PT. Pacific Well Services (PWS) was originally a service company for upstream oil and gas activities. As time went on, PWS changed its function to become an oil and gas field management company. The current problem is that the data system in PWS is still not standardized and manual, resulting in difficulty in consolidation and information. Besides, along with the increasing number of business units at PWS, data management is getting higher.Many applications are used in data processing and management at PWS, but the information generated is not integrated with a container, so management requires various teams to summarize these results to assess company performance, portfolios, and other decisions. The purpose is to design an Enterprise Architecture (EA) system that can summarize and integrate data of various sources to meet company management needs. In building an EA design based on The Open Group Architecture Framework (TOGAF) with a system architecture design based on Service Oriented Architecture (SOA). The TOGAF framework is through (1) selection of the reference model, viewpoints, and tools; (2) creating a description of the current architecture (baseline architecture); (3) creating a description of the target architecture; (4) implementation of gap analysis; (5) determining the components of the roadmap proposal; (6) settlement of impacts across the architectural landscape; (7) formal stakeholder review; (8) finalize the architecture; and (9) making architectural definition documents. The research was conducted by interviewing the parties where the case studies were conducted, collecting data in the form of related documents such as technical documents, supply chain, administration, finance, legal, projects, portfolios, and other related documents. From this study can be concluded that (1) the resulting informatian system architecture will be used in PWS; (2) the solution implementation is proposed to be carried out in stages, starting with support activities and then the main activities to minimize risks that may harm the company’s business operations; (3) Application of Data Warehouse and Business Intelligence is a solution to facilitate PWS to report and analyze information for internal and external company needs.
