“…Subsequently, several observations of kilometer-scale sand injections have been made particularly in relation to Paleogene oil and gas fields of the North Sea (MacLeod et al, 1999;Duranti et al, 2002;Purvis et al, 2002;Hurst et al, 2003;Huuse et al, 2005). In seismic data the intrusions are recognized as high-amplitude reflections cross-cutting the surrounding strata giving rise to a variety of geometries including dykes, sills, conical, saucer-shaped and wing-like intrusions (Fig.…”

The study fo cuses on Up per Cre ta ceous-Paleocene de pos its from the Beskid Śląski moun tain range in south ern Po land con sti tut ing the Istebna Beds. The Istebna Beds, also re ferred to as the Istebna For ma tion, are part of the Silesian tec tonic unit, which forms the Outer Carpathian fold-and-thrust belt (part of the Al pine-Carpathian sys tem). The re sults of qual i ta tive and quan ti ta tive lithological-sedimentological stud ies were the ba sis for the in ter pre ta tion of lithofacies types, sed i men tary pro cesses and palaeoenvironment as well as for the re con struc tion of the ar chi tec ture of the depositional sys tem. The anal ysis con ducted on the ba sis of field de scrip tion of the de pos its shows the prev a lence (nearly 70%) of siliciclastic strata rep resent ing a sand stone-con glom er ate as so ci a tion (S-C), which is the main sub ject of this work. The S-C lithofacies: sand stones, grav elly sand stones, sandy con glom er ates and con glom er ates con sti tute the de pos its formed mostly by mass grav ity-flows such as sandy-to-grav elly de bris flows. The dis tri bu tion of the coarse-clastic ma te rial in di cates a sed i ment supply from south erly di rec tions and im plies the pres ence of an ac tive source area in the rear part of the Silesian Ba sin.

“…Fluid simulation in petroleum reservoirs is developed to optimize well productivity, to match production data, to update geological models, to preview and update the distribution of flow units, to evaluate infill opportunities (Purvis et al 2002), and to compare results from analog models. The flow and mass transfers in underground reservoirs are complex, but better modeled with numerical simulations by using entropy (Delay & Lamotte 2000).…”

This paper has reported the use of geological and geophysical data into a 3D flow simulation model (gas). To adopt freeware software in flow simulation, we produced a program called GeoGrid3D. Our program is available with fault insertion features into ASCII 3D models. Also, it has other codification functions that change data for boast recognition (boast is the flow simulation freeware issued by the United States Department of Energy). We have developed the 3D reservoir grid and the structural framework model with data from outcrops of Permian sedimentary rocks and shallow seismic reflection. Analysis of geological facies in outcrops and their correlation with the stratigraphy are the methods used in 3D grid geological modeling and petrophysical properties. To demonstrate GeoGrid3D functions, we elaborated a main petrophysical model with supplementary three hypothetical tectonic faults playing. The gas saturation, after flow simulation, confirms that changing faults permeability inside the reservoir will change gas production in this model.
