GAS & CONDENSATE EXPORT SYSTEM

Export System Define as a point of selling the gas & condensate

which have high potential in market value. At this point the system will received dry gas and

dry condensate to be exported. Parameter to be observed in this system are:

Quality & Quantity Control of dry Gas & Condensate Produced

Pressure & Temperature of flow line Safety System Installation & Protection

System Overview


Quality & Quantity Control of Production Water content in dry gas represent the quality of

dry gas & condensate produced Using Glycol Regeneration System to remove

water content in gas. Removing water drop in condensate by using

dried gas. Water Content Monitoring

Dew Point Analysis Water in Condensate (WIC) Sampling Analysis QC using bottle sampler (MTAB Sampling)


Quality & Quantity of Production (cont..) Quantity produced gas & condensate to be

exported are measured by Fiscal Metering System.

Unit for measured gas is MMscf/d (Million standard cubic feet per day) and for measured condensate is BBl/d (Barrel per day)

In metering skid (Fiscal Metering) consist of; Turbine Meter Pressure Indicator Temperature Indicator Flow Meter & Indicator

All of the metering instrument above will measure their respected parameter.


Quality & Quantity Control of Production (cont..)


Pressure & Temperature Instrument will indicate the parameter on export

riser at drilling platform. The export trunkline is connected to the M1

Complex export pipeline to Riser B at E11 Complex, the correct pressure must be controlled to enter the trunkline.

The temperature must be maintained in accordance to reduce deformation of gas to become condensate.

To maintain flow assurance while exporting the production gas & condensate (Hydrate Formation).


Safety System Installation & Protection SDV & BDV were put in place to avoid damage to

the pipeline due to overpressure and minimizing high potential incident to be occur.

Spare train exist to ensure the metering instrument is given correct reading, also to do maintenance task to the instrumentations on either train.

Subsea export pipeline is insulated to protect from corroded, maintaining the life span of the pipe and to reduce temperature drop to the product while travelling on seabed.


Safety System Installation & Protection ( Cont..) Pigging Operation used to clean the pipe from

debris, hydrate formation and wax. Chemical Injection such as Corrosion Inhibitor CK-

981 were used to minimize the contact of the condensate flow current with internal pipeline, flushing the formed corrosion.

Chemical were injected at the dry condensate pipeline before joining to gas export line.
