Input data fileRunning SimulationFAQReferencesSummaryInfoSection-header KeywordsKeywords in SectionsGeneral InformationsUseful InformationsRunning SimulationSample SimulationVisualization SoftwareGeneral InformationsECLIPSE 100 is a fully-implicit, three phase, three dimensional, general purpose black oil simulator with gas condensate option.Program is written in FORTRAN77 and operate on any computer with an ANSI-standard FORTRAN77 compiler and with sufficient memory.ECLIPSE 100 can be used to simulate 1, 2 or 3 phase systems. Two phase options (oil/water, oil/gas, gas/water) are solved as two component systems saving both computer storage and computer time. In addition to gas dissolving in oil (variable bubble point pressure or gas/oil ratio), ECLIPSE 100 may also be used to model oil vaporizing in gas (variable dew point pressure or oil/gas ratio).Both corner-point and conventional block-center geometry options are available in ECLIPSE. Radial and Cartesian block-center options are available in 1, 2 or 3 dimensions. A 3D radial option completes the circle allowing flow to take place across the 0/360 degree interface.What is it ECLIPSE 100?FAQReferencesSummaryInfoSection-header KeywordsKeywords in SectionsGeneral InformationsUseful InformationsRunning SimulationSample SimulationVisualization SoftwareGeneral InformationsHow to start?To run simulation you need an input file with all data concerning reservoir and process of its exploitation.Input data for ECLIPSE is prepared in free format using a keyword system. Any standard editor may be used to prepare the input file. Alternatively ECLIPSE Office may be used to prepare data interactively through panels, and submit runs.The name of input file has to be in the following format: FILENAME.DATAFAQReferencesSummaryInfoSection-header KeywordsKeywords in SectionsGeneral InformationsUseful InformationsRunning SimulationSample SimulationVisualization SoftwareGeneral InformationsAn ECLIPSE data input file is split into sections, each of which is introduced by a section-header keyword. A list of all section-header keywords is given in following, together with a brief description of the contents of each section and examples of keywords using in file code.The keywords in the input data file (including section-header keywords) are each of up to 8 characters in length and must start in column 1. All characters up to column 8 are significant. Any characters on the same line as a keyword from column 9 onwards will be treated as a comment.Note that all keywords in input file have to be in proper orderRead more about basic principles of computer modeling in Reservoir Simulation e-learning modules or on website: http:/iptibm3.ipt.ntnu.no/kleppe/Use frame command under UNIX system to read Reference ManualInput data fileFAQReferencesSummaryInfoSection-header KeywordsKeywords in SectionsGeneral InformationsUseful InformationsRunning SimulationSample SimulationVisualization SoftwareSection-header keywordsThe list of section-header keywords in proper order:RUNSPECGRIDPROPSREGIONSSOLUTIONSUMMARYSCHEDULEThe sections must be specified in the shown order.
