💡 Operator Intent

Aggressive pad development with five wells (TOSCO BRANCH 2, 4, 6, 8, 10) on single pad.

Pad layout shows five well sites with shared infrastructure; directional planning shows anti-collision analysis with TOSCO BRANCH 4.
Wildcat exploration targeting Red River formation outside established State Line Field.

Operator affidavit argues geologic separation from existing field due to faulting; seeking new pool designation.
Minimal evaluation approach with decision to run casing based on open-hole log results at TD.

Permit states 'Marlo is not running any DST's or cores. They plan to evaluate... when they drill to TD and run open hole logs, at that time they will determine if it is prudent to run casing.'
Use of standardized, detailed drilling procedures with strict vendor control.

56-page drilling procedure mandates specific vendors, equipment, and protocols; requires use of 'only those vendors that are on Marlo Operating Company, LLC approved vendors list.'

🔧 Service Operator Relevance

Cementing and remedial work

Surface casing top job indicates potential cementing challenges; intermediate casing requires 2-stage cement job with DV tool.

Sample handling and shipping

Mandatory state sample collection with 30-day submission deadline creates immediate post-drilling service window.

Lost circulation materials

Drilling procedure anticipates losses in Dakota and Mission Canyon formations with specific LCM sweep protocols.

H2S monitoring and safety

Contingency plan assumes 100 ppm H2S with 3,000' radius of exposure; requires specific monitoring equipment.

Filter sock disposal

Regulatory requirement for leak-proof container on site from spud through flow-back; waiver requires sundry notice.
