What types of constraints enhance the effectiveness of geophysical inversion modelling?
While the earth can be infinitely complex, when we conduct exploration we generally have pretty good models of what we are looking for and the environments in which we are working. For example, in petroleum exploration we seek petroleum traps in sedimentary geology, and in hard-rock mineral exploration we understand the basic geologic plays – things such as strike and dip of rocks, and the style of complexity for the target deposits, and so on. We also have other information to help guide us – seismic interpretations in petroleum, or surface mapping, depth of overburden and possibly drilling information in mineral exploration plays. All this information allows us to build constraints that help improve the accuracy of 3D inversions. However, the workflow to define and introduce constraints continues to be a challenge. With Geosoft voxel inversion technologies, we have taken a big step in making this as simple as possible, and in on-going development over the coming months and years we w
