@article { , title = {Sand failure: effect of biocide on the geomechanical properties of outcrop carbonate rock under static condition.}, abstract = {The effects of chemical interaction of a biocide with formation rocks on the rock geomechanical properties are examined. A combination of analytical tests (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 in the effluent showed an increase in D50 with poor sorting for the chemically treated outcrop 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 in compressive strength of the carbonate following treatment with the biocide. The results give more insight into the limitations of existing sand production prediction models with respect to the effect of oilfield chemicals on the strength of the reservoir rocks.}, doi = {10.1007/s12517-020-06176-y}, eissn = {1866-7538}, issn = {1866-7511}, issue = {23}, journal = {Arabian journal of geosciences}, note = {INFO COMPLETE (Now Gold via offset deal 27/10/2020 LM -- Info of acceptance from contact 26/10/2020 LM) PERMISSION GRANTED (version = AAM/VOR; embargo = 12 months/none; licence = pub's own/BY; SHERPA = http://v2.sherpa.ac.uk/id/publication/7844 0 DOCUMENT READY (VOR downloaded 22/11/2020 LM ) ADDITIONAL INFO - Contact: Elizabeth Wuyep; Gbenga Oluyemi; Kyari Yates}, publicationstatus = {Published}, publisher = {Springer}, url = {https://rgu-repository.worktribe.com/output/978643}, volume = {13}, keyword = {Chemical interaction, Glutaraldehyde, Dolomite, Uniaxial compressive strength, Reservoir rock}, year = {2020}, author = {Wuyep, Elizabeth and Oluyemi, Gbenga and Yates, Kyari and Akisanya, Alfred R.} }
