STATISTICAL DISTRIBUTIONS AND CORRELATIONS OF
PETROPHYSICAL PARAMETERS IN THE ARAB-D RESERVOIR, ABQAIQ OILFIELD, EASTERN SAUDI ARABIA
A. Sahin* and S. Saner*
The Upper Jurassic Arab-D is a complex carbonate reservoir present in the Eastern
Province of Saudi Arabia. It has been subdivided into five zones on the basis of porosity.
A statistical analysis of the extensive dataset from the three productive zones in the
reservoir unit (Zones 1, 2 and 3) has shown that patterns of well-log porosity and core
porosity distributions are strikingly similar in each zone, but that the means are not.
Consistently higher mean values observed in core distributions can be explained by a
possible bias in core selection and/or differences in the measurement conditions. The
results also show that each zone has a distinctive pattern of porosity distribution,
reflecting its general lithological character.
