Abstract:

Interpretation problems are commonly associated with calculating water saturation in nonhomogenous shaly sand reservoirs. Redefining petrophysical properties based on well logs in shaly sand reservoirs by using fundamental geologic attributes is an important tool in developing subsurface hydrocarbon resources. Studies of the electrical anisotropy of shaly sands have shown that the level of our understanding and our ability to correctly evaluate low resistivity and low contrast pay can be greatly improved. The model developed in this thesis is similar in form to the shaly sand Dual Water model

Abstract:

Constructed wetlands are considered an inefficient technology for long-term phosphorus (P) removal. The P retention effectiveness of subsurface wetlands can be improved by using appropriate substrates. The objectives of this study were to: (i) use sorption isotherms to estimate the P sorption capacity of the two materials, masonry sand and light weight expanded shale; (ii) describe dissolved P removal in small (2.7 m3) subsurface flow wetlands; (iii) quantify the forms of P retained by the substrates in the pilot cells; and (iv) use resulting data to assess the technical and economic feasibil

Abstract:

Fault zones can strongly affect fluid flow in the subsurface. Faults can act as (partial) barriers to flow, as conduits and as combined conduit-barrier systems. Understanding the relationship between faulting and fluid flow has many practical applications, including hydrocarbon exploration and production, mineral exploration, groundwater management, radioactive waste disposal, geothermal energy and carbon sequestration. This study is primarily focussed at the applications in the hydrocarbon industry. For hydrocarbon exploration, faults are important because they can act as long term barriers (

The thesis deals with the current trends and development of the unconventional oil and natural gas production. The main aim is to evaluate and analyze the global development of unconventional production and the influence of its growth in the last decade on the global economy and the given markets. In addition, not only the pros, but also the risks and limitations of unconventional production, are examined, e.g. economic and environmental issues. The final part focuses on the United States and the local shale boom. Based on the analysis of American unconventional production, the future of these

Test results show that soaked rock's peak and residual shear strength are less than that without soaking. However, decreasing of shear strength is not always a function of soaking duration since water can not percolate homogeneously through whole rock profile if rock is unbroken. On the contrary, decrease of shear strength continues as duration of soaking increases if rock is broken. Keywords: soaking, sand shale

However, Duong’s method overestimates future production during boundary-dominated flow. It is reasonable to combine Duong’s method and the Arps decline relations for fractured wells exhibited linear flow followed by boundary-dominated flow, because the Arps decline relation has better prediction for boundary-dominated flow. For wells that have not reached boundary-dominated flow, Wattenb

Abstract:

The principle source of heterogeneity affecting flow behavior in conventional clastic reservoirs is discontinuous, low-permeability mudstone beds and laminae (shales). Simple ‘streamline’ models have been developed which relate permeability anisotropy (kv/kh ) at the reservoir scale to shale geometry, fraction, and vertical frequency. A limitation of these models, especially for tidally-influenced reservoirs, is the lack of quantitative geologic inputs. While qualitative models exist that predict shale character in tidally-influenced environments (with the largest shales being deposited near t

Abstract:

Organic shales have become one of the greatest sources of hydrocarbon thanks to novel production techniques such as hydraulic fracturing. A successful hydraulic fracturing job, however, is dependent on several rock properties such as mineralogy and elasticity. A reliable estimation of such properties is therefore necessary to determine ideal rocks for horizontal well placement. In this study, rock types within the Eagle Ford shale that would be suitable for hydraulic fracturing are identified through interpretations of available well logs and core data.

Abstract:

In 1997, Rogner published a paper containing an estimate of the natural gas in place in unconventional reservoirs for 11 world regions. Rogner's work was assessing the unconventional gas resource base, and is now considered to be very conservative. Very little is known publicly about technically recoverable unconventional gas resource potential on a global scale. Driven by a new understanding of the size of gas shale resources in the United States, we estimated original gas in place (OGIP) and technically recoverable resource (TRR) in highly uncertain unconventional gas reservoirs, worldwide.

Abstract:

New decline curve models have been developed to overcome the boundary-dominated flow assumption of the basic Arps’ models, which restricts their application in ultra-low permeability reservoirs exhibiting long-duration transient flow regimes. However, these new decline curve analysis (DCA) methods are still based only on production rate data, relying on the assumption of stable flowing pressure. Since this stabilized state is not reached rapidly in most cases, the applicability of these methods and the reliability of their solutions may be compromised. In addition, production performance predi
