Description
Why is the GOR behaving that way? What is it telling me about the reservoir, or the completion? Why is this well different from that one? Are we pulling the well too hard?

The nature of linear flow into fractures in tight rock causes the GOR to behave much differently than in conventional reservoirs. The GOR may rise rapidly when the flowing bottomhole pressure falls below the bubble point; a GOR plateau may occur during a long transient flow period; and when boundary-dominated flow is underway, the GOR rises continuously. We will look at field examples from the STACK and SCOOP plays including Meramec, Woodford, and Springer Shale. Using reservoir simulation, we explain the reasons for a wide range of GOR behavior. Then we’ll cover some practical tools to help you recognize which stage of GOR performance your well is in, and the implications for forecasting production and estimating drainage volume. The presentation is based on SPE 184397, which was recently published in SPE Reservoir Evaluation and Engineering.
