ar-aogc

Arkansas Oil and Gas Commission (AOGC) Data Skill

Accesses Arkansas oil and gas regulatory data from the AOGC. While Arkansas is a smaller oil and gas producer, it is ground zero for U.S. lithium-from-brine development. The south Arkansas Smackover Formation hosts the highest known lithium concentrations in U.S. produced waters and has attracted major DLE (direct lithium extraction) investments.

API Key Handling

No API key required. AOGC data is publicly accessible. However, the AOGC has limited online data infrastructure compared to major producing states.

Important: The AOGC website (www.aogc.state.ar.us) has restricted automated access (403 responses to standard web crawlers). Manual browser access or specific data request workflows may be necessary.

Data Access Architecture

The AOGC provides data through three channels:

1. AOGC Website — well data, production reports, permit records, orders
2. B-19 Production Reports — annual production reporting by operators
3. Cross-Reference Sources — USGS databases, academic literature, and company filings contain more detailed Smackover brine data than AOGC itself

Channel 1: AOGC Website

Base URL: https://www.aogc.state.ar.us/

Resource	URL/Path	Data
AOGC Home	https://www.aogc.state.ar.us/	Main portal with navigation to data
Online Services	https://www.aogc.state.ar.us/onlineservices.htm	Links to data query tools
Well Data	https://www.aogc.state.ar.us/welldata.htm	Well records and search
Production Reports	https://www.aogc.state.ar.us/production.htm	B-19 production data
General Rules and Orders	https://www.aogc.state.ar.us/rules.htm	Regulatory orders
Forms	https://www.aogc.state.ar.us/forms.htm	Filing forms (W-2, B-19, etc.)
GIS Maps	https://www.aogc.state.ar.us/gismaps.htm	Well location maps

Channel 2: B-19 Production Reports

Arkansas operators file annual production reports on AOGC Form B-19. These contain:

• Well identification (API number, well name, operator)
• Annual oil production (barrels)
• Annual gas production (MCF)
• Annual water production (barrels)
• Formation
• Well status

The AOGC may make B-19 data available through their online services portal. Availability and format may vary.

Channel 3: Cross-Reference Sources (Critical for Li/Mg Research)

Because AOGC's online data infrastructure is limited, the most useful data for lithium/brine research comes from cross-referencing AOGC well records with:

Source	What it provides	How to access
USGS Produced Waters Geochemical DB	Li, Mg, TDS, full brine chemistry for AR wells	usgs-produced-waters skill
USGS Mineral Commodity Summaries	National Li production/reserve estimates	usgs-minerals skill
Standard Lithium SEC Filings	Reserve estimates, DLE performance, pilot results	SEC EDGAR
ExxonMobil Lithium Announcements	Magnolia, AR project details	Company press releases
Equinor Lithium Project	South AR Smackover lease data	Company announcements
Academic Literature (Collins, 1976)	Foundational Smackover brine chemistry data	pnge-literature skill (USGS Pubs + OSTI adapters)
NETL EDX	DOE-funded research on Li from produced waters	netl-edx skill

# For well data access:

# Option 1: Browser-based access
# Navigate to: https://www.aogc.state.ar.us/welldata.htm
# Search by API number, operator, county, or formation

# Option 2: AOGC GIS Maps
# Navigate to: https://www.aogc.state.ar.us/gismaps.htm
# Interactive map with well locations

# Option 3: Direct data request
# Contact AOGC directly:
#   Phone: (501) 683-5814
#   Email: [email protected]
#   Address: 301 Natural Resources Drive, Suite 300, Little Rock, AR 72205

Production Data

# B-19 annual production data access:
# Navigate to: https://www.aogc.state.ar.us/production.htm
# or: https://www.aogc.state.ar.us/onlineservices.htm

# Production data fields:
# - API Number
# - Well Name and Number
# - Operator
# - County
# - Formation
# - Annual Oil (BBL)
# - Annual Gas (MCF)

Cross-Reference Workflow for Li/Mg Research

# The most effective workflow for Arkansas Smackover lithium research:

# Step 1: Get Smackover well locations from AOGC
# Browse AOGC well data or GIS maps for south AR Smackover wells
# Key counties: Columbia, Union, Lafayette, Miller, Hempstead, Nevada, Ouachita

# Step 2: Get brine chemistry from USGS
# Use the usgs-produced-waters skill to query the USGS Produced Waters
# Geochemical Database, filtering for:
#   STATE = "Arkansas"
#   FORMATION contains "Smackover"
# This returns Li, Mg, Ca, Na, Cl, TDS, pH, etc.

# Step 3: Get DLE project details from company filings
# Standard Lithium (NYSE: SLI) — SEC filings at:
curl -s "https://efts.sec.gov/LATEST/search-index?q=%22standard+lithium%22&dateRange=custom&startdt=2024-01-01&enddt=2025-12-31" \
  -H "Accept: application/json"

# Step 4: Get DOE research from NETL EDX
# Use the netl-edx skill to search for lithium extraction research

Workflow

Step 1 — Resolve Intent

User wants...	Best channel
Specific well details	AOGC Well Data page (browser)
Production by well/county	AOGC B-19 Production Reports
Well locations on map	AOGC GIS Maps
Smackover brine chemistry	USGS Produced Waters DB (cross-reference)
DLE project status	Company SEC filings and press releases
Research literature	USGS Pubs, DOE OSTI, NETL EDX
Regulatory orders (spacing, pooling)	AOGC Rules and Orders page

Step 2 — Fetch Data

Due to AOGC's limited API infrastructure:

1. For well/production data: Use browser access to AOGC or request data directly
2. For brine chemistry: Use the usgs-produced-waters skill
3. For DLE project details: Query SEC EDGAR or company websites
4. For research: Use pnge-literature (OpenAlex/CrossRef/USGS Pubs/OSTI) or netl-edx skills

Step 3 — Parse and Integrate

The key value of this skill is integrating data across multiple sources:

• AOGC provides well locations, operators, and production volumes
• USGS provides brine geochemistry (Li, Mg, TDS)
• Company filings provide DLE economics and project timelines
• Academic literature provides formation characterization

Step 4 — Produce Output

Format: Raw Data Table + Narrative

**Summary:** The south Arkansas Smackover trend contains the highest-concentration
lithium brines in the United States. Union County wells average 310 mg/L Li, peaking
at 477 mg/L — well above the 100-150 mg/L economic threshold for DLE. Three major
companies have announced projects: Standard Lithium (SWA Lithium, Lanxess partnership),
ExxonMobil (Magnolia project, targeting 2027 production), and Equinor (Smackover
leases). Brine chemistry data from USGS Produced Waters Geochemical DB; well
counts from AOGC records.

Caveats and Data Limitations

1. Very limited API/online data: The AOGC has the most limited online data infrastructure of any major lithium-relevant state. There is no REST API, and even web-based queries are limited compared to TX, NM, ND, or LA.
2. 403 blocks on automated access: The AOGC website returns 403 errors for many automated requests, preventing programmatic data gathering.
3. Annual production only: Arkansas production reporting (B-19) is annual, not monthly. This limits time-series analysis granularity.
4. No brine chemistry in AOGC data: The AOGC does not track brine geochemistry. For Li/Mg/TDS data, the USGS Produced Waters Geochemical Database is essential.
5. Small conventional O&G base: Arkansas is a minor oil and gas state by volume. Its significance is almost entirely due to the Smackover lithium brine opportunity.
6. Brine production vs. O&G production: Some Smackover brine production in Arkansas is permitted as mineral extraction (for bromine by Albemarle/ Lanxess) rather than oil and gas production. These wells may not appear in standard AOGC oil and gas databases.
7. Rapidly evolving landscape: The Arkansas Smackover lithium space is changing fast (2024-2026). Company projects, lease positions, and regulatory frameworks are in flux. Cross-reference with recent company filings for current status.
8. Data request option: For comprehensive well and production data, the AOGC accepts direct data requests. Contact: [email protected] or (501) 683-5814.
