Paper Number: SPE-188100-MS
... Abstract Since conventional history matching aimed at fractured horizontal wells in low permeability oil reservoirs is affected by a number of factors, such as permeability, fracture half-length, conductivity and so on, there often exists ambiguity in production matching. That is to say, when...
