Geosteering: The Past and The Future

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.

In the past, horizontal (or near-horizontal) drilling was relatively simple, slower and allowed enough time to collect and interpret the data (fewer logs) and select the direction of drilling (inclination of the well). Many of us remember that just roughly 20 years ago geosteering looked quite different.

Conventional geosteering decisions (shale oil and gas geosteering is a totally different story which I will cover in another article) were first based on cuttings, and only a few LWD log streams like gamma-ray, density, and resistivity (non-azimuthal!) were added later.
