Sofregaz Supports Oil & Gas Expansion in Algeria

  • Project Name: HBR Development Project
  • Country: Algeria
  • Project Site Location: Northwest of Hassi Messaoud
  • Name of Client: PTTEP on behalf of the association PTTEP-SONATRACH-CNOOC
  • Project Type: Conceptual design and cost estimation
  • Completion Date: 2017

The Hassi Bir Rekaiz oil and gas field, located northwest of Hassi Messaoud in Algeria, is undergoing a significant development led by PTTEP in partnership with SONATRACH and CNOOC. This project follows new exploration findings that revealed the potential for increased production, prompting the need for an expanded development plan. The project is set to include more than 100 production wells, a Central Processing Facility (CPF), and export pipelines that will facilitate the transportation of oil and gas to existing infrastructure.

Sofregaz has been entrusted with providing a fast-track engineering study and cost estimation for 22 different production scenarios, ranging from natural depletion to advanced recovery methods like gas lift and water injection. As part of this study, Sofregaz is responsible for:

  • Conducting process simulations to evaluate each production scenario,
  • Developing Process Flow Diagrams (PFDs) for oil and gas recovery and processing,
  • Sizing equipment for both production and utility systems,
  • Cost estimation for both CAPEX and OPEX to ensure financial feasibility of the scenarios.
Extensive Field Development

The project encompasses the drilling of over 100 production wells, each of which will be connected to a gathering station. These wells will be complemented by injection wells to enhance oil recovery. The Central Processing Facility (CPF) will be the core infrastructure for processing both oil and gas, allowing for the separation, stabilization, and dehydration of hydrocarbons before they are exported via pipelines.

Pipeline Infrastructure

A crucial component of the development is the construction of export pipelines that will transport processed oil and gas to existing regional infrastructure. This ensures the efficient delivery of hydrocarbons from the Hassi Bir Rekaiz field to global markets. Sofregaz’s expertise in pipeline design ensures that the pipelines are built to handle multi-phase flow and the challenging environmental conditions of the Algerian desert.

Scenario-Based Development

Sofregaz has evaluated 22 production scenarios, which include various methods of enhancing oil and gas recovery. These scenarios cover natural depletion, gas lift, submerged pumps, and water injection, with combinations of recovery methods to maximize the field’s output. Each scenario has been carefully analyzed to balance technical feasibility with economic efficiency, ensuring that the chosen approach aligns with long-term profitability.
