Paper Number: PETSOC-99-32
... single water-oil contact. I have observed some instances where a single closed naturally fractured reservoir has two (and even three) different well-defined water oil contacts. This paper gives some ideas to how this can happen. The principles do apply to the case of multiple gas-oil contacts in a...
