    Abstract: A logic used to auto-adjust plunger lift system parameters to optimize oil and gas well production with minimal human interaction is described. The auto-adjustments place and maintain the well in an optimized state wherein the well has either a Minimum-OFF time (e.g., length of time just long enough for the plunger to reach the bottom of the well), or Minimum-ON time (e.g., flowing just long enough for the plunger to reach the surface) cycle.

    Abstract: Implementations described and claimed herein provide systems and methods for isolation detection. In one implementation, a radial acoustic log is obtained. The radial acoustic log is captured using a radial sensor of an acoustic logging tool deployed within a first structure. The first structure disposed within a second structure in a subterranean environment. A radial symmetry is determined using the radial acoustic log. An eccentricity of the first structure relative to the second structure is determined based on the radial symmetry.

    Abstract: A system and method of detecting subsurface karst features includes receiving surface mapping data. A potential surface pad location can be identified in view of the surface mapping data. A resistivity survey for the potential surface pad location can be designed. The resistivity survey can include at least one long line extending through a surface hole for each of one or more wellbores in the potential surface pad location, and a short line extending through the surface hole of one of the one or more wellbores, each short line intersecting the long line substantially at the surface hole of one of the one or more wellbores. High resistivity areas exceeding approximately 150 Ohm per meter can be identified as sub surface karst features within the resistivity survey.
