Ensure the right people are involved in performing the risk assessment. Fill out the header information as required. Include the Management of Change (MOC) form number if the assessment is associated with MOC. List each task or the required change. Depending on the level of the assessment, assess a group of tasks together or assess each individual step of the task. From your understanding of the process and knowledge of current and future needs, identify the hazards and risks associated with the task as well as the short and long term consequences. (See the Hazard Checklist on the last page of this template). Identify the “target” of the hazard or risk. Review the Hazard Severity (I to IV), the Probability Rating (A to F) and the Risk Priority Code (RPC) based on the matrix below (1 to 3). Increase the Risk Priority Code if it is difficult to detect that an event is starting to occur and, upon detection, there is insufficient time to prevent the event from occurring. This is especially important for low probability but very high severity risks or hazards that would normally have an RPC of 3. List all the appropriate risk reduction measures – consider the Risk Reduction Hierarchy. Identify the person responsible for implementing the control. Repeat step 6 with the risk reduction measures in place and determine whether the residual risk is acceptable. Where possible, add Contingencies in the event the task cannot be performed as expected. Consider the associated risks on a separate line. If the RPC is 3 the task is acceptable, otherwise a waiver may be required, unless the target is people. If the task is still an RPC of “1” it cannot proceed without implementing further risk reductions. For Hazards associated with people, the RPC must be 3. Summarize the critical controls from the assessment (particularly those that require special preparations in order to implement) and identify the person responsible for implementing the control. Track the progress of these preparations.

RISK REDUCTION CONTROL MEASURE (MITIGATION PLAN) AND NAME OF PERSON RESPONSIBLE FOR IMPLEMENTATION (Identify controls to reduce severity and/or probability)
RPC
1. Tag no cement or soft cement at expected depth leads to cementing job repitition. 2. Tag no cement or soft cement at expected depth in kick off plug case causes failure to drill sidetrack. 3. Cement flash set causes pipe stuck.

2 1. Collect the latest data from customer: wellbore geometry, mud weight, drill pipe dimension, bottom hole temperature, and loss circulation - PIC: Yudhis. 2. Discuss cementing program with customer and get their approval - PIC: Yudhis. 3. Compare the cementing program with the latest data prior to cementing job, communicate to coman and personnel involved regarding job procedure - PIC: Yudhis, Jonathan.

Y 1. If pressure increases significantly during the job which indicates cement flash set, then it is reccomended to displace the line and pull out the drill pipe out of hole as soon as possible to avoid pipe stuck. 2. Take mixing fluid, cement, and blended cement from location which are used actually for the job to be investigated on lab and make recommendation for next job. - PIC: Hendra
Perform lab testing to determine slurry recipe.
1. Inaacurate lab test results lead to job failure. 2. Insufficient time to run the lab test causes the cementing program late to be delivered for job leads to NPT.

Pump cement slurry
1. ADC doesn't work causes cement density could be can't be maintained. 2. Difficult to pump the slurry due to too thick and can cause loss prime, or flash set happens. 3.

Ensure the right people are involved in performing the risk assessment. Fill out the header information as required. Include the Management of Change (MOC) form number if the assessment is associated with MOC. List each task or the required change. Depending on the level of the assessment, assess a group of tasks together or assess each individual step of the task. From your understanding of the process and knowledge of current and future needs, identify the hazards and risks associated with the task as well as the short and long term consequences. (See the Hazard Checklist on the last page of this template). Identify the “target” of the hazard or risk. Review the Hazard Severity (I to IV), the Probability Rating (A to F) and the Risk Priority Code (RPC) based on the matrix below (1 to 3). Increase the Risk Priority Code if it is difficult to detect that an event is starting to occur and, upon detection, there is insufficient time to prevent the event from occurring. This is especially important for low probability but very high severity risks or hazards that would normally have an RPC of 3. List all the appropriate risk reduction measures – consider the Risk Reduction Hierarchy. Identify the person responsible for implementing the control. Repeat step 6 with the risk reduction measures in place and determine whether the residual risk is acceptable. Where possible, add Contingencies in the event the task cannot be performed as expected. Consider the associated risks on a separate line. If the RPC is 3 the task is acceptable, otherwise a waiver may be required, unless the target is people. If the task is still an RPC of “1” it cannot proceed without implementing further risk reductions. For Hazards associated with people, the RPC must be 3. Summarize the critical controls from the assessment (particularly those that require special preparations in order to implement) and identify the person responsible for implementing the control. Track the progress of these preparations.

RPC
1. Tag no cement or soft cement at expected depth leads to cementing job repitition. 2. Tag no cement or soft cement at expected depth in kick off plug case causes failure to drill sidetrack. 3. Cement flash set causes pipe stuck.

Y 1. If pressure increases significantly during the job which indicates cement flash set, then it is reccomended to displace the line and pull out the drill pipe out of hole as soon as possible to avoid pipe stuck. 2. Take mixing fluid, cement, and blended cement from location which are used actually for the job to be investigated on lab and make recommendation for next job. - PIC: Hendra
Perform lab testing to determine slurry recipe.
1. Inaacurate lab test results lead to job failure. 2. Insufficient time to run the lab test causes the cementing program late to be delivered for job leads to NPT.

Pump cement slurry
1. ADC doesn't work causes cement density could be can't be maintained. 2. Difficult to pump the slurry due to too thick and can cause loss prime, or flash set happens. 3.
