North Slope Fields & Source Rocks
Not all oil is the same…
Elements needed to make a Petroleum Field
• Already discussed:
• Reservoir rock (container to hold petroleum)
• Source rock (where the petroleum comes from)
• Other Elements needed:
Migration (have to move petroleum from source to reservoir)
Trap/Seal (how to keep oil &/or gas in reservoir rock)
How to get Petroleum out of the ground…Drilling Wells
Industry Drilling Envelope
Wells in the Liberty Field will have a horizontal departure of 6‐8 miles. This is equivalent to the distance from the Port of Anchorage to Huffman Road.
Vertical Multi‐lateral Horizontal
Ultra Extended Reach
