Monitoring Surface Displacement in Three Dimensions
After several unseasonably heavy rainstorms, a 105 hectare landslide
occurred at Trapper Coal Mine in northwest Colorado (see Fig 1). Fortunately, the area
was evacuated prior to the slide and no one was injured. In some areas, the slide displaced
ground more than 122 m.Read the complete resource

Evaluating Stimulation Effectiveness in Unconventional Gas Reservoirs (SPE 124843)
This paper presents production evaluation criteria that can be used to compare the overall stimulation effectiveness in unconventional gas reservoirs. Characterizing the “relative” conductivity of the fracture network and primary fracture are critical to evaluating stimulation performance. Read the complete resource

Successful Modelling of Post-Fracture Cleanup in a Layered Tight Gas Reservoir (SPE 122021)
The issue of filtrate cleanup in tight-gas wells following a hydraulic fracture treatment has long been a topic of discussion in the industry. At one extreme, there is the possibility of a “water block” in which filtrate fluid prevents gas production completely. Read the complete resource

How to Use and Misuse Proppant Crush Tests - Exposing the Top 10 Myths (SPE 119242)
When the American Petroleum Institute established standardized crush testing procedures in 1983 (API RP-56), the committee indicated that the test results should “provide indications of the stress level where proppant crushing is excessive and the maximum stress to which the proppant material should be subjected.” Read the complete resource

Geomechanics for Interpreting SAGD Monitoring Using Micro-Seismicity and Surface Tiltmeters (SPE 117688)
We have modeled the warm-up phase of a SAGD project using a coupled reservoir simulator and stress model. We matched the injection pressure by adjusting the reservoir permeability. A fair match between data and model was obtained.Read the complete resource

Determination of Fracture Azimuth in Palnikovskoye Field Western Siberia Using Tiltmeter Technology (Russian) (SPE 117097)
Knowing the direction or azimuth of the fracture orientation is important in development of a low permeability reservoir with horizontal wellbores. The orientation of the horizontal wellbore will determine if the hydraulic fractures are longitudinal or transverse to the wellbore. Read the complete resource

Far-Field Volumetric Distribution of Fracturing Fluids Away From an Uncemented Horizontal Liner in the Bakken Formation (SPE 115826)
The Middle Bakken member of the Bakken series in the Williston Basin is sometimes completed with horizontal open holes, or with horizontal uncemented liners. Read the complete resource
