Abstract
A method and system are geosteering in coiled tubing directional drilling. In an exemplary method, a response from a gas sensor disposed on a bottom hole assembly is measured and a gas parameter from the response is determined. A trend in the gas parameter is determined. Adjustments to geosteering vectors for the bottom hole assembly are determined based, at least in part, on the gas parameter, the trend, or both.
Claims25
A method for geosteering in coiled tubing directional drilling, comprising:
- measuring a response from a gas sensor disposed on a bottom hole assembly;
- determining a gas parameter from the response;
- determining a trend in the gas parameter;
- and
- determining adjustments to geosteering vectors for the bottom hole assembly based, at least in part, on the gas parameter, the trend, or both.
A system for geosteering in coiled tubing directional drilling, comprising:
- a coiled tubing drilling apparatus comprising:
- a bottom hole assembly comprising a mandrel;
- and a drill bit;
- and
- a gas sensor disposed on the mandrel to measure a parameter of fluid flowing outside the mandrel.
