The effects of chemical interaction of a biocide with formation rocks on the rock geomechanical properties are examined. A combination of analytical test (Scanning Electron Microscopy/Energy-Dispersive X-Ray Analysis, X-Ray Powder Diffraction and Particle Size Distribution) and uniaxial compressive test was used in this study. The particle size distribution showed an increase in D50 with poor sorting for the chemically treated carbonate core samples. The XRPD shows evidence of altered minerals in the chemically treated samples. It was observed that the interaction led to precipitation of new materials that clogged the pore space of the samples leading to up to 150% increase compressive strength of the carbonate following treatment with the biocide. The results give more insight into the limitations of the existing sand production prediction models with respect to the effect of oilfield chemicals on the strength of the reservoir rocks. Key words: Chemical interaction, glutaraldehyde, dolomite, uniaxial compressive strength, reservoir rock
