Effect of Various Silica Nanofluids: Reduction of Fines Migrations and Surface Modification of Berea Sandstone
(Journal article; Peer reviewed, 2017-11)Abstract: This work is aimed at addressing surface modification of berea sandstone by silica nanofluids (NFs). Three types of nanofluids were used: silica/deionized water (DIW), silica in DIW with a stabilizer fluid ... -
Evaluation of the compositional changes during flooding of reactive fluids using scanning electron microscopy, nano-secondary ion mass spectrometry, x-ray diffraction, and whole-rock geochemistry
(Journal article; Peer reviewed, 2015-05)Outcrop chalk of late Campanian age (Gulpen Formation) from Liège (Belgium) was flooded with MgCl2 in a triaxial cell for 516 days under reservoir conditions to understand how the non-equilibrium nature of the fluids altered ... -
Gas Hydrate Growth Kinetics: A Parametric Study
(Journal article; Peer reviewed, 2016-12)Abstract: Gas hydrate growth kinetics was studied at a pressure of 90 bars to investigate the effect of temperature, initial water content, stirring rate, and reactor size in stirred semi-batch autoclave reactors. The ... -
Mechanical and physical behavior of high-porosity chalks exposed to chemical perturbation
(Journal article; Peer reviewed, 2015-09)Extensive study on the effect of dissolution–precipitation on mechanical behavior of various high-porosity outcrop chalks (Liége, Aalborg, Kansas, Stevns Klint, and Mons) flooded with simplified aqueous chemistry at 130 ... -
Numerical treatment of two-phase flow in capillary heterogeneous porous media by finite-volume approximations
(Journal article; Peer reviewed, 2012)This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, ... -
Porosity and permeability development in compacting chalks during flooding of nonequilibrium brines: Insights from long-term experiment
(Journal article; Peer reviewed, 2015-05)We report the complete chemical alteration of a Liège outcrop chalk core resulting from a 1072 flow-through experiment performed during mechanical compaction at 130°C. Chemical rock-fluid interactions alter the volumetric ... -
The Effect Of MoS2 -And Graphene Nanoparticles On The Properties & Performance Of Polymer /Salt Treated Bentonite
(Journal article; Peer reviewed, 2017)Among others, properly designed drilling fluid is a key for a success of drilling operation. The rheology, and lubricity of drilling fluids control the hydraulics, hole cleaning and the mechanical friction between string ...
