Why Ownership Structure Data Matters

Understanding ownership is crucial to grasp how companies are connected and managed worldwide. Our corporate hierarchy data allows you to follow the links between parent companies, subsidiaries, and shareholders, exposing control, structure, and risk within any global network. Whether you are studying Schlumberger or another worldwide business, this insight supports compliance checks, market analysis, and better CRM data management. With verified ownership records covering over 380 million companies around the globe, CompanyData.com offers a clear picture of corporate ownership across industries and borders.

Mapping Schlumberger’s Global, National, and Local Headquarters

At CompanyData.com, we organize company profiles – like Schlumberger – using a three-tier hierarchy system: Global, National, and Local headquarters. This helps reveal how each subsidiary fits within the larger corporate family.

Our three-level hierarchy explained

  • Global Headquarters — Schlumberger Limited is the global parent located in Houston, USA. This entity has ultimate control over the entire group.
  • National Headquarters — These entities manage the company’s operations within countries and report directly to the global parent. Examples include Schlumberger USA, Schlumberger Canada (Canada), Schlumberger France (France), and Schlumberger Netherlands (Netherlands).
  • Local Headquarters — These are regional offices or subsidiaries that manage local operations, projects, and compliance within specific areas.

Each company entity receives a unique ID so you can easily link subsidiaries to their parent companies, track ownership chains, and integrate this data into your own systems.

Control within the group

Control is defined by ownership stakes. If one company owns over fifty percent of another, it is marked as a controlled subsidiary. Our data highlights these majority-owned connections to display the group’s true structure clearly. This provides a transparent view of complex networks such as Schlumberger’s and can be applied to any multinational company.

Importance of this data

This structure helps identify key decision-makers within the Schlumberger group, simplifies regulatory compliance, and assists in merger & acquisition or risk evaluations. By using verified ownership information from CompanyData.com, users gain a confident understanding of Schlumberger’s corporate setup. Covering over 1,263 subsidiaries in more than 90 countries, our platform brings transparency and clarity to global corporate networks.
