7 of 12 offset wells had this problem here.
Recommendation
Pre-treat active system with sized LCM (CaCO₃ fine/medium, 15–20 ppb), keep MW ≤ 1.22 sg and reduce flow rate ~10% through the zone.
What worked before (NWS-16): Pre-treated active system with 15 ppb sized CaCO₃; reduced ROP to 10 m/h through the zone.

How NWIS works
- 01
Read the reports
OCR + NLP extract depths, events, actions and NPT from WCRs and DDRs, including old scans.
Open - 02
Build institutional memory
Every event, lesson and mitigation is searchable, with a link to its source page.
Open - 03
Correlate by formation
Offset wells are aligned by formation tops, not raw depth, so like is compared with like.
Open - 04
Alert ahead of the bit
As the live well approaches a known trouble zone, NWIS warns early and says what worked before.
