Effective Permeability 3D Model Unlock the Uncertainty Production in Low Perm Fluvial-deltaic Reservoirs, Nilam Field, Kutai Basin, Indonesia
Authors Jose Benito Corbellini, Ratno Adi, I Made Sutha, Luhut Gultom, D. Hazman and Amireno SoenoroNilam Field is located in Kutai Basin, East Kalimantan, Indonesia, which even more than 40 years of exploitation, these fluvial
deltaic reservoirs, of age Early-Middle Miocene, still have significant reserves of gas, that occur in poor quality reservoir rocks
in structural, stratigraphic or combination traps, that were not entirely examined. This case history describes some works
carried out in this field over these low permeability reservoirs, locally known as G's sandstones, in order to understand the root
of the erratic production results, evaluate the formation damage, identify the potential areas and present the right solution for
recovering the undeveloped accumulations.

Reducing Safety Incidents While Lifting and Handling Drilling Jars: A Case Study
Authors Chad D. Evans, P.E. Rienk Reitsma and Euan RamsayThe handling of drilling jars can present safety hazards when they are being serviced, transported, loaded or
unloaded, handled on the rig floor, run in hole or racked in the derrick. Dangers are especially prevalent if the drilling jar is
not equipped with a mechanical locking device. These tools present a potential hazard to personnel because of the possibility
of inadvertently activating the jar.

Hydrogen Imbalance in Petroleum Source
More LessThe average molar hydrogen concentration relative to carbon is always higher in petroleum than the source organic matter
and thus it becomes a serious concern for the theory of organic origin. On the other hand, abiogenic theory of petroleum
generation do not have this problem because hydrogen is available even deep inside the earth either due to serpentinization or
by chemical reactions of freshly cut ferromagnesian mineral surface with water.

Inferring Reservoir Interwell Dynamic Connectivity Based On Signal Processing Method
Authors Jian Hou, Zhenquan Li, Yejun Liu, Yanhui Zhang, Chuanfei Wang and Fuquan LuoA reservoir can be considered as a complete system, which includes injectors, producers and the flow channels between them.
Injection rate is a stimulus of the system while produced rate is a response. However, there are time lag and attenuation
occurring between stimulus and response, because of the influence of reservoir porous media.

Exploiting the Synergies by Combining Multilateral Well Intervention Techniques with Real Time Downhole Measurements - Lessons Learned from Trilateral Horizontal Well Stimulation in the Partitioned Zone
Authors Jamal Al-Rubaiyea, Adel Attiea, Fahad S. Al-Hadyani, Ikhsan Nugraha and Zafer ErkolMultilateral wells pose a unique challenge to operators when planning for any intervention. Correctly accessing and
uniformly acidizing all laterals continues to be chall enging. While lack of reli able downhole data and knowl edge
about naturally fractured zones or po or correlation between porosity and permeability in carbonates limit the
effectiveness of a stimulation treatment; sometimes the inability to access all laterals even prevents the lateral from
being acidized at all. These limitations in acidizing, therefore, provide lower than expected gains.

Implementation of Next Generation Intelligent Downhole Production Control in Multiple Dipping Sandstones Reservoirs, Offshore East Malaysia
The ‘S’ field, located offshore East Malaysia, consists of multiple-dipping heterogeneous sandstone reservoirs with
unconsolidated formation. These multi-stacked reservoirs have an overall 40m thick oil column with marginal Oil-Initial-In-
Place (OIIP). A large gas cap, i.e. twice the OIIP equivalent, also exists. Scenarios of zonal gas-out leaving huge oil bypass
and moderate aquifer strength with inevitable water invasion cautioned the asset team to consider intelligent zonal flow
control especially in its horizontal producing wells.

Performance Evaluation And Mechanism Analysis Of HPAM Solution With Broad-distribution Relative Molecular Mass
Authors Xiangguo Lu, Huanjun Liu, Shuxia Wang and Xiaoyan WangBroad distribution relative molecular weight HPAM (“B-HPAM” for short) was produced by mixing with three kinds of
different HPAM at different weight ratios, whose viscosity-average molecular weight were 19×106, 25×106, 35×106,
respectively. During the chemical flooding stage, the small flow resistance in high permeability formation led the HPAM
solution to flow through easily. Firstly the larger polymer clews absorbed in the larger pore throat and then the smaller clews
absorbed in the smaller pore throat. Enlarged the swept volume and enhanced oil recovery. Therefore, it was a promising
profile control method.

Multi-Azimuth, Coil Shooting And Dual Sensor Streamer Acquisition: Step Change Seismic Imaging Results In Deep Water Indonesia
Authors M. Buia, E. Tozzi, A. Ravasio and P. BrownWhile wide-azimuth seismic surveys represent a routine in land environments, in marine environments things go differently.
Conventional offshore 3D acquisition is still being performed mainly using narrow azimuth streamer configurations, even in
structurally complex areas. Attempts at breaking this paradigm have been recently made by the industry with good results,
through the acquisition of some unconventional “Multi Azimuth” (MAZ), “Wide Azimuth” (WAZ), “Rich Azimuth” (RAZ)
and Coil Shooting marine surveys. Here we are presenting planning, acquisition and processing results of the advanced marine
surveys, a Multi-Azimuth and a Coil shooting (Full azimuth), recently acquired by Eni e&p in Indonesia. We are also
presenting a 2D test and successive 3D acquisition of a broad bandwidth (dual sensor) seismic in West Timor area, aimed at
exploiting sub thrust geology. At the end we demonstrate that advanced acquisition techniques effectively provide improved
geophysical images and more geological insight for exploration compared to traditional techniques.

Reservoir Fluid Sampling of a Wide Spectrum of Fluid Types Under Different Conditions: Issues, Challenges, and Solutions
More LessReservoir fluid PVT is the basis for efficient reservoir development plans, appropriate facilities, and plant design and
operation and plays a vital role throughout the production life of the reservoir. Acquisition of representative high quality insitu
reservoir fluid samples is the first step in this process and requires special attention. The challenges of acquiring
representative samples depend on a number of factors, including the type of the fluid being sampled, the initial reservoir
conditions, and the formation properties.

The Socioeconomic Repercussions of Achieving Energy Independence
By L.A. AlcoserThis paper presents an innovative technique for the analysis and evaluation of the benefit realized to a country’s economy
based on achieving energy independence. Noble Energy has recently discovered and is currently developing a substantial
natural gas find located offshore Israel. Israel has previously had no petroleum presence and has had to solely rely on energy
rich neighbors for energy. Noble Energy’s find and subsequent development is of such magnitude that Israel is poised to
transition directly from entirely energy dependent to energy independent.

Evaluation of Time-Domain Controlled-Source Electromagnetic Method for Detecting Hydrocarbon Targets in East Malaysia Environment
The time-domain Controlled Sou rce Electromagnetic (tCSEM) method is emerging as a practical tool fo r oil an d
gas exploration on land and shallow marine environments (Wright et al., 2 002; Ziolkowski et al., 2 007). In
particular, it can overcome the airwave interference problem faced by frequency-domain CSEM method in shallow
water (Weiss, 2007).

A New Method to Identify Proppant Location in Induced Fractures
Authors Robert J. Duenckel, Harry D. Smith Jr., JiangPing Hao, DaKang Gao, Terry Palisch and Xiaogang HanA new technique is discussed and tested in this work for proppant placement determination. A high thermal neutron capture
compound (HTNCC) is inseparably incorporated into a ceramic proppant during manufacturing in sufficiently low
concentration that it does not affect proppant properties. Proppant is detected using standard compensated neutron tools or
pulsed neutron tools, with detection based on the high thermal neutron absorptive properties of the compound relative to
downhole constituents. Compared to the traditional radioactive tracer (RA) techniques, the new detectable proppant is not
radioactive so there are no HSE or regulatory issues. Additionally, since the high thermal neutron absorbing compound is
placed in the proppant during the process of manufacturing, there is no requirement for special handling or mixing processes
at the well site.

Development and Performance of an Eco-Friendly Cross-Linked Polymer System for Water Shut-Off Technique
Authors Baisali Sengupta and V.P.Sharma and G. UdayabhanuExcessive water production is a serious issue to be dealt with during oil production from reservoirs. The use of gel as the
water shutoff agent has been widely reported in enhanced oil recovery (EOR) for the development of mature oil fields.
Polymer gels are used successfully in many reservoirs all over the world, but the problem lies in finding the suitable and
economical polymer for the harsh reservoir conditions of high temperatures and salinity.

Growth and Demise of Neogene Central Vietnamese Carbonate Platforms: The Effect of South China Sea-Opening and Onshore Uplift
Authors Michael B. Fyhn, Lars H. Nielsen and Henrik I. PetersenNeogene carbonate platforms cover as much as 70,000 km2 of the central Vietnamese South China Sea margin.
The margin is little explored, and so far, exploration has focussed on Miocene carbonates with a number of oil and
gas discoveries made. Carbonate growth initiated during the Early Miocene following Eocene-Oligocene
continental rifting. Early carbonate deposition took place on two regional platforms separated by a narrow
depression that marks the trail of the East Vietnamese Boundary Fault Zone (EVBFZ).
