Abstract
Systems and methods are provided for geosteering in directional drilling based on water detection. An exemplary method includes determining a signal-to-noise ratio (SNR) for an electromagnetic communication between devices on a bottom hole assembly, and determining a distance to water based, at least in part, on the SNR. Adjustments to geosteering vectors for the bottom hole assembly are determined based, at least in part, on the distance to water.
Claims25
A method for geosteering in directional drilling, comprising:
- determining a signal-to-noise ratio (SNR) for an electromagnetic communication between devices on a bottom hole assembly;
- determining a distance to water based, at least in part, on the SNR;
- determining adjustments to geosteering vectors for the bottom hole assembly based, at least in part, on the distance to water;
- and
- making the adjustments to the geosphere vectors to change a trajectory of a wellbore.
2 more elements
A system for geosteering in directional drilling, comprising
- a drill bit coupled to a bottom hole assembly;
- and
- the bottom hole assembly comprising:
- a coiled tubing drilling apparatus;
- at least two mandrels mounted on the coiled tubing drilling apparatus, wherein each mandrel comprises an electromagnetic communication device;
