Abstract: There are several key important physics that are involved with development of unconventional reservoirs. In the primary production phase, selection of proper proppant/fluid type, retaining a good fracture conductivity, and accurate fracture modeling are some important steps, in the modeling of “development plans”. Inclusion of “geomechanics” as an important piece of physics, at different scale and complexity, is an important step within the reservoir modeling workflow. Classical reservoir simulation approaches are sometimes not the optimum solution for the large-scale class of problems, due to their complexity and computational cost. Also, some of the input for the modeling workflows, are operationally expensive (such as core sampling, hard well data and acquiring extensive number of well logs).
Inclusion of geomechanics into reservoir simulation frameworks are computationally very expensive, however geomechanics is an important key factor for unconventional reservoir related processes , such as hydraulic fracture modeling and modeling of IOR/EOR processes in unconventional reservoirs, and most importantly for safe operations and avoiding of geohazards (i.e. induces seismicity). This presentation will illustrate an interactive framework that aims at using different approaches to facilitate numerical inclusion of geomechanics into larger scale reservoir modeling workflows. This includes development and use of numerical proxies, use of different simulation discretization schemes such as streamline class of simulators, and ultimately use of Artificial Intelligence and Probabilistic based techniques for reservoir modeling.

Unconventional formations have become an increasingly important source of energy resources. Proper rock mechanic characterization is needed not only to identify the most promising areas for stimulation, but to increase our understanding of the sealing capabilities of cap-rock formations for carbon geological storage. However, shale assessment is challenging with current standard techniques. This research explores the index and rock mechanic properties of different shale specimens considered as source rocks for oil and gas (Eagle Ford, Wolfcamp, Jordanian, Mancos, Bakken, and Kimmeridge), and presents an in-depth analysis of tools and protocols to identify inherent biases. New test protocols proposed in this thesis provide robust and cost-effective measurement techniques to characterize unconventional formations; these include: 1) new energy methods to assess brittleness and brittle/ductile conditions in the field, 2) tensile strength analyses to determine anisotropy in unconventional formations, 3) Coda wave analysis to monitor pre-failure damage evolution during compression, and 4) a combination of index tests to anticipate complex characteristics, which include high-resolution imaging, hardness, and scratch tests. Experimental results combined with extensive databases provide unprecedented information related to the mechanical behavior of shale formations needed for the enhanced design and analysis of geo-engineering applications. Calcareous shales display strong interlayer bonding and lower compressive strength anisotropy than siliceous shales. Tensile strength anisotropy is more pronounced than in compressive strength and reflects bedding orientation and loading conditions that affect fracture propagation and ensuing failure surface topography.

In fact, such technologies could virtually quantify the transition of an organism from being "healthy" to being "diseased". This can open to the possibility of achieving the earliest possible diagnosis. The integration of such bioelectronic sensors into a wearable platform would enable precision medicine to be implemented for the convenient monitoring of a person's health status. From a more fundamental point of view, the sensing of single-events faces the ultimate challenge of counting each molecule in a solution and opens to the study of rarer events that are otherwise lost in the background noise when the average most probable response of a population of countless molecules, is measured. Label-free single-molecule detection has been achieved so far by means of nanometric transducing devices that however, because of the small interaction cross-section, do not enable to measure a single molecule into a too large microliter volume. Several three-terminal organic bioelectronic structures have been proposed so far to address the needs for a variety of biosensing applications. The most popular ones utlized organic field-effect transistors immobilizing a layer of bio-recognition elements that are operated in an electrolyte that enables one to selectively detect both proteins and genomic analytes. These features along with the foreseen low-cost for their production, make them very appealing for point-of-care biomedical applications. This lecture aims at providing a systematic comparison between the potentiometric and amperometric electrochemical sensors and their organic bioelectronic transistors counterparts, showing why the latter can sense at the single-molecule level. Moreover, material-science and devices-operational aspects underpinning the sensing-principles of the assessed technologies critically prioritizing them according to scrutinized figures-of-merit such as limit-of-detection, need for a labelling-step and feasibility to assay biofluids.
