Re-Plumbing the 100 Year Old Pennsylvanian Bartlesville y Sandstone Reservoirs in NE Oklahoma in NE Oklahoma Tulsa Geological Society April 12, 2011 Tulsa, Oklahoma Tulsa, Oklahoma Bob Westermark Grand Directions, LLC
Today’s Agenda y g • Questions and Answers Questions and Answers • DOE Wolco Project • Grand Directions’ Avant/Wolco Project G d Di ti ’ A t/W l P j t • What would we do differently?
How ? How do I plan for a successful How do I plan for a successful horizontal well? • Drill for by-passed oil • Understand the depositional environment • Understand the depositional environment • Keep the cost down • Closely monitor the results • Closely monitor the results • Modify the mental model
Is there enough oil left? g
Where to drill? Where is the remaining oil in my Where is the remaining oil in my depleted reservoir? Understand the Depositional Environment • Structure and isopach maps • Fracture orientation • Paleo-topographic map
Why Spend the Money? y p y To make money! To make money! • Geologic model Geologic model • Reservoir model • History matching of past performance • History matching of past performance • 3 dimensional, 3-phase black oil simulator
Once a history match is achieved is achieved, an economic analysis i is performed f d to determine viability.
Was your last horizontal well What is the Cost? expensive? expensive?
Before w orrying about cost . . . Let’s define a few drilling terms. g y
Definitions Section View Plan View Plan View Build Rate Build Rate End of Curve Orientation Length g Kick Off Point
What Determines Build Rate For Horizontal Wells? Schlumberger Power Drive Rotary Steerable Assembly Mud Motor + MWD + LWD = 10 to 30 degrees per 100’
What does Grand Directions use? Rotary steerable assembly y 90 degrees per 100’ y
What does Grand Directions use? Reduce the cost of horizontal wells Reduce the cost of horizontal wells. Rotary steerable assembly Rotary steerable assembly
What does Grand Directions use? Reduce the cost of horizontal wells. Reduce the cost of horizontal wells Air hammer
