Abstract
This paper describes the elements of a multi-disciplinary data integration and reservoir characterization of an unconventional limestone and shale reservoir in the US midcontinent region (north-central Oklahoma). The reservoir is the Mississippi Limestone which overlays an organic calcareous mudstone (the Woodford Shale) that in some areas is also considered a reservoir unit. The base data set is a 180 sq mi high density, full azimuth, multi-component survey that was designed, acquired and processed using a VectorSeis Nodal acquisition system. Processing was carefully performed in order to quantify compressional and converted wave anisotropy. The last step was a reservoir characterization that integrated rock and fracture properties with a full suite of calibration data from multiple wells, including vertical and lateral FMI logs, mudlogs, Sonic Scanners, chemical tracer in the laterals, completion results and microseismic data. This abstract describes our results from a portion of this data set, specifically surrounding a vertical saltwater disposal well (George 1–23 SWD) and two laterals (23–1H and 23–2H). We describe the data elements, how they integrate together, and the implications for reservoir conditions. More detailed descriptions of the input data and the analytical results will be presented in subsequent papers.
