Factores que inciden en la calidad de vida del jubilado
Authors: Ramírez Gálvez José Roberto 
Published: October 2019

La jubilación supone una importante reestructuración de las funciones que definen el espacio de la vida de una persona y, por consiguiente, requiere flexibilidad y capacidad de adaptación a las nuevas condiciones. “La jubilación puede ser vista como una transición que implica la ampliación, la redefinición y el cambio de papeles, la extensión del tiempo de la jubilación, es un evento que permitirá un proceso temporal y que requiere tomar decisiones, implementar y llevar las consecuencias”. La centralidad del trabajo en relación a otros elementos, como la familia, en la definición de la conciencia de sí mismo es muy diferente de una persona a otra, lo que implica que la transición a la jubilación puede requerir diferentes niveles de la reestructuración de sí mismo.
La etapa de preparación previa a la jubilación coincide con una progresiva clarificación de las actitudes sobre la jubilación y una planificación del tiempo y de la forma de su retiro de la vida laboral. En el momento de la jubilación, los planes son más detallados, pero la actitud tiende a degenerar en ansiedad y desesperación por la pérdida de su actividad laboral. Por supuesto, la fase de preparación para la jubilación tiene un significado personal diferente en función de la historia individual y de la centralidad de la actividad laboral desempeñada. La jubilación supone la pérdida de contactos sociales, pero todavía no está claro el grado de pérdida, tanto en términos de extensión de la red social, como de calidad, de apoyo recibido. Se debe de considerar el apoyo social para distinguir las diferentes fuentes (familia, amigos, etc.) y los diferentes tipos (emocional, instrumental, etc.) de apoyo social que inciden en la calidad de vida del jubilado considerando el aspecto de la actividad física, la salud, la educación, la alimentación, la actividad intelectual, la actividad sicosocial entre otros factores o aspectos importantes en el jubilado.

The early history of Dutch (local) administrative sciences: Joris in ’t Veld and the new forms of decentralization
This essay is about the Dutch PhD-thesis New forms of decentralization by Joris in ’t Veld from 1929. He was not only a competent and efficient social-democratic administrator, but he was also an early administrative scientist. Like the other early (local) administrative scientists, he mainly worked from the legal discipline. During this period however, we also see an increasing input from other disciplines, such as urban planning, economic geography, business administration and statistics. The subject of his dissertation does not come out of the blue. Like many, In ’t Veld felt strongly attracted to the problems of urban and regional development, but the various problems were not yet ripe for a final solution. An important part of his book is therefore devoted to the various solutions that have been found abroad for similar problems. In his thesis, In ’t Veld discusses various forms of governance. First of all, he looks at the way in which the arrangement of cooperation between municipalities can be improved. Where this (voluntary and forced) cooperation falls short of its nature, the institutes of the port authority and of the regional plan come into the picture. In both cases it concerns decentralization through target corporations. A solution is also conceivable through further territorial decentralization: the insertion of a new regional corporation between the province and the municipality in the form of the region (the urban region or the rural region). The urban region needs a necessary supplement in the form of a system of tax equalization to adequately do justice to the interests of the whole and of the parts. An alternative to the urban region is the unity municipality with local decentralization. His integral vision on the organization of domestic government in 1929 is also instructive for the present time.
TRANSGRESSIVE-REGRESSIVE CARBONATE FACIES OF THE SMACKOVER FORMATION, ESCAMBIA COUNTY, ALABAMA
Authors: Bradford Cynthia A. 
Published: October 2019

ABSTRACT
The Smackover Formation in Escambia County, Alabama is divided into ten facies. The transgressive facies of the basal Smackover were deposited in a lower supratidal to upper subtidal environment and consist of interbedded algal-laminated mudstone and oncolite-pellet packstone. A coated fossil packstone facies was also deposited in the lower unit of the Smackover, but in more open-marine conditions. During the deposition of the middle Smackover this facies acted as a partial barrier and restricted the energy and salinity in the landward area. These restrictions resulted in the deposition of a fossiliferous mudstone facies, which alternated with a distinctive, black laminated mudstone devoid of preserved fauna or bioturbation. The regressive upper Smackover sequence is dominated by a lagoonal pellet wackestone/mudstone. This lagoonal mudstone was deposited behind an oolite shoal which developed seaward on the slight topographic relief formed by salt movement during middle Smackover time. Landward of the lagoon, a sabkha developed which eventually prograded over the entire facies tract.
Dolomitization of the oolite grainstone and underlying lagoonal mudstone created porosity in the upper Smackover. This porosity, along with the presence of favorable structure and dense anhydrite seal provided by the overlying Buckner Formation, combined to produce an effective trap for hydrocarbon accumulation.
PALEOENVIRONMENT OF AN UPPER COTTON VALLEY (KNOWLES LIMESTONE) PATCH REEF, MILAM COUNTY, TEXAS
Authors: Cregg Allen K. , Ahr Wayne M. 
Published: October 2019

ABSTRACT
The Knowles Limestone is the uppermost unit of the Cotton Valley Group, and in Milam County, Texas it is approximately 350 feet thick and consists of shales, terrigenous dolomitic limestones, grainy limestones, and algal boundstones with stromatoporoids and corals. The boundstones represent an elongate, wave-resistant, encrusted skeletal patch reef which probably developed on a subtle, salt-generated topographic high. The narrowest width of the reef is slightly more than one mile based on facies correlations of three cored wells in the study area.
The principal reef framebuilders included massive and columnar stromatoporoids, solitary and dendroid corals, and encrusting Tubiphytes and Lithocodium algae. Dendroid stromatoporoids, digitate corals, Tubiphytes oncoids, echinoids, and various mollusks were the principal contributors to the detrital infill of the reef.
Increased dip and dip reversal of draping beds suggest that the Knowles reef achieved relief above the sea floor. Dipmeter logs indicate that the beds dip 5° northwest on the updip reef flank and 10° southeast on the downdip reef flank.
Reef-core boundstones and reef talus were consistently present downdip, and lagoonal to tidal-flat facies were common updip throughout Knowles deposition. The reef organisms eventually became overwhelmed with terrigenous sediment transported downdip as the tidal-flat environment prograded over lagoon, reef-talus and reef-core facies at the end of Knowles deposition.
Early dolomitization of tidal-flat and lagoonal facies created local porous zones in some of these rocks. However, the reef, perse, is cemented by sparry calcite and is not a potential reservoir facies.
Upper Jurassic Ammonites from the Subsurface of Texas, Louisiana, and Mississippi
Authors: Imlay Ralph W. , Herman George 
Published: October 2019

Abstract
Ammonites ranging in age from late middle Oxfordian to latest Tithonian have been found in cores obtained from nine wells in Louisiana, one well in Mississippi, six wells in eastern Texas, and one well in southern Texas. The ammonites found in the middle and upper parts of the Smackover Formation are of late middle to late Oxfordian age based on the presence of Ochetoceras, Proscaphites, Dichotomosphinctes, Discosphinctes, Ortho-sphinctes, Idoceras, and Euaspidoceras. The lower part is probably also entirely of that age based on the presence of Discosphinctes at the top of the lower fifth of the Smackover Formation in the Carter-Hope Fee No. 1 well. No ammonites have been found in the red beds typical of the Buckner Formation, but the overlying Gilmer Limestone has furnished a few specimens of Idoceras of late Oxfordian, or early Kimmeridgian age. The basal beds of the younger Bossier Formation have yielded the early Kimmeridgian ammonites Nebrodites and Ataxioceras in association with Idoceras. Above these strata are beds characterized by the Kimmeridgian genus Procraspedites and also by Glochiceras and Taramelliceras, which range as high as the basal Tithonian. The upper and middle parts of the Bossier Formation are characterized by a few ammonite genera of Tithonian age including Virgatosphinctes, Salinites, Durangites?, and Substeueroceras.
CARBONATE FACIES OF THE UPPER SMACKOVER FORMATION (JURASSIC), PAUP SPUR-MANDEVILLE FIELDS, MILLER COUNTY, ARKANSAS
Authors: McGraw Maryann M. 
Published: October 2019

Abstract
The Paup Spur-Mandevilie Fields are located in Miller County, Arkansas, about six miles northeast of Texarkana. Of more than 20 wells drilled in this field to date, twelve have produced oil from the Smackover Formation and one has produced gas condensate.
Based on an analysis of cores from nine wells and porosity plugs from a tenth well from these fields the following carbonate facies have been defined: Laminated pelsparite with shaly partings. The sedimentary features of this unit are indicative of a shallow, subtidal environment, and the sedimentary structures in the lowest part of the section show a predominance of gravity-related features. Up-section, wave-generated currents were more prevalent, which indicates that deposition occurred in shallower water.Cross-bedded and burrowed pelsparite-pelmicrite. This unit is heavily burrowed near the center of the field and interfingers laterally with intertidal cross-beds and horizontal laminations. The burrowed zone is probably indicative of slightly deeper water.Laminated to burrowed silty pelsparite with shaly partings. This unit is characterized by cycles which exhibit a decrease in wave energy. Each cycle is cross-bedded or finely laminated and rippled at the base, and shows increasing bioturbation and decreasing silt and shale content upwards.Algal biolithite and intrasparite. The most outstanding features of this unit are the bluegreen algal structures. Stromatolitic structures (largest structure in the cores is 10 cm in height) are best developed in wells to the south; however, oncolites and algal-laminated sediments occur across the field.Cross-bedded oosparite. Sedimentary accumulations in this unit are a high-energy, oolitic sand belt. Bimodal cross-beds and horizontal laminations characterize this unit.
The Smackover sediments of the PS-M Fields were formed near the mouth of a shallow embayment on the ancestral Gulf of Mexico shelf. A depositional model for the area shows ooid shoals forming over pre-Smackover structural highs where maximum wave energy was expended over their southeast flank. Peripheral facies formed in protected areas and where wind-driven tidal variations had greater influence. Bluegreen algal structures modified environemnts to the west.
Early diagenetic features of the Upper Smackover indicate an active, freshwater phreatic environment. During early diagenesis partial to complete dissolution of allochems occurred, which created most of the field’s porosity. Primary cements are finely crystalline calcite occurring as equant to bladed crusts and equant, interlocking mosaics which coarsen toward the pore centers.
Later diagenetic features include solution enhancement of pore space during hydrocarbon migration. Anhydrite and celestite are rare, but ubiquitous - the anhydrite ocecurring as pore filling and replacement and the celestite occurring as pore and fracture fill. Locally, baroque dolomite occupies allochem molds.
SIGNIFICANT FOSSILS OF THE KNOWLES LIMESTONE, LOWER CRETACEOUS, TEXAS
Authors: Scott R.W. 
Published: October 2019

ABSTRACT
Cores of the Knowles Limestone in Robertson and Milam Counties, Texas, East Texas Embayment, have yielded 25 taxa of algae, tintinnids, foraminifers, sponges, corals, stromatoporoids, and Incertae Sedis. Many of these Tethyan taxa are reported for the first time from the Gulf Coast region. The tintinnids demonstrate correlation with upper Berriasian to Valanginian assemblages of the Mediterranean area. The other fossils are longer ranging Upper Jurassic and/or Lower Cretaceous taxa. This Knowles assemblage represents a shelf-to-basin suite of paleocommunities, including coral-algal reefs.
Jurassic Unconformities, Chronostratigraphy and Sea-Level Changes from Seismic Stratigraphy and Biostratigraphy
Authors: Vail P.R. , Hardenbol J. , Todd R.G. 
Published: October 2019

Abstract
Seventeen global unconformities and their correlative conformities (sequence boundaries) subdivide the strata of the Jurassic and earliest Cretaceous into genetic sequences produced by 16 eustatic cycles. These 16 cycles make up the Jurassic supercycle. Eight of the global unformities are both subaerial and submarine (Type 1), and are believed to have been caused by rapid eustatic falls of sea level. Nine of the unconformities are subaerial only (Type 2), and are believed to be related to slow eustatic falls of sea level. In addition, 16 marine condensed sections (starved intervals) have been identified. These condensed sections are interpreted to be related to rapid eustatic rises of sea level. Unconformity recognition is locally or regionally enhanced by periodic truncation of folded and faulted strata during sea-level lowstands and onlap onto topographic highs during sea-level highstands, but we find no evidence that the tectonics caused the global unconformities. The 16 eustatic cycles that make up the Jurassic supercycle correspond to 16 global chronostratigraphic intervals that subdivide Jurassic strata into a series of genetic sequences, which are recognizable from seismic, well and outcrop data.
The Jurassic unconformities and the stratal and facies patterns between them are caused by the interaction of basement subsidence, eustatic changes of sea level, and differing sediment supply. Detailed analyses of the sediments with seismic stratigraphy and well data permit quantification of the subsidence history and reconstruction of paleoenvironment and sea-level changes through time. The intergrated use of seismic stratigraphy and biostratigraphy provides a better geologic age history than could be obtained by either method alone. Paleobathymetry, sediment facies, and relative changes of sea level can be interpreted from seismic data and confirmed or improved on by well control. Geohistory analysis based on geologic time-depth diagrams provides a quantitative analysis of total basin subsidence. When this subsidence is corrected for compaction and sediment loading, the tectonic subsidence and long-term eustatic changes may be determined. Short-term, rapid changes of sea level can be demonstrated from seismic, well and outcrop data. The stratigraphic resolution of these changes rarely allows exact quantification of their magnitude, but a minimum rate of change of sea level often can be determined.
HIGH RESOLUTION THREE-DIMENSIONAL SEISMIC SURVEY OVER THE GEOPRESSURED-GEOTHERMAL RESERVOIR AT PARCPERDUE, LOUISIANA
Authors: KINSLAND GARY L. 
Published: October 2019

ABSTRACT
A three dimensional, 3-D, high resolution seismic survey has been performed over the geopressured-geothermal reservoir of the Dow/DOE depletion experiment at Parcperdue, Louisiana. This survey was performed using the 1024 channel, sign-bit system of Geophysical Systems Corporation (GSC). At the present time, processing by GSC and by the University of Houston Allied Geophysical Laboratories (UHAGL) has yielded unmigrated 2-D reconstruction lines from the data volume. A preliminary interpretation of these data indicates that the reservoir is fault bounded as interpreted and presented by Dow Chemical Corporation in the proposal for the depletion experiment.
A 3-D physical model study has been performed by UHAGL. This study illustrated that the field 3-D survey should be able to resolve the geometry of the geopressured-geothermal reservoir and illustrated the capabilities of the UHAGL facilities to handle 3-D data.
Future processing of the data will attempt to resolve the remaining problems of 3-D time statics and offset dependent stacking velocities and will conclude with a 3-D migrated volume.
Originally, this seismic survey had two goals. The first, characterization of the reservoir geometry as input data for the interpretation of the depletion experiment, will be realized. Secondly, this survey was to be the first of a two-survey experiment to evaluate the ability of a pair of surveys, before and after reservoir depletion, to detect the portion of the reservoir yielding fluids. The performance of a second survey is in doubt because the production well failed prematurely.
MODELING SHELF STORM BEDS: CONTROLS OF BED THICKNESS AND BEDDING SEQUENCE
Authors: NIEDORODA ALAN WILLIAM , SWIFT DONALD J.P. , THORNE JULIANA. 
Published: October 2019

ABSTRACT
Shelf facies are defined by stratification and grain size characteristics. Most shelves are storm-dominated, and their strata are commonly storm beds (event strata). Strata that form on the less extensive tide-dominated shelf sectors are technically periodites rather than event strata. However, they are structurally similar, and can be viewed as being formed by very regular events.
The variables controlling shelf storm bed formation are the time sequence of events and the time-averaged value of fluid power expended by waves and bottom currents, grain size of the available sediment, sedimentation rate, and the rate of biological mixing of the sediment. Within the last decade, our understanding of shelf sediment dynamics has reached a point where it is possible to present a simple numerical model for building storm strata sequences. The model uses extreme event statistics to bridge the gap between the dynamical time scale of strata formation and the stratigraphic time scale of strata accumulation. Our application of the model produces shelf storm beds with scales similar to observed deposits of the same type. Because such agreement is unlikely to be simply fortuitous, it supports, but does not prove, the appropriateness of the underlying marine sediment dynamic theories and the overall analytical methods.
Numerical experiments conducted with the model show that storm beds may form across the continental shelf, with most of the activity in water depth of 50 m and less. Within this region, shelf facies comprise a continuum whose main trend extends from a fragmentary record of coarse, thick-bedded, extreme event deposits on the upper shoreface to a nearly continuous record of fine, thin-bedded deposits on the central or outer shelf. This trend may be a response to decrease in the available fluid power (directly, or as a consequence increasing depth), to increasing grain size or sedimentation rate, or to some combination of these factors. Deposits from relatively common storms (e.g., the annual extreme event) are preserved when there is a moderate to high net accumulation rate. The water depth at the time of deposition has a major influence on the thickness and statistical pattern of storm beds. This effect shows promise of providing a technique for mapping water depths for ancient shelf deposits.
POSSIBLE PRE-JURASSIC ORIGIN FOR SOME JURASSIC-RESERVOIRED OIL, CASS COUNTY, NORTHEAST TEXAS
Authors: Schumacher Dietmar , Parker Rose Mary 
Published: October 2019

ABSTRACT
Discoveries of light oil and gas in Jurassic Norphlet sandstone in northeast Texas in 1983 renewed exploration interest in the petroleum potential of pre-Smackover Jurassic and older formations in the region. The Norphlet oil from Colville field resembles Smackover oils and condensates in gross geochemical characteristics, however, its carbon isotopic composition (-29.7) clearly distinguishes it from Smackover oils (-22 to -26). Furthermore, selected isoprenoid and gasoline-range ratios show a strong terrestrial component in this Norphlet oil relative to Smackover oils, and suggest a pre-Jurassic origin.
What are the possible sources for this pre-Smackover oil? Various authors have speculated that organic-rich lacustrine shales might be present within the Triassic Eagle Mills Formation. Although such deposits are poorly documented in the Gulf Coast, lacustrine petroleum source rocks do occur in Triassic-Jurassic rift sequences in the eastern United States. The carbon isotopic composition of oil stains and bitumens from these rocks (-28 to -31) compares favorably with that of the Norphlet oil from Colville field. Another possible source for this oil maybe Late Paleozoic strata, chiefly Pennsylvanian shales and carbonates, that underlie the Triassic and Jurassic in much of this area. Although there are no reported hydrocarbon shows or documented source rocks in the Pennsylvanian of northeast Texas or adjacent Louisiana and Arkansas, Pennsylvanian oils from productive areas in Texas, Oklahoma, and Alabama are isotopically indistinguishable (-29 to -31) from Norphlet and Triassic oils.
We have not yet identified the source of this geochemically distinctive Norphlet oil, however, the available data strongly suggest a Triassic or Late Paleozoic origin. Confirmation of this conclusion could have considerable exploration significance in this mature basin and might yet lead to a successful Triassic or Paleozoic play in the region.
CHEMICAL AND ISOTOPIC EVIDENCE OF THE ORIGIN OF HYDROCARBONS AND SOURCE POTENTIAL OF ROCKS FROM THE VICKSBURG AND JACKSON FORMATIONS OF SLICK RANCH AREA, STARR COUNTY, TEXAS
Authors: Tanner Jeffrey A. , Fuex Anthony N. 
Published: October 2019

ABSTRACT
Wet gas-condensate with a minor amount of oil is produced from Frio and Vicksburg Formation sandstones in the Slick Ranch area, Starr County, Texas. Molecular and carbon isotopic analysis of natural gas and crude oil samples from this area indicate the hydrocarbons to be primary (i.e., unaltered), mature to very mature products derived from a mix of marine and terrestrial organic matter. On the basis of carbon isotope ratios of the gases, ethane and propane, the Slick Ranch gases were generated within the oil window in a maturity range up to VR 1.5%. Further, the carbon isotope ratios of these gases appear to be representative of gas generated from source rocks containing a predominance of humic organic matter with a minor amount of sapropelic organic matter. Crude oils and condensates are high gravity (40 API), low sulfur (&lt; 0.20 wt %) samples, containing a great predominance of saturated hydrocarbons. Compositional variations of saturated hydrocarbons and carbon isotope ratios suggest that the liquids were generated from organic matter deposited in an open marine environment which received partially oxidized land-plant detritus.
Visual kerogen analysis of the lower Vicksburg and Jackson Formations shows a predominance of gas-prone vitrinite disseminated within a thermally mature source facies. These data, in addition to oil-rock geochemical correlations, suggest that the Jackson shale is the most likely source for the majority of the hydrocarbons trapped in the study area. Lower Vicksburg shales appear to have generated minor amounts of natural gas.
