This technology includes spatialattribute modeling and the visualization of hydrocarbon reservoirs to improvethe understanding of the geological structure including internal features andthe distribution of formation properties.This paper discusses experiences gained in building a geological model forthe LL-03 reservoir (in this reservoir there is a horizontal well drillingstrategy) and the subsequent manipulation and transfering of this data into a3D reservoir simulator for initialization purposes.The paper covers the modeling of fault planes in complex reservoirs, thehandling of both vertical and sloping fault surface and the distribution ofpetrophysical properties (porosity, permeability and water saturation) of thegeological model to be used in the reservoir simulation.The technique presented here differs considerably from the traditionalmethod for fault interpretation. This new method consists in interpreting theplane that describes the fault in the space, using several techniques thatallow defining the structural framework. Advantages for both, geocientists andreservoir engineers in displaying and reviewing the 3D image of the faultplanes and the reservoir at an early stage in the project are discussed.The paper concludes with suggestion for developments of the workflow tocreate the most realistic fault plane according to the structural framework tofurther enhance the effectiveness of the present 3D modeling method.IntroductionThe LL-03 reservoir is located in the Lake Maracaibo (Bolivar Coastal Field)and represents one of the biggest and oldest reservoirs of its northeasternregion. It occupies a lacustrine area of approximately 300 Km2, which includesLa Rosa, Punta Benitez, T a Juana and part of Lagunillas fields (figure1). It was discovered in 1925 by the exploratory well R-2, however thefirst production was reported in 1928. This production was from oil sands of LaRosa and Lagunillas Formations of Miocene age.The LL-03 reservoir has more than two thousand wells that penetrated itsvertical section, of which 1051 wells have been completed and contribute with30% of the total production of the La Rosa Medium segregation of the MaracaiboDistrict. The production average in the year 2000 was 30 MBOPD, 1673 CF/NB and43% of water cut and sediments with an injection rate of 76.3 MBWPD.The reservoir OOIP has been estimated in 6,9 MMbls. The primary and totalrecovery factors are 23.0 % and 24.5% respectively, with a remaining totalreserve of 124,885 MMbls.The seismic survey COL-95B-3D was concluded during the second semester of1996 (figure 2), which allowed for the execution of several detailedstudies to define the structural and stratigraphycal aspects of severalreservoirs of the area.At the moment, a 3D static model is under construction, which will be themain input to a process of numeric simulation and evaluation of future plansfor secondary recovery.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
