Title

Fluid pH and major and minor element data from shale-acidic fluid interaction laboratory experiments

Abstract

This dataset presents major (ICP-OES) and minor (ICP-MS) element data and fluid pH during interaction of simulated fracturing fluids with the Bowland-Hodder shale at a variety of conditions, i.e. fluid acidity (pH 1-5), temperature (25-70 C), and rock/fluid ratio (from 0.2:200 to 20:200), as well as two end member mineralogical compositions (from 618 m depth and 673 m depth). The data was collected under the SECURe (Subsurface Evaluation of CCS and Unconventional Risks funded under the European Union’s Horizon 2020 research and innovation programme under grant agreement number 764531. Data supplied by permission of University of Nottingham and British Geological Survey.

Lineage

The solution in our experiments was prepared by Milli-Q water, and the fluid pH was adapted by adding small amounts of concentrated or diluted HCl. The experiments testing the impact of fluid acidity and temperature were conducted at a constant solid to liquid ratio of 1:100 (2 g shale powder in 200 mL solution, whereas rock/fluid ratios systematically varied experiments were carried out to evaluate the impacts of changes in rock-fluid contact on elemental mobilisation at a constant fluid pH of 1.0 and ambient temperature of 60 °C. Each powdered sample was added to a 200 mL solution, where the suspension was continuously stirred using a Teflon-coated magnetic stirrer bar. Each experiment was run for a total of 100 hours, and aliquots (2 mL) were sampled at 0, 1, 3, 7, 23, 27, 31, 54, 77, 100 h and filtered through 0.22 µm polyethersulfone membranes for further analysis.
