  • Mineral Reactions in Shale Gas Reservoirs: Barite Scale

    8/2/2017· HFFs with reused produced water composition cause precipitation of secondary minerals, particularly barite, decreasing effective fracture volume by 1-3%. Barite precipitation occurs despite the presence of antiscalants in experiments with and without shale contact and is driven in part by addition of dissolved sulfate from the decomposition of persulfate breakers in HFF at reservoir conditions.

    Although barite can also form after gypsum and/or anhydrite [ 4, 8 ], barite deposits associated to sulfate evaporite sequences are volumetrically much less relevant than their celestite counterparts [ 5, 6 ]. ICDP reactions play a major role in the re-equilibration between mineral phases and aqueous fluids in

    An example of a series of mineral reactions is illustrated as follows. Orthoclase feldspar (KAlSi 3 O 8) is a mineral commonly found in granite, a plutonic igneous rock. When exposed to weathering, it reacts to form kaolinite (Al 2 Si 2 O 5 (OH) 4, a sedimentary mineral, and silicic acid): 2 KAlSi 3 O 8 + 5 H 2 O + 2 H + → Al 2 Si 2 O 5 (OH) 4 + 4 H 2 SiO 3 + 2 K +
