Hydraulic fracturing for gas production is now ubiquitous in shale plays, but relatively little known about shale-hydraulic fluid (HFF) reactions within the reservoir. To investigate during shut-in period of hydraulic fracturing, experiments were conducted flowing different HFFs through fractured Marcellus cores at reservoir temperature and pressure (66 °C, 20 MPa) one week. Results indicate with hydrochloric acid cause substantial dissolution carbonate minerals, as expected, increasing...
Organobromine (Br org ) compounds, commonly recognized as persistent, toxic anthropogenic pollutants, are also produced naturally in terrestrial and marine systems. Several enzymatic abiotic bromination mechanisms have been identified, well an array of natural Br molecules associated with various organisms. The fate the carbon‐bromine functionality environment, however, remains largely unexplored. Oceanographic studies noted association between bromine (Br) organic carbon (C sediments. Even...
Carbon dioxide sequestration in deep saline and depleted oil geologic formations is feasible promising; however, possible CO2 or CO2-saturated brine leakage to overlying aquifers may pose environmental health impacts. The purpose of this study was experimentally define a range concentrations that can be used as the trace element source term for reservoirs pathways risk simulations. Storage terms metals are needed evaluate impact brines leaking into drinking water aquifers. metal release...
Nitroaromatic pesticides (NAPs) are hydrophobic contaminants that can accumulate in sediments by the deposition of suspended solids from surface waters. Fe(II) and dissolved organic matter (DOM), present suboxic anoxic zones freshwater sediments, transform NAPs natural systems. We studied reduction pentachloronitrobenzene (PCNB) to pentachloroaniline (PCA) controlled studies using water DOM isolates Pony Lake, Antarctica, Suwannee River, GA, unfiltered 0.45 μm filtered solutions. observed...
Fractured rocks are essential for flow, solute transport and energy production in geosystems. Existing studies on mineral reactions fractured mostly consider single systems where occur at the fracture wall without changing rock matrix properties. This work presents multicomponent reactive numerical experiments a from Brady's field, geothermal reservoir depth of 1,396 m Hot Springs Mountains, Nevada. Initial porosity, permeability, composition (quartz, clay, calcite), geometry based...
Barite scaling during the low-flow, shut-in period in hydraulic fracturing operations shale gas production has been intensively studied, but stimulation periods when large volumes of water are injected at high flow rates mostly overlooked. Due to variable nature injections, kinetics precipitation and morphology precipitated scale minerals vary due different solute concentrations influences on fluid–rock interactions. stages was studied using flow-through experiments with fractured Marcellus...
A vital aspect to public and regulatory acceptance of carbon sequestration is assurance that groundwater resources will be protected. Theoretical laboratory studies can, some extent, used predict the consequences leakage. However, direct observations CO2 flowing through shallow drinking water aquifers are invaluable for informing credible risk assessments. To this end, we have sampled wells in a natural analog site New Mexico, USA, where from sources upwelling depth. We collected major ion,...
Natural gas extraction from the Appalachian Basin has significantly increased in past decade. The push to properly dispose, reuse, or recycle large amounts of produced fluids associated with hydraulic fracturing operations and design better necessitated a understanding subsurface chemical reactions taking place during hydrocarbon extraction. Using autoclave reactors, this study mimics conditions deep shale reservoirs observe evolution shut-in phase (HF), period when (HFFs) remain confined...
