Well Intercept Sub-Committee

Mission

Develop good practices in well intercept scenarios and promote its adoption in the well construction industry.

About

The SPE WPTS/ISCWSA Well Intercept Sub-Committee has officially released the WISC eBOOK R4 (2026). This comprehensive update covers the latest applications and good practices in wellbore ranging technologies and interceptions.

Work Group Project Milestones

  1. Final Draft Feedback

1.      PMR – Add statement that metallic tubular (BHA, Casing or drill pipe) must be present in the target borehole.

2.      Section 2.6.4 Magnetized Casing to Improve PMR – Add statement that magnetized casing is the same technique as residual magnetization therefore it classified as PMR.

3.      Section 8.5.1 Gyro Survey Requirements – Add new paragraph, discussion on while drilling magnetic ranging deployment and GWD relative position in the BHA.

4.      Section 1.2 Magnetic Ranging Techniques – rewrite, remove Acoustic Ranging text

5.      Section 1.3 Acoustic Ranging Techniques – rewrite, remove Magnetic Ranging text
