PROCESS HAZARD ANALYSIS (PHA) OF INSTALLATIONS IN THE CUERVITO AND FRONTERIZO BLOCKS.

CONTEXT OF THE PROJECT

The process hazard analysis (PHA), define its scope in the development of techniques for the identification, evaluation and categorization of the risks to which the personnel are exposed, the environmental environment, the installations and production, as well as the generation of recommendations to eliminate, minimize and/or control the risks identified to an acceptable level, and repositioning of the risk, for the implementation of the recommendations for the operation of the Installations in the Cuervito and Fronterizo Installations:

  • Gas Collection Station Cuervito 1.
  • Gas Collection Station Cuervito 1A
  • Gas Collection Station Pamorana 1A
  • Gas Collection Station Cuervito 2
  • Gas Collection Station Zacate 1
  • Gas Collection Station Topo 2
  • Gas Collection Station Fronterizo 1
  • Gas Collection Station Entronque Topo

OBJECTIVE

The process hazard analysis (PHA) through methodologies for identification of hazards in the Installations in the Cuervito and Fronterizo Blocks belonging to the Integral Production asset Bloque Norte 01, of PEMEX Exploración y Producción. This analysis covers the possible scenarios of risk during the operation and activities that are identified, thereby minimizing the occurrence of damages associated with failures in the systems and human factors, with the purpose of controlling and/or minimizing the consequences, that affect the Personnel, the Population, the Environment, the Production and/or Installations.

TECHNICAL CONTEXT

Based on the applicable regulations for doing a process hazard analysis (PHA), the multidisciplinary working group was formed for the identification of Hazards and ranking of risks, the scenarios were identified that are subject to the analysis of estimation of consequences through the specialized commercial software PHAST, and analysis of frequencies through the event trees methodology, this serving as a basis for the reranking of the risk, finally resulting in the establishment of a series of recommendations for risk management.

RESULTS OBTAINED

In order to establish an integral system for the management of risks a qualitative and quantitative quantification was done of the inherent and administered risks in the Installations in the Cuervito and Fronterizo Blocks with the objective of identifying and evaluating their impact on the receptors of risks of interest and establishing a series of recommendations intended to maintain and reduce to a tolerable level the risks present during the operation of the installations.
