Why Geosteer a Horizontal Well?



THE QUESTIONS:

• How will geosteering a horizontal wellbore save drilling dollars?

• What can be learned from a horizontal wellbore about the geology in an area that we

don’t already know from vertical wells and seismic?

• Are there “sweet spots” we should target?

• How can Post Drill Analysis of horizontal Wellbores that have already been drilled improve the performance of new wells?

• How do we use the geologic interpretation of data from a horizontal well to improve

completions?


BENEFITS OF GEOSTEERING

GEOSTEERING IS ABOUT MORE THAN JUST STAYING IN ZONE

• IT’S ABOUT SAVING DRILLING DOLLARS

• Landing the curve into the correct stratigraphic position the first time

• Drilling hazard avoidance! (i.e. slow drilling zones)

• Prevention of sidetracks due to incorrect targeting because of unexpected geologic

hazards such as:

• Faults cut in the build section • Anomalous dips through the build section

• IT’S ABOUT UNDERSTANDING THE GEOLOGY

• TSPM shows you all the warts. Details that can be seen in no other way. (Small faults,

anomalous dips, stratigraphic variation)

• Every area has its own unique characteristics that can be planned for if they are known

• Identifying Karsted and Faulted areas

• The only way to identify “sweet spots” in the formation is to know which section each well drilled


IT’S ABOUT UNDERSTANDING WELL PERFORMANCE

• Post Drill analysis of poor wells can reveal re‐drill opportunities

• Post Drill analysis of excellent performers may identify “sweet spots” within the reservoir

• Analysis of the structure and stratigraphy will give the operator a better understanding of reservoir performance versus reservoir placement
