... the actual rock characteristics. Core samples are typically analyzed to identify reservoir quality, storage and flow capacity, rock grain size and other mineralogical information. The robotic untethered sidewall coring tool (RUSCT) is an autonomous device that can extract a sample from the formation...

... envelope, resulted in severe blockages in the core sample. Manipulation of the temperatures and pressures at specific trajectories allowed for determination of CO 2 hydrates blockages. Reproduction of injectivity impairment under a variety conditions, saturations and flow rates demonstrated the ability...

... dissolution testing of dolomite core samples in the presence of 28 wt% hydrochloric acid (HCl), both with and without additives, were performed at ambient conditions. The weight loss was calculated, and the efficiency of the added chemicals was evaluated to select the formulation for evaluation at reservoir...

... properties. Therefore, core samples belonging to the same flow unit generally exhibit better porpoperm correlations than those from the entire well. Based on this principle, we first classify reservoir rocks into a number of facies and then define a poroperm relationship for each facies based on core...

Tri-axial compression test on those core samples has been conducted to ascertain mechanical properties of natural hydrate bearing sediments for the first time. The results from the tests show that with increase in pore saturation of gas hydrate...
