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...
Abstract Understanding mechanisms controlling fluid injection-triggered seismicity is key in defining strategies to ameliorate it. Recent triggered events (e.g. Pohang, Mw 5.5) have exceeded predictions of average energy release by a factor >1000x, necessitating robust methodologies both define critical antecedent conditions and thereby constrain anticipated event size. We maximum magnitudes resulting from triggering as function pre-existing stresses injection volume. Fluid experiments on...
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...
Abstract Proximity ligation assays (PLAs) use specific antibodies to detect endogenous protein‐protein interactions. PLAs are a highly useful biochemical technique that allow two proteins within proximity be visualized with fluorescent probes amplified by PCR. While this has gained prominence, the of PLA in mouse skeletal muscle (SkM) is novel. In article, we discuss how method can used SkM study interactions mitochondria‐endoplasmic reticulum contact sites (MERCs). © 2025 The Author(s)....
Abstract OPA1 is a dynamin‐related GTPase that modulates mitochondrial dynamics and cristae integrity. Humans carry eight different isoforms of mice five, all which are expressed as short‐ or long‐form isoforms. These contribute to OPA1's ability control energetics DNA maintenance. However, western blot isolation long short can be difficult. To address this issue, we developed an optimized protocol based on improving running time isolate five in mouse cells tissues. This applied study...
This paper describes a new modeling framework for microscopic to reservoir-scale simulations of hydraulic fracturing and production. The approach builds upon fusion two existing high-performance simulators behavior: the GEOS code hydromechanical evolution during stimulation TOUGH+ multi-phase flow are informed by experimental studies at laboratory scale incorporate important micro-scale mechanical processes chemical reactions occurring within fractures, shale matrix, fracture-fluid...
In order to reduce greenhouse gas emissions while recovering hydrocarbons from unconventional shale formations, processes that make use of carbon dioxide enhance oil recovery storing (CO2) should be considered. Here, we examine samples three basins across the United States (Utica and Marcellus Shales in Appalachian Basin, Barnett Shale Bend Arch-Ft. Worth Eagle Ford Western Gulf Basin) address following questions: (1) do changes reaction with CO2 fluids at micrometer nanometer scale alter...
Fracture injection/shut-in tests are commonly used to measure the state of stress in subsurface. Injection creates a hydraulic fracture (or some cases, opens preexisting fracture), and then pressure after shut-in is monitored identify closure. Different interpretation procedures have been proposed for estimating closure, sometimes yield significantly different results. In this study, direct, in-situ strain measurements observe reopening The were performed as part EGS Collab project,...
Abstract The National Energy Technology Laboratory (NETL) in conjunction with industry partners began a project to assess field-generated foamed cement at pressurized surface conditions. collected samples were compared previous as well equivalent generated current laboratory protocols following the recommended practices American Petroleum Institute's Recommended Practice (API RP) 10B-4; atmospherically generated. In-situ of successfully captured constant pressure (CP) cylinders under field...
Summary Computed-tomography (CT) scanning has become a mainstay among scientists (Wildenschild and Sheppard 2013) because it enables nondestructive observation of material processes formation in real time. Foamed cement is high-strength, low-density containing nitrogen gas, used to stabilize wellbore casings both onshore offshore. In-situ foamed subject pressure changes the slurry pumped downhole cures at depth. To correlate influence gas-void size curing evolution cement, two laboratory...
Barite scaling is a common problem in the shale gas industry. precipitation due to rock-fluid interactions has been studied intensively static and flow-through experiments, but impact of flow pathway geometry on barite remains question. The complex fracture passages can lead local concentrated geochemical interactions, resulting spatially variable distribution. In this study, designed patterns with channels holes were milled two Marcellus cores represent main pathways, where slow travels...
The U.S. Department of Energy’s National Energy Technology Laboratory (DOE-NETL) has been developing methods and tools (the online Carbon Dioxide Storage prospeCtive Resource Estimation Excel aNalysis (CO2-SCREEN) tool) to estimate carbon dioxide (CO2) storage potential in subsurface reservoirs. CO2 efficiency terms are input the tool calculate targeted In this effort, two were evaluated: volumetric displacement ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <msub> <mrow>...
Foamed cements are widely used for cementing oil or gas wells that require lightweight slurries, migration prevention, in high-stress environments. When this manufactured slurry solidifies the sub-surface environment distribution of voids can affect resultant strength, permeability, and stability wellbore casing. Researchers at National Energy Technology Laboratory have produced first high-resolution X-ray computed tomography (CT) three-dimensional images atmospheric field generated foamed...

Fluid flow in the subsurface is not well understood context of "impermeable" geologic media. This especially true formations that have undergone significant stress fluctuations due to injection or withdrawal fluids alters localized pressure regime. When regime altered, these formations, which are often already fractured, move via shear reduce imbalance state. While this process known happen, evolution fractures and their effects on fluid transport still relatively unknown. Numerous...
