The ultimate goal for seismic depth imaging is to find new hydrocarbon prospects or improve existing ones. High quality seismic data and an accurate velocity model are the main drivers for good imaging. Prospects may be identified on seismic data in areas which can range from high to low signal. Roughly speaking, prospects generated for shallow targets will be on good signal data and prospects ...

To a decisionmaker facing a choice over a set of risky prospects the issue of ‘flexibility’, i.e., the ability to postpone other decisions until after the uncertainty is resolved, is a crucial one. Tisdell (1963) for example, has shown that the well known ‘preference’ of a risk neutral firm for random over constant prices (with the same mean) reduces to indifference when it is assumed that the ...

INTRODUCTION Advanced gastric cancer (AGC) is one of the most common forms of cancer and remains difficult to cure. There is currently no recommended therapy for second-line AGC in the UK despite the availability of various interventions. This paper aims to compare different interventions for treatment of second-line AGC using more complex methods to estimate relative efficacy, fitting various ...

I review the progress in fundamental spin physics over the past several years and the prospects for the future. The progress is striking and the prospects are excellent.

Corruption has become an issue of major political and economic relevance in recent years. This has led to a resurgence of interest in analyzing the phenomenon and the diverse forms that it assumes in developing politics with an expectation that democratization and economic liberation offer potential routes to dealing with the problem. Anti-corruption strategies range from institutional reforms ...

To alleviate the severe rocky desertification and improve the ecological conditions in Southwest China, the national and local Chinese governments have implemented a series of Ecological Restoration Projects since the late 1990s. In this context, remote sensing can be a valuable tool for conservation management by monitoring vegetation dynamics, projecting the persistence of vegetation trends a...

in the present paper, challenges and prospects of the european railways, along with a proposal for a new strategy policy and specific measures are presented. the declining course of european railways concerning traffic and revenues is first analyzed. conditions to introduce intra - modal competition are surveyed, among them separation of infrastructure from operation as it has been applied in a...
