With easily recoverable oil either gone or continuously depleting, operators are evaluating previously-drilled leaseholds to determine if there are opportunities for further economically-feasible recovery through the recompletion of oil and gas wells. Improvements in production technologies and the ability to translate volumes of data obtained over the life of a reservoir into meaningful 3D visualizations that depict changing subsurface conditions have allowed operators to discover ways in which drilling costs can be reduced and more oil and gas recovered than originally indicated.
Visualize Subsurface Conditions to Guide Recompletion of Oil and Gas Well Strategy
Compare Well Performance Against Similar Offset Wells
- Is proximity to other producers impacting pressure and flow?
- Has a recent seismic survey that is now reachable via sidetracking?
- What recompletion methods have been used successfully to boost production in nearby wells or wells with similar geologic and geophysical conditions?
- Are they “stacked pay zones” that can be produced, or is time to move on, now that the single geologic layer has been depleted?
Determine the Appropriate Recompletion Methods
Acid strength and corrosiveness of the acid mixture
Environmentally better approach and lower cost, in comparison to hydraulic fracturing
Ability to monitor the process to avoid gas leaks or related problems
Ideal for mitigating near-wellbore damage, e.g., dissolving pore lining material
Requires an after-flush (additives and solvents) to avoid crude emulsification caused by acid byproducts
Determine pumping pressure, need for proppants
Monitor fracture development and extent with microseismic surveys
Determine if new injection wells should be drilled or if abandoned wellbores can meet the need
Gas, water, or steam?
Visualization: Confidently Determine Recompletion Needs
Reservoir engineers gain a far more detailed understanding of reservoir dynamics by using software that integrates relevant data associated with oil and gas wells.
CoViz 4D, a data visualization analytics software from Dynamic Graphics, Inc., gives geologists, geophysicists, and reservoir engineers the ability to easily access and combine all relevant data associated with subsurface environments. Powerful analytic capabilities enable users to explore data relationships, analyze the accuracy of depth conversion of 3D seismic, and visualize seismic well ties and velocity models to facilitate decisions that positively impact profit and reduce operational risk.
