Depth domain. The interpreted 2D seismic information also offered the geometry input for the petroleum method model (Section 5).Figure two. Overview map of Farnsworth Field study site inside Ochiltree County, seismic lines and nicely information utilized in this study, and areas of 2D seismic lines and 3D seismic survey. The inset shows the place (grey) on the map. The Killingsworth well has been used for the well-tie with DC-NEP-10.

Interpretation of seismic lines DC-NEP-10 (short east est line) and DC-NEP-33 (north and south), and well-tie with all the Killingsworth nicely (light blue). Locations of lines and Killingsworth well shown in Figure 2. The Atokan/Morrowan Lapatinib ditosylate Epigenetics formations are mostly transparent, and their boundaries cannot be resolved in these data. The Missourian Kansas City Group and Late Devonian-Early Mississippian Woodford shale are interpreted within the 3D seismic data (Figure 5). No seismically resolvable faults are observed around the 2D seismic lines inside the Atokan or Morrowan formations.Formations usually dip southeastward in our study region, which can be in agreement with regional trends [22,61,62]. The dip increases with stratigraphic age and units have a tendency to thicken toward the deep basin. The Atokan and Morrowan formations are continuous, somewhat transparent seismically, and cannot be resolved individually on these low-resolution lines. The major Mississippian is interpreted as an angular erosional unconformity, formed because of the Wichita orogeny [24]. You’ll find no indications for faulting or seismic chimneys in both the east est and north outh lines in the Atokan and Morrowan formations. 3.2. Interpretation of 3D Seismic Survey 3D Reflection seismic data (Figures two, 5 and six) have been acquired in 2013 by SWP by means of WesternGeco more than an approximately 42 mi2 surface area, with complete fold covering 27 mi2 . The geophones had 33 ft. Cyclosporin A Cancer spacing and dense vibroseis supply points using a sweep frequency of 200 Hz. Processing steps and survey characteristics are described by [63]. Preliminary interpretations of this dataset recommended that the Morrow B reservoir may very well be faulted, with faults striking E, S, and SE [64]. Our interpretations show that the seismic discontinuities that were interpreted as faults in White et al. [64] are erosional characteristics, incised channels, and karst structures. Wells 13-10A and 32-8 (areas shown in Figure five) have been utilized for nicely ties. The Morrow B reservoir rock reaches a maximum thickness of 70 ft in Farnsworth Field, and its boundaries can’t be resolved within the seismic information. Since the exact location of your Morrow B horizon in the seismic data is therefore uncertain, a reflector within the proximity on the Morrow B (Figure 5a) was traced confidently within the seismic information. In further analyses, we made use of an isopach map with the Morrow B that we produced from interpolation of 346 nicely logs. Figure five shows the position from the Morrow B reservoir layer with respect towards the overlaying Thirteen Finger Limestone and Kansas City Group, along with the underlying Woodford and Hunton Formations. In Farnsworth Field, paleozoic formations dip slightly toward the southeast (Figur.
