Attachments: removed.txt; 04232015 Revised MCU A ppendix A - OM Plan.docx

As we discussed during our call on April 9, I have revised the introduction of the O&M Plan to explain why the Acid Gas

compressors aren’t listed in the Life Cycle Maintenance Plan. The short explanation is that they weren’t included

because the Acid Gas A is permanently out of service and the Acid Gas B is so small that it isn’t considered part of the

primary process train at the facility. The Acid Gas compressors weren’t in the Consent Decree plan either.

### I. Process Overview and Operating Procedures

The McElmo Creek Compression Plant serves tertiary recovery operations for the

McElmo Creek Field. The Plant receives produced gas through a gathering system,

pressures the gas up to a suitable working pressure then re

- injects the gas to maintain

reservoir pressure. The natural gas is injected with produced water in a dual injection

system. Due to varying water injection demands in the field, and to the number of wells

being serviced at any time, the Plant inlet volume can vary between 10 and 24 million

standard cubic feet per day ( MSCFD ).

The gas is processed in three main steps: inlet separation, compression and re

injection.

Inlet Separation : The inlet separation consists of an inlet slug receiver which collects

free liquids. The gas then passes through filter vessels which collect any incoming

solids.

Compression : The Plant houses four high

- speed electrically

- driven reciprocating

compressors , HOS

- 6, HOS

- 4, C

- 5 and Acid Gas B . HOS

- 6, HOS

- 4 and C

- 5 are the primary

facility compressors. The Acid Gas A compressor is a smaller unit and is only used for

backup and excess throughput. The compressors provide appr oximately 8

, 0 00 combined

b rake h orsepower (BHP) and e ach compressor consists of four or five compression

stages which raise the pressure of the incoming gas from 40 psig to 2

, 900 psig. Each

stage has a dedicated aerial cooler and liquid scrubber vessel. Inter stage dehydration

takes place to remove water for corrosion mitigation on the HOS 6 Unit. A fifth

compressor, Acid Gas A, is also present at the plant, but is non

- functioning and

uneconomical to return to service. It remains at the plant as a source of spare parts for

the Acid Gas B compressor.

Isolation and operating procedures for the Acid Gas B and HOS 4

, HOS 6 and Ariel C

- 5

compressors are included in the appendix to this report.

Re

- Injection : The four compressor units discharge into a single header, where

purchased C02 is co

- mingled to achieve a daily injection rate of up to 24 MSCFD. The

gas is then distributed to the field.

During Plant upsets or compressor downtime events, a portion or all of the inlet volume

to the Plant is automatically diverted to flare until the problem is corrected.

II. Routine Monitoring / Surveillance

The plant is manned 24 hours a day by operators who work 12

- hour shifts. The

operators make plant rounds each shift, during which key operating parameters of the

compressors and supporting equipment are monitored. The following are examples of

the parameters that are recorded during a shift:

### • Overall Plant inlet and discharge volumes

• C O 2 purchased volumes

• Flared volumes

• Discharge pressure

• Compressor run times

From the Operator's daily run time report (example attached in appendix to this report), a

compressor reliability spreadsheet and flare volume report are updated.

The Operators monitor key operating parameters for the compressors to ensure the units

are operating within prescribed operating limits based on Resolute Natural Resources

Company, LLC and original equipment manufacturer (OEM) standards. Examples of

parameters that the Operators record includes :

• Compressor suction and discharge temperatures and pressures

• Scrubber liquid levels

The detailed parameters that are checked during the shift are included in the maintenance

plan and operating procedures included in the appendix to this report. The operators are

very familiar with prescribed operating limits, as this is part of their training. If the

operator observe s a parameter that is out of specification, appropriate corrective action is

performed

.

III. Maintenance Plan

Resolute Natural Resources Company, LLC utilizes a Rotating Equipment Engineer to

assess ongoing reliability improvements, including oversight of the following items :

• Periodic maintenance that will be performed on the equipment.

• Predictive maintenance that is to be done on the equipment.

• Equipment life cycle

• Overhaul schedule

• Spare parts inventory

The appendix to this report contains specific tasks that comprise the Life Cycle

Maintenance Plan for the HOS

- 6, HOS

- 4 and C

- 5 compressors. The process includes

Periodic Maintenance, Predictive Maintenance

, Equipment Life Cycle and Overhaul

Schedule s which describes the various levels of maintenance for the primary plant

compressors. The Acid Gas A compressor is included in the m aintenance p lan, but is not

addressed in this a ppendix because it is only capable of handling 1.6 MMCF/day and was

never intended to be part of the primary process train at the facility.

### A. Periodic Maintenance ( PM's)

Periodic maintenance begins with daily inspections of the compressors, which are

performed by the Plant Operator and i n addition to monitoring process parameters and

plant mechanics the following daily equipment checks are made:

• The compressor piping, inter stage coolers and block valves and compression

valves are inspected for fluid leaks

• Oil and water levels are monitored

• Vibration levels on the motors and compressor frames are monitored

• General observations of physical conditions (i.e., unusual sounds) of the

compressor and electric motor are noted.

Additional periodic maintenance includes:

• Compressor performance analysis (Beta)

• Lube oil analysis data to determine the condition of the electric motor,

compressor and all of the auxiliary equipment.

• Foundations and equipment mounts are checked for cracks and correct

make

- up torque.

• Co mpressor Piping is inspected for external damage

• Corrosion coupons are pulled and monitored

Annual Inspections involve performing functional tests on the instrument and controls

systems. This includes testing safety devices, vibration probes, safety alarms and safety

shutdowns. There are PM's frequencies that extend past a year, such as coolant

replacement and lube oil replacement. The Rotating Equipment Engineer decide s if this

work is required.

B. Predictive Maintenance

The Rotating Equipment Engineer assesses p redictive maintenance which involves

performing detailed inspections for internal wear. The inspections reveal the remaining life

of a compressor component. Some examples of the predictive maintenance include

inspecting the compressor main bearings, compressor cylinder and piston inspection s

, electric motor winding/ insulation inspection , crankshaft web deflections and electric motor

bearing inspection.

The results of predictive maintenance inspections are recorded, trended and used to

determine when the next major maintenance is due.

### C. Equipment Life Cycle and Overhaul Schedule

The Rotating Equipment Engineer determines the life cycle for the compressors. This life

cycle information and the data taken during the predictive maintenance is used to

determine when the electric motor and compressor should be overhauled. An overhaul

involves opening up the machine and replacing all worn parts with new or refurbished

parts. Overhauls can take up to one month or more to complete. The compressor is

restored as much as possible and another life cycle begins. The common practice is to

hire additional contract mechanics to perform this work. Overhauls are recorded and all

of the data and measurements kept on file. These files are kept on site and with the

contractor that performed the work.

D. Life Cycle Maintenance Model

The section below provides a description of the type of activities planned for each level

of predictive maintenance

. Note Levels 5 and 6 are subject to the Risk Based Work

Selection process prior to committing to the work. The Predictive Maintenance P rocess is

based on earlier and ongoing data obtained and analyzed during the maintenance cycles.

LEVEL 1

- OPERATIONS SURVEILLANCE & AUTONOMOUS MAINTENANCE

Collection and review of process parameters along with routine observation of

machinery operations.

LEVEL 2

- RUNTIME BASED TESTING & PREDICTIVE MAINTENANCE

Scheduled collection and monitoring of c rankcase lubricant for effects of

degradation.

LEVEL 3

- CONDITION MONITORING & PREDICTIVE MAINTENANCE

Scheduled analysis of the motor and compressor performance, vibration profile,

and energy utilization

.

LEVEL4

- INTERMEDIATE INTERVENTION & PREVENTIVE MAINTENANCE

Scheduled driver tune

- up and testing /reconditioning of safety devices. Minimally

invasive, downtime required.

LEVEL 5

- PREEMINENT INTERVENTION & PREVENTIVE MAINTENANCE

Scheduled inspection and reconditioning of minor wear components in both the

driver and driven equipment. This includes a suite of maintenance task

considerations and milestone targets that are subject to the Predictive

Maintenance Process review prior to execution.

LEVEL 6

- ZERO HOUR TURNAROUND & PREVENTIVE MAINTENANCE

Scheduled overhaul of driver and replacement of major wear components. This

includes a suite of maintenance task considerations and milestone targets that are

subject to the Predictive Maintenance Process review prior to execution.

### The following pages describe the Level 1 tasks performed by the plant operators during

each shift.

Critical monitoring devices for pressure, temperature, level, and vibration are equipped

with High and High

- High alarms. High alarms warn operators of a process malfunction

allowing operators to troubleshoot the process for operational or mechanical

malfunctions

. Operational problems are corrected by an operator allowing equipment to

continue operating. Mechanical problems that can be easily repaired by the operator are

repaired. Mechanical problems that cannot be repaired by the operator are

communicated to the supervisor on duty and a decision is made to either shut down that

piece of equipment or to continue running, depending on the criticality of the equipment

and/or the severity of the malfunction, until repairs can be made. Monitoring frequency

of the equipment will be increased, again depending on the criticality of the equipment or

the severity of the malfunction until repairs can be made.

High

- High alarms will automatically shut down equipment ensuring the safety of

personnel

, preventing damage to equipment, and minimizing impact on the environment.

The supervisor on duty is notified of a shutdown and a decision is made whether to

repair immediately, depending on day (weekend, weekday), time of day ( night tour or

day tour ) availability of parts and personnel necessary to perform repairs, in order to

minimize impact on the environment.

Control Room.All valves, switches and breakers referenced in this procedure MUST BE LOCKED AN D TAGGED per the Lock

- out /

Tag

- out guidelines.

1. Isolate the compressor for maintenance.

NOTE Refer to the HOS

- 6 Operating procedure for requirements to shutdown the compressor. This procedure is for total

compressor isolation. Dependant upon the maintenance work required, specific cylinders or utilities may be

isolated separately, while leaving the remaining cylinders or utilities in service.

1.1 Ensure that the pre

- lube oil pump is not running.

1.2 De

- energize the electrical breaker for the motor in the MCC building.

1.3 Close the 4th stage discharge isolation block valve.

1.10 Close all isolation block valve for the open drain.

1.11 Place the H2S and LEL Detection system in the "calibration" mode in the Control Room.

NOTE While the H2S and LEL Detection system is in the "calibration" mode, the sensors are still act ive and MUST be

monitored from the Control Room. Tag it with Pink BYPASS tag and Log in the LOG BOOK.

2. Depressurize the compressor for maintenance.

WARNING Atmospheric vents will release process gas that contains LEL, Benzene and H2S.

Caution: Any opening of kiene valves or any other valves will vent process gas to atmospherics to depressurize compressor

2.1 Open the blowdown valves on all stages to the Flare header to depressure the compressor.

2.2 Close the blowdown valves on all stag es to the Flare header.

2.3 Open the atmospheric vent valves on all four cylinder to verify depressurization.

2.4 Open the cylinder head and crank end kiene vent valves or any other valves to verify that the cylinders to be

worked on are depressurize and r emain clear of the vented area.

2.5 Notify maintenance that they may begin work.3. Completed Maintenance and Pressure check compressor.

WARNING Make sure all maintenance work is completed before returning the compressor to service and remove all

isolation locks and tags.

3.1. Pressure check compressor with process gas.

3.1.1 Close the atmospheric vent valves on all four cylinder stages.

3.1.2 Open all isolation block valves on the PSV's for the (1st, 2nd, 3rd and 4th stages, etc.)

3.1.3 Open all i solation block valve for the closed drain.

3.1.4 Open all isolation block valve for the open drain.

WARNING Make sure atmospheric vents valves or any other valves that were opened during blow down are closed before

pressurizing compressor with process gas.

3.1.5 Open the 4th stage discharge isolation block valve.

3.1.6 Open the 3rd stage suction valve downstream of the Glycol Contactor.

3.1.7 Open the 4th stage intercooler discharge block valve.

EQUIPMENT

ENVIRONMENTAL For environmental concerns, con tact Supervisor and or Environmental Health & Safety Supervisor

SAFETY For applicable safety requirements, refer to the Resolute Natural Resources Safety Manual and Safety Data

Sheets (SDS).1.0 Initial Startup.

NOTE Initial startup is performed following an extended compressor shutdown due to maintenance or turnaround.

1.1. Check that the compressor is ready for start.

• Maintenance work complete

• Temporary blinds removed and equipment restored

• Oxygen purged from compressor and piping

• Compressor and piping pressure checked using process gas

• Compressor isolation valves returned to service

• Safety devices, vents, and PRVs returned to service with isolation lock open.

• Instruments, controls, and electrical power returned to service

• Lock

- out/Tag

- out removed

1.2. Start compressor using normal startup procedure.

2.0 Normal Startup.

NOTE Normal startup is performed following a brief compressor shutdown or following an extended shutdown after

performing the initial startup checks.

2.1. Prepare the compres sor for start.

2.1.1. Check compressor is ready for start.

• Plant ESD and local panel shutdowns are reset

• Verify that the LEL, H2S and Fire systems are in normal operation

• Motor electrical breaker is reset and in service in the MCC building

• Control panel po wer on HMI

• Crankcase oil level with Mobil 505 oil

• Lubricator oil level with NGL

- 888

• Check Oil Day tank level Mobil 505

• Check Oil Day tank level with NGL

- 888

• Visually verify that all Suction scrubbers are empty

• Ensure that the compressor is depressurized

• Ensure that the manual block valves on the 1st stage suction and 4th stage discharge lines

are in the open position

• Ensure that all kiene valves and bleeder valves are closed• The 1st Stage Suction Pressure Controller (PIC

- 1700) resets automa tically to 10.4%

2.2 Start and load compressor.

CAUTION The compressor should not have more than 5 psig on the 1st stage suction. Depressure as needed to

prevent overloading the compressor motor.

2.2.0 Verify HMI permissive (Shutdown) is reset.

2.2.1 Sta rt the pre

- lube oil pump.

NOTE The pre

- lube oil pump switch is located at the southwest corner of the compressor skid.

Compressor Starting sequence

Warning : Ensure that all personnel are clear and motor starter, near free of the electrical power supply system components

immediately prior to starting motor. In particular do not stand in front of motor transformer or under aerial fuses. A

minimum distance of 25 feet should be maintained for unqualified personnel.

Rationale: Across the line motor starting creates approximately 6X full load current. Consequently the electrical system is

stressed during starting and the probability of failure is greater.

CAUTION After 2 unsuccessful starts; the compressor motor starter will trip a time delay in the MCC building and

prevent you from restarting the compressor. Verify the time delay duration in the MCC building.

2.2.3 Verify that the compressor oil pressure is above 35 psig.

2.2.3 When the compressor starts ups, the suction shutdown valve should open automatically and the Step
