Subsurface DNA Diagnostics uniquely measure fluid movement in the subsurface by extracting and sequencing DNA originating from microbial communities that survive in temperatures and pressures common to reservoir systems.
High-resolution studies into the subsurface DNA of the Delaware and Midland basins have returned millions of DNA sequences comprising thousands of unique DNA markers.
Samples to create a subsurface DNA baseline can be obtained through a low-risk, noninvasive workflow collecting well cuttings or reservoir fluids (oil, water and emulsions) during normal operations using collection procedures designed to preserve subsurface DNA.
The impacts of Subsurface DNA Diagnostics have been particularly noticeable during asset development, where the low risk, noninvasive workflow resolves a complex picture of the subsurface and detailed 4-D analysis of drainage height in stacked laterals.
The results identified out-of-formation production in each formation, and they were subsequently integrated with production data, reservoir properties and subsurface DNA to improve the learning rate for field development.
