What CLL does
CLL INGENIERIA S.A. is a privately held Argentine engineering and consulting firm founded in 1994 by Ing. Carlos Luis Legnazzi, operating exclusively in the oil and gas sector. The company delivers multidisciplinary engineering services spanning process, mechanical and piping, stress analysis, electrical, instrumentation and control, and civil disciplines for crude and gas treatment plants, compression stations, water injection facilities, battery stations, pipelines, fire protection systems, and electrical substations. Services are organized into three core offerings: Design and Project Development (conceptual, basic, and detail engineering), Technical Assistance (project evaluation, engineering audits, procurement activation and tracking), and Consulting (investment studies, feasibility studies, cost budgets, technical-economic analysis of bids, field surveys, and construction inspection). The firm holds ISO 9001:2015 certification (IRAM and IQNET, certified since April 2006) for its quality management system.
The business model is B2B professional services delivered through direct enterprise field-sales relationships under long-term framework contracts (Contratos Marco) with oil and gas operators. The stated annual engineering capacity is 60,000 hours/year across all disciplines, expandable to 80,000 hours/year, delivered by a team of 18 professionals with a stated target of 30. Clients include major Argentine and international oil and gas operators — YPF, Pan American Energy, Total Austral, Tecpetrol, Refinor, Apache, ENAP Sipetrol, Compañía General de Combustibles, OXY, and Sener — alongside adjacent industrial customers such as ABB and Juan F. Secco. Geographic delivery spans Argentina, Venezuela, Peru, Ecuador, and Bolivia. Revenue is generated under professional services contracts, with no public pricing disclosed.
