Next week, October 14-19 is the Society of Exploration Geophysicists International Exposition and 88th Annual Meeting in Anaheim, California. Many members from the Emerson Exploration & Production Software team will be there to present to the attendees. Let me highlight a few of the lunch and learn sessions.
On Monday, October 15, Henry Posamentier will present, Seismic Geomorphology – Mitigating Lithology Prediction Risk and Providing Context for Further Investigation: Applications and Workflows. Here’s the session abstract:
As high-quality 3D seismic data has become widely available, our ability to predict the subsurface distribution of lithologies has significantly improved. Stratigraphic interpretation of seismic data involves the integration of stratigraphy and geomorphology, with integrated section and plan view images yielding robust interpretations of stratigraphic architecture and associated lithologies.
Geologically-meaningful seismic patterns can be recognized in multiple domains, including section views, plan views, 3D perspective views, and animated (i.e. movie) views. Once such patterns have been identified, interpreters can populate these patterns with appropriate lithologies. Seismically-derived geologic interpretations can have significant impact on exploration and production in the following ways:
Geology: 1) prediction of lithology, 2) prediction of compartmentalization, 3) development of depositional analogs, 4) enhanced understanding of geologic processes.
Geophysics: 1) provides depositional context for geophysical analyses (e.g., DHI analysis, reservoir properties from seismic). Understanding geologic context can provide a “reality check” when evaluating geophysical data for rock and fluid properties. 2) Quality control for geophysical processing. Evaluating the quality of seismic images, especially in the plan view domain, of known geologic features can help determine the value of a given processing step. Ensuring that meaningful geologic features are not processed out of the data is critical to maximizing the value of seismic data.
Examples will be given from deep marine as well as shallow marine and non-marine environments, illustrating how patterns observed from multiple seismic domains can lead to robust geologic interpretations and predictions of lithology. Critical workflows designed to efficiently “mine” 3D seismic data will also be illustrated.
On Tuesday, Emerson’s Hassane Kassouf will present Unconventional Field Development in the Cloud. Here’s his abstract:
Pervasive inefficiencies are weighing down unconventional field development operations. In 2017, well completion was still the second largest overall cost, accounting for over 25% of the total services expenditure.
This presentation explains how you can accelerate your organization’s digital transformation to eliminate remaining inefficiencies. We will demonstrate use cases of unconventional field development that leverage the digital shift enabled by cloud computing. At the core of this transformation is Emerson’s secure, independent, open ecosystem with decision-driven cloud native applications. Some are custom written for well placement and completion optimization.
The presentation will include alternative non-siloed approaches that incorporate seismic, microseismic, well, and diverse reservoir data for rapid and inclusive decision making. Combining reservoir intelligence such as modeling aided by machine learning, with the power of IIoT, makes it possible to improve performance by making remedy, maintenance and optimization decisions predictively.
Cloud applications are enabling a new digital operations model where accessibility, mobility and real-time decisions are placed at the core of field development, resulting in unparalleled operational performance.
On Wednesday, Norm Neidell will present, Holographic Processing and Imaging Yield Highest Possible Seismic Resolution. Here’s his abstract:
Images representing the subsurface formed from exploration seismic data are an essential element of many, if not most exploration and production activities. For the last 40 or more years, such images have used the technology of signal processing, both implicitly as in acquisition design, and explicitly in forming the displays. This approach has proved quite effective, but also embodies many recognized limitations. For example, the Nyquist limit as applied affects attainable resolution, and the propagating wavelet loses frequencies with time or distance, and hence reduces resolution even more rapidly with recording time.
However, other technologies for forming images from the same data are available. One of these methods, Holographic Imaging, offers significant advantages for most seismic data applications. Holography seeks to image the subsurface in terms of reflectivity, rather than only imaging reflections from the subsurface. Resolution increases approach factors of 5, while also employing novel Extended Visibility Dynamic Range (EVDR) color displays scaled in interval velocity, increases interpretive perception by factors approaching 30. This methodology is available from Emerson E&P Software as a geoscience service.
A number of illustrative examples will be presented as the methodology is described. Both conventional and unconventional objectives are addressed as well as carbonates and clastics. The method also can offer reduced acquisition costs approaching 50%, by employing survey designs which take better advantage of survey data multiplicity, and inherent sampling properties of the Holographic method.
