Estimation of reservoir fracture parameters, fracture orientation and density, from seismic data is often difficult because of one important question: Is observed anisotropy caused by the reservoir interval or by the effect of the lithologic unit or multiple units above the reservoir? Often hydrocarbon reservoirs represent a small portion of the seismic section, and reservoir anisotropic parameter inversion can be easily obscured by the presence of an anisotropic overburden. In this study, I show examples where we can clearly observe imprints of overburden anisotropic layers on the seismic response of the target zone. Then I present a simple method to remove the effect of anisotropic overburden to recover reservoir fracture parameters. It involves analyzing amplitude variation with offset and azimuth (AVOA) for the top of reservoir reflector and for a reflector below the reservoir. Seismic CMP gathers are transformed to delay-time vs. slowness (tau-p) domain. We then calculate the ratio of the amplitudes of reflections at the reservoir top and from the reflector beneath the reservoir. The ratios of these amplitudes are then used to isolate the effect of the reservoir interval and remove the transmission effect of the overburden. The methodology is tested on two sets of models - one containing a fractured reservoir with isotropic overburden and the other containing a fractured reservoir with anisotropic overburden. Conventional analysis in the x-t domain indicates that the anisotropic overburden has completely obscured the anisotropic signature of the reservoir zone. When the new methodology is applied, the overburden effect is significantly reduced. The methodology is also applied to an actual PP surface reflection (Rpp) 3D dataset over a reservoir in the Arabian Peninsula. Ellipse-fitting technique was applied to invert for two Fracture parameters: (1) Fracture density and (2) fracture direction. Fracture density inversion results indicate increased fracturing in the anticline structure hinge zone. Fracture orientation inversion results agree with Formation MicroImaging (FMI) borehole logs showing a WNW-ESE trend. This newly developed amplitude ratio method is suitable for quantitative estimation of fracture parameters including normal and tangential “weaknesses” (ΔN and ΔT respectively). Initially, inversion of conventional AVOA for ΔN and ΔT parameters indicates that the ΔN parameter is reliably estimated given an accurate background isotropic parameter estimation derived from borehole logging data. While ΔN parameter inversion is successful, inversion for ΔT parameter from Rpp information is not, presumably due to the dependence of ΔT estimation on many medium parameters for accurate prediction. The ΔN parameter is then successfully recovered when applied to the amplitude ratio values derived from synthetic data. It is important to recognize that ΔN parameter is directly proportional to fracture density and high ΔN values can be attributed to high crack density values. The ΔN parameter inversion is also applied to the amplitude ratios derived from real seismic data. This inversion requires fracture azimuth data input that is obtained from the fracture direction inversion using ellipse-fitting technique. The background Vp/Vs ratio. / text

<p>The research conducted has been undertaken to engage the stakeholders to explore the possibility of establishing workplace forums. The gains of workplace forums with respect to sharing decision making is a distinct advantage both business and labour seemingly do not realise because of a continued resolve to negotiate conditions of service annually exclusively. The research was undertaken by designing an interview questionnaire for distribution. The population for this research includes a cross section of employers from the industry in the Western Cape, parties to the Hairdressing Beauty and Cosmetology Bargaining Council, the Employers Organisation and the Employees Organisation or Trade Union. The criteria set for the questionnaire anticipate responses of respondents to the challenges before and after the possible incorporation of section 84 of the Act Finally the research results indicate that the parties to a collective agreement in this industry still gravitate towards distributive collective bargaining by negotiating salaries, wages and conditions of employment in Bargaining Councils.</p>

Recurring extreme events of nature challenge disaster-prone settlements in complex ways. Devastating property damages are one of the tests of survival for such settlements in both economic and social terms. It also provides unique opportunities to rethink the environment cleared by massive natural disasters. However, rebuilding for long-term resiliency is one of the least investigated areas, particularly when employing tacit knowledge in the sustainable recovery process. This study examines the post-disaster rebuilding process in spatial terms for Bolivar Peninsula in the aftermath of Hurricane Ike. It further investigates the nexus between connectivity among open space networks to various levels of surge damage among Bolivar spontaneous settlements. The study uses syntactical methods to measure axial connectivity of the Bolivar Peninsula access grid and one-way Analysis of Variance to interpret the way connectivity varies along the no damage to destroyed damage scale. In addition, the permeability rubric analyzes the elevation characteristics of houses that demonstrated higher probabilities of survival through a logistic regression. The conclusions are based on two basic premises. Local knowledge demands an indefinite time to be adapted and mobilized because of the increasing intensity of natural disasters. In addition, the high frequency of disaster events significantly challenges the versatility of local coping and survival strategies. The results reveal that the connectivity of the access grid has an inversely proportional relationship with various damage levels, particularly for no damage and destroyed. Furthermore, out of a number of resiliency characteristics listed in the literature, only ground elevation and ground enclosure demonstrated probability significances for survival. Potentially, the results of this research could support three significant outcomes pertaining to sustainable disaster recovery: preserving place character, social justice among affected groups, and promoting rapid recovery.

This dissertation provides an examination of the recent phenomenon of entrepreneurship and innovation promotion in the Gulf Cooperation Council (GCC) countries. Through the use of the structured, focused comparison method, this research examines two cases, Oman and Qatar, to provide a deep analysis of the policy and practice of entrepreneurship promotion in the region. Despite a claim of responding to regional challenges of economic diversification and the weak participation of nationals in the private sector, entrepreneurship as a key component of each country???s quest for a knowledge economy seems paradoxical in its ostensible inconsistency with the Gulf rentier state status quo. Path dependencies from oil-led development and the concomitant labour market bifurcation have perpetuated incentive structures which obstruct innovation and entrepreneurialism. Responding to this puzzle, this research answers two questions. The first is concerned with the character and motivation of these strategies in the Gulf, and what that reveals about the evolution of policy making practices. The second assesses the role of the millennial generation and regional transformation. Through interrogating the entrepreneurship policy experience in the case studies, this research extends beyond the often perfunctory assumptions of rentier state literature to investigate the unfolding of development policies in the current milieu. This research finds that entrepreneurship promotion risks only becoming a new way of recasting rentier tools: rentierism 2.0. The study argues that governance in the Gulf is best understood as a contestation between reforms and rentier patterns. Being cognizant of this tension provides a venue for understanding how some policies contravene classic rentier expectations while others appear hypocritical as the implementation of policy announcements become obstructed by structural contradictions. This dissertation makes an empirical contribution on a prominent policy shift in the Gulf that has been largely ignored in social sciences. As well, it provides a theoretical contribution by integrating literature on development and innovation which is generally disconnected from scholarly work on Gulf political economy to deepen understandings of development and transition in the region. Overall, this project provides a window into transition and transformation, demonstrating the way rentier patterns and a combination of novel pressures interact and affect the practices of development policy making and the Gulf ruling bargain.

To monitor and assess direct anthropogenic impacts on an aquatic system requires knowledge of its natural variation. The goal of this study explored natural variation in the lake fish communities of the northern Bruce Peninsula, which may act as a reference condition for other studies. The results of this study indicated there has been a shift towards more small-bodied, native species present in the fish communities, potentially a result of beaver activity in the area. A second goal was to calculate gear sampling efficiencies to enable the design of efficient monitoring protocols for fish communities in small, shallow lakes. It was concluded that a wide variety of gears are required to assess the fish species composition in a lake. Fine-mesh hoops were the most effective gear; however, saturation was never obtained for boat electrofishing; therefore, additional research is required to determine effectiveness relative to the fine-mesh hoop net.
