The Wink area is above the crest of the deepl y buried Capitan Reef and is just 2 mi east of a major dissolution trough that contains anomalously thick Late Permian, Triassic and Cenozoic sediments. Salado-age dissolution had not been recognized previously because of the obvious dissolution, collapse and infilling of the nearby dissolution trough during post-Salado time. The Salado Formation is informally divided into eight units, based upon examination of geophysical logs of 47 wells drilled in the four -section study area in Winkler County, Texas. Anomalous local thinning of Salado salt units, accompanied by anomalous thickening of overlying Salado rock units at the same site, is the major evidence of this Salado-age dissolution; anomalously thick local accumulations result from sedimentary filling of depressions created by dissolution and subsidence of underlying salts. Each of the Salado units thins anomalously by 15 -50 ft at one or several sites in the area, whereas five of the younger units thicken anomalously by 10 -45 ft above the sites of thinning. These thickness anomalies typically occur within horizontal distances of 1000 ft or less.","PeriodicalId":203655,"journal":{"name":"Carlsbad Region (New Mexico and West Texas)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129006520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extensive irrigation began in the 1950s and the area has been a prolific producer of cotton, alfalfa, melons, onions and garlic. Ground water for irrigation is pumped from underlying Permian carbonates (Bone Spring and Victorio Peak formations). Comparison of data from May 1992 with those of the late 1940s and 1960 shows an average 30-foot drop in the potentiometric surface, but hydraulic gradients in the aquifer are very small. The water table is nearly horizontal and pumping discharge is high, which indicates very high transmissivities, and there is a subtle east-west trough just south of Dell City. There are indications of local recharge within the irrigation area. The distributions of total dissolved solids (TDS) show an unexpected rise in the center of the irrigation district. TDS concentrations decrease radially, until they rise sharply again near the salt flats. This indicates that there has been little salt-water intrusion. The higher TDS near Dell City may be caused by irrigation return flow and a greater proportion of evaporite minerals in shallow sediments within a paleotopographic low. We suggest that the flow system is strongly fault-controlled. This has minimized salt-water intrusion by juxtaposition of hydrostratigraphic units and may control effective recharge areas.","PeriodicalId":203655,"journal":{"name":"Carlsbad Region (New Mexico and West Texas)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123051078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ewing","doi":"10.56577/ffc-44.155","DOIUrl":"https://doi.org/10.56577/ffc-44.155","url":null,"abstract":"—The West Texas Basin is a complex late Paleozoic basin on the unstable craton. It is a composite of Early Pennsylvanian and Early Permian deformation and Early Pennsylvanian through late Permian subsidence. The postdeformational bowl of subsidence of the West Texas Basin is broadly similar to the subsidence of true intracratonic basins, such as the Michigan and Williston Basins. Unlike these basins, however, the present boundaries of the West Texas Basin do not follow or preserve the original limits of subsidence. The southern, western and to a lesser degree the eastern margins have been altered by pre-Albian uplift and erosion, assisted by Laramide and Tertiary uplift on the western margin. Only the northern margin is preserved, although it is complicated by the neighboring Anadarko Basin. The Pennsylvanian and Permian subsidence continued to the south and west of the preserved basin and probably connected with the Orogrande and Pedregosa Basins. This larger \"Permian Basin\" contains both the Central Basin axis and the Diablo-Pedernal axis as intrabasin tectonic belts. The post-Permian erosion was probably due to a combination of uplift on the flanks of the Triassic-Jurassic rift complex, which resulted in the opening of the Gulf of Mexico, and uplift on the flanks of the Early Cretaceous Bisbee–Chihuahua Trough. Reconnaissance subsidence analysis of the West Texas Basin discloses a complex pattern of subsidence rates through the Permian. The most rapid tectonic subsidence took place in the Wolfcampian of the southern Delaware Basin, between the Marathon thrust sheets and the Fort Stockton uplift. Flexural subsidence is probably responsible. Post-Wolfcampian (postdeformational) subsidence of unknown origin continued to be centered in the north-south Delaware Basin trough, but extended north and east over a broad area of the Central Basin axis, the Midland Basin and the Northwest shelf to form the \"Permian Basin.\"","PeriodicalId":203655,"journal":{"name":"Carlsbad Region (New Mexico and West Texas)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126154578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The New Mexico part of the basin has produced a cumulative total of 4142 million barrels of oil (MMBO) and 18.7 trillion ft 3 (TCF) of natural gas. It contains 1112 designated, discovered oil reservoirs and 672 designated, discovered gas reservoirs. Of these reservoirs, 1781 have been grouped into 17 plays based on common geologic characteristics. The Permian section has dominated production with 10 plays that have produced 2834 MMBO and 11.2 TCF gas. Production of both oil and gas are dominated by Leonardian- and Guadalupian-age dolostones and sandstones of the Abo, Yeso, Glorieta, San Andres, Grayburg, Queen and Yates formations. Most of the reservoirs in these formations were deposited in a back-reef, restricted-shelf setting. The most prolific Abo reservoirs were deposited in a shelf-margin reef setting. Significant production is also obtained from basinal carbonates of the Bone Spring Formation and basinal sandstones of the Delaware Mountain Group. The pre-Permian section has also yielded major volumes of oil and gas. Reservoirs in the 7 pre-Permian plays have produced 973 MMBO and 6.9 TCF gas. Pre-Permian oil production is dominated by restricted-shelf dolostones of the Ellenburger, Simpson and Montoya formations (Ordovician), restricted-shelf dolostones of the Thirtyone and Fusselman formations (Silurian-Devonian) and open shelf–shelf margin limestones and dolostones of the Canyon and Cisco sections (Pennsylvanian: Missourian-Virgilian).

Sonnenfeld","doi":"10.56577/ffc-44.195","DOIUrl":"https://doi.org/10.56577/ffc-44.195","url":null,"abstract":"—San Andres Formation outcrops in Last Chance Canyon are interpreted to contain two large-scale depositional sequences, upper San Andres sequence 3 and upper San Andres sequence 4. Facies associations, volumetric proportions of carbonate and siliciclastic strata and depositional topography change progressively through the course of the upper San Andres sequence 4. These aspects change in a predictable fashion and correspond to position within the lowstand, transgressive and highstand systems tracts. Units within the lowstand to transgressive systems tracts record a progressive decrease in sedimentation rate, depositional energy and siliciclastic content. This reflects a long-term transition from detrital, siliciclastic-dominated, point-sourced slope sedimentation to increasingly autochthonous, carbonate-dominated, line-sourced slope sedimentation. Within carbonate strata of the transgressive systems tract, long-term relative sea level rise is interpreted from thick outer-shelf deposits, highly aggradational to mounded fusulinid shoals and net stratigraphic rise of the fusulinid facies tract. The most carbonate-rich and bioherm-bearing interval of the entire sequence overlies a distinctive maximum flooding surface capping the transgressive systems tract. Ensuing high-frequency sequences of the middle to late highstand systems tract show pronounced progradational offlap and record a progressive increase in the volume of siliciclasts accumulated on the outer shelf. A karsted toplap surface represents a subaerial unconformity and sequence boundary capping upper San Andres sequence 4. Embedded within upper San Andres sequence 4 are numerous high-frequency sequences that show the following similarities to larger, seismic-scale depositional sequences: (I) stratal geometries; (2) the nature of bounding surfaces; (3) the timing of bioherm development; (4) siliciclastic to carbonate facies evolution; and possibly (5) point-source to line-source evolution. One of the most important aspects of stratigraphic self-similarity, best documented within the highstand systems tract of upper San Andres 4, involves the seaward transition from asymmetric shallowingupward hemicycles at the toe-of-slope and seaward. Each symmetric cycle includes an inferred deepening-upward phase or \"transgressive hemicycle,\" characterized by a waning siliciclastic influence, succeeded by a shallowing-upward phase, or \"regressive hemicycle,\" characterized by flourishing, prograding carbonates. The concept of qualified stratigraphic self-similarity does not diminish the importance of facies variation or \"dif-ferentiation\" within and among sequences; it merely emphasizes that the physical stratigraphy of a sequence reflects spatial and temporal variations in accommodation/sediment supply ratios but is relatively independent of absolute duration.","PeriodicalId":203655,"journal":{"name":"Carlsbad Region (New Mexico and West Texas)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125407012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structures derived from two major periods of tectonic activity control the location of sulfur mineralization. Pre-mineralization faults developed in response to Laramide compressional tectonics in the Late Cretaceous to early Tertiary, as indicated by breccia clast assemblages filling paleokarst features along the faults. Basin and Range extensional tectonics uplifted the western Delaware basin beginning in the middle to latest Miocene, resulting in a change in basin hydrodynamics conducive to bioepigenesis. Age of mineralization may be less than 5 Ma, based on mineralization crosscutting karst-related deposits thought to be of Ogallala (middle-late Miocene) age. Crude oil analyses and con - elation of anionic ground water constituents indicate the Guadalupian Cherry Canyon Formation is a probable source for hydrocarbons and oxygenated waters necessary for bioepigenetic sulfur deposition at Culberson. Sulfur occurs as microcrystalline disseminations in replacement limestone and as crystalline vug fillings associated with epigenetic barite, celestite and isotopically light carbonate minerals. The timing and kinematics of the Culberson and Phillips Ranch and Nestlerode, 1992) fault systems may be related to similar regional tectonic events, but locally different stress regimes, during the Late Cretaceous. The trend of these faults conforms to wrench fault tectonic features described by Bolden (1984) as part of a northwest- trending series of left-lateral faults that lie north of and subparallel to the Texas lineament. The locations of the Culberson and Phillips Ranch deposits are within a 6-mi-wide northwest-trending disturbed zone that Bolden named the Pecos lineament. According to Bolden (1984) and others, repeated movement along these faults occurred between the Mississippian and Tertiary. The fault trends identified at Culberson are parallel to a right-lateral conjugate shear stress regime within the disturbed zone. The fault trends at Phillips Ranch are compatible with a related tensional regime. A regional wrench fault mechanism is a possible explanation for the differences in the fault kinematics apparent at Phillips Ranch and Culberson, with the timing of fault development in general agreement with relative timing of breccia development along faults at Culberson. However, as noted above, horizontally slickensided surfaces may not be reliable indications of tectonic activity. The high- angle dips and local reversals of offset along the strike of the faults at Culberson suggest reverse faulting that was caused by a compressional regime. We recognize the possible existence of numerous normal faults that, based on limited borehole information, might suggest offset re- versal along a single fault. However, we believe that the faults originally formed in a compressional ","PeriodicalId":203655,"journal":{"name":"Carlsbad Region (New Mexico and West Texas)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125501371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
