Geosteering Features

Interpretations using StratCORR

StratCORR will allow you to make dynamic stratigraphic correlations, enhancing your reservoir understanding while drilling. Use StratCORR to calculate apparent dip, adjust structures and isopachs and improve your current interpretation of your target formation. Interpretation points created by StratCORR participate in 3D modelling, which may result in structural changes. By having an increased understanding of where you are and what is ahead of the bit, users can be more confident in decisions on where to go next.

StratCORR has the ability to recall saved correlations for reinterpretation and information retention. Correlations can be made using multiple reference offset wells, and the recalled correlations will adjust to the appropriate reference well. Easy access to historical information helps you get the best well placement, and increases your knowledge-base for future wells.

The video shows you how to use the StratCORR feature of SMART4D to:

  • Add interpretations intuitively.
  • Update interpretations easily.

Dynamic Profile

SMART4D’s unique Dynamic Profile tool displays a vertical cut through the property model along the horizontal well path. It is as if a vertical well were drilled along the well path, and the property (gamma, porosity or otherwise) is predicted from the model. This feature is particularly useful during the landing to view the approach of important structural markers and the true vertical depth (TVD).

The animation shows the horizontal panel with a dynamic profile of the gamma model. The green and red dots on the Dynamic Profile represent the driller’s plan and actual trajectory respectively.

Model Dip Prognosis

The prognosis for the apparent dip of the target formation is automatically calculated along the length of the driller’s plan well prior to drilling. This gives the user a realistic pre-drill understanding of the formation. Once drilling begins and the model is adjusted, the apparent dip is continuously updated both along the actual trajectory and ahead of the bit, helping the geosteerer proactively adjust upcoming decisions on well placement.

Target Planner

The Target Planner allows Geologists to dynamically design way-points within the SMART4D Panels. Users move the way-point position to desired geological sweet spots, while getting live feedback on the proposed dogleg serverity (DLS). The way-point position changes colour based on severity of the dogleg. The ranges can be customized based on well goals, for example 0-3 DLS is desired (green), greater than 3-6 is to be avoided (orange) and over 6 is not acceptable (red).

By managing the way-point design, every recommendation to the directional team will be within the driller’s achievable targets reducing overall DLS and tortuosity of wells. In larger drilling programs, we have observed over 25% decrease in the cumulative DLS from ICPs.

Azimuthal and Synthetic Wellbore Imaging

Create wellbore imaging using azimuthal gamma and resistivity tools (2, 4, 8, 16 or 32 tracks) with the SMART4D Geosteering Panels. In the wellbore image you can see the smiles and frowns, as well as the contrasts in the wellbore, to calculate dip. Geosteering with a well-bore image in real-time while-drilling using data acquired through WITSML or static import. Furthermore, using SMART4D Geosteering Software you can develop a synthetic wellbore image of Gamma, Resistivity, Porosity or other 3D property models improving interpretations for geosteering or modelling.

Seismic Image

The 3D seismic underlay tool positions a seismic section along the horizontal well path using georeferencing. While finalizing driller’s plans within SMART4D, the seismic underlay adds insight into the proper well placement. During drilling, the seismic image can be used in conjunction with the property model to ensure the well is within the target zone.
