7.5.1 Business Purpose

Data captured and transferred using the wellbore markers object has these uses:

• Helps with drilling planning and operations; for example:

• Guide geosteering (the act of adjusting the borehole position (inclination and azimuth angles) “on the fly” while drilling a borehole) to reach one or more geological targets, when encountering obstacles that require deviation from the drilling plan.

• Optimize drilling operations based on the formation angle, for example, a horizontal reservoir could be better exploited with a horizontal well.

• Helps with assessing hydrocarbon potential and reservoir quality, by contributing information to determine:

• Chronostratigraphic age. The maturity of the formation is useful information in estimating the potential of source rock (where hydrocarbons were initially produced).
• Formation angles (dip information) and continuity of the reservoir based on the depth and angles of the formation in different wells.

• Sequence stratigraphy, which is important in identification of a petroleum system and its potential for production of hydrocarbons.
