The present work uses a micromechanical force apparatus to directly measure cyclopentane clathrate hydrate cohesive and hydrate-steel adhesive force, as function of contact time, temperature. We interparticle model, which includes capillary sintering contributions is based on fundamental theories. In this process, we estimate the tensile strength be approximately 0.91 MPa. This model also predicts effect temperature particle cohesion force. Finally, first direct measurements in gas phase 9.1...
During the Deepwater Horizon incident, crude oil flowed into Gulf of Mexico from 1522 m underwater. In an effort to prevent rising surface, synthetic dispersants were applied at wellhead. However, uncertainties in formation droplets and difficulties measuring their size water column, complicated further assessment potential effect dispersant on subsea-to-surface partition. We adapted a coupled hydrodynamic stochastic buoyant particle-tracking model transport fate hydrocarbon fractions...
Following the Deepwater Horizon blowout, major concerns were raised about probability that Loop Current would entrain oil at surface of Gulf Mexico toward South Florida. However, such a scenario did not materialize. Results from modeling approach suggest prevailing winds, through drift they induced ocean surface, played role in pushing coasts along northern Gulf, and, synergy with evolution, prevented reaching Florida Straits. This implies both oceanic currents and wind-induced must be taken...
A 130 ft single-pass, gas-dominant flowloop has been constructed to study hydrate formation in an annular flow regime by exposing warm process fluids a cold pipe wall. Hydrate was formed six experiments from natural gas mixture, with 6–18 °F subcooling equilibrium. At lower values stenosis-type film growth model without adjustable parameters used estimate the resulting pressure drop and yielded average deviation of 15.8 psi experimental value. The accuracy this decreases appreciably...
There are substantial economic and operational incentives to reduce the volumes of thermodynamic inhibitors (THIs) injected in deepwater oil gas pipelines a minimum threshold necessary achieve flowable hydrate slurry prevent deposition; however, there is uncertainty about whether this underinhibited condition may worsen transportability increase plugging potential. In study, formation rate hydrodynamic pressure drop were measured over range temperatures subcoolings using one-inch single-pass...
Gas hydrates represent an unconventional methane resource and a production/safety risk to traditional oil gas flowlines. In both systems, hydrate may share interfaces with aqueous hydrocarbon fluids. To accurately model macroscopic properties, such as relative permeability in systems or dispersion viscosity knowledge of interfacial properties is required. This work presents cohesive force results measured on micromechanical apparatus, complementary water-hydrocarbon tension data. By...
Recovering methane (CH<sub>4</sub>) <italic>via</italic> the injection of carbon dioxide (CO<sub>2</sub>) into a CH<sub>4</sub>-hydrate-bearing reservoir is highly attractive mechanism for meeting world's future energy demand, since it offers prospect carbon-neutral production.
Cyclopentane (CyC5) hydrate interparticle adhesion force measurements in the presence of small amounts crude oil (up to 8 wt % cyclopentane) were performed at 3.2 °C, under atmospheric pressure, using a micromechanical apparatus. The forces obtained for cyclopentane CyC5 bulk fluid lower than those measured pure fluid. hydrate-normalized adhesive be on order 0.5 mN/m samples containing approximately 5−8 Caratinga and Troika crude. Hydrate-normalized found increase when surface-active...
Adhesion forces between cyclopentane hydrate particles were measured at atmospheric pressure and 3.2 °C using an improved micromechanical force apparatus. Because of the complexity crude oil systems, a series model oils was prepared by adding surface-active components to 200 cP mineral as analogues systems. The addition 1 wt % sorbitan monooleate (Span80, commercial anti-agglomerant), polypropylene glycol (an amphiphilic polymer), 0.6 naphthenic acid mixture, separately, continuous phase,...
Recent studies have found discordant mechanosensitive outcomes when comparing 2D and 3D, highlighting the need for tools to study mechanotransduction in 3D across a wide spectrum of stiffness. A gelatin methacryloyl (GelMA) hydrogel with continuous stiffness gradient ranging from 5 38 kPa was developed recapitulate physiological conditions. Adipose-derived stem cells (ASCs) were encapsulated this hydrogel, their morphological characteristics expression both proteins (Lamin A, YAP, MRTFa)...
