Evidence for sediment fan deposition on outer Texas Shelf during Miocene Eustatic Sea level highstands
Four types of data were reviewed in an attempt to clearly define the environments of deposition for reservoir sands in the Matagorda 668 field; well log curve shapes, seismic amplitude responses, micropaleontology, and thin section sedimentary petrology. All four lines of evidence support the interpretation that these lower Miocene sands were deposited as fan complexes. The sands exhibit three distinctive curve forms: coarsening upward, fining upward, and cylindrical-serrate. These represent respectively fringe settings around the perimeter of the fan where deposition from turbid flow dominates, proximal fan settings where settling from suspension is the more dominant process, and a collection of environments in medial settings intermediate between the two end members just described.
