Drilling Risks Associated With Hydraulic Fractures and Reactivating Faults Due To High Mud Weight/Pore Pressure and Miti
Authors A. A. Bal, D. Maya, K. K. Kyi, R. Guha, M. I. Gabreldar and D. Abang IndiIn the wake of the Deepwater Horizon accident, a proper safety process and qualification is being given highest attention in the industry. Process safety refers to the procedures for minimizing risk generally (Deep Water Final Report 2011, Chpt 8). One of these risks is deciding on the appropriate mud weight to balance the pore pressure without fracturing or damaging the formation.

Integrated Reservoir Characterisation of Turbidite Deposits within a Submarine Canyon, Offshore Sabah, Malaysia.
Authors K. Maguire, C.W. Hong, T.M. Ting and G. StoneOne of the main subsurface uncertainties that impacts waterflood and enhanced oil recovery (EOR) projects is reservoir connectivity. Reservoir connectivity is controlled by structure (faults) and stratigraphy (reservoir architecture). An understanding of structural connectivity in a field can often be determined by detailed structural mapping from seismic.

Authors K. S. Chan, R. Masoudi, B. P. Kantaatmadja and M. OthmanIn the quest of reducing the field development and production cost in Malaysia in the complex multi stacked compartmentalized mature fields, a new initiative is to couple the reservoir dynamic simulation with reservoir geo-mechanical modeling.

Deepwater Exploration in Malaysia, Offshore Sarawak
Authors P. Baltensperger, K. Robinson, A. Finlay and A. ThomasRecent exploration drilling by Newfield and their partners, PETRONAS Carigali and Mitsubishi Corporation, has proven a new hydrocarbon province in Deepwater Sarawak, Malaysia. The Newfield operated JV have drilled 2 wells since signing the Deepwater PSC in 2004 resulting in 2 hydrocarbon discoveries.

Hydrothermally Enhanced Fractured Reservoirs – A New Play?
More LessHave we ignored the possibility of hydrothermally enhanced fractured reservoirs as a play type in its own right? With the exception of Nang Nuan (Heward et al, 2000) and some references to the fractured granites in Vietnam (e.g. Hung and Le 2003), hydrothermally altered hydrocarbon reservoirs are largely unreported in the rocks of Southeast Asia.

“Pre-MMU” Carbonates and the Influence of Age and Tectonic Regimes on Their Growth Styles, Sarawak, Malaysia
Authors E. W. Adams, R. E. Besems and S. J. GoughIn Shell, recent exploration activities have focused on portfolio rejuvenation and play-based exploration (PBE) studies to assess the remaining exploration potential of onshore and offshore Sarawak. Historically, in Sarawak, carbonate exploration has mostly focused on the renowned Middle to Late Miocene Luconia Province carbonates.

Sepat Barat Deep-2: The Deepest and Hottest HPHT Well in North Malay Basin
Authors S. Osman, M. F. Nianamuthu, F. A. Ismail, J. J. M. Idris and J. PingSince the late '60's, exploration activities had started in the North Malay Basin region which resulted in the discoveries of Jerneh, Lawit, Bintang, Damar, Noring, Guling and Tujoh by several operators (Figure 1).

Brittle versus Mobile Shale Tectonics in Deltas: Structural Constraints Derived From Regional Seismic Interpretations
Authors P. A. Restrepo-Pace and Mubadala OilMany deltas e.g. NW Borneo exhibits extensional growth systems landward and compressional structures at the present day slope and deep-water positions. The link between the extensional and compressional systems is hard to pin down as deep seismic data is of poor quality in these areas.

Maturation of a New Play Concept in Northern Provinces of Offshore Sarawak Basin, Malaysia
Authors S.R. Iyer, H. Rosidah and A. Shahrul AmarNorthern provinces of Offshore Sarawak Basin represent a frontier area with low well density and relatively fair understanding of the petroleum system. Hydrocarbon prospectivity evaluationintegrating seismic, gravity, and well data of northern provinces of offshore Sarawak facilitatedmodeling of tectono-stratigraphic framework and geological evolution of the area, culminating in thedevelopment of a new play concept, hitherto untested in this part of Sarawak Basin. Stratigraphy ofthe study area is characterized by a lower synrift sequence, consisting of transitional to shallow marine sediments, unconformably overlain by passive margin sag phase deep water sediments.Exploration to date has focused on hydrocarbon plays in upper part of synrift section. Present paperdeals with maturation of Sequence-A play as a new concept, primarily based on seismic evidence.This sequence, consisting of postulated lacustrine sediments, filled the early formed half grabensduring the first phase of extension. Uplifted sections of this sequence on footwall closures arepotential hydrocarbon plays with charge from adjoining grabens. Regional review of equivalentsections suggests clastic sequence similar to Sampaguita-1 as the most likely analogue. Proving this play will open up substantial exploration potential in the northern provinces of Offshore Sarawak Basin, with significant economic value.

Tectono-Stratigraphy and Development of the Miocene Delta Systems on an Active Margin of Northwest Borneo, Malaysia
Authors A. Balaguru and T. LukieThe Paleogene regional tectonic setting of Sabah is very complex with southeasterly subduction of the proto-South China Sea in NW Borneo (Hall, 1996), followed by a period of continued deposition of deep marine Rajang Group turbidites. The Late Eocene tectonic deformation is characterized by folding, thrusting and regional uplift related to the collision of the Luconia Continental Block against NW Borneo (Sarawak Orogeny; Hutchison, 1996).

Integrated Bio- and Seismostratigraphy of the Southern Sabah Offshore, Malaysia
Authors J. J. Lim and Sarawak SHELL BerhadRecently, the Sarawak Shell Berhad Biostratigraphy team has reviewed a selection of key wells from the Southern Sabah Offshore, and has built a consistent biostratigraphic zonation and framework, largely based on nannoplankton and planktonic foraminifera. The biostratigraphic zonation has been tied to regional seismic lines in order to create a robust bio- and seismic stratigraphic framework. A work flow has been set-up and the value of such an approach has been demonstrated in the regional evaluation projects.

New Joint Categorical/Continuous Simultaneous Inversion Technology
More LessIn this paper we will first review the industry-standard continuous simultaneous inversion methods and point out some shortcomings. We will then introduce our new joint categorical/continuous simultaneous inversion technology, which reformulates the problem to address these issues. We present some examples and wash up with conclusions.

Petrophysical Evaluation of “Quasi Wet Pay Zones” (QWPZ) via Integration of Advanced and Conventional Wireline Data
Authors S. Ismail, M. M. Altunbay and N. AulaA “low resistivity-low contrast” (LRLC) and low porosity-permeability sand earns a new name “quasi-wet-pay zone” (QWPZ) encompassing the hindrances of recognition due to lesser conductivity-contrast and diminished hydraulic properties. As we know from each components of this new definition, the evaluation of QWPZ sands by traditional methods has historically proven to be inadequate in deciding if the testing/completion/stimulation of a zone(s) is economically feasible.

Evaluation of Thin-Bedded Heterogeneous Sands Using Geophysical Applications & Well Data for A Robust Development Plan
Authors M. S. Mohd Adnan and F. FahmiA comprehensive technical evaluation was conducted in a gas field in the Malay Basin, offshore Peninsula Malaysia, to describe the degree of reservoir heterogeneity in the thinly stacked non-associated gas (NAG) reservoirs in the Middle Miocene Group D and E sandstones. This paper focuses on two major reservoirs, D-1 and E-1, using AVO modeling and seismic Vp/Vs inversion with well log and MDT pressure integration to better understand sand distribution for subsequent drillwell development planning in 2014.
