INA d.d. has carried out systematic hydrocarbon exploration in Croatia since 1952. In the last 62 years it resulted in the discovery of 57 onshore oil and gas fields and 17 offshore gas fields, i.e. 1.4 billion boe of hydrocarbon reserves of which 1.2 billion boe was recovered. The Pannonian Basin can be considered a relatively well explored area where remaining potential should be looked for i...

For Dave Wood Prior to his untimely death, my friend Dave Wood gave me wise counsel about how best to organize a paper describing uses of statistics in oil and gas exploration. A preliminary reconnaissance of the literature alerted me to the enormous range of topics that might be covered. Geology, geophysics with particular attention to seismology, geochemistry, petroleum engineering and petrol...

Introduction. Typically, investment in petroleum exploration and development yields a joint product: reserves of oil and natural gas. The reserve additions are separable, but the expenditures generating reserve additions cannot be neatly partitioned between the two hydrocarbon sources.

Many processes within the oil and gas domain deal with ‘big data’–large sets of multidimensional data. Effectively analyzing these data sets is crucial to understanding the structure and the be­ haviour of oil and gas fields, and to the optimization of hydrocarbons production. However, experts face many challenges while attempting to analyze these data sets due to their high dimensionality, the...

With the oil and gas industry growing rapidly, increasing the yield and profit require advances in technology for cost-effective production in key areas of reservoir exploration and in oil-well production-management. In this paper we review our group's research into fiber Bragg gratings (FBGs) and their applications in the oil industry, especially in the well-logging field. FBG sensors used for...

The increased demand for oil and gas places a burden on lands set aside for natural resource conservation. Oil and gas development alters the environment locally and on a much broader spatial scale depending on the intensity and extent of mineral resource extraction. The current increase in oil and gas exploration and production in the United States prompted an update of the number of pipelines...

It is notable that over the past decade, proven reserves of natural gas have dramatically increased as higher prices and advances in technology have turned previously unrecoverable resources into major sources of domestic production. Moreover, the decline in crude oil reserves has significantly slowed over the past decade. Therefore, there would be an end to the conventional hydrocarbon resourc...
