Chapter-1 Introduction

1.1. BACKGROUND

has planned a gasfield, whichis Province;this is the complying withLawofregarding Upstream Oil

and Gasthe Implementing Body () of Oil and GasLawofregardinga company thatPERTAMINA

handlesiesUpstream Oil and Natural GasPERTAMINAis basedonD

PPGM is an important project for oil industry and natural gas in Indonesia and will play

important roles in maintaining and strengthening Indonesia position as the biggest exporter of

LNG in the world. The development of PPGM will improve contribution of oil and natural gas

sector in rendering foreign-exchange to the country and partly for substitution of domestic oil

fuel. LNG Arun in Nangroe Aceh Darussalam Province is experiencing of production degradation.

Therefore, this LNG Project will strengthen the production of marketable LNG in Indonesia and


I-2


will become the fourth export center of LNG in Indonesia. PPGM is expected to operate in year

2012.

The development of Matindok Gas Project is an activity of developing complete facilities, starting

from producing natural gas from both explorated and developed wells plan coming from 5

natural gas fields, including: gas field of Donggi, Matindok, Maleoraja, Sukamaju, and Minahaki.

Later, the gas is channeled through pipe to LNG refinery, then the gas is transported to through

harbor using LNG oil tanker.

The gas production capacity of Matindok Block is 100 MMSCFD (gross), with condensate

content of 850 bopd, and produced water is 2500 bwpd. The predicted gas producing time

is 20 years based on the level of existing gas reserve and result of economic study of field

development. The produced gas contains CO2 2,5%, totalizing Sulphur 3.000 ppm and there

is possibility of containing the other element.

as follows:

1. Providing stock of Gas, Liquid Natural Gas (LNG), liquid hydrocarbon (condensate) and

sulphur

2. Increasing the Income of Banggai Regency (local level), Central Sulawesi Province

(regional level) and national level through royalty and tax of sales revenue of LNG,

condensate and sulphur

3. Giving employment and business opportunity to local society, national and regional

4. Increasing ability of Nation in mastering, handling of gas producing technology

On the other hand, the development of Matindok Gas Project is also presumed to generate

negative impacts to certain environmental component. Therefore, PT Pertamina EP PPGM has

an intention to conduct an Environmental Impact Analysis (AMDAL) before conducting the

construction. This complies with the company commitment to participate in environmental

protection in its each activity. The EIA (AMDAL) is conducted based on the Law No. 23 of 1997

regarding Environmental Management, the Government Regulation No. 27 of 1999 regarding

Environmental Impact Analysis (AMDAL), and also the Regulation of State Minister of

Environment No. 11 of 2006 regarding Type of Business Plan and/or Activity which is obliged to

(total = 12 ha); as for the BS construction is in 3 locations (45 ha each); theflowline in 5

locations need 8 m width x 35 km length of flowline (14 ha); The LNG Refinery area is 200

ha; and the gas piping system needs 20 m width x 60 km length of pipe (120 ha). This

location needs to be prepared before drilling the development wells, by the road

construction directed to the location (construction of the new road and development of the

existing road) with the cumulative length from all wells is 15 km with 6 8 m width (

60 ha). Besides, the construction of harbor and its facilities (Jetty) will require area of 10

Ha. Therefore, the area needed for the project is 461 Ha. The area which is used belongs

to the society or others. The acquisition of area will be done according to the existing

regulation.

B. Production Capacity

PT. PERTAMINA EP plans the Matindok Gas Development Project which is started with the

wells drilling activity for production facilities in Matindok Block, the Block Station (BS)

construction, gas processing facilities (GPF) and construction of gas pipe transmission

(flowline and trunk line), also LNG Refinery construction along the harbor as a

transportation line for LNG or Sulphur which is produced outside the Banggai Regency.

The gas production capacity in Matindok Block is 100 MMSCFD (gross), with the

condensate content of 850 bopd and produced water 2500 bwpd, and estimated gas

production period is 20 years, based on the amount of the gas reserve and the

economical analysis. The produced gas contains CO2 2,5%, Total Sulphur 3.000 ppm

and other possible elements.

The facilities of gas production, which will be constructed, are Gas Wells, Flowline,

Gathering Line, Block Station and Gas Processing Facility (GPF). The transmission pipe from

GPF into the LNG Refinery is planned to have 34 size for 25 km of length with the

major part is situated at 500 m far from off shore, parallel with the highway.

The element content existed in the gas production can be seen completely in Table 2.2.

D. Types of Energy Source and Water Source Needed for the Activity Plan Location.

The types of main energy to support the operation of production facilities are:

1. Gas Fuel which is needed to operate different kinds of facilities including Gas Dryer, Gas

Threating Unit, and Gas liquefied into LNG Compressor Activator and Electricity Generator

activator. Gas fuel will be taken from the production result itself.

2. Generator unit with oil fuel which is prepared for the emergency in each BS, LNG refinery

and Seashore/Harbor. The oil fuel comes from Pertamina refinery.

3. The electricity, which is generated from gas fuel generator, is used for lighting and

electricity motor activator.

The amount of water needed for the drilling is quite big, around 420 m3 per well, hydro test

pipe channel around 20.000 m3, and for every BS unit operation is around 25 m3/day. The

water needed for the construction will be taken from the river or the closest water pool.

The water needed for an operational LNG refinery is around 75 m3/day which will be taken

from the deep groundwater.

The location of PPGM activity plan is presented in Figure 2.4.

1) Socialization

The announcement of activity plan is already done through newspapers, posters, local

private radio and banner.

2) Public Consultation

In order to arrange the Term of Reference (KA-ANDAL), the public consultation has

already been held in two places, on Tuesday, May 23rd, 2006 in Batui District and May

24th,, 2006 in Toili district, between PT Pertamina-EP and the society of Banggai

Regency. Those meeting were presented by PT Pertamina-EP delegation, the deputy of

Ministry of KLH, The Dirjen Migas, Local Government of Banggai Regency, EIS Study

Team from PSLH UGM-PPLH UNTAD, also the communities of Batui, Toili and Toili Barat

districts in Banggai Regency.

Based on the observation and evaluation of information including suggestion, opinion,

and society response, local government, and the other relevant institution which

connected with the development activity plan, there are several suggestions which need

to be consider:

Land acquisition and plants compensation Local Labour Society Act program The existence of offshore coral reef The existence Bangkiriang Wild Life Conservation

All suggestions, recommendations, and ideas will be taken into consideration in the

project design and, will be put in to the EIS document, if there is no contradiction.

F. Drilling Activity

1. The well Drilling

Geologically, Matindok Block area and its surrounding are located in Banggai basin, in

the southern side of the eastern arms of Sulawesi Island. Banggai basin is the main part

of offshore depression along the coast in the southeastern of the eastsea of Sulawesi,

which is not in a symmetrical shape with N60E of slope along the coastline. This basin

is classified in the transform refted basin, which is an active margin basin or collision

related basin. The regional stratigraphic of Banggai basin can be seen in Figure 2.5.



This area has potential hydrocarbon and has been proved on producing hydrocarbon in

carbonate rock formation of Tomori and Minahaki formation.

Until February 2006, the 12 drilling wells in Matindok block are already done, with 9

wells are successful in finding gas in five structures (Donggi, Matindok, Maleoraja,

Sukamaju and Minahaki) and 3 dry wells. The well drilling is still possibly operated in

this Matindok block. This is because based on Geological and Geophysical analyses,

there are several prospects of potential hydrocarbon content.

Figure 2.5. The Regional Stratigraphy of Banggai Sula Bassin, In The Eastern-arms of Sulawesi

2. The Drilling of the Development Wells

The results of several well drilling exploration which was already done in this Matindok

block show that there are five structures having gas content, those structures are



onshore. The gas reserve (already taken) which has the certification from the six

structures is approximately reach 696 BSCF gas (P1).

Based on Geological, Geophysical, and Reservoir (GGR) analyze from those six

structures, the project is planned to drill 18 development wells (Table 2.4), with the

possibility of dry well. The types of well drilling activity include well development (18

wells), work over (6 wells), stimulation, well caring, dan well closing.

The drilling equipment and its capacity are in conformity with the drilling target.

Besides, it still use another support equipment operation such as air compressor,

cement mixer and pump, cement storage tanks, electric wire logging unit, mud pump,

mud logging equipment, desender and desilter, truck and trailers, water pump, blow out

preventer, etc.



3. The Production Wells

Once the drilling process is completed, it is continued with well completion along with

arranged program, such as assembling of production string, wellhead and Christmas

tree.

G. Gas Pipe System

1. Pipe Line

The results of gas production from each well run through the production pipe (flowline) with

the suitable diameter into Block Station (BS) and Gas Processing Facility (GPF). The area

width, which will be used for this production, is around 8 meter with the cumulative length

35 km for 18 wells. The Layout from each location of Block Station and flowline are

resumed as seen on Figure 2.6 2.10.

Those flowline designs are based on ASME/ANSI B.31.8. and GPSA Hand Book.

Figure 2.11. Flowline Diagram

The MS gas runs through the suitable pipes 14, 16, 18, 20 to the processing gas

facilities. Gas from BS Donggi-Minahaki and BS Matindok-Maleoraja runs to the LNG Plant.

Meanwhile gas from BS Sukamaju processed and directly transported to the IPP Banggai.

The gas processed in BS at Donggi and Matindok which have standard gas content will be

sold to the LNG refinery at Batui or Kintom. The gas delivery from GPF Donggi is done

across the pipe, which has 16 diameter with the pipe length is 40 km up to the next

Junction, then it is channeled through pipe with 34 diameter to the LNG Plant. The gas

delivery from BS Matindok is done across the pipe with 16 diameter (3 km length) up to the

junction, and then it is channeled through the same 34 diameter pipe to the LNG Plant. In

order to get 773 psi of gas pressure on the 34 diameter pipe, there will be compressors

placed in BS Donggi and Matindok.

2. The Pipe Design

The pipe design and pipe setting will refer to several national standards (for example,

regulation of Department of Mining and Energy regarding Oil and Natural Gas Refinery No.

SL Specification for Line Pipe, API 1104 Welding of Pipeline and Related facilities, ASME

B31.8 Gas Distribution and Transportation Piping System). Technically, the pipe design

can be used for minimum 30 years. The pipe connection will be done by specific certified

personnel.

3. Pipe Corrosion Protection

The outside gas pipe corrosion protection is done by the cathodes protection system (anode

carbon) which is expected to be able to control all kinds of outside pipe corrosion

underground in order to protect the pipe from outside corrosion. Besides, this pipe is

completed with outside pipe coating which is also functioned as protection from outside

corrosion. The internal corrosion protection is done by periodic injection corrosion inhibitor

into the gas pipe.

To facilitate the measurement of potential and flow in the pipe, a test box is set up in every

1 km.

H. Block Station (BS)

The gas from the production wells is flown in to 5 gathering stations/Block Stations placed in

each fields (Donggi, Matindok, Minahaki, Sukamaju and Maleoraja). Inside the BS, there are

separation unit, the dehydration unit, compression unit, receiving tank, utility unit, waste

flaring system and IPAL. The following are the operation units, which are used for the gas

processing in BS. The entire Block Stations in the Matindok block consist of Gathering

System and the system separation of natural gas that consist of separator, condensate, and

dehydration unit. The dehydration unit is needed to reduce the water content in the natural

gas to reach the specification gas pipeline, which are 7 lb/MMSCF at maximum.

1. Separation Unit

The Hydrocarbon from the production wells contains condensate, water, and gas, where

the major production is gas. The first step to separates condensate, water, and gas is

using gas separator. Inside the equipment, condensate and water are separated from

the gas. The condensate and water will flow from the bottom part of the separator while

the gas will flow from the upper part. The separation process inside those equipments is

a physical process without chemical material addition.



The condensate and water are separated based on the principle of non-dissolve and the

differences of mass density. The condensate is received in the storage tank, the water

will be continuously processed with the wastewater treatment.

If the gas pressure from the well decreased because the reservoir pressure naturally

descends, it will need the compressor assembling in the Gathering Station/Block Station

to keep the stability of gas pressure that comes in to the CO2 / H2S Removal System or

into the gas consumer.

The condensate is kept in the storage tank to be delivered to the LNG refinery in Batui

by road tank. Figure 2.12 shows the system of the gathering station/block

station.

2. Dehydration Plant

Once the gas comes out from the separation unit, it will be channeled to the

Dehydration Unit. The function of Dehydration plant is drying the gas to complete the

process of water reduction. The process includes water absorption process by using the

chemical material triethyleneglycol (TEG) which can be re-used after being physically

Figure 2.12. The Flowchart of Block Station/Gathering Station. explanation: HP (high pressure), MP (medium pressure), LP (low pressure),

KO (knock out), AGRU (acid gas removal unit)



cleaned from the water (close cycle). The results of those processes are the qualified

gas for the consumer. Figure 2.13 presents the schema of dehydration plant.

Figure 2.13. The Works Scheme of Dehydration Plant

3. The Receiving Tank

The receiving tank is used for receiving the condensate that comes from the separator,

before it is transported to Batui. The number of receiving tanks being used are 2 tanks

with the capacity of each is 1300 m3. The condensate will be transported from Block

Station to the LNG refinery in Batui by road tank.

4. The Compressor

The compressor will be used to keep pressure out from Block station, so it is maintained

at 900 psig. This compressor is set up in the block station and it is done after the

pressure from the well gas is less than 900 psig. The number of compressors being

placed in the Block Station are 3 units per location in average. This is because generally

the gas pressure that comes out from the wells will be naturally going down during the

production process, so it needs more new compressor in the Gathering Station/block

station.

5. The Water processing unit

The Water processing unit or Unit of Effluent Treatment or the installation of

wastewater processing (IPAL) is used for processing the liquid waste that comes from

the separator and others.

6. CO2/ H2S Removal (AGRU)

Before entering the LNG Refinery, the CO2 and H2S content will be reduced by an

absorption process using MDEA (Methyl DiethanolAmine) condensation inside the Acid

Gas Removal Unit (AGRU). The main function of the unit is to absorb CO2 and H2S

content inside the absorber and release them to the stripper tower or column, to obtain

the sweet gas with low CO2 and H2S content. Figure 2.14 shows the flowchart of Acid

Gas Removal Unit. The gas from 5 Block Station is flown across the pipe to the Acid Gas

Removal Unit which is placed in GPF in Kayowa or in the LNG refinery.

Acid Gas Removal Unit (AGRU)

The main function of AGRU is dump the carbon dioxide dumping. The carbon dioxide

dumping is required to prevent freezing and clogging problems in the lower temperature

that is used inside the liquefaction unit. The concentration of carbon dioxide

concentration inside the gas stream will be reduced to 50 parts per million volumes

(ppmv) with the amine-based solution absorption. This activity is closed-loop and

regenerative so that the absorbed carbon dioxide will be lifted from the carbon dioxide-

rich solution. The lifted carbon dioxide will be released to the air, and the amine solution

that is free from carbon dioxide will be returned to the absorption phase.

The amine-based solution which is used by all AGRUs is also able to remove the entire

sulphur mixed that is already reduced but probably is still resided in it (ex: sulfide

hydrogen, mercaptan, and others). Nevertheless, the compositional analysis indicates

that the sulphur which is left inside the feed of natural gas is only just a little amount or

none.

7. Sulphur Recovery Unit (SRU)

The purpose of sulphur recovery is to comply with environmental regulation concerning

threshold values as stipulated in the State Minister Decree of Environmental Affairs

No.129 of 2003. There are several processes available to produce the sulphur from

hydrogen sulfide. Some processes have been designed to produce sulphur and some

others are developed with the main purpose is to remove the H2S content from th
