In the epic search for a Northwest Passage, the narratives of explorers often described the Arctic landscape as picturesque or sublime, depending on the place, the circumstances, and the seasons. Ships that carried those intrepid explorers through this new world had ominous names such as the Terror and Erebus, that dark place between Earth and Hell. As

Measurements Of Drilling Hazards Before Drilling Measurement Of Drilling Hazards Before Drilling
Offshore Technology Conference, 1979ABSTRACT Most instrumentation presently used to define shallow drilling hazards has been unable, for numerous reasons, to provide the driller with much needed quantitative engineering measurements. In response to this obvious need, state-of-the-art hardware, digital data processing and geophysical interpretative ...

To Drill Or Not To Drill: A Synthesis of Expert Judgments
2001Petroleum exploration is a costly venture which always involves a great deal of uncertainties and unknown factors. A decision to drill could result in a giant discovery, a modest discovery, or a dry hole. The factors influencing drilling decisions could be of geologic, economic and personal nature. When making a decision based on geologic factors alone,
