1. Purpose The purpose of this document is to provide practical assessors with a handbook that explains the practical assessment procedure. This document should be used as a guidance document to assist practical assessors to conduct IWCF practical assessments to IWCF standards.

2.

Scope

This document applies to all IWCF accredited practical assessors.

3. Practical Assessor Respon sibi lit ies Only an IWCF accredited practical assessor can conduct practical assessments. The practical assessor must:      

be accredited at the centre location where the practical assessments are conducted. be competent in the operation and programming of the simulator. understand the content and procedure for carrying out IWCF practical assessments. conduct practical assessments in accordance with IWCF procedures. be able to perform the role of the Level 3 (Driller) and Level 4 (Supervisor) candidates when required. not coach, advise or help candidates in any way during the practical assessment.

4. The sim ulator The centre is responsible for ensuring the simulator has been approved for use by IWCF. The practical assessor must ensure the simulator is set up for use according to IWCF requirements.

The simu lator environment The simulator environment must meet the following requirements: 

 









The only people allowed in the simulator room during IWCF practical assessments are the candidates being assessed, the IWCF accredited assessor, any assessors undergoing training and an IWCF Auditor (if present). Only one practical assessment at a time can take place in any simulator room. During the kill phase of the practical assessment, the Level 3 candidate must operate the pump while the Level 4 candidate must operate the choke. When portable simulators are used, the pump control panel and the remote choke control panel must be-angled. This is so that the Level 3 candidate cannot see the remote choke panel and the Level 4 candidate cannot see the pump control panel. Panels/displays must be positioned so that the assessor can discreetly observe the activity of the Level 3 and Level 4 candidates. The assessor must be able to make adjustments to the simulator during the assessment without the candidates seeing what changes are being made such as initiating the problem during the kill. Therefore, the assessor must position the instructor station so that the candidates cannot see any changes he/she makes. The following notices must be displayed in the simulator room: a) Practical Assessment – Notice to Candidates b) Practical Assessment – Notice to Assessors

Practical Assessor Handbook Simulator exercises All exercises loaded on the simulator must meet IWCF requirements, which are outlined in the IWCF Well Design Rules. In summary these are: 





Exercise wells used for practical assessments must be different to those used for training and practice sessions. There must be at least three different exercise wells for each stack type to use during practical assessments. Each exercise well must meet the minimum design rules with respect to depths, configuration, formations and pressures.

5. Before the practi cal assessment Pre-assessment checks Before the start of a practical assessment the assessor must: 





check the candidate’s photographic identification and write the candidate’s name on the front page of the grading sheet in accordance with the identification provided. must confirm the candidate’s identification has been checked by completing the ‘Candidate’s ID checked’ box on the front page of the grading sheet. ensure the combination of candidates is one of the following:

a) One Level 3 candidate with one Level 4 candidate assessed as a pair b) One Level 3 candidate with the assessor acting as the Level 4 candidate c) One Level 4 candidate with the assessor acting as the Level 3 candidate The above combinations of candidates are the only acceptable combinations. Please note: it is not acceptable to assess two or more Level 3 candidates together or two or more Level 4 candidates together. Candidates being assessed together must be assessed on the same stack type.  



ensure the simulator environment is set up according to Section 4 of this handbook. load an appropriate exercise on the simulator according to the IWCF Well Design Rules ensuring that re-sit candidates get a different exercise to any they have already failed. ensure the simulator line-up is set up as follows: a) b) c) d) e)



ensure the simulator plotting has been set to record from the start of the exercise and that the parameters below are in different colours from one another on the plot. The minimum parameters to be recorded are: a) b) c) d) e) f)



The standpipe manifold is not correct for drilling The choke manifold is not correct for drilling The remote choke is half open The Blow Out Preventer (BOP) is not correctly lined-up for drilling Manifold and/or Annular pressures are too low.

The time on the x axis (horizontal axis) The formation pressure on the y axis (vertical axis) The Bottom Hole Pressure (BHP) on the y axis to the same scale as the formation pressure The drill pipe pressure on the y axis The casing pressure on the y axis to the same scale as the drill pipe pressure The pit gain or pit level.

ensure the following details are printed on the graph: a) b) c)

ensure the correct grading sheets below are ready and have been completed with the appropriate centre, candidate and assessor details for the practical assessments: a) Practical Assessment Grading Sheet – Surface BOP Operations b) Practical Assessment Grading Sheet – Subsea BOP Operations

Pre-assessment bri efing Before the start of a practical assessment the assessor must advise the candidates that:  

  

 

the assessment will be conducted under exam conditions. the assessor will not coach, advise or help them in anyway but he/she may instruct them on the operation of the simulator if they know what they want to do but cannot remember how to do it. For example, the candidate wants to reset the stroke counter but cannot find the stroke counter reset button. If this happens, the candidate must directly ask the assessor where the stroke counter reset button is and then the assessor can show them. they cannot ask the assessor what they should do next in the assessment. the assessor must not prompt them at all. the Practical Assessment is a role-play scenario and they will be playing the role of Driller (Level 3) or Supervisor (Level 4) as detailed in the form Practical Assessment – Notice to Candidates. they cannot bring written instructions of any kind into the simulator room. before the assessment begins the assessor and Level 4 candidate must agree how the Level 3 candidate will be given instructions during the assessment. Acceptable methods are: a) Verbal after the assessment has started b) Written down on paper after the assessment has started c) Written on a whiteboard/flipchart after the assessment has started d) Or a combination of the above.







the assessment must be conducted as a single non-stop exercise. If the assessment being conducted is for a Level 4 candidate only, the pre-drilling preparation stage must still be completed up to the time the Supervisor leaves the simulator room. Once the pre-drilling preparation has been completed, the assessor can load a snapshot with the well shut in and pressures stabilised. Before loading the new snapshot, a simulator plot/graph must be printed off showing the preparation stages, the exercise will then continue. The assessor may, however, choose to go through the drilling phase in which case there will only be one plot/graph. a problem will be given at some time during the kill but only one problem will be given per assessment. the simulator must run at normal speed (real time) until after the problem and can run at an accelerated speed from then on. The simulator must be returned to real speed at least 100 strokes before the gas reaches the BOP.

Permit ted m aterials During the assessment candidates may only use the following materials: 



Blank paper, pens, pencils, ruler and non-programmable calculator. Devices with internet capability are not allowed. The Level 4 candidate may be given a pre-kick data sheet completed with volumes and strokes for the exercise depth (equivalent to page one of the IWCF kill sheet) and a blank kill sheet for use when the well has been shut i n (equivalent to page two of the IWCF kill sheet), all kill/kick sheets must be approved by IWCF prior to use. In some cases, the pre-kick data sheet and the kill sheet will be the same document. For clarity, the only details that can be given on the pre-kick data sheet are: a) The current mud weight b) The shoe MD/TVD c) The well MD/TVD at the start of the exercise d) Leak-off test information/shoe fracture pressure or gradient/maximum mud weight/Maximum Allowable Annulus Surface Pressure (MAASP) - any or all e) String, open hole, annular, total well and surface line volumes and strokes for the depth at the start of the exercise

The Level 3 (driller) candidate may be given a drilling trend/log sheet. A well kill trend/log sheet may be provided for use during the kill phase. A whiteboard/flipchart and pens.

Note: It is not a requirement to provide all of the above.

6. The practi cal assessment proc edure This section details the running order of a practical assessment from start to end. The running order assumes it is a double assessment with a Level 3 (driller) candidate and a Level 4 (supervisor) candidate. Comments are made for single candidate assessments when applicable. Subsea elements are clearly shown as being such. Surface candidates do not have to meet the subsea elements. Each step must be scored on the appropriate grading sheet as it happens. The practical assessment procedure details the points that must be awarded for each step. Please refer to these grading notes throughout the assessment. Assessors have no flexibility to adjust the scoring. The Practical Assessment procedure starts on the next page.

Shut-in procedure should comply with industry best practise for the Hard or Soft shut-in procedure. The assessor must ask the Supervisor why they chose the shut-in method if the Supervisor does not give it as part of the instructions. Standard instructions are: Pick up to space out position. Shut down Rotary and pumps. Check for flow. If not flowing, call Supervisor. If flowing shut-in as per procedure then: Check well is secure and call Supervisor. It is not acceptable for the Driller to be given instructions which prevent him conducting a flow check or detecting a drilling break. For example: “When you detect a drilling break, drill a further ten feet”.

NOTES Notes

The Supervisor may help the Driller in running to bottom but must leave the drill floor when the Driller has tagged bottom. The Driller must now drill ahead with agreed drilling parameters of Weight on Bit, RPM and SPM.

If there is no L3 (Driller) candidate, the assessor can load a snapshot with the well shut in on approximately ten barrels of kick with the pressures stabilised. In this case, print out a plot/graph of the drill floor preparation stage before loading the new snapshot. This graph must be signed off in addition to the graph of the kill at the end of the assessment. This will be an extra graph as two snapshots will be used. If the assessor chooses to continue with the same snapshot and drill into the kick, then there is no need to print a graph off at this stage. The final end of assessment graph will be enough. (13) 5. Drilling break The Driller must recognise and respond correctly to a drilling break.

Take correct action 5 pts – If done as per Supervisors instructions. 2 pts – If any one failure to fulfil Supervisor’s instructions. 0 pts – If Driller makes more than one failure from Supervisor’s instructions.

The correct action will be to: Pick up. Stop rotating (optional for flow check). Space out. Turn pumps off. Flow check and call the Supervisor.

3

Rest flow alarms ‘Y/N Grading’ .

The assessor can tell the Driller to continue drilling rather than bringing the Supervisor to the drill floor.

First thing to be done once it is confirmed the well is shut in and flow has stopped. If BOP failure incident has been selected then Supervisor should be called, after closing another BOP and confirming flow has stopped. ‘Y/N Grading’.

AC-0018

Correct procedure is to pick up to space-out positon, stop rotation, turn the pumps off and recognise flow.

15 seconds One minute How we know the kick is to large Do we need to calculate ? Do the Supervisor need to calculate ? What action if to large ?

Version 1.0


The Driller fails if drilling is continued for one minute after the kick is taken OR the Driller shuts in with the pumps running OR the kick taken is too large to circulate out without fracturing the formation OR the well is not shut in. The Driller must call for the Supervisor immediately after the well has been shut in and it has been confirmed that the flow has stopped. The assessor should wait for a period of time before calling the Supervisor to the rig floor. This is to allow time to assess whether the Driller starts to record the build-up of shut in pressures.

5 pts – If Supervisor’s instructions are followed correctly. 3 pts – If bit kept at bottom. 2 pts – If pump stopped before pulling the string. 0 pts – If more than one failure to follow Supervisor’s instructions. 5 pts – If done correctly. 2 pts – If Driller hesitates or takes more than 15 seconds before taking proper action, after a positive flowcheck or shuts the well in but not following the proper method according to instructions i.e. does not open side outlet valve.

Correct procedure is to pick up to space-out positon, stop rotation, turn the pumps off and recognise flow.

15 seconds One minute How we know the kick is to large Do we need to calculate ? Do the Supervisor need to calculate ? What action if to large ?

Note: See possible failure scenarios in NOTES column.

Inform the supervisor.

First thing to be done once it is confirmed the well is shut in and flow has stopped. If BOP failure incident has been selected then Supervisor should be called, after closing another BOP and confirming flow has stopped. ‘Y/N Grading’.

Version 1.0

The Driller fails if drilling is continued for one minute after the kick is taken OR the Driller shuts in with the pumps running OR the kick taken is too large to circulate out without fracturing the formation OR the well is not shut in. The Driller must call for the Supervisor immediately after the well has been shut in and it has been confirmed that the flow has stopped. The assessor should wait for a period of time before calling the Supervisor to the rig floor. This is to allow time to assess whether the Driller starts to record the build-up of shut in pressures.

When the kill has been restarted after the problem has been resolved, the simulator speed can be increased to bring the gas to the surface more quickly. The Supervisor must have the kill under control and confirm this to the assessor before the speed is increased. The simulator must be returned to normal speed at least 100 strokes before the gas reaches the BOP. The assessor must inform the Supervisor that the simulator is running at normal speed.

When the kill has been restarted after the problem has been resolved, the simulator speed can be increased to bring the gas to the surface more quickly. The Supervisor must have the kill under control and confirm this to the assessor before the speed is increased. The simulator must be returned to normal speed at least 100 strokes before the gas reaches the BOP. The assessor must inform the Supervisor that the simulator is running at normal speed.

The assessor must sign the first page of the grading sheet when the final score has been added. The assessor has the ability to transfer the marks from the grading sheet to the appropriate section of FORUM.

Debrief the candidates When the assessment has finished and before the candidates leave the assessment room, the assessor must:  



give candidates their final score. discuss the assessment exercise with the candidates and use the grading sheet and graph to highlight their strengths and weaknesses. if they fail, give candidates their re-sit options, detailed in Section 7 and answer any questions from the candidates.

7. Re-sit opti ons for the practi cal assessment In order to pass the IWCF practical assessment, a candidate needs to achieve a minimum of 70%. If a candidate fails their first attempt at the practical assessment, then they can take one re-sit before they try the written examinations. If a candidate fails their second attempt, (first re-sit), of the practical assessment, they must try the written examinations and pass at least one component before they try a third and final attempt of the practical assessment. If the candidate fails their second attempt, (first re-sit), of the practical assessment and fails both written examinations, then they cannot progress any further and must re-register as a new candidate.

Please refer to Appendix 1 for further clarification on the re-sit criteria.

8. Completin g the paperwork Paperwork sent to IWCF The following practical assessment documentation must be uploaded to FORUM for each candidate:   

A colour copy of the plot/graph signed by candidates and the assessor. A copy of the appropriate practical assessment grading sheet. A copy of the kill sheet if it is an L4 (Supervisor) candidate.

Retention of candid ate records The following practical assessment documentation must be securely stored at the Primary Centre for the duration of the candidate’s certification:   

The original copy of the plot/graph signed by candidates and assessor. The original practical assessment grading sheet. The original L4 Supervisor kill sheet.

9. Grading sheets IWCF practical assessments must be scored using the current IWCF grading sheets for each step of the assessment. Scoring must be done as outlined in the guidance given in this document; assessors have no flexibility to adjust the scoring. The most up-to-date versions can be found on the IWCF website. Printed copies cannot be guaranteed as being current. It is the responsibility of the assessor to ensure they are using the correct grading sheet. The current grading sheets are:  

10. Assessor accreditation Assessors must maintain their accreditation with IWCF every two years by submitting a Practical Assessor and Instructor Application Form Renewal. The requirements of this are summarised as: 



Maintain a current IWCF Drilling Well Control Certificate at level 4 in the highest level programme that they intend to assess, (for example, surface BOP or combined surface and subsea BOP). The assessor must achieve at least 90% in each assessment. Submit evidence they have conducted four practical assessments at level four. Applicants for surface BOP assessor accreditation must submit copies of four surface BOP practical assessments on IWCF candidates. Applicants for combined surface and subsea assessor accreditation must submit four practical assessments of which a minimum of two must be subsea BOP practical assessments on IWCF candidates. Each of the four practical assessments must cover a different one of the four problems set in the IWCF Practical Assessment programme.

The evidence required for each practical assessment is as follows:   

A copy of the L4 grading sheet A copy of the signed plot/graph (colour) A copy of the L4 (Supervisors) completed kill sheet.

In addition to the assessment evidence above, the following must also be sent in with the application:   

The assessor ’s current Curriculum Vitae A copy of the assessor’s passport page which contains the photograph A current passport style photograph.

The Practical Assessor Application Form Renewal must be submitted within 90 days of the assessor’s certification/accreditation expiry date. If this is received after the 90 days, the assessor must submit a new application. Please allow 20 working days for IWCF to process the renewal. The expiry date of an assessor’s accreditation is governed by the date their IWCF certification expires.
