In this work we present a novel level set technique for shape reconstruction in history matching for reservoirs with two or more kinds of rocks (the so-called lithofacies) using stochastic initializations. In the paper we discuss the use of sequential Gaussian simulation for the creation of geostatistical initial guesses which will then be applied to an earlier introduced level set based shape ...
ANDRILL completed its first season in 2006-07 drilling AND-1B through the McMurdo Ice Shelf (MIS) to a depth of 1,285m below the sea floor, a record for Antarctic margin drilling, with 99% recovery. The alternating glacial-interglacial sediment packages interbedded with volcanics provide a uniquely detailed record of Antarctic glacial and climatic change through the Neogene. This paper summariz...
this study aims to identify favorable oil–gas reservoir facies in the chishan group of the wubao fault zone (gaoyou sag, subei basin, china) using the methods of outcrops and cores observation, granularity analysis, scanning electron microscope, log data, etc. the results suggest that the chishan group in the studied area mainly develops desert sedimentary system, and contains five kinds of fac...
Lithofacies belonging to mud-flat and palustrine deposits (lake margin) in the Miocene of Madrid Basin (Spain) have been studied. Four lithofacies corresponding mud flat (1 3) (2 4) differentiated. Units 1 3 consist mainly mudstones carbonates (calcretes diolocretes). The clay fraction is dominated by trioctahedral smectite (up 79%) with illite kaolinite as minor components. d(060) spacing valu...
sediments of the nezam-abad area, south-east of bam have been studied for the first time. sedimentary facies are composed of thin-bedded clay, silt and fine grained sand interbedded with thin laminated limestone. chemical analysis of x-ray florescent indicates that more than 50% of sediments consist of silisium and aluminum oxide that can be used for reconstruction of environment. ninety eight ...
