Now the advent of rotary steerable tools and an ever-increasing arsenal of geophysical tools enables well placement with ever-increasing accuracy. Typically a basic tool configuration will have directional and inclination sensors, along with a gamma ray tool.
The use of rotary steerable tools and an expanding array of geophysical tools has made it possible to place wells with greater accuracy. A standard tool configuration typically consists of directional and inclination sensors, as well as a gamma ray tool.
