Optical methods are now often used in the measuring technology. These methods have the great advantage that the inspected objects are measured contactlessly with a high repetition rate. The obtained data can be evaluated in almost real-time or in post-processing. This allows the reckoning of deformations in real-time, as well as the three-dimensional representation and the documentation of the whole process of deformation.
Deepwater and ultradeepwater completions employ numerous hydraulic control lines for operating downhole equipment as the primary method of actuation or as back-up systems for control and actuation. Incorporating a completion system with an in-well lift, i.e., electric submersible pumps (ESPs), increases the number of electrical lines that are needed for operation. The total number of control and electrical lines maximizes the number of hydraulic and electrical lines that can be terminated back to the tubing hanger and wellhead. On surface, managing and running the numerous control lines can be daunting. Weight and size limitation and available rig floor, deck, and sub-deck space must be considered when planning placement of reeled lines, back-up systems, and preparation of supporting systems for spooler and reels.
In this paper we discuss the planning and execution of an installation test conducted in close collaboration with an operator. This stack-up test was conducted to determine whether a completion system incorporating a dual canned ESP system with multiple control lines can be efficiently and safely deployed in a deepwater, high-pressure/high-temperature (HPHT) environment.
The completion system uses numerous hydraulic control lines, tubing encapsulated conductor (TEC) lines, and ESP electrical cables to support the various downhole completion equipment systems. The control lines and cables are various sizes and shapes, further complicating their manageability. Testing was successfully performed in a 500-ft test well on a land rigand the equipment and processes used were deemed scalable to a drillship operating in deep water. Results of the test suggest that safely deploying a dual canned ESP system in a deepwater well is possible. Doing so would bring increased revenue from the additional years of production enabled by the dual canned ESPs.
Commission VI, WG VI/4 KEY WORDS: UAV, Mobile Mapping, Laser scanning, IMU, low-cost
ABSTRACT:The research project with the working title "Design and development of a low-cost modular Aerial Mobile Mapping System" was formed during the last year as the result from numerous discussions and considerations with colleagues from the HafenCity University Hamburg, Department Geomatics. The aim of the project is to design a sensor platform which can be embedded preferentially on an UAV, but also can be integrated on any adaptable vehicle. The system should perform a direct scanning of surfaces with a laser scanner and supported through sensors for determining the position and attitude of the platform. The modular design allows his extension with other sensors such as multispectral cameras, digital cameras or multiple cameras systems. .
The research project "Development of a Mobile Mapping System for multi-purpose applications composed of a low-cost inertial measuring unit, a GNSS receiver and a close-range LIDAR" consists on considerations about the design of an aerial and a sensor platform, which can also be used separately. The aim of the project is the development of a measurement platform, which performs a direct scan of the Earth's surface by means of measurements with a laser scanner supported by several sensors to determine their position. The geo-referencing of the data will initially take place in post-processing.
El Lugar de Interés Geológico de Jarama VI es un abrigo rocoso que contiene una secuencia litoestratigráfica formada por cinco unidades sedimentarias del Pleistoceno superior, tres de las cuales presentan restos arqueológicos del Paleolítico medio con una edad mayor de 50 ka BP. En una de ellas se ha recuperado un resto óseo de Homo neanderthalensis. Para preservar toda la información analógica disponible sobre este LIG y contar con un registro digital del mismo, hemos llevado a cabo tres proyectos consecutivos cuyos objetivos se centraron en la obtención de una cartografía digital de detalle del yacimiento y su entorno, la digitalización del registro arqueológico analógico de las excavaciones realizadas entre 1989-1993, la creación y cumplimentación de una Infraestructura de Datos Espaciales y la realización de un análisis microespacial y estadístico del yacimiento, a la vez que hemos llevado a cabo un estudio hidráulico de las paleoinundaciones observadas en su registro sedimentario.
