®Hazard/Risk Evaluation

• HAZARD : a condition that exists with the potential to do harm or damage to personnel,property or equipment.

• RISK : the likelihood of the hazard causing harm or damage to personnel, property orequipment

• HAZARD CONSEQUENCE : relates to the possible impact of a particular hazard

arising, to either the safety of personnel/installation or to the success of the operation





®Hazard/Risk Evaluation

• FREQUENCY OF OCCURANCE: probability of a particular hazard occurring.

• Very unlikely RARE to occur during an operation.

• Possible SOMETIMES likely to occur during the operation.

• Very Likely ALMOST ALWAYS OCCURS during the operation.

• CONTROL MEASURES – safety or operational measures that are either already inplace or require to be investigated in order to mitigate the risk or reduce the level ofrisk to an acceptable level.

Once the control measures have been identified & implemented, the risk should then bereassessed to ensure a low assessment. There may still be some operational riskassociated with the task referred to as Residual Risk.

®Residual Risk

• Operational and HSE risks, must be reduced to as low as possible (ALARP)*

(ALARP)* - The code of “ As low as reasonably practicable” dictates that even if the risk can

be shown to be tolerable, it must be reduced until the cost of further improvement becomesgrossly disproportionate to the risk reduction achieved. This may still result in the residual riskbeing defined as medium or high as described.





®Category of Residual Risk

• LOW Adequate measures are in place

• MEDIUM (safety) Do not proceed. Identify further control measures or an alternative

method of executing the operation such that the residual risk is reduced to LOW.

• MEDIUM (operational) Do not proceed until all additional control measures have beenidentified & implemented such that the residual risk is reduced to LOW.

• HIGH (safety) Do not proceed. Identify further control measures or an alternative methodof executing the operation such as the residual risk is reduced to LOW.

• HIGH (operational) If it is decided that the residual risk remains high followingimplementation of all control measures, the operation may continue.

– Effective Site Specific HSE Plan

– Audits, Inspections

®Equipment Design

• A properly designed andimplemented UBD QHSEsystem is safer than

conventional drilling system

• A properly designed UBDsystem does not have todepend on personnel

properly interpreting andresponding to well controlincident

• The system is designed toproperly handle & process

flow from the well





®

HAZOPs and HAZIDs are both systematicprocesses to Identify Hazards

• A HAZOP is designed to review process systems and operating proceduresto confirm whether they will operate as intended, without having introducedany avoidable hazards.

• A HAZID is designed to identify all potential hazards which could result fromoperation of a facility or from carrying out an activity.

• A HAZID is based on the HAZOP process but is more flexible.

®HAZOPS, HAZIDS & SIMOPS

• What are they & why do them?

• HAZOPs and HAZIDs are both systematic processes to identify hazards.

• “You cannot manage what you don’t know.” – A HAZOP is designed to review process systems and operating

procedures to confirm whether they will operate and be operable asintended, without having introduced any avoidable hazards.

– A HAZID is designed to identify all potential hazards which could resultfrom operation of a facility or from carrying out an activity.

– A HAZID is based on the HAZOP process but is more flexible.





®HAZOPS & HAZIDS

• A group of experienced people are led through a systematic process as a means ofcarrying out a detailed review of a system or activity.

– The system or activity is broken down into simple sections (Nodes) and, byapplying a set of guidewords, the team identify potential hazards, safeguards

in place and any shortcomings.

• A summary of the overall project/facility and the design intent from the project or processengineer .

• Description on how the scope has been divided and provide a list of nodes.

• Run through the guideword list highlighting any proposed variation to normal practice.

• The node is described and marked on the drawings provided

®HAZOPS & HAZIDS

• Review of P&IDs and cause and effects at:

approved for manufacture

revision after inter-discipline checks

and before manufacture starts

• For vendor equipment – once the drawings are available

• In the final stages of preparing a procedure

• Management of change





®HAZOPS & HAZIDS

HAZIDS – Example – UBD Project

• Usage of crude as drilling fluid• Compressed gas in the drill string and surface pipe work

• Intentional loss of primary well control barriers (i.e. mud column)

• H2S

• CO2





®Hazards Associated with UBD

• Positive Surface Pressure (Live Well Risk)

Reliance on mechanical barriers

High Fluid Return VelocitiesSurface equipment erosion

Down hole fire/corrosionLive Formation Fluids at Surface

Fire—H2S

Wellbore Stability Problems

Hole collapse, mud weight required for support

®Operational Procedures

UBD PROCEDURES (HAZOPED)

• Procedures on all critical operations are documented and HAZOPed

• No deviation to procedures is tolerated in UBD

• Management of change process is frequently used to facilitate anyproposed changes to procedures or systems at site

• Management of change form to be used for permanent changes





®Training

• All personnel from the Package Supervisor or Engineer down to Assistant

Operators are fully trained in the operation of all items of UBS equipment

deployed for the projects.

• Where training or advance courses are required our own staff as well as the

operators can benefit from participation.

• UBD Well Control Simulator is installed in the Regional Office

• Communication is the most important for UB solutions and full radio sets are

utilized.
