Application of digital situational awareness in geosteering
Conventional geosteering becomes more complex, faster and requires more data in real-time. This puts an incredible amount of pressure on geosteerers as their decisions need to be taken in a shorter amount of time, need to be more precise and require from him/her analysis of a larger amount of data.
But that was not always the case.
A Historical Glance at Geosteering
Many of us remember that just roughly 20 years ago geosteering looked quite different. In the past, horizontal and deviated drilling was relatively simple, slower and allowed enough time to collect and interpret the data and select the direction of drilling. There were relatively fewer logs to look at and fewer changes of well’s inclination. Conventional geosteering decisions were first based on cuttings, and only LWD log streams like gamma-ray, density, and resistivity (non-azimuthal!) were streamed in real-time. Geosteerers (or well placement engineers) paid attention to negative and positive drill breaks and had very little information about the subsurface due to a very shallow depth of investigation of these sensors.
