Operational Excellence and Performance System (OEPS)

Setting an expectation for competency, consistency, reliability, and credibility across Weatherford

A Commitment to Excellence

Weatherford developed the Operational Excellence and Performance System (OEPS) to support our customers in their operations throughout the globe while meeting the criteria outlined by international management system standards.

OEPS combines quality, health, safety, environment, security, reliability, and essential business requirements into one comprehensive, performance-driven management system. The system establishes core expectations to deliver consistent service to our customers while protecting all personnel, property, processes, and the environment.

OEPS demonstrates our commitment to quality in our operations and fosters a culture of workers who are empowered to act in the best interest of everyone involved.

Consistent Standards. Consistent Service Quality.

At Weatherford, we aim to differentiate ourselves through our service quality. We understand the importance of consistently delivering quality products and services to our customers. To attain this goal, we provide quality control at several levels:

  • Management review
  • Document, data, and records management
  • Audits
  • Engineering support, design, and service configuration
  • Identification, status, and traceability
  • Control of company and customer property, assets, and inventory
  • Testing, measuring, and detection equipment
  • Control of nonconforming service-related products, processes, and devices
  • Continual improvement through preventive and corrective actions
  • Industrial maintenance
  • Key performance indicators
  • Procurement and supplier quality
  • Management of change
  • Security

Every day brings an opportunity to showcase our commitment to excellence, and every day we strive to meet and exceed those expectations.

A Higher Standard

How OEPS Aligns with International Management System Standards

Weatherford maintains core operational requirements, as detailed within international and national management system standards:

  • ISO 9001 Quality Management System Standard
  • ISO 14001 Environmental Management System Standard
  • OHSAS 18001 Occupational Health & Safety Assessment Specification

OEPS comprises five levels of documentation critical to the effective planning and execution of our products and services.

Policy documents capture our foundational intent, ideals, and rules.

Standards documents demonstrate compliance to ISO 9001, ISO 14001, OHSAS 18001, API Q2, and other international management systems and detail our health, safety, and environmental (HSE) controls, including country-specific regulatory and legal requirements. Weatherford has two categories of HSE performance standards.

Product-line technical documents facilitate the effective planning, operation, risk mitigation, and control of our products and services. These documents clearly describe how to perform a specific task, such as operating a piece of equipment, manufacturing a part, or repairing a tool. Technical documents also cover support functions and customer- and site-specific requirements.

To help mitigate risk and bolster reliability, product-line technical documents are developed using a three-step process:

  1. Risk assessment: A detailed assessment of the technical instructions for quality, health, safety, and environmental risks; the consequences associated with the risks; and the controls to eliminate or minimize them.
  2. Technical work instruction: The creation of a step-by-step list of requirements, with special attention to the critical risks previously identified.
  3. Process map: An expansion of those steps that have been deemed critical to quality, health, safety, and the environment.

Records and evidence demonstrate compliance with OEPS standards, engineering specifications, customer-stated requirements, regulatory requirements, and other applicable requirements. These documents include informational guides, checklists, forms, audit and inspection results, data, and records.

The structure and documents above represent the minimum OEPS requirements. A global business unit, region, or product line may add additional documents to meet the requirements of a specific country, region, customer, or site.

A Flexible Approach

How We Integrate OEPS into Diverse Operations

OEPS is applied across all of our business units worldwide to meet or exceed all applicable standards, regulations, and legal requirements. It incorporates key performance indicators to drive accountability and is flexible enough to accommodate the unique needs and expectations of each customer.

We understand that a rigid set of guidelines does not suit the breadth of our organization or that of our customers. Rather than applying one standard to all operations, we have organized OEPS according to four central principles:


All Weatherford employees receive
appropriate training through our
learning management tools and must
achieve competence before going out
in the field. Competency means that
each worker understands his job, the
risks associated with performing it,
and the controls necessary to
eliminate or minimize risks to the
individuals, organizations, and
communities with which we work.




Consistent systems and processes
are imperative to the success of our
business. OEPS provides training and
documentation to assure that we
perform our services in a similar
fashion across all of our operating
locations. We also apply unified
standards and policies through
contract management, responsible
leadership, equipment performance
integrity, asset and inventory
management, process assurance,
change management, and regulatory



Reliable service quality results from
applying a proven methodology.
OEPS outlines procedures for product
and service realization, risk
management, supplier and
subcontractor relationships, service
execution, performance tracking, and
continual improvement.




OEPS establishes a series of
benchmarks that foster a culture of
healthy competition, both internally
and externally, as we work to provide
the best possible products and
services to our customers. Our
system includes expectations for
product and service performance,
operational experience, customer
satisfaction, problem resolution, audit
performance, supply-chain
performance, employee experience,
and continuous learning with the goal
of incident-free operations.
