Subsurface characterization of structural traps in the Outer Nunchia Foothills, Colombia

Master's thesis in Petroleum geosciences engineeringThe integration and interpretation of 2D and 3D seismic data, well information, geological maps and public information was used to identify the structural configuration of the outer Nunchia Foothills, to define the structural style and to evaluate the hydrocarbon prospectivity in terms of the structural configuration. A stack of hinterland-dipping monocline to imbricate structures were recognized. Based on the lower detachment levels, the outer Nunchia foothills were divided into three sub-divisions. The basal structures, with detachment in Gacheta Formation and involves Cretaceous rocks to León Formation. The Intermediate structures, with detachment level in Lower to Middle Carbonera, which involves rocks of Carbonera and León Formations; and the upper to surface structures, where the lower detachment is located in the Upper Carbonera and involves the younger rocks. In the outer Nunchia foothills, the reservoir units are involved only in the basal structures, where the southern structure was tested by the Tangara-1 well. The area is therefore classified to be of low hydrocarbon potential in terms of structural traps

Consistency Testing for Data-Flow Circuits

One means of making VLSI design tractable is to proceed from a high-level specification of a circuit in terms of functionality, to the circuit level. A notable error which may occur in a topdown design starting with a data-flow graph representation of a circuit is a design inconsistency due to deadlock. This paper attempts to further develop the theoretical basis for algorithms which analyze the deadlock property of circuits on the basis of their data-flow graph representations. A systematic scheme to verify the absence of deadlock in data-flow graphs is also presented

Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels

The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements. In many industrial components, toughness and fatigue performance are also very relevant. In the present study, bainitic steels with varying content of boron were fabricated, with the aim of analyzing the fracture toughness and changes in the fatigue life. The results show that a relatively small change in the boron content can cause a notable variation in the fracture toughness of bainitic steels. The maximum value obtained in fracture toughness was for the steel with the highest boron content. It was observed that the amount of interlath martensite constituents decreases in steels with the addition of boron, leading to the promotion of the presence of void coalescence and a remarkable rise in the toughness of bainitic steels. An increase on the fatigue life of the bainitic steels with an increase in the boron content was also observed, through analysis by means of Paris’ law. A comprehensive micrographic study was carried out in order to examine the mechanics of fatigue crack growth in the bainitic steels, revealing small longitudinal cracks in bainitic steels that lack boron. These cracks tend to disappear in bainitic steels that contain boron. To elucidate this behavior, micrographs of the surfaces generated by the crack growth process were taken, showing that several nano-cracks appeared between the bainite laths. It is finally argued that this high-energy consumption process of nano-crack nucleation and growth is the reason for the improved toughness and fatigue life observed in bainitic steels.Peer ReviewedPostprint (author's final draft

Effect of Dry and Wet Storage on Post Harvest Life and Flower Quality in Cut Tulip cv. Cassini

Experiments were conducted during 2002-03 and 2003-04 to study the influence of storage methods and duration on post harvest quality of cut tulip cv. Cassini. Cut tulips cv. Cassini stored either dry or wet at 4°C for 0,2,4,6 and 8 days showed that days to flower opening was the lowest in those kept under wet storage for 6 and 8 days. Flower opening was better with 0.2 and 4 days of dry or wet storage whereas flowers stored dry for 8 days did not open at all. Flower size and vase life decreased with the increase in storage period. Larger flowers were obtained with dry and wet storage of 0 and 2 days whereas higher vase life was obtained with zero days of wet and dry storage and 4 and 6 days of wet storage
