Optimization of Multiple Hydraulically Fractured Horizontal Wells in Unconventional Gas Reservoirs

Figure 5: Two scenarios of multiple horizontal well placement.

This paper demonstrates the accuracy of numerical modeling of multistage hydraulic fractures for actual Barnett Shale production data by considering the gas desorption effect. Six uncertain parameters, such as permeability, porosity, fracture spacing, fracture half-length, fracture conductivity, and distance between two neighboring wells with a reasonable range based on Barnett

Numerical simulation study on miscible EOR techniques for improving oil recovery in shale oil reservoirs

Fig. 15 Effect of the injected gas on oil viscosity (molar diffusion mechanism is OFF). a Natural gas, b CO2

Firstly, numerical simulation methods of compositional models have been incorporated with local grid refinement of hydraulic fractures to mimic the performance of these miscible gases in shale reservoirs conditions. Implementation of a molecular diffusion model in the LS-LR-DK (logarithmically spaced, locally refined, and dual permeability) model has been also conducted.

Improved Water Use Estimates for Drilling and Hydrualic Fracturing in Northeastern Colorado

The development of unconventional resources in tight shales has stimulated considerable growth of oil and gas production in Northeastern Colorado, but has led to concerns about added demands on the region’s strained water resources. Northeastern Colorado’s semi-arid environment, population growth, competing water demands and uncertainty about drilling and hydraulic fracturing water requirements have resulted in scrutiny and conflict surrounding water use for tight shales. This study collects water use data from wells in Northeastern Colorado to improve water estimates and to better understand important contributing factors.

This study shows that the number of hydraulic fracturing stages is a better measure of the future water demands for horizontal wells. Vertical wells use significantly less water than horizontal wells and will be less prevalent in the future. Introduction Water resources in Northeastern Colorado and the western United States are constantly

Comparative Study and Analysis of the Development of Shale Gas between China and the USA

Production Decline Curves of Tight Oil Wells in Eagle Ford Shale

This study derives typical production curves of tight oil wells based on monthly production data from multiple horizontal Eagle Ford shale oil wells.

  Abstract This study derives typical production curves of tight oil wells based on monthly production data from multiple horizontal Eagle Ford shale oil wells. Well properties initial production (IP) rate and production decline rate were documented, and estimated ultimate recovery (EUR) was calculated using two empirical production decline curve models, the

Geological characteristics and ‘‘sweet area’’ evaluation for tight oil

Tight oil has become the focus in exploration and development of unconventional oil in the world, especially in North America and China. In North America, there has been intensive exploration for tight oil in marine. In China, commercial exploration for tight oil in continental sediments is now steadily underway. With the discovery of China’s first tight oil field—Xin’anbian Oilfield in the Ordos Basin, tight oil has been integrated officially into the category for reserves evaluation.

Microseismic Imaging of Hydraulically Induced-Fractures in Gas Reservoirs: A Case Study in Barnett Shale Gas Reservoir, Texas, USA

Microseismic technology has been proven to be a practical approach for in-situ monitoring of fracture growth during hydraulic fracture stimulations. Microseismic monitoring has rapidly evolved in acquisition methodology, data processing, and in this paper, we evaluate the progression of this technology with emphasis on their applications in Barnett shale gas reservoir.
