-- -- HORIZONTAL WELL SIMULATION -- ************************** -- -- -- This data deck contains the information required to simulate a -- horizontal well producing from a thin oil rim and ignoring any -- friction pressure drop in the tubing, in three different ways. -- -- a) The data deck as set up will work with ECLIPSE 100. It uses fin -- cells around the wells but, of course, these have to extend -- throughout the model into regions where very little fluid movem -- is occurring, this is inefficient so; -- -- b) Makes use of Local Grid Coarsening (LGC) to aggregate cells at -- the periphery of the model into larger cells. This reduces the -- number of active cells that have to be solved, hence reducing -- running time. Also; -- -- c) Uses the opposite approach to ii) in that instead of refining a -- lot of cells and then coarsening them only a few are refined fr -- the start; in other words Local Grid Refinement (LGR) is applie -- Additionally the refined cells, where a lot is happening quickl -- can be solved for small time steps if necessary whilst the more -- static external cells (and a global cell at the well) are solve -- for larger steps. -- -- Note that the lines that pertain to cases b) and c) are currently -- commented --b and --c respectively and should replace the immediatel -- preceeding lines. -- -- -- The results for cases a) and b) are identical, whilst case c) gives -- slightly different results. -- RUNSPEC TITLE HORIZONTAL WELL MODEL DIMENS 20 9 9 / NONNC OIL WATER GAS DISGAS FIELD EQLDIMS 1 100 2 1 2 / EQLOPTS 'QUIESC' 'MOBILE' / TABDIMS 1 1 15 10 1 10 / WELLDIMS 1 10 1 1 / START 1 'JAN' 1990 / NSTACK 6 / UNIFOUT OPTIONS 16*0 1 / GRID NOECHO GRIDFILE 2 / DXV 20*100 / DYV 300 120 50 20 10 20 50 120 300 / DZ 180*50 180*50 180*30 180*15 180*10 180*15 180*30 180*50 180*50 / TOPS 180*7000 / --c --c Geometry definition for run making use of LGR refinement of --c cells surrounding the well --c --cDXV --c 4*500 --c/ --c --cDYV --c 300 120 150 120 300 --c/ --c --cDZ --c 20*50 20*50 20*100 --c 20*50 20*50 --c/ --c --cTOPS --c 20*7000 --c/ EQUALS 'PORO' 0.25 / 'PERMX' 100 / / COPY 'permx' 'permy' / 'permx' 'permz' / / MULTIPLY 'permz' 0.050 / / --b --b Data to coarsen those cells lying far from the well in the --b LGC case.
