“…In the northern part of the project area, the lower Morrow shale has not been correlated or mapped because it is Mississippian level (see Casavant, 1999), the computer-generated contour map depicts the fault zone as closely spaced contours. The Central Basin Platform, formed by highangle faults (Hills, 1984;Haigler and Cunningham, 1972) is also clearly defined by the structure contour map on top of the Mississippian System. Again, the closely spaced contours define the fault zones that bound this uplifted tectonic block.…”

“…During the Late Mississippian, the area was subdivided into a northern shelf dominated by deposition of limestones and a southern basin dominated by deposition of the Barnett Shale (Figure 3; Hamilton and Asquith, 2000;Broadhead, 2006aBroadhead, , 2006b.

Basinal dark-gray to black marine shales in the New Mexico part of the Permian Basin that have been traditionally correlated as the Barnett Shale (Upper Mississippian) are late Mississippian to Morrowan (Early Pennsylvanian) in age. The Upper Mississippian Barnett Shale in the south correlates northward with Chesterian and Meramecian strata on the Mississippian shelf. The shelf strata in the north are dominated by marine limestones; tongues of Barnett shales extend northward onto the shelf where they intertongue with the shelf limestones. The overlying Morrowan (Lower Pennsylvanian) shales grade northward into a sandy facies consisting of interbedded dark-gray to black shales and lenticular sandstones. That part of the Upper Mississippian -Lower Pennsylvanian shale sequence that is correlated as the Barnett Shale consists of 200 to 350 ft of dark-gray to black shale with minor thin sandstones and minor thin limestones throughout most of its extent in the New Mexico part of the Permian Basin. The overlying Morrowan (Lower Pennsylvanian) shales are subdivided into two stratal units, the lower Morrow shale and the upper Morrow shale. The lower Morrow shale consists of 200 to 350 ft of dark-gray to black marine shales and minor thin sandstones. The upper morrow shale consists of 100 to 800 ft dark-gray to black marine shales and minor thin sandstones.The Barnett Shale contains mature, organic-rich petroleum source rocks. Total Organic Carbon (TOC) content ranges from 0.85 to 4.9 percent in the New Mexico part of the Permian Basin. The kerogen population is dominantly gas prone but also appears to contain oil-prone types. The Barnett Shale is thermally mature throughout its extent in the New Mexico part of the Permian Basin. A northwest-southeast trending fairway for Barnett shale gas exploration extends throughout the western portion of the New Mexico part of the Permian Basin. This fairway is defined by the most thermally mature source rocks with TOC contents greater than 2 percent.Exploratory drilling for shale gas has not yet taken place in the New Mexico part of the Permian Basin.The lower and upper Morrow shales contain sufficient TOC to be considered source rocks in southeastern New Mexico and are thermally mature. The Morrow shales are less thermally mature than the deeper, underlying Barnett Shale.

“…Since 1943, cumulative helium production from New Mexico reservoirs is estimated to be approximately one billion ft 3 (BCF), (Broadhead and Gillard, 2004). This is dwarfed by annual U.S. production of 2.9 BCF in 2011 and annual U.S. sales of 4 BCF in 2011 (Madrid, 2012) Hills (1984) and Dutton et al (2005). Red lines indicate boundaries between major paleobathymetric elements.…”

“…In the early Paleozoic period, it was a carbonate shelf deposit in a shallow sea, gently inclining southeast and having multistage tectonic evolutions. This basin mainly consists of the Central Basin platform, the Delaware Basin, the Midland Basin, and the Val Verde Basin (McKee et al 1967;Hills 1984;Yang and Dorobek 1995). The Michigan Basin is located in the east of the North American platform.…”

“…The Permian Basin has been subject to Paleozoic marine and Mesozoic-Cenozoic Compiled with data from IHS Energy , 2013), C&C Reservoirs (2005), and USGS (2007 continental sedimentary systems since the end of the Cambrian period. In the Lower Paleozoic stratigraphic sections, several unconformities exit, and most of them between shallow shelf carbonate deposits (Hills 1984;Adams and Keller 1996). The Michigan Basin was deposited on a set of transgressive sandstones and sandy dolomites in the Cambrian period, which is in unconformable contact with Ordovician marine carbonate rocks, shales, and sandstones.…”

Formation and distribution characteristics of Proterozoic–Lower Paleozoic marine giant oil and gas fields worldwide

There are rich oil and gas resources in marine carbonate strata worldwide. Although most of the oil and gas reserves discovered so far are mainly distributed in Mesozoic, Cenozoic, and upper Paleozoic strata, oil and gas exploration in the Proterozoic-Lower Paleozoic (PLP) strata-the oldest marine strata-has been very limited. To more clearly understand the oil and gas formation conditions and distributions in the PLP marine carbonate strata, we analyzed and characterized the petroleum geological conditions, oil and gas reservoir types, and their distributions in thirteen giant oil and gas fields worldwide. This study reveals the main factors controlling their formation and distribution. Our analyses show that the source rocks for these giant oil and gas fields are mainly shale with a great abundance of type I-II organic matter and a high thermal evolution extent. The reservoirs are mainly gas reservoirs, and the reservoir rocks are dominated by dolomite. The reservoir types are mainly karst and reef-shoal bodies with well-developed dissolved pores and cavities, intercrystalline pores, and fractures. These reservoirs are highly heterogeneous. The burial depth of the reservoirs is highly variable and somewhat negatively correlated to the porosity. The cap rocks are mainly thick evaporites and shales, with the thickness of the cap rocks positively correlated to the oil and gas reserves. The development of high-quality evaporite cap rock is highly favorable for oil and gas preservation. We identified four hydrocarbon generation models, and that the major source rocks have undergone a long period of burial and thermal evolution and are characterized by early and long periods of hydrocarbon generation. These giant oil and gas fields have diverse types of reservoirs and are mainly distributed in paleo-uplifts, slope zones, and platform margin reef-shoal bodies. The main factors that control their formation and distribution were identified, enabling the prediction of new favorable areas for oil and gas exploration.
