Houston and Greater Houston account for 406 contacts, while Midland and Midland-Odessa account for another 143 contacts.

The United States location associated with 43 contacts is a broad geographic designation rather than a city and may represent an opportunity for additional contact enrichment.

5. Status by Count

Status	Records	% of Total
Unchanged	803	70.4%
Update	310	27.2%
New	28	2.5%

Approximately 30% of the contact database has been created or modified within the most recent 30-day period.

The 310 Updated contacts are particularly useful for sales intelligence because recent profile changes can indicate changes in title, employer, responsibilities or other contact information that may create a reason for outreach.

6. Executive Summary

The report contains 1,141 contacts focused on the drilling organizations of U.S. oil & gas operators, with Drilling Engineers representing approximately 87% of all records.

The database is concentrated among large, active operators including Chevron, OXY, ConocoPhillips, BPX, ExxonMobil and EOG Resources. This provides meaningful contact depth within individual accounts and allows OFS sales teams to pursue an account-based selling strategy rather than relying on a single contact at each operator.

Geographically, the strongest concentrations are Houston and the Permian Basin, particularly Midland. Houston represents corporate, engineering and technical decision-making, while Midland provides access to personnel closer to field execution and Permian drilling programs.

For sales and lead generation, the strongest value comes from combining:

Operator Classification + Role + Job Title + Status + Geography

For example:

Steady State + Drilling Engineer + Sr/Lead/Manager + New or Updated

This creates a more focused list of contacts associated with active drilling programs and higher levels of technical or organizational influence.

7. OGL Operator Classification Methodology

The OGL Operator Classification Methodology groups oil & gas operator accounts based on drilling behavior, including rig activity, wells drilled and recent permit activity.

A well permit with a status of New represents a well that has been approved but has not yet been spud or drilled. Once drilling begins, the permit status changes to reflect that activity.

The objective of the classification methodology is to help sales teams distinguish between operators with continuous drilling programs, intermittent activity and historical or dormant development activity.

Operator Classification Breakdown

Operator Classification	Records	% of Total
Steady State	1,005	88.1%
Dormant / Legacy	95	8.3%
Next Tier	41	3.6%

Steady State

Definition: Operators that continuously drill within a play or geographic area regardless of commodity-price fluctuations. These operators typically generate the greatest recurring opportunities for companies supporting new drilling and associated facility infrastructure.

Criteria:

The account has a value in the Rig Count field.
Wells Drilled 2026 is equal to or greater than the number of months year-to-date.

Sales implication: Steady State operators should generally represent the highest-priority drilling accounts because their continuous development programs create recurring demand for drilling contractors, equipment, technology, consumables and field services.

Next Tier

Definition: Operators that have demonstrated drilling activity within the designated period but are not drilling at the same frequency or consistency as Steady State operators. Activity may include new development wells or infill drilling.

Criteria:

The account may have a value in Rig Count, but Wells Drilled 2026 is less than the number of months year-to-date.

The account may have no active rig count, but Wells Drilled 2026 is equal to or greater than 1.

Sales implication: Next Tier accounts are important growth and monitoring opportunities. New well permits, additional rigs, asset acquisitions or increasing drilling activity can signal that an operator is moving toward a larger development program.

Dormant / Legacy

Definition: Operators that have received approved well permits during the current year or previous two years but have not demonstrated current-year drilling activity.

Criteria:

Rig Count is less than 1.
Wells Drilled 2026 is less than 1.

Sales implication: Dormant / Legacy accounts normally represent a lower immediate priority for new drilling services. However, new permits, rig additions, acquisitions or other development signals can quickly move these accounts back into an active sales opportunity.

Why the Classification Matters

The OGL classification system allows sales teams to prioritize operators based on actual drilling behavior rather than company size alone.

Steady State: Core recurring drilling market
Next Tier: Emerging or intermittent drilling opportunity
Dormant / Legacy: Monitor for reactivation

This provides a practical framework for determining who to call now, who to develop and who to monitor.

8. Business Function Represented in the Report

The report represents the drilling function within upstream oil & gas operators.

Drilling organizations are responsible for planning, engineering and executing the construction of oil and gas wells. Depending on company structure, these teams may be responsible for:

Well design and drilling programs
Rig and contractor coordination
Directional drilling
Drilling fluids
Bits and bottom-hole assemblies
Casing and cementing
Well-control planning
Drilling optimization
Cost control
Non-productive-time reduction
Drilling performance and reliability

These contacts are therefore highly relevant to suppliers involved in the well-construction value chain, including drilling contractors, directional drilling, MWD/LWD, drilling fluids, drill bits, downhole tools, tubulars, cementing, rental equipment, automation, software and drilling-performance technologies.

9. Role of a Drilling Engineer Within a U.S. Oil & Gas Operator

A Drilling Engineer is responsible for designing, planning, optimizing and supporting the safe and economical construction of oil and gas wells.

The Drilling Engineer translates geological and reservoir-development objectives into an executable drilling program and works closely with drilling contractors, field operations and service companies.

Typical responsibilities include:

Preparing well designs and drilling programs
Selecting drilling technologies and systems
Developing drilling cost estimates
Evaluating drilling performance
Coordinating service providers
Reducing non-productive time
Improving drilling efficiency
Managing technical risks
Evaluating new technologies
Supporting field execution

Senior, Lead and Staff Drilling Engineers can also have significant influence over technical specifications, product trials, service-provider recommendations and technology adoption, even when final commercial approval resides with management or procurement.

10. How to Sell to a Drilling Engineer

Drilling Engineers generally respond more effectively to a technical and operational value proposition than to a broad corporate sales message.

The conversation should focus on measurable drilling outcomes such as:

Reduce non-productive time
Increase rate of penetration
Reduce drilling days
Lower cost per foot
Improve tool reliability
Reduce unnecessary trips
Improve directional accuracy
Improve wellbore quality
Reduce operational risk
Simplify field execution

A useful sales framework is:

Operational Problem → Technical Solution → Measurable Impact → Field Evidence

For example:

“We helped a comparable Permian drilling program reduce drilling time by improving tool reliability and eliminating unnecessary trips.”

Salespeople should avoid beginning with a generic company introduction. Instead, use information about the operator’s basin, drilling activity, rigs, recent permits and likely technical challenges to make the outreach relevant.

Recommended Targeting Strategy

For this contact database, prioritize contacts using the following sequence:

1. Steady State Operators
Target operators with continuous drilling programs first.

2. Next Tier Operators Showing Increasing Activity
Look for new permits, additional wells or new rig activity.

3. Senior Technical Contacts
Prioritize Sr, Lead, Staff, Manager, Supervisor, Superintendent, Director and VP-level personnel.

4. New and Updated Contacts
Recent contact changes provide a natural reason to research the person and determine whether their responsibilities have changed.

5. Match the Sales Message to the Operator’s Current Drilling Program
Use drilling activity, basin and operator classification to position the product or service around an identifiable operational need.

The objective is to move from simply providing a contact list to identifying the right operator, the right drilling contact and the right reason to engage now.
