Multiscale Structural Interpretation Services

Measurement integration for comprehensive 3D reservoir mapping

Interpretation of Deep-reading EM Data

Leveraging integrated multiwell measurements with various depths of investigation, our comprehensive multiscale structural interpretation services can enhance your decision making at every stage of the E&P life cycle—from guiding geosteering and confirming well placement to optimizing completions and field development strategies.

Measurable benefits to your operations

  • Advanced interpretation of data logging, allowing optimal results on data imaging, especially in challenging structural environments
  • Data accuracy and interpretation robustness in the subseismic-resolution range with an advanced 3D look around the wellbore
  • Superior results back to the reservoir space in the versatile Petrel E&P software platform

Services that reveal more reservoir detail

Our customized, actionable workflows are enhanced by high performance computing to provide scenario updates 20 times faster compared with traditional methods. Extract the maximum value from your borehole and reservoir measurements with

  • dip picking on the borehole image
  • structural analysis
  • true stratigraphic thickness (TST) correlations and fault-throw characterization
  • interpretation of deep-reading electromagnetic data
  • 3D near-well structural modeling.
Formation dips picked on LWD density borehole image
Formation dips are picked on an LWD density borehole image. Resulting bed boundary dips are upscaled so they can be compared and combined with GeoSphere reservoir mapping-while-drilling service and surface-seismic scale of interpretation.
Tar mats (red outlines) observed in logs near the oil-water contact were incorporated in the dynamic aquifer model as potential barriers to fluid flow between the reservoir and the aquifer. Multiple history-matched realizations increased confidence in predictions.

Two Schlumberger Workers Reviewing Data on Monitors

Standard services

Three-step workflow with LWD imaging and structural analysis.

Data loading and quality control
Software used to load and QC data enables accurate location of outputs, including dips, formation tops, faults, and surfaces in 3D space.

Dip picking
From the borehole image, we perform a manual dip picking of sedimentary and tectonic features.

Structural analysis
We then characterize major tectonic structures—such as monoclines, folds, and unconformities—based on arrow plots, dip vector plots, and stereonet plots of the bedding dips.

Advanced services

True stratigraphic thickness correlations and fault-throw characterization
To improve the correlation process, we compute TST and stratigraphic drilling polarity. Major faults are among the first fractures characterized by structural analysis, and TST correlations enable us to estimate the amount of missing or repeat sections introduced by the fault throw.

Interpretation of formation surfaces from deep-reading EM
As part of the advanced workflow, we can log the borehole image in combination with a deep-reading EM such as the GeoSphere HD high-definition reservoir mapping-while-drilling service, which maps a depth of investigation that exceeds 250 ft [76 m]—the largest in the industry.

3D near-well structural modeling
As a final step 3D, modeling is applied to a single well or multiple wells.
