Using a 3D-earth-model visualization as a foundation, a new information-tec
hnology (IT) development strategy focuses on perceiving "drilling learning"
by an intuitive method. Symbols known as "knowledge attachments" are attac
hed to each wellbore trajectory displayed in the 3D environment, with each
symbol indicating a specific event related to drilling operations. This rep
resentation makes interdependencies between the earth model and drilling op
erations evident.
