Tapping Shale Resources: An Emerging Exploration Concept in Kuwait
By R. HusainThe state of Kuwait is endowed with prolific hydrocarbon resources occurring over a wide range of stratigraphic spectrum. While conventional exploration for oil and gas in the country has kept pace with the global efforts, unconventional resources, particularly shale gas and oil are yet to find a place in the country’s energy basket. The paper details the shale resource potential of Kuwait and unconventional workflows to identify sweet spots for future exploration.

Seismic for Unconventionals Technique Defines Sweet Spots in Shales
By M.S. EganSeismic for Unconventionals is an integrated workflow that includes seismic, log and core data and specialized data analysis, providing early understanding of the varying conditions of reservoir quality and completion quality across a field that define sweetspots versus poor areas.

The Silurian Shale Gas Potential of Turkey
By Ş. ŞenThe Silurian formations in the Western Pontide contain 1120 m thick siltstone-sandstone, limestone and black shale. The siltstone-sandstone-limestone to shale ratio ranges from 1:2 to 1:3. The shales have a fair to good source rock potential because TOC content is ranging from 0.18 to 1.72 %. Organic matter type is type III. Tmax values were measured between 452 and 487 °C. The Silurian shales contain 42-47% quartz, 17-51 calcite and 3-42% clay. Therefore, the Western Pontide Silurian shales have shale gas potential. The Silurian formations in the Eastern Tauride consist of a nearly 200 m thick sandstone, limestone and black shale. The sandstone-limestone to shale ratio ranges from 1:2 to 1:3. The shales have fair to good source rock potential because TOC content is ranging from 0.18 to 1.95 %. The Silurian shales are represented by overmature organic matter. Thus, the Eastern Touride shales have probably limited shale gas potential although fair to good source rock potential and suitable mineralogical content. The Silurian shales of the SE Anatolia have a good to excellent source rock potential because TOC content is ranging from 0.4 to 17%. However, the shales have a restricted shale gas potential because the source rocks generally fall into the oil generation zone.

Shale Gas in West of Iran
By N. AhmadiAll field geological observation and subsurface evidences collected from deep drilled wells in west of Iran (Kermanshah province). Also, geological, geochemical and gas chromatographic studies while drilling in Nowsoud irrigation tunnel throughout Upper Cretaceous rocks confirms availability of large valume of shale gas in mentioned area.

Application of Combined Cuttings Gas/Oil Analysis, Rapid XRF and High Resolution Photography to Evaluation of Unconventional Reservoirs
By D.L. HallExploration and exploitation of increasingly complex reservoirs, along with technical challenges associated with optimizing horizontal wells into tight or unconventional pay sections benefits from new approaches involving additional data collected in a cost effective and time effective manner. Herein we describe one such methodology applicable to samples that are historically viewed as being of limited value, namely, unpreserved cuttings. The rock is photographed under visible and UV light, crushed and analyzed for included hydrocarbon and non-hydrocarbon species with a sensitive mass spectrometry system, and finally probed for its elemental composition with a customized XRF analyzer.

The Evolution of Optimization in the Barnett Shale
By J. OttmanThe Fort Worth Basin in north Texas covers approximately 34 million acres. Along its eastern flank, 2 million acres have been defined as the Barnett core play area. ExxonMobil's affiliate, XTO Energy, develops and manages approximately 235,000 acres throughout this core region. As one of the first shale gas plays to begin a large scale development, initial industry practices in the Barnett were often guided by uncalibrated conventional assumptions that hindered cost effective depletion programs.

International Shale Gas Partnership: China Sichuan Shale Gas Project Case Study
By N. FeastThere is growing international interest in shale gas development, due to the recent advances in technology and operating practices which are unlocking large shale gas resources across North America and changing the energy outlook. China is estimated to have similar resource potential and, given the large and growing energy demand and existing gas infrastructure, several evaluation projects have been initiated.

Global Trends and Local Challenges Reshaping Shale Gas Development Strategies
By C. FeddIn less than a decade, the petroleum industry has experienced significant change associated with the development of shale gas reservoirs. Integration of technologies such as horizontal wells and multistage fracturing has enabled much greater reservoir contact, and the industry has been effective in porting these technologies around the world. It has also become recognized that a reservoir-centric approach with an integrated team of multidisciplinary experts is required to optimize the overall drilling, completion, and stimulation design, as reservoir characteristics vary from shale basin to shale basin. And, additional local challenges are playing a role, as shale gas development is also influenced by local resource constraints, logistical challenges, and market drivers. These local challenges can play a significant role in defining the optimum development strategy, especially given the sheer volume of proppant, water, chemicals, and trucks typically required to support shale gas operations. Although the specific local challenges may be different, the industry is moving in a consistent direction to improve efficiency and increase production with fewer resources and less waste. This presentation will provide a snapshot of how global trends in shale gas are accelerating the learning curve around the world and, at the same time, how reservoir conditions and local constraints are reshaping the development of basin specific solutions. It is through the right mix of global solutions and local customizations that basin specific solutions will reshape shale gas development strategies in the years to come.
