A device for simulating injections of liquid chemical/cementitious substances into soils, comprising a first observation chamber which delimits an injectable space adapted to accommodate a soil sample, a second observation chamber which delimits a perforation space adapted to accommodate at least one stretch of an injection device, with longitudinal extension along a longitudinal axis of the second observation chamber, wherein the first observation chamber and the second observation chamber are directly bordering to each other in an interface area, a retaining partition wall which can be inserted in the interface area so as to separate the injectable space from the perforation space and extracted so as to put the perforation space into communication with the injectable space, as well as first transparent portions formed in a first containment wall of the first observation chamber for viewing in real time a propagation of the chemical substance injected into the soil sample by means of the injection device. A method comprising a step of simulating by the device.

Systems and methods to evaluate a formation by analyzing drill cuttings involve a multi-frequency dielectric coaxial probe to obtain a reflected voltage from a medium under test based on a reference voltage over a frequency range. The medium under test includes the drill cuttings. The system includes a processor to compute an effective permittivity of the drill cuttings over the frequency range based on a reflection coefficient, which is a ratio of the reflected voltage to the reference voltage over the frequency range, and to determine one or more parameters from the effective permittivity. The one or more parameters are used to make decisions about subsequent drilling in the formation.
