Criteria for Identification of Low Resistivity Layers in MQ Oilfield in Subei Basin
-
Abstract
The low resisitivity layers in MQ oilfield are the result of the thin mudstone layers interbeded between reservoirs. These interlayers lower the resistivity of oil layers, thus the identification of oil layer, water layers and dry layers is difficult on conventional logs. New integrated interpretation techniques with multi - equation and multi -parameter are used to accurately discriminate oil and water layers. This paper presents several effective methods for identification of low resistivity layers and the criteria for i-dentification of oil layer, water layer and dry layers.
