📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 3	Casing integrity test performed to isolate wellbore in preparation for re-entry/re-drill sidetrack. Test passed and witnessed by NDIC inspector.⏰ TIME-SENSITIVE 📄 SUNDRY FORM FOR WELL FILE NO.: 11920 DESCRIPTION (OPERATOR) Confirms the operator is actively preparing the well for the sidetrack operation, verifying wellbore integrity is a critical pre-drill step.	2025-10-01	General Oilfield Services
Tier 3	Plugging report shows tubing and production casing removed, plug set, and test passed. Plugging contractor was Magnum Cementers. 📄 WELL COMPLETION OR PLUGGING REPORT FOR 11920, Page 1 and Page 2 Documents the completion of the initial plugging phase of the work plan. Identifies the specific plugging contractor used.	2025-08-28	General Oilfield Services
Tier 3	Operator intends to plug back well to +/-3500', cut & pull top 3500' of 5.5" casing, and set a balanced kick off plug for sidetracking and re-drilling well to Red River.⏰ TIME-SENSITIVE 📄 PLUGGING SPECIFICATIONS section of Sundry Form 264521 Reveals a planned re-entry and sidetrack operation, not a simple plugging. This is a work plan for future drilling activity.	2025-08-26	Directional Drilling
Tier 3	Well is located in a Missouri River floodplain, with a documented history of being shut-in due to flooding and ice jams (2018, 2015, 2014, 2012, 2011, 2010, 1995). 📄 Multiple Sundry Form 4 entries and a 2014 flood preparation letter from NDIC. The location presents a persistent environmental and access risk that affects operations timing, requires flood preparedness, and may influence facility design.	Relative	General Oilfield Services
Tier 3	Well has a history of repeated, costly interventions due to casing collapse in salt formations (Prairie Salt, Dunham) and salt plugging, leading to previous re-completion attempts and workovers. 📄 Multiple Sundry Form 4 entries from 1999, 1994, and earlier describing workovers and failures. Highlights persistent geomechanical challenges (salt flow) that compromised the original wellbore, justifying the current sidetrack plan to bypass damaged intervals.	Relative	Drilling Rigs

💡 Operator Intent

To sidetrack and re-drill the well to the Red River formation, abandoning the old wellbore due to persistent casing and salt flow problems.

The plugging specifications state: 'The objective of this project is to plug back the above referenced well to +/-3500', cut & pull top 3500' of 5.5" casing, and set a balanced kick off plug on top of the remaining 5.5" casing stub for use in sidetracking and re-drilling well to Red River.'
To maintain or establish production from the Red River formation, which was the original deeper target, after previous attempts to produce from the Duperow and address Red River problems failed.

Historical documents show the well was originally completed in the Red River (1986), had workovers to try to re-stimulate it (1994, 1999), and was later produced from the Duperow. The current plan explicitly aims to 're-drill well to Red River.'

🔧 Service Operator Relevance

Plugging & Abandonment / Well Decommissioning

The initial plugging phase to set the kick-off plug was completed in August 2025 by Magnum Cementers. However, the full sidetrack operation is pending, which may involve additional plugging or abandonment of the old lateral.

Directional Drilling & Sidetracking Services

The operator's approved plan is to sidetrack off the kick-off plug and re-drill to the Red River. This is the next major phase of the operation.

Casing Cutting & Pulling Services

The plan specifies cutting and pulling the top 3500' of 5.5" casing. This work is part of the preparation for the sidetrack.

Cementing Services (Primary and Balanced Plug)

The procedure requires setting a balanced kick-off plug and other cement plugs. Cementing is critical for well integrity and sidetrack initiation.

Drilling Rig & Related Services

A drilling rig will be required to perform the sidetrack and re-drill to target depth. The plugging report states: 'RDMO and wait for drilling rig to sidetrack off of kick off plug and re-drill well to TD.'
