HSE-POLICYSAFETY POLICY ONGC believes that no work or service or activity is so important or urgent

that safety be overlooked or compromised. Safety of the employees and public, protection of their as well as Corporation's assets shall be paramount. Corporation considers that safety is one of the important tools to enhance productivity and to reduce national losses.

HEALTH POLICY To provide a structured program to look after and promote the health of

vital "Human resource", essential for productivity and effectiveness of the corporation.

ENVIRONMENT The corporation is committed to conduct its operation in such a manner as

compatible with environment and economic development of the community. Its aim is to create an awareness and respect for the environment, stressing on every employee's involvement in environmental improvement by ensuring healthy operating practices, philosophy and training.

TERMS USED IN UPSTREAM OIL AND GAS INDUSTRY Gas Flaring: Strive towards ultimate elimination of hydrocarbon flaring.

Gas Venting: Eliminate continuous venting hydrocarbon disposal.

Halons: Zero losses of halons by gradual elimination/ replacement.

Resources: Optimize use of resources – land, energy and raw materials.

Discharge of waste/ produced water: Dispose the produce water and effluents

compatible with the environment in line with national regulatory standards and

international standards as well.

Drilling muds and cuttings: Not to use oil based muds except in emergency

requirement and dispose off drilling mud’s and contaminated cuttings in such a way as

not to release contaminants to the environment.

Contd..Solid Wastes: Control and minimize all other solid wastes and treat

and dispose as per international standards.

Oil and Chemical spills: Prevent oil and chemical spills and, if they

occur, clean them up in timely and environment friendly manner.

Causes of Accident

The various causes of accidents are:

Defect in Design

Defect in Construction

Defect in Material of Equipment

Faulty Operation or Maintenance

Lack of Monitoring

Major Activities of Upstream Oil and Gas Industry

Drilling Activities

Production Activities

Exploration Activities

Safety and Environment Management in Drilling Operations

Drilling operations are carried out to locate hydrocarbons (Exploratory

drilling) to delineate a discovered reserve, to develop a reservoir for

production, for water injection, for EOR and for disposal purposes.

Some serious accidents that occurred in the recent past in India and

abroad, emphasized the need for the industry to review the existing

state of art in designing, operating and maintaining oil and gas

installations.

Critical operations need to be focused for safe and healthy well completion

Prior to spudding of the well During drilling operations After drilling Before round trip During round trip Before lowering casing During lowering of casing Prior to DST operation After DST operating During logging During wire line operation During fishing During casing During production testing Preparation for cementation During cementation

Inland Spills

Safety and Environment Management in Exploration Activities

On Land Exploration activities in upstream of hydrocarbon industry

primarily involve Geophysical Survey, Logging, perforation reservoir

studies and allied operations.

Explosives

Geological Surveys

Generators

Shooting

Well Logging

USE OF EXPLOSIVES FOR WELL PERFORATION

HSE MANAGEMENT PRACTICES Commitment and Leadership –Demonstrate the desire for world-class

performance.

Roles, Responsibilities & Accountabilities- Make everyone aware of his/her personal obligations regarding safety and that he/she will be evaluated and held accountable.

Policy & Procedures- Document & proper filing of essential information, work requirements, preventive maintenance and safe operating procedures.

Behaviour Skills- Motivate, observe and reinforce individuals to use safe behaviours.

Training – Assess training needs and develop the knowledge, skills, attitudes and competencies for individuals to perform in a safe manner.

Contd.. Communications – Exchanging of information during meeting and

allowing two-way dialogue among individuals on HSE issues and performance.

Risk Management & Evaluation – Identify, access and manage hazards situations which may pose a risk to people or assets and provide control.

Performance Measurement & Assessment – Establish track measures to assess and improve progress towards safety excellence.

Audits – Use a systematic approach to evaluate compliance or not and to use the results to improve safety performance.

Incident Investigation – Utilized trained personnel to investigate each incident to determine the root cause, communicate the result and use the information to take corrective actions to prevent future accidents and determine the accident costs

 

RISK ASSESSMENT AND ANALYSIS Identification of all credible hazards or threats to operations, along with

a list of critical control measures and development of a risk register.

Layers of protection analysis and safety integrity levels.

Consequence assessments, in order to evaluate the impact of potential undesirable events including fire and explosion assessments, toxic gas dispersion and business interruption.

Likelihood estimation for potential events based on historical data and frequency modelling.

Risk assessments at different levels of detail (qualitative, semi-quantitative and quantitative).

Development of risk-based and cost -effective solutions and decision support together with customers.

Training in risk assessment approaches for representatives.

TECHNOLOGY TO ENHANCE FIRE AND LIFE SAFETY

Actively explore ways to identify and utilize the latest technology to push the education and code message.

Develop smoke alarm technology that serves needs of broad range of occupants, especially those at highest risk.

Establish a competition to encourage the development of new technologies.

Increase the number of residential occupancies, including modular and manufactured homes, using fire sprinklers.

Fully utilize technology for real time reporting of emergency response data.

Require inherently safer consumer commodities.

Contd.. Develop complete strategies for introducing new fire and burn

prevention technologies to consumers.

Develop technology to improve residential fire/emergency evacuation processes.

Support completion and adoption of integrated building design and construction.

Create a nationally standardized inspection reporting system by utilizing handheld technologies to support the fire inspection process.

Require inherently safer consumer commodities.

CONCLUSIONUpstream oil and gas operations involve a range of activities, including

exploration and drilling, conventional oil and gas production, extraction and processing of ‘tar sands’, heavy oil processing and pipeline operations.

Firstly, to outline the nature of health risks in the offshore oil and gas industry to date.

Secondly, to outline the commercial, technical and social challenges that could influence the future context of health management in the industry.

Thirdly, to speculate how the health function within the industry needs to respond to these challenges. The relative stability of the knowledge base regarding health hazards offshore may change as more innovative methods are employed to develop hydrocarbon resources in more ‘difficult’ environments. Society's willingness to accept risk is changing. Addressing potential health risks should be done much earlier in the planning process of major projects. This may reveal a skills gap in health professionals as a consequence of needing to employ more anticipatory tools, such as modeling exposure estimations and the skills and willingness to engage effectively with engineers and other HSSE professionals.
