Abstract

Due to a limited number and poor quality of the available core samples, sandstone analogues are required for a research project on sand production in Kazakhstan. A consistent sample preparation method is essential to achieve repeatable test results in terms of the deformational characteristics and the failure strength of the rock. This paper presents results of the work conducted to produce synthetic sandstone samples by firing clay and sand mixture. The samples replicate the reservoir sandstones in terms of the particle-size distribution, cement content, mineralogy and porosity. The reservoir sand was used as a material for the sandstone samples. The samples with 20% and 30% clay content were prepared. Effect of temperature and firing duration was studied by firing the samples at 200°C for 5 hours, 200°C for 8 hours and 500°C for 5 hours. Scanning Electron Microscopy analysis was conducted on the samples to study the chemical transformation during firing and its effect on clay cementation. Triaxial test behavior of the reservoir sand and sandstone samples was investigated.
