CORE ORIENTATION USING OPTICAL CORE SCANNING AND ACOUSTIC MICRO IMAGING DATA
Abstract
Core analysis is obligatory when developing mineral deposits or estimating reserves. Coring is always accompanied by taking photographs of the samples. Today, these photographs can also be used for additional research. For example, it is possible to extract information about the optical porosity from photogrammetric data, carry out an automated lithological classification or determine other physical and chemical characteristics of rocks within the sampling interval. Photogrammetric imaging result is a digitally unwrapped surface of the sample. Surface geometry (relief pattern) is then precisely correlated with the spectral reflectivity of the sample. The most evident problem in this case is the absence of data on core orientation. This problem can be solved by correlating photogrammetric data with acoustic borehole imaging data with known spatial orientation parameters (inclinometer always comprises part of the micro imager). This paper presents the technological process of obtaining images of core surface using an automated optical scanning complex. The images are oriented basing on the acoustic micro imaging data. The complex?s potentialities are also analyzed in terms of obtaining information on fracturing, i.e. azimuths and angles, fracture opening, fracturing density, mineral filling etc.
