Abstract
Flow-Unit Scale Dynamic Stratigraphy in Canyon Sandstone 
Sequences
, Sonora Field, Sutton County, Texas
Abstract
The Sonora and Sawyer Canyon Fields provide a sound case study for deep-water sandstones deposited in multiple-point-sourced, low sand to shale-ratio systems. A series of parasequence sets developed, each 80 to 150 feet thick, comprised of finegrained sandstone bodies encased in shale. The sedimentary compaction history appears to create a compensatory distribution of the sandy depositional elements in succeeding parasequence sets.
The parasequences
appear to back step from an early, lower-slope intra-slope sub-basin seven miles southwest of the city of Sonora. The sandstone depo-center reaches a high-stand location northeast of Sonora where the sandstones comprise large, integrated and coalesced fans that have some of the highest porosity and highest cumulative production in the field.
As the high stand fan complex reached its maximum extent, continued subsidence and sediment input created two succeeding elongate progrational pulses that prograded back out across the earlier complexes of parasequence sets.
