EXPERIMENTAL INVESTIGATION OF MUD-FILTRATE INVASION USING RAPID MICRO-CT IMAGING
SPEAKER: Colin Schroeder, The University of Texas at Austin
Speaker Bio: Colin Schroeder is a Ph.D. candidate in the Jackson School of Geosciences at The University of Texas at Austin. He received a Master of Science degree in Petroleum Engineering from The University of Texas at Austin in 2017 and three Bachelor of Science degrees – Chemical Engineering, Economics, and International Studies – from Penn State University in 2012. Colin previously worked as a Facilities Engineer for Williams and completed summer internships with Shell, Chevron, and Chesapeake Energy. He is a 2019-2020 SPWLA Distinguished Speaker and served as President of the Student Chapter of SPWLA at The University of Texas at Austin in 2017-2018. Colin is a member of the 2020 Texas 4000 for Cancer team. During summer 2020, he and his Texas 4000 for Cancer teammates will embark on the longest annual charity bike ride in the world, a 70-day, 4,000+ mile cycling journey from Austin, Texas, to Anchorage, Alaska, in hopes of inspiring communities across North America to join them in the fight against cancer.

measurements are subject to uncertainty resulting from the effects of
mud-filtrate invasion. Accurate interpretation of these measurements relies on properly
understanding and correcting for mud-filtrate invasion effects. Although
attempts to experimentally investigate mud-filtrate invasion and mudcake deposition
have been numerous, the majority of published laboratory data are from
experiments performed using linear, rather than radial geometry, homogeneous
rock properties, and water-base, rather than oil- or synthetic oil-base
paper introduces and applies a new experimental method developed to more
accurately represent conditions in the borehole and near-wellbore region during,
and shortly after, the drilling process, when the majority of wellbore
measurements are acquired. Rather than using a linear flow apparatus, these
experiments are performed using cylindrical rock cores with a hole
axially through the center. Radial mud-filtrate invasion is induced by
injecting pressurized drilling mud into the hole at the center of the core
while the outside of the core is maintained at a lower pressure. During the experiments,
the core is rapidly and repeatedly scanned using high-resolution X-ray
micro-computed tomography (micro-CT), allowing for the spatial distribution of
mud-filtrate and mudcake thickness to be visualized and quantified as a
function of time.
using these experiments we are able to accurately evaluate the influence of
various rock properties, such as the presence of heterogeneity, and fluid
properties, including water- versus oil-base mud, on mud-filtrate invasion and
