The oil and gas industry has long recognized the inadequacy of existing theories to predict the behavior and outcome of some hydraulic fracturing treatments. Data sets compiled over the last two decades are incompatible with the conventional picture of a single planar hydraulic fracture. These data sets include field studies, laboratory studies and theoretical models. Several field and laboratory observations show very complex fracture paths, multisegmented fractures, branching, asymmetry and the presence of multiple fractures. The purpose of this study is to investigate the pressure behavior of systems containing near wellbore and far field multiple vertical fractures. This objective is achieved by using two analytical models. These newly developed models are used to explore pressure behavior and to generate type curves using the pressure derivative concept. The first new analytical model considers a composite reservoir with the inner zone containing an arbitrary number of dendritic multiple hydraulic fractures and the outer zone showing natural fractures. Transient pressure, derivative and flow regimes of the fractured system are investigated using this model. This study also uses a numerical model to calibrate and validate the analytical model. Pressure transient behavior of multiple fractures is modeled using a full field model (FFM) with a detailed Cartesian local grid refinement (LGR) around the fractures. The model was calibrated and validated using the case of two wing fractures at 180o. Simulations of the two types of multiple fractures, dendritic and parallel, validate some results of the analytical solutions. The TDS technique is also used to analyze the linear and pseudo-radial flow regimes in order to find fracture length, angle between fractures, fracture conductivity and several conventional reservoir parameters, e.g. permeability, wellbore storage and skin.  Multiple fractures create more surface area in direct communication with the wellbore. As a consequence, a greater volume of fluid can be produced from the wellbore per unit time. While fracture treatments continue to be designed using the best tools and techniques available, geometry estimates from fracture models have been difficult to verify. Pressure transient analysis is one of the fracture diagnostic techniques available to fill this knowledge gap, improving our understanding of hydraulic fracture behavior. It is an excellent calibration tool because it lets us evaluate the effective length of the fracture, and determine the appropriate length to use in history matching. Also, regardless of the application, identifying and understanding fracture complexities can lead to improved treatment designs, better completion strategies, and the potential for significant economic rewards through improved well performance and/or reduced completion cost.

The dissertation develops an analysis of how speed (as a quotient of space and time) has been described as a positive attribute and an adequate solution to industrial development, cities' efficiency and, in general, citizens' well being, while time?space compression as an underlying process has been widely studied but rarely acknowledged in policy. It analyses the evolution of the discourse on speed from before Bogotá’s BRT system “TransMilenio” (in 1996) and until recently (in 2006) and how it may have influenced such discourse. It questions the usefulness of speed and some transport interventions in Bogotá, and how other more structural measures may be taken to solve a city’s ills. The dissertation provides a conceptual framework on time, cities and time?space compression and speed, followed by a description of Bogotá and TransMilenio and results of the study. It ends with a discussion on the role of speed in Bogotá, the evolution of transport planning, and time?space compression and how it relates to the case in question. 

The ambient noise analysis field has several methods used to study Microzonation with the aim to mitigate the risk of damage in structures. A new method to study seismic noise was developed by Wassermann et al., 2016. The novel technique uses the existent relation between the transverse component of acceleration and the vertical component of rotation generated by Love waves to retrieve their inherent dispersive character (Kurrle et al., 2010). The advantage of this implementation is that it only needs two instruments to measure acceleration and rotation in the same location, making it easy to deploy as the H/V spectral ratio. Moreover, the information retrieved is easier to interpret than the aforementioned technique. In addition, the same aspects of the wavefield retrieved from array echniques such as F-K and SPAC could be recovered. This thesis aims to complement this method by studying Rayleigh waves and using the implicit relation between the vertical acceleration and the horizontal rotation or tilt generated by them. We use a statistical process to build dispersion curves for this kind of wave, finding its phase velocities in the medium and its arrival direction. Our findings indicated that the new implementation overestimates the phase velocities, which may be due to the fact that a weak-rotational motion sensor was not available, and the array-derived rotation method was used. Hence, this led to high uncertainties in the measure of rotation and also to lower magnitudes of its horizontal components with respect to the vertical one. The method seems reliable to find the back azimuth of noise generated by Rayleigh waves and complements well the findings of the Love-wave technique previously mentioned.

Usually, an actuary would begin by trying to study a particular consumer insurance pool. In this work, I am working on Colombia and soon, I struggled in having complete and precise information. Indeed, it is a recurrent issue for actuaries studying most emerging countries. The next step would be to estimate the risks an insurance company will have to face in order to create profitable products. I was interested in studying Climatic risks and, since Colombia's weather is interesting. I decided to study the floods in Colombia. Colombian weather is ruled by still unpredictable and random events: El Niño and La Niña that bring droughts and floods. Once again, I quite struggled in having reliable insurance information about the floods since this risk has never been surveyed separately from the overall house damages before 2010. From 2010 to 2012, because of the frequency and the importance of the floods, insurance companies have been trying to study the cost of climatic catastrophes but it was not profitable enough for them to keep on. Indeed, there are not enough people subscribing to house insurances for it to be profitable. Hence, I did not work only on 2010-2012 data because it does not allow me to stand back enough. I worked with the overall house damages data. Finally, from the two previous analysis, an actuary have to adapt his product to the consumer market.
