate in a velocity model building workflow. Harnesses Latest Multi-Core Clusters & Grid Computing DepthCharge was engineered to leverage all of the processing resources across a computer network. A robust approach to job balancing and execution, DepthCharge is designed specifically to work around typical or even catastrophic interruptions on processing nodes or storage resources. Features 3D Tomography Focused on ease of use, the tomography algorithm is robust enough to start with stacking velocities, from which it can create a smooth interval velocity field, and then invert for raypaths, reflection points, and velocities. While it allows users to constrain the solution with layers if they choose to, it does not require that for good results – in other words users don't have to spend hours picking horizons on what may be complicated and noisy data. Finally, the speed of the tomography algorithm is remarkable – users can expect this algorithm to run in hours instead of days. The output velocity file is used to drive depth imaging algorithms, including the new 3D plane wave migration.
