Essential Control To Environmental Regulations For Oil And Gas Industry: Spotlight On Drilling Processes In Lebanon, Rami Harkouss

BAU Journal - Science and Technology

At present, environmental legislation bounds the drilling operators in drilling wastes removal. The rapid increasing sensitivity of drilling waste management forced many countries to develop environmental guidelines for their drilling operations. This research studies some sorts of waste produced during upstream petroleum activities, particularly while drilling. After that, many hazards and impacts on the environment are addressed, as well as their principal treatment techniques. This paper gives a modest and theoretical vision over the present environmental standard and waste management design, realized at a universal scale. Studies show that performance fluid management and total fluid management are highly recommended in …

Biogas Production Of Lignite And Variation Characteristics Of Cations In Liquid Phase System, Zhao Han, He Huan, Wang Jiangze, Song Yanli, Niu Jianglu, Chen Linyong, Guo Xin, Liu Jian, Guan Jiadong, Yuan Xuefang

Coal Geology & Exploration

Liupan Shan lies between the Tibetan plateau and Ordos block and has been under the remote effect of the northeastward extension of the Tibetan plateau. The former research about the uplift of Liupan Shan mainly focused on the petrology, structural deformation or tectonic evolution study from the Cretaceous to early period of Cenozoic. However, the Late Pleistocene geological study closely connected with the human activities was rarely mentioned. In this study, we carried out systematic sedimentary research in the Qingshuihe basin adjacent to the Liupan Shan tectonic belt, re-determine the sedimentary sequence at first, then reverse the uplift history of …

Optimizing Raman Spectral Collection For Quartz And Zircon Crystals For Elastic Geothermobarometry, Mayara F. Cizina

Boise State University Theses and Dissertations

Raman microspectroscopy is widely used to identify and characterize organic and inorganic compounds. In the geosciences, Raman microspectroscopy has been used to identify mineral and fluid inclusions in host crystals, as well as to calculate pressure-temperature (P-T) conditions using mineral inclusions in host crystals, such as quartz-in-garnet barometry (QuiG). For thermobarometric applications, the reproducibility of Raman peak position measurements is crucial to obtain accurate P-T estimates. In this study, we explored how to optimize Raman spectral collection of quartz and zircon inclusions and reference crystals by monitoring machine stability and by varying spectral parameters. We also monitored a reference Hg …

Earthquake Nucleation In The Lower Crust By Local Stress Amplification, Lr Campbell, L Menegon, Å Fagereng, G Pennacchioni

School of Geography, Earth and Environmental Sciences

AbstractDeep intracontinental earthquakes are poorly understood, despite their potential to cause significant destruction. Although lower crustal strength is currently a topic of debate, dry lower continental crust may be strong under high-grade conditions. Such strength could enable earthquake slip at high differential stress within a predominantly viscous regime, but requires further documentation in nature. Here, we analyse geological observations of seismic structures in exhumed lower crustal rocks. A granulite facies shear zone network dissects an anorthosite intrusion in Lofoten, northern Norway, and separates relatively undeformed, microcracked blocks of anorthosite. In these blocks, pristine pseudotachylytes decorate fault sets that link adjacent …

Initial Measurements On The Effect Of Stress On P- And S-Wave Velocities In Olivine, Taryn Traylor

UNLV Theses, Dissertations, Professional Papers, and Capstones

It is well known that elasticity is a key physical property in the determination of the structure and composition of the Earth and provides critical information for the interpretation of seismic data. This study investigates the stress-induced variation in elastic wave velocities, known as the acoustoelastic effect, in San Carlos olivine. A recently developed experimental ultrasonic acoustic system, the Directly Integrated Acoustic System Combined with Pressure Experiments (DIASCoPE), was used with the D-DIA multi-anvil apparatus to transmit ultrasonic sound waves and collect the reflections. We use the DIASCoPE to obtain longitudinal (P) and shear (S) elastic wave velocities from the …

Simulating Hydrological Connectivity And Water Age Within A Coastal Deltaic Floodplain Of The Mississippi River Delta, Alexandra Christensen, Robert R. Twilley, Clinton S. Willson, Edward Castañeda-Moya

Faculty Publications

Located at the mouth of large rivers, coastal deltaic floodplains are important ecosystems for trapping sediment and removing excess nitrogen introduced to the river through agricultural and urban runoff. Hydrological connectivity (the percent of river channel water interacting with floodplain wetlands), water age (the time elapsed since water entered the system via the main river channel) and water temperature have strong impacts on the biogeochemical processes controlling the fate of sediment and nutrients at continental margins. A Delft3D hydrodynamic model was used to explore the role of river and tide forcings, hydrogeomorphology, and vegetation roughness on hydrological connectivity, water age, …

Climatic Influence On The Growth Pattern Of Panthasaurus Maleriensis From The Late Triassic Of India Deduced From Paleohistology, Elżbieta M. Teschner, Sanjukta Chakravorti, Dhurjati P. Sengupta, Dorota Konietzko-Meier

Journal Articles

Metoposaurids are representatives of the extinct amphibian clade Temnospondyli, found on almost every continent exclusively in the Late Triassic deposits. Osteohistologically, it is one of the best-known temnospondyl groups, analyzed with a wide spectrum of methods, such as morphology, morphometry, bone histology or computed modelling. The least known member of Metoposauridae is Panthasaurus maleriensis from the Pranhita-Godavari basin in Central India, being geographically the most southern record of this family. For the first time the bone histology of this taxon was studied with a focus on the intraspecific variability of the histological framework and the relationship between the observed growth …

Salt Marsh Dynamics In A Period Of Accelerated Sea Level Rise, Sergio Fagherazzi, Giulio Mariotti, Nicoletta Leonardi, Alberto Canestrelli, William Nardin, William S. Kearney

Faculty Publications

Salt marshes are dynamic systems able to laterally expand, contract, and vertically accrete in response to sea level rise. Here, we present the grand challenges that need to be addressed to fully characterize marsh morphodynamics. The review focuses on physical processes and quantitative models. Without predictive models, it is impossible to determine the future marsh evolution under accelerated sea level rise. In these models, one of the challenges is to resolve both horizontal and vertical dynamics within the same framework. Vertically, the marsh has to accumulate enough material to contrast rising water levels. Horizontally, marsh erosion at the ocean side …

Characterization Of An Acid Rock Drainage Microbiome And Transcriptome At The Ely Copper Mine Superfund Site, Lesley Ann Giddings, George Chlipala, Kevin Kunstman, Stefan Green, Katherine Morillo, Kieran Bhave, Holly Peterson, Heather Driscoll, Mark Maienschein-Cline

Chemistry: Faculty Publications

The microbial oxidation of metal sulfides plays a major role in the formation of acid rock drainage (ARD). We aimed to broadly characterize the ARD at Ely Brook, which drains the Ely Copper Mine Superfund site in Vermont, USA, using metagenomics and metatranscriptomics to assess the metabolic potential and seasonal ecological roles of microorganisms in water and sediment. Using Centrifuge against the NCBI “nt” database, ~25% of reads in sediment and water samples were classified as acid-tolerant Proteobacteria (61 ± 4%) belonging to the genera Pseudomonas (2.6-3.3%), Bradyrhizobium (1.7-4.1%), and Streptomyces (2.9-5.0%). Numerous genes (12%) were differentially expressed between seasons …

Investigation Of Environmental Impacts On Sandstone Blocks At Luxor Temple And Concepts For Conseration, Dr. Elashmawy Abd -Elkareem Ahmed

Journal of the General Union of Arab Archaeologists

(En) Sandstone blocks were used in the construction of Luxor temple. However, they, especialy cement materials, were at a great risk because of being affected by various deterioration factors. Groundwater started to rise in and around the temple, causing serious deterioration aspects of the blocks. Therefore, the current study was conducted to focus on the role of pores and cement regarding the deterioration process of sandstone blocks in the temlpe. In order to conduct systematic investigation, it adopted SEM – EDX, PLM and XRD. Also, physical and mechanical properties were examined to evaluate the components of the sandstone, under the …

Integrating Detailed Petrography, Geochemistry, And Mineralogy To Elucidate Extensive Early Diagenesis In The Eocene Carbonates Of Qatar, Brooks H. Ryan

Dissertations

Eocene carbonates comprising the Umm er Radhuma (UER), Rus, and Dammam Formations, cover 80% of the surface and extend >300 m into the subsurface of Qatar. These rocks record marine sedimentation in shallow sub-tidal to restricted settings. Despite undergoing only shallow burial (<1000 m), extensive diagenetic alteration has occurred. Given that little work on this topic has been published previously, the objectives of this work are to document diagenesis in the Eocene, and to integrate petrography, mineralogy, and geochemistry to delineate the timing and environments of diagenesis of these Eocene carbonates. Detailed petrographic data show that dolomitization occurred early in the UER, before the formation of diagenetic chert, palygorskite, pyrite, calcite, and gypsum cements. Bulk dolomite δ¹⁸O values, coupled with clumped isotope-derived (Δ47) temperatures and dolomitizing fluid δ¹⁸O values, suggest dolomitization took place in near-normal marine fluids, perhaps during shallow burial. These data challenge the current paradigm of large-scale, top-down hypersaline reflux dolomitization in the UER. Associated depth trends of increasing crystal size and with increasing stoichiometry and cation ordering …

Mountainous City, Yixuan Hu

Masters Theses

My thesis studies how glaciation and vegetation systems define the landscapes of Mount Gongga, and asks how these and their modes of relation and zonation might provide a model for more sustainable and fully adaptable structures to support urbanism. Using mountain systems as the metaphor, I proposed a mountainous city model focusing on efficient urban ecosystems and spontaneous human activities. By the methods of deconstructing and mimetic modeling, they triggered a series of rethinking about the formation and relation of urban spaces. The mountainous city has four distinctive vertical layered zones, which integrated with hydrological and ecological systems and vertical …

Clearing The Clouds: Extracting 3d Information From Amongst The Noise, Alexander Fafard

Theses

Advancements permitting the rapid extraction of 3D point clouds from a variety of imaging modalities across the global landscape have provided a vast collection of high fidelity digital surface models. This has created a situation with unprecedented overabundance of 3D observations which greatly outstrips our current capacity to manage and infer actionable information. While years of research have removed some of the manual analysis burden for many tasks, human analysis is still a cornerstone of 3D scene exploitation. This is especially true for complex tasks which necessitate comprehension of scale, texture and contextual learning. In order to ameliorate the interpretation …

Regulation Of Large Dairy Farms In Karst Regions Of The United States, Jesse J. Richardson Jr.

Sinkhole Conference 2020

During the past several years, an increasing number of large dairy farms have located, or proposed to locate, in karst terrain in the Midwestern United States. The large amounts of manure produced by such dairy farms proves especially problematic to groundwater in karst terrain. Controversies have erupted in Minnesota, Illinois, and Wisconsin, among other states. In response to the proposed dairies, citizen groups have filed a number of lawsuits against the dairy operators, the dairy industry has filed lawsuits against state agencies, and states have enacted heightened regulations for dairy operations in karst. The majority of the debates have centered …

Lower Jurassic Fluvio-Lacustrine Deposits Of The Glen Canyon Group, Sw Utah, Samuel A. Abdala

Loma Linda University Electronic Theses, Dissertations & Projects

Lower Jurassic fluvio-lacustrine deposits of the Kayenta Formation and Whitmore Point Member reveal past climatic and tectonic conditions in SW Utah. Fluvial overbank deposits and sparse channel belts characterize the Kayenta’s intermittent fluvial system. Reconstructed dune morphology matches that of modern rivers. Downstream bar accretion, as in braided channels, is indicated by numerical reconstruction. Vertical succession of cross-set thickness and grain size shows covariance drop up-section. This, along with a decreasing sand/mud ratio of sandstones suggests that suspended load increased up-section. The Kayenta vertically progresses from poorly-channelized sandsheets to wide channel-fills. Paleohydraulics-derived sandstone body widths are smaller than those measured …

A Thumb On The Scale: Chinese Investment And Influence In Ecuador And Colombia, Christina Pendergrast

Honors Theses

Over the past two decades, Chinese involvement in the developing world has increased dramatically, raising concerns over the intentions behind the provision of development packages. Critics have accused China of a practice known as debt-trap diplomacy, a method of ensnaring less developed nations by providing more loans than those nations have the ability to feasibly pay back. While China denies that their loan and investment packages are provided with any ulterior motive, the influence held by an investor like China has the potential to impact these partner countries for decades to come. In light of the scope of China’s role …

Characterization Of Surface Karst Using Lidar And Field Traverses, Fort Hood Military Installation, Coryell County, Texas, Heather Jaclyn Dailey

Electronic Theses and Dissertations

The Fort Hood Military Installation is a karst landscape that has been significantly altered for training exercises that include heavy vehicle maneuvers and simulated combat. Traditional karst surveys are often time-consuming and require extensive field analyses to adequately characterize large areas. Bias is given to areas that are most easily accessible and false negatives are common. Previous studies conducted in the eastern and western portion of the base have understated the abundance and spatial distribution of karst, particularly in the western portion.

This study used field traverses and 0.5-meter Light Detection and Ranging (LiDAR) data to characterize surface karst depressions, …
