Abstract
The risk of oil spills is high in the Straits of Melaka. Oil spills caused by collisions of ships and illegal dumping or discharge of oil in the Straits have resulted in massive environmental pollution and degradation along extensive stretches of the West Coast. To mitigate the effects of oil spills, a contingency plan based on assessment of effects of such incidents should be formulated. As a start, an investigation of the vulnerability to oil spills of the coastal environments in Perak was carried out in 2000.
A preliminary classification of the vulnerability of a number of coastal facies was generated based on the Vulnerability Index of Gundlach & Hayes - which uses a scale of 1 to 10. Tidal flats and mangrove swamps were given an index of 9 to 10, as any oil spill would destroy most of the flora and fauna. Sandy beaches are placed 4 in the Index, as an oil spill would result in the oil sinking rapidly into the coarse sand. The rocky headlands, which are mostly exposed to the open seas are not vulnerable and have a scale of 1.
Re-mapping of these coastal environments by remote sensing methods is currently underway. Ground-truthing is complemented by detailed assessment studies of the impact of oil spill on the sediments. Field tests are carried out on selected representative stretches of the beaches, tidal flats and mangrove swamps to characterize their physical properties and to study the infiltration rate of oil into such lithologies. The new maps generated in this study should provide the Perak State Government with the best tools to formulate an updated contingency action plan in the event of an oil spill.

Abstract
In the past, thin reservoirs (less than 30 ft.) were considered economically unattractive due to typical low production rates. The development of modern drilling and real time logging technologies have made it possible place horizontal wells by geosteering within good porosity sections of very thin reservoirs. This have been a game changer for development of thin reservoirs as it is now feasible to drill wells with sufficient reservoir contact to yield commercial oil production rates.
In 2003, Saudi Aramco drilled the first Maximum Reservoir Contact (MRC) multi-lateral well for exploitation of thin reservoir sections. At this point in time, MRC wells completed with smart inflow control valve (ICV) completions have become the standard Saudi Armco well type for thin reservoir developments.
The introduction of advanced technology has helped to reduce well placement uncertainty and increase reservoir contact by utilization of directional and deep resistivity tools for boundary detection combined with close to bit measurements from high resolution resistivity borehole imaging tools to monitor variation in formation dip.
This poster would demonstrate successful placement by deep resistivity boundary detection geosteering of a very challenging multi-lateral MRC well drilled in an onshore carbonate field in Saudi Arabia. This well presented unique geological challenges in terms of formation dip, reservoir thickness and carbonate facies variability by virtue of its location on the flanks of a dipping anticlinal structure.

Abstract

Description
This paper describes the project management processes used to design and procure the topsides facilities for the Gumusut-Kakap project.
Gumusut-Kakap is a "mega-project" to be installed in Malaysian deepwater to produce up to 150,000 bpd sales quality oil whilst injecting up to 220,000 bpd seawater and up to 300 MMscfd gas to the reservoir. The topsides facilities are thus world-class in scale. They will be supported on a new-build, moored semi-submersible, receiving production from subsea wells. Interfaces between the topsides and the hull, the subsea systems and the export pipeline are complex and are described in the paper.
The topsides execution strategy is aligned to the project's drivers: Safety, Technical Integrity, Capability Development, Schedule and Cost. These drivers were enforced throughout the FEED phase which was executed in Shell's US design centre and the Detailed Design phase which was transitioned to a Malaysian EPC contractor to facilitate Capability Development, Schedule and Cost. The challenges, plans and learnings from this transition are described in the paper.
The project management processes developed in Shell's deepwater projects group were adapted for the Gumusut-Kakap project and used to support the EPC contractor. Key processes implemented include: Design Verification, Weight Management, Interface Management and Flawless Start-Up, enabled through key Information Technology (IT) tools. These processes and their customisation are described in this paper.
The results presented in the paper will be applicable to mega-projects, especially those in areas developing local capabilities.
The conclusions are:Alignment of stakeholders on the project drivers is vitalContractor capability is a key areas to address in transition planning and capability developmentProject management processes need to be customised for the particular project
The technical contribution of this paper is through:Base plan for transitioning a design from a company center to the host countryImproved techniques for developing capability of key contractorsEnhanced tools for managing complex project interfaces

Abstract
Basements rarely form hydrocarbon reservoirs; and consequently are rarely considered as hydrocarbon exploration targets. The few basement reservoirs are classified as unconventional reservoirs.
In addition to the usual uncertainties in hydrocarbon exploration, three additional components are necessary for the success in basement reservoir exploration; Time lag between the peak time of hydrocarbon generation and tectonic movement that create fracture systems in the basement,contact area between source rocks and basement surface andlimited migration paths.
In the Sabatayn basin, Yemen, the Jurassic Kimmeridgian Madbi shale is the source rock and regional evaporites seal the entrapped hydrocarbons. The shale expelled the hydrocarbons during early Cretaceous into previously fractured Pre-Cambrian basement.
Integrated interpretation of gravity and 2D seismic data defined the poorly imaged basement highs in the basin. This work provided a cost-effective evaluation method for identifying basement highs forming the hydrocarbon reservoirs.

Abstract
Reservoir distribution and quality in an active slope setting are controlled by the evolution of slope accommodation and patterns of sediment input onto the slope. This presentation outlines the workflows and key findings of a regional study attempting to reconstruct the slope depositional history and improve reservoir prediction in an area of 8,000km2 offshore Sabah, Malaysia.
To identify depositional systems and map their evolution through time, a high-resolution sequence stratigraphic framework needs to be defined. Deepwater stratigraphy in the NW Borneo relies on the interpretation of gross seismic architecture supported by bio-stratigraphic analysis. The loop-scale seismic architecture calibrated t over 35 wells is a basis for the interpretation of depositional environments within each sequence. On a smaller scale, core-based sedimentary facies combined with wireline log motifs is used to elucidate sub-seismic reservoir heterogeneity.
Clear definition of the architectural elements of different scales is key to ensure consistency of the interpretations. It also creates a basis for the statistical analysis of reservoir properties and depositional body geometries. The focus is on distinguishing between different depositional system elements, such as the high net:gross amalgamated distributary channels occurring in the slope aprons and the more heterolithic meandering type of submarine valleys. Equally important is the correct placement of sheet-like layered deposits in a levee or lobe fringe environment.
Depositional system elements (DSE) define basic semi-regional reservoir characterization units, which differ from each other in geometry and the degree of internal sand body connectivity. At a higher level, DSEs merge into distinctive depositional environments with specific sand distribution patterns and the chances of reservoir-seal occurrence.
Hierarchical reservoir classification workflow allows the comparison of various data types from different parts of the basin and increases the chance of correctly predicting reservoir presence and quality in un-explored deepwater acreage.

Abstract
About 20% of the wells on the Norwegian Continental Shelf suffer from integrity problems. Often these are leaks in tubing or casing. Subsea wells have in general no access to closed annuli, so thermally induced pressure buildup cannot be relieved. On platform wells WAG wells are in particular thermally loaded because of the cold water injection followed by periods of hot gas injection. Because industry lacks data an experimental program has been carried out at the University of Stavanger. Drilling fluids, completion fluids and packer fluids have been tested to derive compressibilities and thermal expansion coefficients from ambient temperature to 150B: C. For some fluids these deviates significantly from the textbook values used in the oil industry today. The paper will present these data in form of tables. Several field cases will be presented using the new data. The first case shows the B-annulus pressure buildup in a HPHT well. A second case analyse the loading on a WAG injection well, where the cyclic thermal loading led to connection leaks. The third case compares the solutions with the new data with the textbook values showing the error. The thermal loading aspect has significant impact on well construction and well operations. The compressibility and thermal expansion data provided are not published before, and are significant new technical contributions.
Complex Seismic Morphology on the Slope of NW Australia: Successive Episodes of Fossil Pockmarks in the Lower Tertiary

Abstract
The Tertiary slope deposits of the Australian NW shelf show a complex imbrications of apparently erosional surfaces. Observed in 3D, these surfaces appear as essentially made up of coalescent craters. This morphology indicates that they do not correspond to canyons or channels as could be suggested by cross-sectional views only. Detail seismic correlation between the infill of the craters and the surrounding areas shows that the craters actually formed below sedimentary cover, in other terms correspond to sediment dissolution at depth and not erosion at the seafloor. Individual craters typically measure about 1 to 2 km in diameter and are 100 to 300 m deep. They can also be strongly elongated and at some levels coalesce to make very irregular surfaces over several hundreds of km2. Craters affect most of the Palaeocene and Eocene of the studied area, i.e. a thickness of about 1 km. The lithology of the interval is dominated by carbonates and claystones. The stratigraphic relationships with the adjacent shelf indicates that the area was already in the deep domain at the time of deposition. This rules out a formation process by continental karst for the craters. At the same time, the conical geometry is more reminiscent of pockmarks or conical injections than of collapsed karsts. Recently published work in the Gulf of Guinea has evidenced seafloor craters associated with the progressive dissolution of gas hydrates, with sizes comparable to what is observed in the NW shelf area. The complex seismic morphology observed in the Tertiary of the studied area is therefore tentatively interpreted to reflect successive episodes of growth and dissolution / dissociation of km-scale hydrate bodies in shallow subsurface. The episodes of dissolution may be related to the pressure fluctuations associated with relative sea-level changes. Whatever the exact dissolution mechanism, this represents a significant departure from classical "erosional" models in deep water, and should be considered in presence of highly irregular reflectors to avoid erroneous conclusions about the reservoir potential of affected series for instance.

Abstract
The Frac Pack completion of multiple zones in a single wellbore can be a complex and expensive operation. Effectively performing Frac Pack treatments while still providing 100% zone selectivity can be critical to the mechanical and commercial success of the well. Conventional techniques involve completing each zone separately requiring a minimum of 2 trips per zone to perforate and install the Frac pack equipment.. Depending on the number of zones and well depth, the multiple trips required to run the completion equipment in and out of the well can account for 25 to over 60% of the time required to complete the well. Presented are the results of utilizing a new completion tool system designed to allow Frac packing of multiple zones in a single trip while providing complete zone isolation prior to and immediately after treating operations. Use of this system allows selective treatment tailored to each reservoir's individual characteristics along with the capability to selectively open or close zones as needed to optimize well production. Economic benefits of this system realized include reduced rig time, ancillary costs such as equipment mobilization, demobilization charges and standby time, rental and service charges, etc.. Depending on the number of zones being treated, well depth and rig considerations, cost savings were estimated to be between 25 C_- 50 % over conventional multi-trip completion methods. Well productivity and production capabilities are enhanced by reducing formation exposure time during the completion and providing the ability to selectively produce zones as needed. The economic advantages also allowed the completion of smaller marginal zones which may not have been economically viable with conventional completion techniques. This paper will outline the system and its operations and review results from field applications. Lessons learned as well as process improvement opportunities are also addressed.

Abstract
High noise level caused by various sources perceived by oil and gas company workers has been identified as one of the hazard. Consequently, a Hearing Conservation Program (HCP) consist of workplace noise measurement, noise dose calculation perceived by individual worker has to be properly planned and determined, Employees awareness of Noise, Audiometri testing for early detection of Noise Induce Hearing Loss (NIHL) had been performing routinely by The Health Department of TOTAL E&P INDONESIE.
Management commitment stimulated into NDD (Note De Direction) and SOP (Standard Operating Procedure) of Hearing Conservation program and the program should be equipped with accurate and comprehensive information. This information focuses on concerning overall noise level at each working position from which the noise effects on individual worker can be analyzed to support the hearing diagnostic purposes and traced back to suggest appropriate engineering modifications.
The INASyst® software (the Integrated Noise Assessment System) is used to assist The Health Department for carrying out analysis of existing as well as predicted noise conditions at each working places. It also provides some essentialal noise features such as, Noise Mapping, Noise Source Analysis, Noise Dose Calculation, HPD (Hearing Protection Device) Selection and Noise Criteria Calculation. The noise propagation model applied in the software is derived from theoretical foundations whereas the accuracy of the noise mapping is examined using the ISO 9613 part 2.
The Noise Dose calculation procedure and criteria are based on both international (i.e. OSHA and NIOSH) and national (KEPMENAKER 51/1999) standards to allow comprehensive analysis.
The noise simulation program, on the other hand, is developed to allow prior analysis to the planned alteration on noise source hence noise levels at the working places. Therefore early precaution and action plan concerning the HCP can be appropriately prepared by The Health Department.
In monitoring activity, Audiometry test is performed regularly and the result is evaluated by staff together with ENT Specialist for early detection of NIHL. In general all of the Audiometri test result were entered into database, beside to improve employees awareness related with Noise, Similar Exposure Group health talk is performed using variety tools (Playing games/ animation) by ENT Specialist with the topic Noise effect, Noise control and how to use ear protector. The program evaluation was performed by elements program inspection and also presented to the management for continues improvement.

Abstract
Musculoskeletal disorders in particular low back pain, is one of the most common occupational health problems in Total E&P Indonesie. Multiple factors including mechanical and psychosocial are among possible determinants of interest.
In order to prevent MSD, the risk factors in the workplace that contribute to the development of low back pain had been studied. Resulted 5 categories; working environment, psychosocial, bio - mechanic, occupational and socio-demographic.
This research had been conducted in eight months (June 2007- February 2008) with the permanent employee as the subject. Research conducted into two group, MSD surveillance from mechanical aspects and from psychological aspect.
Epidemiological analysis consists of three stages:Conclusion of risk factors and determinantsQuantity of risk factorEpidemiogic analysis.
The objective of the critical review is to deeply explore the risk factors, and sharing idea to manage them. MSD surveillance, prevalence studies, mechanical and psychogenic back pain, and other risk factors and predictors model, had been studied in order for problem mitigation.

RESEARCH RESULT
LBP Risk to Gender: man has better protection than woman. (OR 0,276) Working on site, has higher risk to LBP than office. (OR 7.586) Comfort working place and spatial provide better protection to LBP. (OR 0,466) Bending over midline body have significants relation to LBP's prevalens (OR 1,586) Lifting over shoulder have significant relation to LBP's prevalence (OR 1.571) Sitting position group, has higher risk to LBP. (OR 3.184)
Comparing LBP prevalence found in this rsearch with data aboved, LBP prevalence in TI are far below. This lower prevalence it may come from existing 'recovery time' betwen tasks among Total Indonesie workers.

CONCLUSIONS
The researches found that there are some existing working condition, posture, gesture, and psychological aspects as risk factor of LBP.
LBP prevalence in Total E&P Indonesie is lower (4.7%) compare to LBP prevalence in petroleum industry (22%) may come from existing 'recovery time' betwen tasks among Total Indonesie workers.
