5.2 SIMOPS Procedures The following lists minimum recommended procedures for specific operations.

5.2.1 Major Rig Movement

Major rig movement includes spotting/pulling legs or anchors, jacking up/down, submersing/raising barges, assembling/disassembling structure type rigs, cantilevering derrick, and transferring tender rig derrick from barge/semi onto platform or from platform onto barge/semi. These will require total Platform Shut-in as follows:

• Shut in wells at subsurface safety valve (SSSV). Bleed off tubing pressure. Perform SSSV leakage test. If SSSV leaks, install tubing plug or backpressure valve (BPV).

• Close wellhead surface safety valves (SSV).

• Shut in and bleed off flowlines and gas lift lines.

• Eliminate casing pressure.

• Bleed off gas lift casing pressure. Check casing pressure to ensure that gas lift valves (GLV) do not leak. Install pump through tubing plug below bottom GLV, if necessary.

• Shut in process piping and equipment.

• Shut in incoming, departing and crossing pipelines.





5.2.2 Heavy Equipment Movement

Heavy equipment movement which may endanger any in-service production equipment, (such as, skidding jack-up derrick, skidding production platform-supported derrick, rig up/down of snubbing unit, driving conductor casing, nippling up/down of BOP's, or wellhead, heavy crane lifts, etc) will require partial platform shut-in as follows:

• Shut in wells in the immediate vicinity of the activity at SSSV. Bleed off tubing pressure, perform SSSV leakage test.

• Shut in SSV's.

• Eliminate casing pressure.

• Shut in and depressurize flowlines and any additional unprotected process equipment in the immediate vicinity of the work.

• Shut in unprotected pipeline risers that may be endangered by loss of control of crane load.

5.2.3 Major Construction Operation

Any construction or repair activity that might impact the ongoing operations will require the following actions:

• Welding or burning outside safe welding area would require partial platform shut-in.

• Prolonged interruption of a component function in the process would require either partial or total shut-in.

• Movement of material would require partial shut-in.

• Activity that materially alters original structure plan would require either partial or total shut-in.

5.2.4 Wireline Operations

Wireline operations including any activity involving the use of electric line units, braided line units, or slickline units in the servicing, or workover of wells will require the following shutdowns:

• The drilling rig will be required to shut down during wireline work on adjacent wells unless permission is received from the supervisor on location and the Project Manager.

• Rig wireline work involving perforating will require a partial production shut-in.

• Rig perforating with tubing conveyed gun requires a partial shut-in and monitoring until gun is below the mud line.

• Perforating operations may require radio silence as required for the particular guns in use.

5.2.5 Concentric Tubing Operations

Concentric tubing operations including any activity involving the use of coil tubing units, snubbing units, or small diameter tubing units in the servicing or workover of wells by through tubing methods while the christmas tree is installed on the wellhead will require the following:

• An ESD system located in the immediate vicinity of the concentric tubing unit's controls. The ESD system will be tested to insure operation prior to commencing concentric tubing operations and at least once a week. All such tests will be recorded in the log of daily activities.





5.2.6 Drilling Operations

Any activity involving the use of drilling rigs, workover rigs, or hydraulic rigs in the drilling, completing, or servicing of wells, where blowout preventers are considered the primary control element in the surface control of the well, require the following:

• During installation of the blowout preventer assembly on the wellhead, all adjacent wells that might be damaged will be shut-in. All hydrocarbon handling lines in the immediate vicinity that might be damaged will be bled to atmospheric pressure.

• The movement of heavy loads over wellheads and hydrocarbon handling lines will be prohibited unless all such wellheads and hydrocarbon handling lines which might be damaged by loss of control of the load are protected. Protected as defined here means that wellheads are shut-in at the bottom master valve and all hydrocarbon lines that might be damaged are bled to atmospheric pressure.

• An ESD system will be located in the immediate vicinity of the control console of the unit being used for the drilling operations. The ESD system will be function tested to insure operation prior to commencing drilling operations and at least once a week. All tests will be recorded in the log of daily activities.

5.2.7 Pumping Operations

Pumping operations, including any activity involving the pumping of material into a wellbore for stimulation or remedial work, requires the following actions:

• The flowline from the pumping unit to the well connection should be pressure tested to the highest anticipated pump pressure. A Fail Safe Valve (FSV) will be installed at a point closest to the wellhead.

• Appropriate high pressure shut-off valves and bleed valves should be installed as a part of the pump manifold to permit disconnecting the pump if needed.

• Handling of hydrocarbon materials on the surface will be done in a manner consistent with minimizing the possibility of the occurrence of undesirable events such as harm to personnel, the environment, or damage to the equipment.

5.3 General Requirements • Any work involving use of explosives, perforating charges, chemical cutters, etc. will require

production shut-in until such device is run in hole below mudline. Welding will be suspended until re-authorized by the person-in-charge.

• Wireline work of any type, electric line or slick line, will require very close supervision of all hotwork. Hotwork will be suspended prior to bleeding gas from lubricators. Hotwork will be suspended throughout swabbing operations.

• Performing simultaneous downhole operations on different wells (i.e. wireline while drilling, pumping operations while drilling, etc.) requires pre-planning and review/approval by the person-in-charge for continued simultaneous production and/or construction activities.

• Well testing operations involving flaring of formation fluids will require authorization by the person-in-charge for continued simultaneous production and/or construction.

• Continuous production operator(s) "on duty" coverage will be required during simultaneous operations.

• The ESD system and general alarm systems will be function-tested prior to beginning SIMOPS and weekly thereafter.





• Under no circumstances will welding, cutting, drilling, or other hot work be performed on

hydrocarbon lines or vessels unless the line or vessel is first taken out of service, isolated from hydrocarbon and pressure sources, depressurized, drained, flushed, and free of flammable vapors. The process of performing hot work on in-service hydrocarbon handling equipment is known as "hot tapping." Hot tapping requires strict safety procedures and must be approved by the local manager after safety review. Hot tapping shall not be performed during drilling or workover operations.

• Hot work is defined as any activity generating open flame, spark, static electricity, or latent heat which has potential to cause ignition of flammable gasses, flammable-combustible liquids or ordinary combustible solids. Ignition sources may include grinding, welding, torch cutting, open flame, non-intrinsically safe electrical tools or appliances, sand blasting, pneumatic power tools, hand tools (unless constructed of non-sparking metal), etc. All hot work will be planned, scheduled, and permitted. All persons involved in other simultaneous operations will be informed of planned hot work.

• When hot work is performed concurrently with SIMOPS, the fire pump, if installed, should be tested daily. If the facility has no fire water system, consideration should be given to installing a temporary, portable fire water system or extending fire water system from the rig to the platform. Recommended system capability should deliver at least 90 gpm and 75 psi at each of two discharge stations. Hose reel stations should be planned.

• ESD, and gas detection systems including their associated sensors and shut down devices and fire detection components shall remain in full and complete operational order during simultaneous operations. In the event that any component of these emergency systems malfunctions, simultaneous operations will be suspended until repairs are completed. Bypassing or locking out of any safety device or sensor on in-service equipment will require prior approval by the person-in-charge. Normal testing of safety devices will not be deferred due to simultaneous operations.

• Upwind portable LEL gas detection is to be performed prior to initiating and continuously during SIMOPS hotwork. Hotwork will not be initiated and will be suspended if readings exceed 0% LEL.

• Simultaneous hotwork will not be performed at upper elevations where sparks and slag can fall onto in-service production equipment (especially if that equipment utilizes natural gas for instrument supply) unless the equipment is shielded with a flame-proof material and protected against potential damage from falling objects which may break valves, gauges.

• A designated stand-by vessel will be in continuous immediate attendance of rig or platform during SIMOPS.

• Upon detection of formation influx (well kick) the platform emergency shut-down system will be activated and all hotwork will be suspended until normal rig operations are resumed.

• Wells not equipped with both an operational surface safety valve and subsurface safety valve will be shut-in prior to and throughout SIMOPS. Wells with subsurface safety valves not passing a leakage test will have pump through tubing plug installed.

• Wells with a history of sand production which may cause erosion of chokes, flowlines will remain shut-in throughout SIMOPS.

• When performing simultaneous operations on one side of a dual well, the other side will be shut-in at the sub-surface safety valve, tubing pressure bled off, and the master valve closed, or the string will be killed.






• Wells that have production casing pressure resulting from tubing-casing communication will be evaluated to locate the source of communication, a pump through tubing plug installed below the source, casing pressure bled off and monitored to confirm isolation of communication, and tubing pressure bled off. If the production casing pressure results from other sources, such as packer or casing leak, the option of performing well kill operations prior to SIMOPS must be evaluated. Similarly, in wells that have annular casing pressure in strings other than the production casing string, the well kill options must also be reviewed prior to SIMOPS.

• Local management approval will be required to produce H2S wells during SIMOPS.

5.4 Person-in-Charge • One individual is to be the "Designated Person-in-Charge" for each simultaneous operation.

This individual will be designated by the Project Manager with approval of the area Operations Manager and will be responsible for supervision of activities and to ensure safety of operations. He will be required to be continuously on-site during SIMOPS.

• The person-in charge is responsible for all the pre-planning, site visits, risk assessments required for the execution of the SIMOPS.

• The person-in-charge is responsible to coordinate activities between drilling, completion, construction, and production to ensure safety of simultaneous operations. He will have the on-site authority to suspend any operation that may pose risk to the safety of employees, the environment, equipment, and general public. The person-in-charge will be present, on site, during all simultaneous operations.

6. RESPONSIBILTIES

It is the responsibility of the Project Manager to ensure that this procedure is followed in the preparation of the Simultaneous Operations Manual

7. RECORDS

The Simultaneous Operations Manual will be the record of the completion of this procedure. The manual will form an appendix to the Project Bridging Document and be included in the Project Filing System.
