In this presentation, we will discuss some key insights that can be obtained from drilling data to help better characterize and understand the reservoir. These include changes in lithology, inferring rock strength, identifying, and quantifying localized depletion caused by offset producers, fracture detection both natural and induced, and how completions interact with various geohazards. We will also explain how this information can be collected and ultimately used to make decisions on items like optimal drilling target, stacked pay development, and even well spacing.
Specifically, we will look at four applications of how the drilling data can be used. 1) Using rig drilling data to estimate rock strength. 2) The use of rig data, gamma ray logs and geosteering to predict natural fractures. 3) The use of rig drilling data and mud gas logs to identify localized fracture depletion. 4) Understanding hydraulic fracture growth in stacked plays and around geologic features.
Several case studies will be presented that demonstrate the accuracy and applicability of this data, with a focus on using the data to make actionable decisions, as well as some of the data limitations. At the conclusion of this talk, the importance of incorporating drilling data from every well to improve reservoir knowledge will become evident. Even more so when considering this data is readily available, on every well, and is obtained at a very low or no cost, and with no associated operational risks.
