EXPERIENCE, NEIGHBHORHOODS, AND HABITATS: BREEDING DISPERSAL OF MALE BLACK-CAPPED VIREOS (VIREO ATRICAPILLA)
(2019-08-01)1. Mechanisms driving breeding dispersal are complex and potentially interactive. These mechanisms are of general interest because dispersal strongly links individual fitness to population dynamics. We examine the ... -
Experiences of Social Isolation in Rural Communities: A Multidisciplinary Approach
(2024-05-10)Rural communities often struggle due to a lack of funding, resources, and support, which can put residents at risk for adverse experiences. Merely living within a rural area is considered an influential contributing risk ... -
Experimental Analysis of Centrifugal Downhole Separators in Boosting Artificial Lift Performance
(2021-12-18)Gas evolution and expansion is a natural phenomenon in oil and gas wells. However, gas is detrimental to pumping artificial lift (AL) systems, causing incomplete pump fillage and reduced pump efficiency in oil wells. Pumping ... -
Experimental and numerical study on separation of solid-liquid slurries
(2020-12)The separation of solid-liquid slurries, as a critical stage of a novel zero-liquid discharge (ZDL) eutectic-freeze desalination method, is the focus of this thesis. Firstly, various technologies for separation of solid-liquid ... -
EXPERIMENTAL CHARACTERIZATION OF BRINE IN CRUDE OIL EMULSIONS AND ITS PERFORMANCE IN ARTIFICIAL LIFT SYSTEMS
(2018)Understanding the behavior of water in oil emulsions can prevent flow assurance problems and the conditions at which these two fluids can mix. The stability and rheology of water in crude oil emulsions was studied for three ... -
Experimental Determination Of Oilfield Cement Properties And Their Influence On Well Integrity
(2017-12)Oilfield cements are a key element in well construction, during the operational phase of a well, and after its abandonment. Hydrocarbon, geothermal, gas storage and carbon sequestration wells make use of oilfield cements ... -
Experimental Evaluation of a Centrifugal Packer-Type Downhole Separator
(2019)With the ever-increasing decline in production of oil wells, application of artificial lift techniques is becoming inevitable. Beam pumps and electrical submersible pumps are two of the most common artificial lift methods ... -
An Experimental Investigation into Using Electro-Chemical Properties to Measure Permeability in Low Permeability Formations
(2016-12-16)Permeability is one of the most important property in the study of rock formations. Different permeability measurement techniques have been used in the industry, some of which are based on modelling while others on ... -
Experimental Investigation of a Novel Working Fluid for Heat Extraction In Geothermal Wells
(2023-05-13)The exponential increase in the global atmospheric carbon dioxide has spurred research interest in the exploration and maximization of renewable energy exploits. This interest has in turn inspired the growth of the geothermal ... -
Experimental investigation of elastomer performance for underground hydrogen storage wells
(2023-05-15)The "Power-to-Gas" concept is vital in the envisaged Hydrogen Economy as it ensures sustainability and energy security. The process involves converting surplus energy from various sources like conventional fossils, wind ... -
Experimental Investigation of High Temperature Effect on Lost Circulation Materials for Geothermal Applications
(2021)Sustainable energy generation is crucial to meet the energy demands in the 21st century while keeping the implications of future challenges at its core philosophy. A geothermal power generation plant is one of such avenues ... -
Experimental Investigation of Molecular Hydrogen Effect on Cement Related to Well Integrity for Underground Hydrogen Storage
(2022)Underground Hydrogen Storage (UHS) in the subsurface is an alternative to overcome limitations associated with a fluctuating production of renewable energy sources. The excess energy produced can be converted to hydrogen ... -
Experimental investigation of polymer-based lost circulation materials for fluid loss treatment under high temperature using additive manufacturing
(2023-05-13)Lost circulation continues to be one of the most troublesome problems encountered during drilling. The financial cost of lost circulation in geothermal drilling can rise to 15% of the total drilling cost. A corrective ... -
EXPERIMENTAL INVESTIGATION OF PROPPED FRACTURE CONDUCTIVITY
(2018-05)Hydraulic fractures act as conduits connecting a wellbore to nanodarcy permeability unconventional reservoirs. Proppants are responsible for enhancing the fracture conductivity and help in maintaining high production rates. ... -
EXPERIMENTAL INVESTIGATION OF SHALE-DRILLING FLUID INTERACTION AND ITS IMPLICATIONS ON DRILLING EFFICIENCY
(2020-05-08)The United States (US) energy consumption is growing at an amazing rate. The high demand in oil and gas has created a surge in shale exploration, drilling, and production. Shale formations have become a source of attraction ... -
Experimental Investigation of Synthetic and Microbial Surfactants for Enhanced Oil Recovery in Bone Spring Sandstones
(2022-12-17)Surfactants have been used to increase hydrocarbon recovery to meet the increasing demand for oil and gas. This mechanism of using surfactants reduces the Interfacial Tension (IFT) at the fluid/fluid interface and wettability ... -
