The objective of this study is to determine hydrate formation conditions of a multicomponent polymer based drilling fluid. During the study, experimental work is carried out by using a system that contains a high-pressure hydrate formation cell and pressure-temperature data is recorded in each experiment. Different concentrations of four components of drilling fluid, namely potassium chloride (KCl), partially hydrolyzed polyacrylicamide (PHPA), xanthan gum (XCD) and polyalkylene glycol (poly.glycol) were used in the experiments, to study their effect on hydrate formation conditions.

This study examines the issues of collaboration and competition in the context of oil and gas sector organizations. The convergence of economics and organization science literatures suggests a connection between the prevalence of extraorganizational exchange and the role of technology in driving innovation and growth. Specifically, the role of collaboration as a strategy for increasing the returns to technology and providing competitive advantage is explored in this research. / Two questions were advanced to examine the framework. The first investigated the relationships between a set of organizational characteristics and collaborative success; four propositions were developed to test this question. The second issue explored how organizations manage collaborative-competitive tensions in an environment characterized as fiercely competitive and marked by widespread collaborative arrangements. / Using a qualitative research methodology, thirty face-to-face interviews were conducted with executives and senior-level managers from twenty-three companies over an eight-month period; a questionnaire was also used to gather the more objective information. The sample included diversified energy, exploration and development, pipeline and oil and gas service companies. The majority of firms were located in the Houston, Texas area. / The most important implications of the study pertain to innovation and organizational change issues. Principal findings were that the ability to manage complex and multiple time frames was positively associated with an organization's level of collaborative capability, a construct that measured collaborative experience and expertise; organizational boundaries that are neither completely permeable nor fully defined were consistent with more successful collaborations; and the proposed direct relationship between collaborative capability and competitive advantage was only weakly supported. Further results indicate that three-fourths of the sample did not experience conflict between collaborative and competitive strategies, while those firms that noted tensions were confined to oil and gas service companies; and collaborative arrangements were motivated by three imperatives of capital intensity, competition and dependency, each of which led to distinct organizational outcomes.

The history and archaeology of the oil and gas industry has received little attention in cultural resource management. The sites of early exploration activity are being destroyed rapidly due, in part, to the fact that field archaeologists and historians have not been educated on the scientific and historical importance of this industry to the American culture. This thesis is an attempt to begin the education process. The document begins with an overview of the historical developments on a national level and in the State of Wyoming. Attention is then focused on the physical remains that can be found in the field with guidance on the identification, interpretation, and evaluation of the remains. The thesis concludes with the development of research, designs and avenues of future inquiry.

This paper determines the relationship between the crude oil price and the financial performance of International Oil Companies (IOCs) of the Eurozone during the last decade (from 2004 to 2013). This study is conducted around a multiple regression model with panel data with the financial performance ratios (ROA, ROE, Profit Margin) as dependent variables and the crude oil price as independent variables. A knowledge gap is visible since the crude oil price was never used as an independent variable in relation to the financial performance ratios of IOCs. In addition, the IOCs in the Eurozone have not been studied since most studies focuses on the United States and Asia. Moreover these studies focus on stock returns rather than financial performance. The research follows a quantitative approach by assessing the relationship of the crude oil price with financial performance of IOCS during the 10-year period (from 2004 to 2013) for 11 companies from 10 countries. The purpose of the study is to determine the effect of the crude oil prices on the financial performance of oil producer companies on a 10-year period using a multiple regression model with panel data. The research question therefore is:What is the relationship between the crude oil price and the International Oil Companies’ financial performance in the Eurozone during the last ten years (2004-2013)?The empirical results show that the crude oil price has a negative relationship with the financial ratios and that the crisis had an impact during that time period on the financial performance of the IOCs. It is also noted that the debt level and the size of IOCs have a strong relationship with their financial performance. The findings on the relationship between the crude oil price and the financial performance of IOCs are opposed to the results of Dayanandan & Donker study (2011). The findings of this research paper are relevant for investors and researchers looking to assess the performance of the Oil & Gas Industry so as its determinants.

In this study, the structure sensitivity of hydrogen, oxygen and carbon monoxide adsorption was investigated by changing the metal particle size of Pt/Al2O3 catalysts. 2 % Pt/Al2O3 catalysts were prepared by incipient wetness method / the particle size of the catalysts was manipulated by calcining at different temperatures. The dispersion values for the catalysts calcined in air at 683K, 773K and 823K were measured as 0.62, 0.20 and 0.03 respectively. The differential heats of adsorption of hydrogen, carbon monoxide and oxygen were measured using a SETARAM C80 Tian-Calvet calorimeter. No structure dependency was observed for hydrogen, carbon monoxide or oxygen initial heats of adsorption. The adsorbate:metal stoichiometries at saturation systematically decreased with increasing particle size. Hydrogen chemisorption sites with low and intermediate heats were lost when the particle size increased. On the other hand, oxygen and carbon monoxide initial heats and adsorption site energy distributions did not change appreciably with the metal particle size.

The aim of this experimental study is to investigate the inhibitive properties of polyglycol and polyglycol+KCl aqueous solutions on hydrate formation, which causes serious fluid flow problems, especially during deepwater drilling operations. As the petroleum industry continues to search oil in deeper and deeper seas, the possibility of facing hydrate problems during drilling operations increases because of the suitable conditions for hydrate formation. The main goal of this study is to investigate the hydrate inhibition capacity (thermodynamic and/or kinetic inhibition) of polyglycol and KCl which are mainly used in drilling fluids for shale inhibition and wellbore stability. A high pressure hydrate forming reactor is used to form and dissociate methane hydrate from aqueous solutions of polyglycol and polyglycol+KCl. In total 10 experiments were carried out, 5 of them with 0%, 1%, 3%, 5% and 7 % by volume of polyglycol solutions (Group-A experiments). The remaining 5 experiments (Group-B) had 8% by weight of KCl in solution in addition to the same polyglycol concentrations of Group-A experiments. Among the two chemicals tested for their hydrate inhibiting potentials, polyglycol did not exhibit any thermodynamic inhibition capacity while KCl was observed to have the ability of hydrate inhibition thermodynamically. On the other hand, increase in polyglycol concentration at constant KCl concentration (Group-B) increases the hydrate formation depression capacity of KCl. Polyglycol inhibits methane hydrate formation kinetically. The higher the polyglycol concentration in aqueous solution, the lower is the initial rate of methane hydrate formation (corresponding to first 15 minutes of hydrate formation). On the other hand, there exists a slower change of methane hydrate formation rate as polyglycol concentration increases.
