Hydrajet fracturing, which can place multiple propped hydraulic fractures in precise locations, effectively stimulated two underperforming horizontal openhole gas wells in the low-permeability ...

Shale oil reservoirs are usually developed by horizontal wells completed with multi-stage hydraulic fractures. The fracture interference between clusters in a single stage and between consecutive ...

Based on their research, researchers said it takes, on average, between 2.6 million and 9.7 million gallons of water to fracture a well in the region.

In hydraulically fractured wells, drilled in unconventional reserves, transient linear flow (TLF) is the dominant flow regime. Consequently, a rate transient analysis (RTA) technique called TLF ...

US researchers have proposed the use of hydraulically fractured oil and gas wells to store renewable energy via compressed natural gas, with the levelized cost of storage potentially coming in at ...

It also meets API TR 5SF protocols for testing connection performance in multi-fractured horizontal wells. Currently available in 4.500- to 7.625-in. sizes, WLHT has a semi-flush OD and pin nose ...

Low and ultra-low permeability sandstones account for much of the increase in gas reserves in China. Effectively developing these reservoirs has been a research focus in the region. Low and ultra ...
