Description

IOGP Report 553

This report assesses the level of environmental exposure to the chemical products used in the exploration and production of hydrocarbons using high-volume hydraulic fracturing – such as shale gas. It was developed jointly by the International Association of Oil & Gas Producers (IOGP), the European Oilfield Specialty Chemicals Association (EOSCA) and the European Chemical Industry Council (CEFIC).

The report is in two parts:

  1. A SpERCs (Specific Environmental Release Categories) factsheet contains the relevant data. It includes detailed information on the emission factors and operating conditions for the use of a substance in high-volume hydraulic fracturing.
  2. A background document adds further information about hydraulic fracturing operations and the use of chemicals. It describes the main phases of a hydraulic fracturing operation with a detailed analysis of the operating conditions. This includes a section devoted to the use of different types of fracturing fluid.

The report covers environmental emissions during the exploration and production of hydrocarbons (such as shale gas) using high-volume hydraulic fracturing. This includes the handling of fracturing fluid products and proppants during hydraulic fracturing operations from the arrival of the substances on site to the end of well clean up when production starts. It does not cover the use of chemicals in exploration and production activities other than high-volume hydraulic fracturing nor site preparation and well abandonment. It is assumed that all of these activities are likely to take place at an onshore exploration and production site which will be developed according to stringent standards in order to minimize emissions to air, water and soil.
