Treść
Recent discoveries of potential shale gas resources in Poland require profound understanding of their stratigraphy mainly in order to identify the best strata for horizontal drilling and hydraulic fracture treatment. An extensive conductive hydraulic fracture is essential to impose a pressure drop in the formation and produce hydrocarbons at the economical rate. Diversified mechanical properties of rocks can have significant impact on hydraulic fracture geometry. There are several laboratory methods used for evaluation of mechanical properties which are based mainly on acoustic wave techniques each having its advantages and disadvantages. However, in order to apply laboratory velocity data to log interpretation, it is necessary to know quantitatively the values of the velocities due to different frequencies employed during acoustic well logging (several hundred hertz to about 100 kHz) and laboratory measurements (0.1 to several MHz). This paper presents a set of shale sample data from different formations, which have been extensively recognized; they represent a wide range of petrophysical and mechanical properties. Acoustic wave velocity distribution vs. wave frequency ranging from kHz to MHz was analyzed. Diagenesis level, porosity and mineral composition, were also compared. The influence of each parameter on dispersion function was described and presented in a context of Polish shale rock formations. Mechanical properties of shale rocks have been determined using acoustic velocity measurements on cuttings, which are especially useful in intervals where the well logs and cores are not available, and there is no correlation to well logs. Dispersion of velocity vs. mineral composition was determined by XRD and FTIR techniques. The FTIR technique is complementary to X-ray diffraction measurements allowing to determine both crystalline and amorphous part of the examinated rock matrices, giving complete knowledge about its structural and chemical composition.
