Wellhead Compression Applications or “Giving new life to your mature oil & gas fields”

• Surface pressure reduction • Increased gas volume • Liquid loading

Natural Gas Production

• Replacing/rerating centralized (old) compressor stations • Bringing additional compression capacity into mature fields • Distributing compression throughout the gas field according

to needs Gas Gathering

• Casing pressure reduction for enhanced oil production • Compression of flare gas

History of Hoerbiger WHC project ► Background of Hoerbiger Wellhead compressor project

► In 2012 a service contract was concluded ► In 2014 was extended until 2016

► 13 Hoerbiger Wellhead compressors were bought for: ► Replace 10 GK Bulbuceni Compressors Station

► Compressing approx. 2,600 boe/day ► Safety operation of compression process

► Availability of new compressors was under 95 %, due to: ► Technical defects ► High fluctuation of fluid rate and water cut, dirty gas

► Proposals solutions: ► Re-design different components of compressors ► Instillation of separation units and tested new unit “PALL ”filter

Technical characteristics of Hoerbiger Wellhead compressor:

Suction pressure: 6 barg Discharge pressure: 25 barg Gas rate: 395 boe/day

10 Hoerbiger WHC at OMV-PETROM April 2015

Current status of WHC project

► No. of Wellhead compressors in function: 11 units ► 2 units in stand by

► Availability of Wellhead compressors, over 95 % ► The unit filter was tested

► Solved the problems due to dirty gas ► Additional Gas compression: 54,300 boe/year ► Saving Gas consumption: 6,540 boe/year ► OPEX saving: 0.5 Mn Euro/year ► Payback time: 2,9 years

Special Challenge – Solids in the Gas Main reason for unit availabilities < 95 %: premature wear of parts (control valves, valves, piping, compressors, gas starters, etc.) and clogged filters. Solution: additional filter elements downstream of the units 1st trial: Pall Highflow® filters with 10 and 20 µm for liquids to analyze type, size and quantity of solids - 10 µm: 8 days with 35.000 Sm3/day; solids 8,2 mg/Sm3 - 20 µm: 12 days with 40.000 Sm3/day; solids 11,5 mg/Sm3

Special Challenge – Solids in the Gas

Test results: Mainly formation minerals (SiO2); no indication for corrosion products Average solids content: 10 mg/Sm3 gas Recommendation: type E604Y400 filters; rating for gas of 99,995 % for

particles > 0,3 µm

Hoerbiger WHC at OMV-PETROM

2nd trial: with recommended filter type E604Y400 to check efficiency (life time per filter up to Δp of 1,5 bar) Results: life times of up to 374 hours achieved

April 2015

Availability of Hoerbiger WHC Units 4 business models available: Sales of units: including start-up, training and specified spare parts Service of (sold) units: including spare parts and consumables, if

requested also capital goods; minimum availability f.e. 95 %, max. response time (depending on location)

Rental of units: “all inclusive”; min. rental period 2 years Operation of units: performance contracts; min. period 2 years
