Assessing the performance of fracturing fluids integrated with amino acids as kinetic hydrate inhibitors in exceptionally low temperature environments

The reason for the lack of permeability in gas hydrate bearing sediments is due to the assumption of hydrates in porous spaces of these sediments, inevitably blocking transfer channels inside them. The limited control over the sediments impacts the command on efficient depressurization, limits the capacity for reservoir modification (chemical injection), and impacts the potential of sediments to produce at higher rates. This study is an initiative to test the compatibility of conventional polymers and crosslinkers for exceptionally low temperature fracturing applications and investigate the compliance on integrating established gas hydrate inhibitors (amino acids) for improving the efficiency of operation. The electrostatic interaction, chemical bonding and hydrophilic side chains of amino acids are responsible for the hydrate inhibition characteristics. Amino acids also possess clay stabilizing properties. Some of the best performing amino acid based kinetic hydrate inhibitors (KHIs) such as Glycine and Valine were introduced with guar polymers and crosslinkers to evaluate their compatibility with each other as well as towards gas hydrate sediment temperatures. Fracturing fluid properties such as viscosity, viscoelasticity, stability, and natural disintegration process were evaluated. The study concludes that introduction of amino acids can improve the properties of fracturing fluid when added at optimum proportions. Inhibitor integrated crosslinked gels did not display any observable expeditive disintegration nor did they tend to
