Used in conjunction with traditional logging measurements, it is now possible to determine residual oil saturation in carbonate reservoirs, hydrocarbon volume in low-resistivity or low-contrast shaly and laminated sand formations, and hydrocarbon volume and mobility in heavy oil reservoirs.
The presence of oil in the three wells, in the shaly sandstones of the C-7 interval, is evidence that the petroleum system reached the area where these wells are located, and furthermore, may indicate that the boundary of the prospect may be located to the west, south and northeast, and possibly close to the location of the three wells.
The assumptions are as follows, firstly that the laminated sands which have sands and clays conduct independently, and secondly that clean shaly sands occurrence is present.
