Caveat Contemplor--Determining Success of a Horizontal Well
Requires: Assessing if Basic Criteria was Accomplished
- Where it is drilled...
- geology - structure & stratigraphy
- Why it is drilled...
reservoir & drive mechanism
- What it is drilled for...
- How it is drilled...
- well design, drilling, & completion
Operator Reporting Prevents Accurate Assessment
- Inaccurate
- Incomplete
- Non-existent
