## Page Highlights

**Geographic Concentration:** Holmes Western Oil's recent activity is exclusively in California, with Kern County representing 69% of activity records and Fresno County accounting for 31%.

**Formation Targeting:** The operator focuses on two primary formations—Monterey-Temblor (7 records) and San Joaquin Basin (6 records)—both conventional plays in California's Central Valley region.

**Permit Timeline:** The 13 permits span from August 2024 to July 2026, with notable permitting activity in early 2025 (4 permits in January) and mid-2025 (multiple Santiago Creek Unit wells).

**Well Types:** All permits appear to be conventional vertical wells, with only one permit (Santiago Creek Unit 7-Era) showing a 534-foot lateral length.

**Activity Indicators:** The zero counts for recent spuds, new producers, and DUC inventory suggest the operator may be in a permitting phase without immediate drilling or completion activity.

**Santiago Creek Unit:** Multiple permits target the Santiago Creek Unit in Kern County, indicating potential development of a specific field or lease position.
