Fault Detection Workflow in Al Khalij Field in Qatar
Authors B. Klein, B. Gauthier, J. McCallum and M. EmangIn Al Khalij carbonate field, the impact of faulting and fracturing has long been considered insignificant on the dynamic
reservoir behaviour. However with the continued field depletion, an interference between some wells has been noticed. This
interference cannot be explained by matrix properties. Therefore, a better understanding of the detailed structure grain seems
to be the key for understanding the field dynamic behaviour. This integrated study shows that faults can barely described
from the seismic data. But it has been found that a detailed understanding of the field structure is possible if other data are
also taken into account.

Qatar Photochemical Modelling Platform: A New Tool to Optimize Air Pollution Control for the Oil and Gas Industries
Authors A.H. Al-Mulla, A.F.M. Ahmed and D. LecoeurDuring recent history, Qatar and other Gulf States, witnessed a phenomenal economic and
industrial growth that led to an increase in air pollution emissions including precursors responsible
for ozone formation (NOx and VOCs). Consequently the level of ambient air ozone observed in a
number of countries in the region, including Qatar, has significantly increased over the national
limits.

Hydraulic Fracturing Using Heavy Brine and Microseismic Monitoring in Yufutsu Oil and Gas Field
Authors R. Kamitsuji, K. Nagai, Y. Matsuno, Y. Ohsaki, T. Tamagawa and K. TezukaHydraulic fracturing using heavy brine was conducted to stimulate the deeper part of the completion interval in the naturally
fractured reservoir, Yufutsu Japan. The microseismic monitoring and the temperature surveys showed that the deeper part was
stimulated effectively as expected.

Method and Apparatus for Simultaneous Stimulation of Multi-Well Pads
Authors R.C. Tolman, J.W. Simons, D.H. Petrie, K.J. Nygaard, S.R. Clingman and A.M. FarahProgressively, the oil and gas industry is producing from unconventional reservoirs with low permeability in numerous small
pay zones that require close well spacing and multiple stimulations in each well. To effectively produce from such reservoirs
and reduce the surface footprint, ExxonMobil has drilled multiple wells from single pads, and new technologies have been
developed to efficiently stimulate the multiple pay zones in each well.

Full-Field Development Plan “The Big Picture—Creating the Future from the Future and Success through Real Synergy”
Authors H.H. Hafez, M.M. Kenawy, A. Al-Saiid Keshka, K.A. Samad, S. Al-Bakr and S. Al-DhiyebiThis paper represents a case history of a full-field development
plan for one of the major fields (field "A") in Abu Dhabi
Company for Onshore Oil Operations (ADCO-UAE)
consisting of three different reservoirs. Field (A) development
is becoming increasingly complex and expensive as this field
acts as a hub for another two producing fields and several
undeveloped fields. This involves developing an efficient
design and planning philosophy. Best practices in integrating
new technologies in materials, construction, operations as well
as management techniques including the right team to really be
successful are all part of the "big picture".

Identification and Characterization of Producing Fractures in Naturally Fractured Reservoirs Using PIWD
Authors A. Berkat, K.l Kartobi, M.M. Cherif, H. Qutob and N. BarakatEarly recognition of a fractured reservoir and an estimation of its rock characteristics, such as porosity and permeability, will
influence the location and number of subsequent development wells and, therefore, is of major economic significance on the
future development of the field.

Modeling the Effect of Asphaltene on the Development of the Marrat Field
Authors T. Yi, A. Fadili, M. Ibrahim and B.S. Al-MatarThis paper describes the study of the effect of asphaltene precipitation and deposition on the development of the Marrat field
using a compositional simulation model with asphaltene modeling facilities.The model enables the simulation of asphaltene
precipitation, flocculation, and deposition including adsorption, plugging, and entrainment, and the resulting reduction in
porosity and permeability and changes in oil viscosity and rock wettability. A workflow was established in the study to i)
characterize the equation of state (EOS) by analyzing the fluid PVT and asphaltene data from the lab; ii) calibrate the
asphaltene model input parameters using the core flood experimental data; and iii) incorporate the EOS and the asphaltene
parameters into the full field simulation model.

Combination of Chemical Diverters and Degradable Fiber Technology Enhances the Success of Stimulation in Complex Carbonate Environments
Authors Q. Dashti, H. Liu, T. Cirrincione, M. Al-Saqabi, T.M. Lesko and A.A. MajidDue to damage caused by drilling and completion operations, most wells in the Jurassic carbonate reservoirs in North Kuwait
require acid stimulation after perforating to either recover or enhance the well productivity. To date, production responses
after stimulation treatments have been mixed, depending on the formation, the type of treatment and the volume and the
chemistry of stimulation fluids. Additionally post-stimulation production logging surveys in many wells typically have
shown poor stimulation efficiency with only a short perforation interval contributing to a majority of the production.

Improving Drilling Efficiency Through Wellbore Stability Analysis in the Gulf of Suez, Egypt
Authors M. Van Steene, D.J. Dutta and A.A. El FotohAn increasing number of deviated wells are being drilled to maximize production and hydrocarbon recovery in the mature
reservoirs of the Gulf of Suez (GoS). Successfully drilling a high-angle well in a tectonically disturbed and structurally
complex area like the GoS is very challenging, especially in depleted reservoirs. Selecting the optimal mud weight is
absolutely essential. Stress orientation and magnitude also have a major impact on wellbore stability.

Recovery Behaviour Of A Partly Illitized Sandstone Gas Reservoir
By A.O. UwagaDiagenesis is defined as any chemical, physical or
biological change undergone by a sediment (rock)
after its initial deposition and during and after its
lithification, exclusive of surface alteration
(weathering) and metamorphism. The diagenetic
changes that occur in the rock result in the
alteration of some of the original petrophysical
properties of the rock. Porosity and permeability,
amongst others, have been established to be
altered by diagenesis.
