Abstract: Gas bubble migration can be managed in liquids. In one example, a system can execute wellbore-simulation software to simulate changes in gas dissolution in a liquid over time. This may involve dividing the wellbore into segments spanning from the well surface to the downhole location, each segment spanning a respective depth increment between the well surface and the downhole location. Next, for each time, the system can determine a respective multiphase-flow regime associated with each segment of the plurality of segments based on a simulated pressure level, a simulated temperature, a simulated pipe eccentricity, and a simulated fluid velocity at the segment. The system can also determine how much of the gas is dissolved in the liquid at each segment based on the respective multiphase-flow regime at the segment. The system can display a graphical user interface representing the gas dissolution in the liquid over time.

Abstract: Determining characteristics of a formation. At least some of the illustrative embodiments are methods including determining at least one characteristics of a shale formation. The determining may include: collecting optically interacted electromagnetic radiation from a portion of the shale formation; directing a first portion of the optically interacted electromagnetic radiation from the formation to a first multivariate optical element (MOE), the first MOE creates first modified electromagnetic radiation; applying the first modified electromagnetic radiation to a first detector, the first detector creates a first signal; and determining a first characteristic of the shale formation from the first signal.
