Really logs provide understanding of the structures and you may criteria throughout the subsurface, aligned mainly within detection and you may analysis out-of possibly productive limits.
Commitment of saturation
Water saturation ‘s the tiny fraction of pore amount of new tank rock that’s filled Cairns legit hookup sites up with water. It’s fundamentally assumed, except if if not understood, that the pore regularity not filled with liquids is full of hydrocarbons. Determining liquid and you can hydrocarbon saturation is just one of the earliest objectives from well logging.
Clean formations
All-water saturation determinations regarding resistivity logs in clean (nonshaly) formations having homogeneous intergranular porosity are derived from Archie’s liquid saturation formula, or distinctions thereof. [1] [2] The fresh new equation try
To possess simplicity, the latest saturation exponent n can often be pulled because dos. Lab tests show this are a fair really worth to have average instances. Fortsett å lese F is oftentimes extracted from this new mentioned porosity of your own creation from matchmaking
