The application of learnings from an underground laboratory has led to significant
completion changes in a world-class North American unconventional asset. Understanding …

Hydraulic fracturing is an important means to develop unconventional resources. Fracture
diagnosis techniques have been emerged in recent years, which can evaluate hydraulic …

Hydraulic fracturing technology is an important technique for developing tight oil and gas
resources. Multicluster fracture diagnosis is significant for hydraulic fracture design and …

Water hammer is oscillatory pressure behavior in a wellbore resulting from the inertial effect
of flowing fluid being subjected to an abrupt change in velocity. It is commonly observed at …

The water hammer wave diagnostic method is a new promising fracture diagnostic method
that can determine the fracture location underground. The key to this technology is the …

Hydraulic fracturing has revolutionized shale oil/gas production in the last decades, but
further robust understanding is needed as to what happens during fracture placement. At the …

A pressure pulse, known as a water hammer, can occur immediately after water-injection
wells are shut-in for emergency or operational reasons. Large pressure pulses may cause …

The implementation of a low-frequency electromagnetic induction tool for propped-fracture
detection and diagnostics requires in-depth examination of the reliability and accuracy of the …

The efficiency of a hydraulic fracture treatment depends primarily on the dimensions and
orientation of propped fractures. We have developed a novel electrode-based resistivity tool …

A tool concept using downhole electrical measurements for mapping electrically conductive
proppant in hydraulic fractures is presented in this paper. The method relies on direct …
