Oil Well Due Diligence for Development Projects
Helping developers identify subsurface oil well risks before they become feasibility, permitting, or construction problems.
Terra-Petra helps developers, property owners, attorneys, and buyers locate, evaluate, and assess abandoned oil wells in the Los Angeles area, throughout California and the United States.
From desktop review through field investigation and CalGEM coordination, we help clients understand risk early and move projects forward.
The Oil Well Isn't The Problem. The Unknown Liability Is.
Many properties contain mapped oil wells that are inaccurately located, improperly abandoned, or poorly documented. These conditions can delay transactions, impact project design, trigger regulatory requirements, and create uncertainty during due diligence.
The sooner the risk is understood, the more options are available.

The Real Problem
Urban Infill vs. Legacy Oil Fields
Across Southern California—particularly throughout Los Angeles, Orange County, and the Inland Empire—prime real estate frequently sits directly on top of historic, unmapped oil fields. Discovering an undocumented or improperly abandoned well after land acquisition can instantly throw a wrench into your project’s economics. If a legacy well footprint is flagged during a municipal plan check, building departments will freeze your permits on the spot.
Undocumented oil wells and subsurface spatial conflicts create cascading issues for project teams, directly impacting:
- Site Feasibility & Land Acquisition: Determining actual buildable footprints under strict local setback ordinances before closing on a parcel.
- Entitlements & Environmental Review: Clearing mandatory California Environmental Quality Act (CEQA) reviews and local environmental site assessments.
- Building Permit Clearances: Resolving sudden plan-check rejections or holds from the Los Angeles Department of Building and Safety (LADBS) and regional building departments.
- Construction Schedules & Budgets: Preventing costly field stand-downs for grading crews due to unexpected subsurface metallic obstructions.
- Project Cost Forecasting: Factoring in the major structural and financial weight of forced oil well re-abandonments before budgets break.
Getting out ahead of these subsurface liabilities early gives your team the runway needed to engineer around them.
