A Structured Approach Towards Quantification of Subsurface Parameter Ranges
Authors A.J.W. Everts, L. Alessio, P. Friedinger and F. RahmatObjective of this paper is to illustrate how a structured approach towards quantifying the expectation ranges of key subsurface parameters, differentiating between true uncertainty and mere variability and recognizing the possibility of biases in our subsurface data, can lead to significantly improved asset management, i.e., better reservoir models, improved accuracy of resource estimates, more objective assessment of appraisal value etc.

A Sedimentologic and Petrographic Perspective of the Miocene Stage IVA from the Klias Peninsula to Labuan Island
Authors T.D. Lukie and A. BalaguruThe Miocene outcrops in NW Sabah provide an opportunity to study the rocks equivalent to the offshore reservoirs undergoing exploration. The primary target for most exploration is the Stage IV (Figure 1) and it ranges in thickness from 3 to 5 kms and comprises interstratified sandstones and shales deposited within marginal marine to shoreface environments. The Stage IVA which is the focus of this study, sits on the Middle Miocene Unconformity (MMU), also known as the DRU (Deep Regional Unconformity) and marks the onset of the next major phase of sediment accumulation (after Early Miocene Stage III) in NW Sabah.

An Integrated Approach Towards Delineating Hydrocarbon Prospectivity in Untested Fault Blocks Within a Brown Field. A Case Study in B Field, Offshore Sarawak, Malaysia.
Authors A. Azami, A. Hashim, N. Alias, N. Ujal, M. Bhattacharya, A. Roy, S. Pamungkas and T. AldhaB Field is located approximately 80 km from Bintulu in water depth of about 90 feet, Balingian Province, offshore Sarawak, Malaysia. In was discovered in 1976, with first oil achieved in 1984. Since then, more than 70 wells have been drilled, with production coming from three main accumulations: B North, West, and Northwest.

Integrated Geoscience Interpretation of Selected Group B Sands In Beta Field, Malay Basin
More LessBeta Field is a non-associated gas field located about 220 km north of Kerteh in water depth of 60 meters,. The field was discovered in 1970 and development of the Group “B” sands began in 2003 with first gas in March 2003. The Group B sands were not targeted during the initial field development. The field is a broad, low relief high side fault dependent closure in the northern part of the Malay Basin. In this paper we will briefly examine future development of the shallow and likely unconsolidated B-A, B-B, B-C, and B-D reservoirs in Beta Field.

Geohazards Assessment, Data Integration and Visualization via ArcGIS
Authors M. Zulkifli, D.A. Bean and T.K. TiongGeohazards are geological features on the seafloor or in the subsurface that may pose drilling and/or development-related issues (e.g. infrastructure placement). Geohazards are conventionally assessed qualitatively via seismic interpretation and the evaluation of site survey geophysical data such as high resolution 2D seismic, multibeam bathymetry and side scan sonar.

The Evolution of Tiltmeter-Based Reservoir Monitoring: From Risk Mitigation to Production Optimization
Authors S. Marsic, M. Machovoe and W. RoadarmelTiltmeter technology has proven extremely valuable in heavy oil recovery fields as shown by the increasing installations worldwide, a 15+ year history of monitoring success in regions such as the San Joaquin Valley in California, and now an increasing regulatory demand for its operational use. The use of tiltmeter diagnostics has been a widely accepted tool for mapping of fracture stimulation treatments, but also fulfils a need for a cost effective, near real-time reservoir surveillance tool in thermal enhanced oil recovery (EOR) environments.

Key features of TEM and EM-IP investigations in South-East Asia
This paper reports the characteristics of an onshore EM survey recently conducted in the South-East Asia region. The survey area is located on Northern part of the Borneo island (Sarawak, Malaysia) and is characterized by specific natural and geographical conditions and therefore the production work was complicated by several factors.

CSEM Application in Carbonate Environment: A Case Study
Authors A. S. Saleh, S. K. Chandola, P. K. Lee, T. Velayatham, P. Kumar, M. S. Wahid and J. BeenfeldtApplication of Controlled Source Electro Magnetics (CSEM) method as a derisking tool has found increasing application, particularly in deep water environment. CSEM provides resistivity distribution in the subsurface to differentiate between hydrocarbon and brine-filled reservoirs. However, the application of CSEM method in carbonate reservoirs has been rare due to the inherent inhomogeneity associated with carbonates.

Application of TTI Reverse Time Migration, Deepwater Offshore Malaysia
More LessIn this paper we present a case history of applying TTI RTM (Reverse Time Migration) for imaging in a deep-water area offshore Malaysia. Use of RTM is not new but examples tend to come from areas such as the Gulf of Mexico and North Sea and as such, the example presented here may be the first of its kind in South East Asia.

Studying Carbonate AvO Response
Authors Y.F. Tiong and Sarawak Shell BerhadAvO inversion has not been done for carbonate fields because carbonate rock does not normally display AvO effects. However, there is no hard evidence for that, so this project was setup to investigate if there are any meaningful AvO effects in Sarawak carbonates.
