Abstract
Summary
The elastic properties of North Sea chalk formations are controlled by porosity, matrix properties (though mostly pure calcite), rock texture, pore fluids and pressure, where porosity is expected to be the dominant factor. Lithology and fluid characterization is more challenging as their elastic signature may be diffuse and ambiguous. In this paper we present a first application of the IRPM method for predicting the PLF properties of a North Sea chalk reservoir, and discuss the requirement to data quality needed to make such predictions.
