It has a monopoly on the fixed line network and has a considerable market share of the mobile communications market after its acquisition of Celcom and merging with its mobile operation arm, TMTouch. Telekom Malaysia Berhad, DBA TM, is the largest telecommunication company in Malaysia. Their mobile services are provided over the 900 & 1800 MHz GSM band and as July 2005, the 2100 MHz UMTS band.
Maxis Communications Berhad is a leading mobile phone service provider in Malaysia. Using shortcode is currently not allowed. But their 3G network only can access in 384Kbps in their mobile and must activte this service using calling. This service is available for their prepaid,postpaid and broadband users. DiGi has a 3G network with name Turbo 3G, its also promoted 4G DiGi's Turbo 3G has a speed of 14.4Mbps HSPA.
DiGi primarily uses the GSM1800 band with the network code of 50216. is a mobile service provider in Malaysia. 5 Restaurants, hotels and other recommendation applicationsĭiGi Telecommunications Sdn.4 GPS and other navigation applications.The water depth in the APN area is approximately 135 feet. The closest gas network pipeline is 27 miles away at Papa Flow station. The APN structure is located in the North Seribu Platform area and it lies approximately 50 miles north of Jakarta, Java (see Figure 1). APN is expected to deliver 50 MMSCFD to the sales point. APN's reserves is about 14% of the total non associated gas.
About 35% of the gas deliverability is from the non associated gas. The gas development in ONWJ calls for sequential development of 19 different gas and oil fields over the life of the project. Developing gas assets such as APN, to meet the gas sales contract has become one of the highest priority in ONWJ development. These gas delivery contracts will expire in 2007. Currently ARII is contracted to deliver 260 MMSCFD with a 20% swing to Muara Karang for Power generation, 25 MMSCFD to Indonesian State Gas Company (PGN) for small to medium industries and 50 MMSCFD to Pertamina at Cilamaya for manufacturing fertilizer. Before getting the first gas sales contract the produced gas was used for fueling compressors and other platforms utilities. Up until September 1993, when the Indonesian State Electricity Company (PLN) awarded ARlI with its first gas sales contract, the emphasis was on exploiting the oil assets. APN development is planned to occur after the year 2000 (as local market demand dictates).ĪRCO Indonesia (ARII) has been operating the Offshore Northwest Java (ONWJ) concession since 1971. The APN Fullfield model gas and water production forecasts were used for studying optimum well locations and surface facility design and planning.
The gridding of the full field model was based on the results from a single well model grid sensitivity study. The MDT built a fullfield simulation model incorporating reservoir description data from the geoscientists, surface facility data from the facility engineers, and tubing hydraulics data from production engineers.
Optimizing reservoir development while meeting gas demand is the critical factor for APN development.Ī Multi Disciplinary Team (MDT) of reservoir engineers, geoscientists, production engineers and facility engineers was formed for the commercial development of APN. It is a challenging task to commercially developed a thin and low pressure gas reservoir such as APN. The APN Pre-Parigi limestone has very good permeability of one Darcy and porosity of 38%. The range of reservoir drive mechanism is from a weak peripheral water drive in the southeast region to an active bottom water drive in the northeast region of the APN area. The gas deposit in the APN area is characterized as thin (15 to 70 feet) and widely dispersed over a large Pre-Parigi carbonate limestone area of 620 sq miles. Offshore Northwest Java (ONWJ) Sea contract area. The APN structure is located in the North Seribu Platform area, approximately 50 miles Northeast of Jakarta in the ARCO Indonesia Inc. The APN gas reservoir is relatively shallow, 1450 feet subsea with an initial reservoir pressure of 730 psia. This paper presents the strategy of developing the APN gas reservoir.
