Friction along the wellbore, through the perforations and the near-wellbore area of the fracture can hide from us what is truly happening with frac pressures downhole. As VP of Engineering, Leen Weijers, demonstrates here in a comparable situation while he inflates a bike tire, there is a simple solution to obtaining an accurate downhole –…
In this home educational video, VP of Engineering, Leen Weijers, inflates the tire of his wheel barrow to introduce concepts of net pressure and closure stress, and shows how fracture width and net pressure are related.
Hydraulic Fracturing has been around since 1947 – and a lot has changed since then. Dr. Ouigee (Leen Weijers) breaks down the evolution of shale wells, covering the transition of technology and progress made in horizontal fracturing in five easy pieces.
Natural gas occurs naturally in many more places than you think. Doc Ouigee explores wetlands and ponds near his CO home to find natural gas and explains hyped videos of water faucets catching fire are not associated with hydraulic fracturing activity.
Liberty’s Doc Ouigee demonstrates in his Home Frac Lab how we can measure Poisson’s Ratio and why it is important for frac design optimization.
Fracking is not just about breaking rocks. It is also about pushing rock out of the way! How easy that is depends, amongst others, on the stiffness of the rock – or what we call the Young’s Modulus.
Diversion strategies during the frac can help maximize the number of perforation clusters that effectively take frac fluid and proppant, thus ensuring that these clusters contribute to long-term production of a horizontal well. Top Nerd Leen Weijers discusses Liberty’s data-driven strategy and Lab Rat Joel Siegel reviews Liberty’s range of products that can help ensure…
How much effort does it take to fracture rocks? Learn about fracture growth through laminations in this Liberty Educational Video with Dr. Leen Weijers.
An update from Dr. Leen Weijers, Liberty’s VP of Engineering on continuing to minimize dollars per barrel of oil. This video expands on a presentation originally given at the SPE Hydraulic Fracturing Technology Conference in 2019.
Liberty’s Lab Manager, Joel Siegel, talks about the tools we use in our labs to to design fluid systems and ensure they behave as designed . It also provides an overview of rheology, viscosity, and viscometers as they relate to hydraulic fracturing and fluid dynamics.
