GEOLOGIC SUMMARY SULFUR RIVER PROSPECT, HUNT
COUNTY,TX
The
IMC #1 Wassom was drilled in 1982, and reached an initial total depth of 7870Õ
in Lower Paleozoic Joins Formation. The well was re-entered by H.L. Brown of
Midland in 1996 and deepened to 10402Õ; the formation at total depth was middle
Arbuckle Group, specifically the Kindblade Formation. Gas and water were tested from the ÒBrown ZoneÓ of the Kindblade
Formation, but were uneconomical. Nonetheless, the original test and subsequent
deepening established reservoir rock in the Arbuckle dolomite. Additionally,
several older wells contain thick, porous and permeable Simpson-Tulip Creek
sands, ranging from 170Õ to 270Õ of clean, frosted, porous and permeable sands.
Samples
from the IMC #1 Wassom were examined by North Texas Sample Service, revealing
the well had drilled from Mesozoic Cotton Valley sands directly into Lower
Paleozoic Simpson clastics and limestones. Subsequent examination of the
Arbuckle samples by Jack Latham of Kiowa Lake indicated shelfal dolomites and
limestones in the Arbuckle Kindblade Formation as well. Moreover, these
clastics and limestones are considered shelf (edge) ÒArbuckleÓ in nature.
The
anomaly presented is a Lower Paleozoic, shelfal area. Subsurface well control
indicates no thrusting at all to the south and east of the #1 Wassom. The Amoco
#1 Stewart, NW Hopkins County, establishes more than 10,000Õ of vertical separation
between the ancestral Lower Paleozoic shelf edge occupied by the #1 Wassom et
al wells and the successor Basin of East Texas. The latter shelf
edge/detachment zone is easily defined by Bouguer gravity and substantiated by
seismic and the limit of the Louann salt.
The
subsequent withdrawal and rotation of the Amazonian plate southward during
Middle Pennsylvanian left a breach between the successor East Texas Basin and
the Ouachita thrust sheet. Uplift/short range thrusting of the shelf edge
blocks were the last minor episode of the thrusting, as the impinging plate
lost impetus.
Sample
information provided by North Texas Sample Service from nearby wells indicates
differing Formations surrounding the Prospect Block. These are variously,
Stanley shales; Jackfork shales and quartzites; Big Fork cherts and limestones;
Womble shales; Novaculites, and so forth. As the samples and Bouguer gravity
show, these various Ouachita Formations occur horizontally in clusters,
separated from one another by interior thrust and wrench faults. As is the case
with Wilburton Field in Latimer County, OK, the Block is from 4000Õ to 10,000Õ
structurally higher in all four directions to the blocks surrounding it.
Sample
and subsurface well data indicate at least 1000Õ of structural advantage may be
gained to the IMC #1 Wassom, both in the 200Õ Tulip Creek sands as well as the
Arbuckle Kindblade Formation. The areal extent of the Prospect is in excess of
10,000 acres, permitting reserves on the order of .5 to 1 TCF to be emplaced.
The Arbuckle Kindblade Formation can be tested at a depth of 10,000Õ. The area
is quiet, and unleased.
Subsequent
to all my work and mapping, Reeves Exploration of Burleson, TX, processed
voluminous data from his analyses of hydrocarbon seeps in the area. The
interpretation supplied herein corroborates to a high degree the geologic
interpretation, and indicates the entire 20,000 acres within the thrust block
to have hydrocarbons beneath.
In
summary, the Prospect is regionally anomalous by multiple thousands of feet,
being upthrown in all four directions. The reservoirs are exceptional, and
there are shows downdip. Though the geology is complex and somewhat
indecipherable, the risk to return is equally exceptional. Basically, this is a
company maker as of old.
