“…Steep‐sided shelves and isolated platforms may be more prone to creating trapping geometries due to steeper slopes promoting bypass margins and preventing an accumulation in the fan from leaking to the up‐dip carbonate system (Figure 20C). In the Permian Basin, mixed carbonate–siliciclastic deposition allows fans to be encased by siliciclastic muds, which form top, base and lateral seals (Clayton & Kerans, 2014; Dutton et al, 2005). Alternative trapping geometries for both ramps and shelves can occur if a post‐depositional structural tilt has rotated the transition (facies pinch out) to basinal facies structurally higher (Figure 20B).…”

Deepwater carbonate deposition is relatively poorly understood but an area of vigorous research in academia and industry, where these deposits are a significant component of many unconventional petroleum reservoirs. Recent studies of modern deepwater carbonates have highlighted the wide variety of depositional processes, sediment types and resultant geomorphology; however, well‐documented outcrops of ancient systems, their rock types and architecture are relatively sparse. The Mississippian Lake Valley Formation provides world‐class exposures of slope‐basinal carbonate deposits. The Tierra Blanca and Doña Ana members comprise submarine fans that are >14 to 20 km in length, >5 km wide, and exposed in strike and dip view, affording a unique opportunity to constrain the architecture, rock types and sedimentary processes. Tierra Blanca and Doña Ana sedimentation was dominated by crinoids shed from an up‐dip platform and supplemented by sediments sourced locally from Waulsortian mounds. Depositional processes include turbidity flows, debris flows and hybrid sediment‐gravity flows. The Tierra Blanca submarine fan thins towards its lateral flanks and distal fringe, where deposits become more mud‐dominated, gravelly grain‐supported flows are less common, and fewer beds have scoured bases. In proximal settings, bed tracing complemented by measured sections allow mapping of stratal surfaces and identification of stories, elements and complexes. The Tierra Blanca evolved from more unconfined to confined deposition. Point‐sourced deposition of the Tierra Blanca fan required a funnelling mechanism, likely due to bathymetry created by Waulsortian mounds or possibly a platform margin re‐entrant. Outcrop exposures illustrate that younger Doña Ana submarine fan deposits onlap onto, and compensationally stack with, the thickest portions of the antecedent Tierra Blanca fan. These outcrops illustrate both similarities and differences between carbonate and siliciclastic gravity flow deposits. Similarities include comparable deposit types, depositional processes and architecture; differences relate to hydrodynamics of carbonate grains, funnelling mechanisms for point‐sourced deposits and sequence stratigraphic forcing.

“…Productive reservoirs are primarily patch reefs that grew on positive tectonic features. Strawn production is dominated by accumulations of gas and gas liquids in the western part of the Delaware Basin and accumulations of oil and associated gas in the eastern part of the basin Dutton et al, 2005). Gases are predominantly hydrocarbons with an average methane concentration of 84 percent; gas liquids constitute approximately 14 percent of the Strawn gases.…”

Carbon dioxide (CO 2 ) occurs as a common component of natural gases throughout New Mexico. In most gases, CO 2 is a minor constituent and comprises less than 1 percent of the gas. More rarely, CO 2 is the dominant component of the gases and may constitute more than 99 percent of the gas. Some accumulations of this nearly pure CO 2 have been produced commercially for their CO 2 content.Most gases in the Permian Basin of southeastern New Mexico contain less than 1 percent CO 2 . In general, stratigraphic units comprised predominantly of carbonate rocks harbor gases that contain higher percentages of CO 2 than units comprised predominantly of siliciclastic sedimentary rocks.In the San Juan Basin of northwestern New Mexico, most gases in Cretaceous reservoirs contain less than 1 percent CO 2 . Cretaceous gases contain more than 1 percent CO 2 in the deep northern part of the basin. Gases in Pennsylvanian reservoirs contain more than 10 percent CO 2 along trends on the Four Corners platform and in the deeper parts of the San Juan Basin. Gases in Mississippian reservoirs are comprised of more than 90 percent CO 2 over large areas.Widespread accumulations of gases that are nearly pure CO 2 are present over large parts of the Bravo Dome and Sierra Grande uplift of northeastern New Mexico.CO 2 has been produced commercially from the Bravo Dome field that has yielded a cumulative production of more than 1.2 trillion ft 3 CO 2 gas. Triassic sandstones are secondary reservoirs at Bravo Dome. CO 2 has also been produced from the much smaller, now-abandoned Des Moines field on the Sierra Grande uplift. Significant potential remains for undiscovered CO 2 resources on the Sierra Grande uplift and Bravo Dome.In north-central New Mexico, CO 2 -rich gases are present within Pennsylvanian and Lower Permian sandstones in the vicinity of large igneous intrusions in the Las Vegas Basin. In the Raton Basin, gases composed primarily of CO 2 occur in Triassic sandstones and in the Glorieta Sandstone (Permian).

“…Yet higher in the section, Strawn (Middle Pennsylvanian) patch reefs were formed over the top of pre-Strawn paleostructures; reef growth was localized over the tops of pre-existing structures that had bathymetric expression (Thornton and Gaston, 1967;Harris, 1990). These Strawn patch reefs form numerous and significant oil and gas reservoirs in the New Mexico portion of the Permian Basin (see Broadhead et al, 2004;Dutton et al, 2005).…”

Mississippian strata in southeastern New Mexico, including the Barnett Shale: thicknees, structure and hydrocarbon plays

Mississippian strata of southeastern New Mexico are Kinderhookian to Chesterian in age. In Eddy, Lea, and southern Chaves Counties, depth to the top of the Mississippian ranges from 5,500 ft in the northwest to 18,500 ft in the southeast. Lower Mississippian (Kinderhookian and Osagian) strata are 0 to 800 ft thick and are comprised of marine limestones and minor shales and chert. Upper Mississippian (Meramecian and Chesterian) strata are 0 to 1600 ft thick and are comprised of marine limestones and shales. Within the Upper Mississippian section, there is a sharp transition from shelf deposits dominated by limestones in the north to the basinal Barnett Shale in the south. Forty gas and oil pools have been productive from Mississippian reservoirs in Eddy, Lea, and southern Chaves Counties. Twenty-four pools have been productive from Upper Mississippian reservoirs and 12 have been productive from Lower Mississippian reservoirs. Four gas pools have been productive from both Upper and Lower Mississippian reservoirs. Productive Upper Mississippian reservoirs are shelfal limestones in the north. The Mississippian play is one of the smallest plays in southeastern New Mexico and has yielded a cumulative 28 BCF gas and 1.3 MMBO from the 40 pools in Eddy, Lea, and southern Chaves Counties. Most production has been obtained from Chesterian limestone reservoirs of the northern shelf. Chesterian reservoirs are concentrated in the San Simon Channel where uppermost Chesterian strata were preserved prior to deposition of Early Pennsylvanian sediments. Four subplays are identified in the Mississippian of Eddy, Lea, and southern Chaves Counties of southeastern New Mexico: (1) Chester shallow marine limestones in the San Simon Channel and related structurally low areas on the northern shelf; (2) Upper Mississippian limestones interbedded with Barnett shales just south of the shelf-basin transition; (3) small and widely disseminated reservoirs in lower Mississippian limestones in the north; and (4) the as-yet untried Barnett Shale in the south.
