How Leveraging a Digital Oilfield Leads to Improved Operations

Different issues addressed during well optimization.

A mechanical issue in a well is a common occurrence, but issues found in more than one well could indicate a larger problem within the reservoir. To avoid reservoir dilemmas that can hamper well-placement strategies and incur long-term costs, analysts need a complete visual of the reservoir. To prevent operational stalls, analysts also need accessible digital information that allows them to see the inner-workings of the drilling process. In addition, digital information is vital to develop viable strategies needed to optimize well-placement plans.

A digital oilfield offers a solution to these visual dilemmas. By opens in a new windowintegrating multidisciplinary data into one central, digital viewing system, reservoir conditions can be visualized in their entirety, guiding operators throughout well-creation campaigns. The integration of these data also offers an in-depth look at multiple wells in a single area, helping drillers navigate an area properly without colliding with existing wells and mitigating risks that can stymie production.

Prevention of Well Catastrophes

While there is no guaranteed way to avoid well disasters, operators can opens in a new windowreduce the likelihood of operational mishaps via digital data integration. Operators know more than anyone about the complexities of well-placement campaigns, especially when drilling horizontally, which is why they need a visual system that provides a comprehensive scope of a reservoir profile.
With a digital representation of the reservoir, analysts can cross-correlate data points and make connections between multiple wells. For instance, drillers may encounter a mechanical issue within a single well, but software that detects the same issue in other wells can highlight a larger quandary within the reservoir, giving operators a chance to address overarching obstacles instead of spending valuable resources fixing a single well. By relying on software that works with in conjunction with the digital oilfield, users can save time and money by addressing the root causes of reservoir roadblocks.
Operators can also buffer digital data by integrating various datasets that include engineering, petrophysical, geophysical, and geologic data—affording users a window in which they can view reservoir attributes, including individual wells that may show signs of dysfunction. And, the merging of different data streams fosters collaboration between departments where all teammates can assess centralized data points and understand the full scale of a reservoir or well in question.

4D Analytical Benefits

The ability to opens in a new windowvisualize seismic data in the fourth dimension—or as it changes over time—is a vital asset that is further enhanced when integrated with other pertinent reservoir data. It is especially useful for the monitoring of mature oil fields, which produce complex and high-volume datasets that require further study and analysis. 4D can also be used to track fluid or pressure variations that can stop production goals or cause safety hazards.
For example, analysts can analyze a 4D seismic grid that consists of a baseline survey and another survey post-production to determine the source of a gas kick. The team can combine well log and wellpath data to achieve additional context into the well. The user can filter the grid differences to pinpoint potential sources of the kick (i.e. pressure irregularities) and rely on data from neighboring wells to determine if the reservoir is experiencing pressure fluctuations that were previously undetected. Or, the team could read an abnormality near an injector well that could have caused the gas kick to occur. Regardless, the ability to see aberrations could not be possible without a 4D visualized environment. Otherwise, users would be stuck with conventional seismic data visuals that may have concealed factors resulting in the gas kick.

4D visualization allows users to:

  • view the abrupt changes of reservoir conditions
  • comprehend the behavioral patterns of the reservoir
  • make faster decisions in response to unforeseen events
CoViz 4D, an integrated software solution, offers these capabilities by merging surface and subsurface datasets in a 4D seismic viewer that includes time-lapse seismic volumes, including other datasets such as 4D reservoir simulations, production data, drilling obstacles, and geological models. CoViz 4D has the ability to render 4D datasets into graphical or animated temporal forms, ensuring that all visual aids are kept evergreen with an ongoing stream of current data. As a result, users receive the latest information about a reservoir, nurturing an analytical process that can navigate oilfield difficulties.

Digital Oilfield Visualization and Analysis with CoViz 4D

Data visualization software such as CoViz 4D gives analysts a larger scope of reservoir conditions. While operators may be focused on a single well, they may not realize that the well is symptomatic of a profound reservoir problem, leading to unstable output from other wells. From there, operators can make better management choices in response to reservoir changes, including sudden hazards that may stand in the way of maximum hydrocarbon extraction goals.

Data visualization software such as CoViz 4D gives analysts a larger scope of reservoir conditions.

CoViz 4D maximizes the opens in a new windowvisualization and analysis of a digital oilfield by integrating diverse datasets into one central viewing system. Its 4D capabilities further enhance the resolution of seismic surveys, giving users greater insight into well conditions or subsurface reservoir qualities that may harbor underlying impediments. By leveraging CoViz 4D, operators can focus on the most important goal, which is the creation of the best positions and wellpaths in the most lucrative areas of an oilfield.
