📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 3	Operator requested and received waiver from open hole logging requirements, leveraging offset well data to establish formation tops. 📄 Well Sundry Form - Request for Consideration/Waiver Demonstrates proactive regulatory strategy to reduce well construction costs and time by avoiding redundant logging.	2026-06-17	Regulatory / Permitting
Tier 3	Operator requested significant MAIP increase from 1318 psi to 2459 psi shortly after well completion, based on Hazen-Williams friction calculations.⏰ TIME-SENSITIVE 📄 Well Sundry Form - Maximum Injection Pressure Increase Immediate post-completion pressure uprate indicates either initial design conservatism or discovered higher injectivity, enabling higher throughput.	2026-02-20	General Oilfield Services
Tier 3	Pressure test of high-pressure injection line (4" Flexsteel 2250 psi) performed at 2250 psi for 30 mins, exceeding permitted MAIP at the time. 📄 Well Sundry Form - Notification of Work Performed Line tested to pressure above initial permitted MAIP, indicating infrastructure built for future pressure increases.	2026-02-04	General Oilfield Services
Tier 3	MIT performed and passed on 2025-12-30, with next test due in 5 years (2030-12-30), establishing well integrity baseline.⏰ TIME-SENSITIVE 📄 Well Integrity Report Early MIT pass establishes operational confidence and sets a long-term compliance calendar.	2025-12-30	General Oilfield Services
Tier 3	Tank diking variance approved contingent on submission of as-built schematic, indicating non-standard containment design. 📄 Permit Stipulations Regulatory granted flexibility on containment sizing suggests operator negotiated based on pad-wide containment strategy.	2025-10-08	General Oilfield Services

💡 Operator Intent

To develop a high-capacity, pad-focused saltwater disposal facility with integrated infrastructure.

Well is co-located with five producing wells on the same pad; UIC plan states intention to only inject water from on-pad wells; facility design includes shared containment and monitoring.
To optimize injection efficiency and maximize disposal rates through pressure management.

Immediate application for MAIP increase post-completion, coupled with over-built line pressure rating, indicates a focus on maximizing injection volume and reducing backpressure.
To leverage existing data and regulatory precedents to reduce well construction time and cost.

Successful waiver of open hole logs based on offset well data; use of existing geotech and sample data from nearby well in UIC application.

🔧 Service Operator Relevance

High-Pressure Pumping & Flowline Services

MAIP increased to 2459 psi, indicating need for high-pressure injection pumps and flowlines rated for sustained operation above 2200 psi.

Well Integrity Testing & Monitoring

MIT passed with next test due in 2030, but ongoing monitoring likely required for high-rate injection; pressure and vibration monitoring referenced in SCADA.

Facility Construction & Earthwork

Pad involved significant cut/fill (over 100k cu yds); future pads for operator may require similar large-scale grading and containment construction.

Regulatory & Permitting Support

Operator actively pursues waivers and variances (logging, diking); specialists can assist in navigating similar requests for efficiency gains.
