Numerical Assessment of the Maximum Operating Pressure for SAGD Projects Considering the Effects of Anisotropy and Natural FracturesDownload
There has been an increasing awareness of the importance of caprock integrity during Steam Assisted Gravity Drainage (SAGD) operations. However, mathematical tools that have been developed for caprock integrity studies have not incorporated an important characteristic of cap shales, which is...
Numerical Assessment of the Maximum Operating Pressure for SAGD Projects by Considering the Intrinsic Shale AnisotropyDownload
This paper investigates the effect of anisotropic behavior of caprock shales on the caprock failure pressure in SAGD projects. Shales and mudstones exhibit strong anisotropy at the micro and macro scales. However, the anisotropic behavior has been neglected in the existing published works on...
Numerical Modeling of Hydraulic Fracturing in Cohesionless Sand: Validation Against Laboratory ExperimentsDownload
Summary In this paper, a new hydraulic-fracturing model is introduced for cohesionless sand, which is also applicable to weak sandstone formations with high permeability and low shear strength. Phenomena such as shear-band development and shear-enhanced permeability are of paramount importance...
This paper presents a numerical model with a new approach for analyzing the propagation of pressure waves in porous media and investigates the dynamic response of sand in relation to the attributes of pore pressure pulses. There are various instances in which dynamic phenomena can have a...
A central issue in hydraulic fracturing treatment in petroleum wells is the transport of proppant particles by the injection fluid. In this paper, we present an innovative proppant transport model in a fixed rectangular- and elliptic-shaped slots. The proposed model is an improvement to the...
Punched screen as a stand-alone screen is gaining more and more popularity in Steam Assisted Gravity Drainage (SAGD) operations. However, the literature contains limited studies for proper aperture size selection and the performance of the punched screen. This paper aims at investigating the...
Sand Rate Model and Data Processing Method for non-Instructive Ultrasonic Sand Monitoring in Flow PipelineDownload
Sand production is a critical issue during oil and gas production from sandstone reservoirs. Uncontrolled sand production not only poses the risk of well failure, but also can cause extensive damage to surface and subsurface facilities such as tubing, pumps, valves and pipelines. In recent...
Smeared Modeling of Hydraulic Fracture Using Partially Coupled Reservoir and Geomechanics SimulatorsDownload
There are aspects of the hydraulic fracturing process that remain unresolved for weakly consolidated sandstones. These issues include fracture modes and geometries for weak sandstones, and higher-than-expected fracture pressure in some field projects. The development of shear bands and the...
The quantification of fines migration in the vicinity of sand control screens in SAGD wells is of paramount importance to operating companies, who require the wells to operate under optimum conditions for a period of 10-15 years. Fines migration can lead to the plugging of pore spaces...
