What is Emergency Response?

The actions taken in the initial minutes of an emergency are

critical. A prompt warning to employees to evacuate or

shelter can save lives. A call for help to emergency

services that provides full and accurate information will help

the dispatcher send the right responders and equipment.

Action by employees with knowledge of well data and

process systems can help control a leak/blowout and

minimize damage to the facility and the environment.

Why Emergency Response is so Critical in E&P Sector?

� All the activities of E&P are vulnerable to hazards.

� E&P activities are highly capital intensive.

� Incidents in E&P Sector can cause drastic damage to the people and

environment.

� E&P activities are political and media sensitive and can cause irrevocable

damage to the Company.

� In spite of lot of technological development, incident level in E&P Sector not

coming down.

Precautionary Measures

� The key operational personnel should have very good knowledge of well

control procedures and equipment. It should be ensured that they are having

valid IWCF/IADC certificate.

� Proper use of trip tank and trip sheet should be done religiously and proper

monitoring of well volume should be done during pulling out/run in the hole.

� Round the clock 24x7 supervision and monitoring of operation by competent

person should be ensured during work over operation.

� Regular BOP drills should be done for all scenarios.

� Well to be observed for any activity before pulling out of Bottom Hole Assembly

� Function test and pressure test of BOP and other Well control equipment

should be done as per OISD-174.

� Pipe ram and Blind ram are not meant to be closed on Drill Collars.
