.../30484-MS Equilibrium Dune Level, EDL Experimental Results The equilibrium dune level (EDL) was measured for proppant transport experiments in addition to the propped surface area. EDL was measured using Klonk Image Measurement software by dividing the fracture slot height to the highest point...

... Experimental Setup Figure 4 shows the experimental setup used to conduct the proppant transport experiments. The setup consisted of a vertical model holder, progressive cavity pump, pressure transducer, and a camera. The progressive cavity pump was used to pump the proppant-laden fluid into the vertical...

... as the ratio of the mixture as curing the samples in water washes the cementation out and makes the samples weaker than expected. Authors recommend more TWC experiments to approve these equations and trends experimentally. These tests are better to be undertaken with two types of samples; a series...

In this experimental study, the impact of geomechanical changes on shales petrophysical properties is investigated using a laboratory set-up that was designed and assembled for fast and robust shale core plug porosity and permeability measurements under steady-state conditions. This laboratory set-up is capable...

... fractures, and CT scans taken after one day of the core flooding experiments prove that the fractures remain open even without proppant addition. Because air is an abundant, cheap, and easy to handle injection fluid, it is an attractive alternative to water for fracturing. Our experimental results support...

... Abstract Rheological experiments have been conducted with commercial and experimental friction reducers indicating certain profiles are advantageous for performance. In these profiles the factors of time and concentration are important in predicting the maximum performance window. These windows...
