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 ... -
Experimental investigation of fracture width limitations of granular lost circulation treatments
(Journal article; Peer reviewed, 2016-01)Drilling fluid losses into fractured shales is a major challenge. Lost circulation treatments are widely applied to mitigate the losses; however, the effectiveness of these treatments is affected by different physical ... -
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 ... -
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 ... -
Rate of penetration optimization using moving horizon estimation
(Journal article; Peer reviewed, 2016)Increase of drilling safety and reduction of drilling operation costs, especially improvement of drilling efficiency, are two important considerations in the oil and gas industry. The rate of penetration (ROP, alternatively ... -
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 ...
