My work made a strong impact on the shape and direction of green cities and I’m a much sought after as Architect Consultant on a wide variety of planning cities, of course is analyzing of topics sustainable on human dimension around of the region and habitat. I seek to contribute to further promote international advisory bodies, scientists and universities to the Development of Ecological Design and Planning on climate change Environmental Problems within of scientific societies.

ABSTRACT Drilling automation is the control of the drilling process by automatic means, ultimately reducing human intervention to a minimum. The concept of automating the drilling process has generated considerable interest, yet there is a lack of agreement on exactly what it is, what it entails, and how to implement it. As with industrial automation in the 1990s, the adoption of open standards enabling automation will have a significant impact on the underlying business model. In the oilfield drilling industry, the business model describes the relationship between operator, drilling contractor, service company, and equipment supplier. The goal of drilling systems automation is to increase productivity and quality, improve personnel safety, and effectively manage risk. Principal drivers of drilling automation include well complexity, data overload, efficiency, repetitive well manufacturing, access to limited expert resources, knowledge transfer due to the exodus of skilled employees, and health, safety and environmental concerns. With so many drivers, and their potential economic benefits, it is understandable that there are many automation related initiatives within the industry. Drilling through geopressured, possibly erratic lithologies, to a remote and possibly poorly defined target in a safe manner is not a simple task to automate. It is challenging. Drilling automation focuses on the drilling system and drilling operations, which entail combining various sub-systems, including the downhole BHA and its measurement and active components, the drillstring, fluid, and drilling rig and its sub-assemblies. Operations include conventional overbalanced, managed pressure, and underbalanced drilling operations, and their various procedures, such as tripping and making connections. This paper examines and defines drilling systems automation, its drivers, enablers and barriers, and its current state and goals. In particular, the paper looks at the vision of drilling systems automation, and the role played by open collaborative initiatives among all segments of the drilling industry. Although commitment to automation by the drilling industry appears by many to lag other major industries, there are segments of the drilling industry that have reached a high level of automation on a commercial basis. There is also significant collaboration among interested parties in creating a standardized, open environment for data flow to foster the development of systems automation.

El presente documento hace referencia a la teoría del medio Ambiente y de Sustentabilidad para construir una sociedad con calidad de vida en armonía con su entorno y que genere un desarrollo sostenible para la investigación interdisciplinar con la Universidad de Guanajuato, un compromiso fundamentado sobre el conocimiento metodológico de CIUDAD EDUCADORA PARA LA SUSTENTABILIDAD, hacia el quehacer pedagógico de las actividades de aprendizaje de un modelo educativo universitario. Procuro dejar en la institución un expediente inédito teórico a llenar el vacío que hasta ahora existe en la materia, y lograr una transversalizacion sobre la forma de integrar en los programas educativos (PE) sobre la ciudad y Medio Ambiente Sostenible.

La de Edgar Morin es, qué duda cabe, una aventura intelectual. Extraña asociación la de estos dos términos. Lo intelectual evoca a la razón, al orden, a lo científico y, bien estructurado, a lo sesudo y alejado del riesgo. Aventura, en cambio, es el nombre de la pasión, del libre juego resistiendo la asfixia impuesta por las reglas, de lo impulsivo y espontáneo, de lo impredictible. La síntesis fértil, tensa pero creativa, de esos términos es, no solamente un hilo conductor de la ya monumental obra teórica de Edgar Morin, sino también una cualidad de su trayectoria personal. Su obra debe, en consecuencia, ser entendida no sólo en términos de su contenido sino del proceso productor. Es sobre ese proceso que Morin ha meditado muchas veces en un intento de adivinar la forma oculta de su búsqueda, una búsqueda que, como todos los destinos humanos, como lo pensaba Jorge Luis Borges, es una configuración única, diseñada tal vez por los pasos que cada uno de nosotros urde en un laberinto incalculable, y condensable en una ci-
secreta, un «aleph», al que a veces creemos vislumbrar ( como Einstein pensaba que pasa, ocasionalmente, con el sentido de lo humano) pero nunca logramos capturar plenamente.

La incorporación de la dimensión ambiental en los métodos históricos de análisis es todavía incipiente. El estudio de la historia se deja interrogar escasamente por las coyunturas del presente y, en ocasiones, se sumerge en el pasado como refugio idílico contra las condiciones actuales de existencia. Puede decirse, en general, que las grandes corrientes historiográficas han surgido como movimientos románticos de retorno o como idealizaciones míticas del pasado ancestral, para proponerlo como paradigma a las condiciones del presente. Tito Livio lo expresaba con esta sincera confesión que sirve de prólogo al libro de Las décadas:
“Por mi parte, un provecho obtendré de este trabajo: el de abstraerme del espectáculo de los males que por tanto tiempo ha presenciado nuestro tiempo, ocupando por entero mi atención en el estudio de la historia antigua”.

Although generally seen as an economic or demographic phenomenon, urbanization is also a human ecological transformation on our thinking. Understand the dramatic climate change in the spatial and material relations that require human with the rest of nature is a key to community sustainability assessment (Noosphere).
