Small, Highly Conductive Fractures Near Reservoir Fluid Contacts: Application to Prudhoe Bay (SPE 24856)
The productivity increases that could be achieved by fracturing high permeability formations were limited by the fracture conductivity. Oil rate increases of 5- to 6-fold were typical with aggressive TSO treatments building up to 2000 psi net pressure. Read the complete resource

Optimization of Hydraulic Fracture Treatments in the Williams Fork Formation of the Mesaverde Group (SPE 29551)
A review of over 400 fracture treatments in the Mesaverde formation of the Piceance Basin in Colorado indicated that use of low viscosity fluids resulted in decreased production. Read the complete resource

Multi-Stage Fracture Stimulations are Making Better Wells Along the Cedar Creek Anticline (SPE 38374)
Tripled gas rates with multi-stage fracs and increased frac size in this ~1500 ft. deep reservoir. Much improved rates were observed with larger 12/20 sand, despite modeling suggesting 20/40 would be adequate. Success achieved with 10-12 ppg slugs and intentional screenouts according to interviews with authors.

Stimulation Program In High Permeability Oil Sands - Case Study (SPE 39050)
Several oilfields in southern Columbia suffered from fines migration and asphaltene deposition. Propped fracs with 20/40 CarboLite provided superior remediation to other treatments, increasing production by 2-3 fold and adding 2.7 million barrels of oil production. TSOs with high net pressure gave best production.

Infill Drilling in the Moxa Arch: A Case History of the Frontier Formation (SPE 24909)
A case history of the Moxa Arch in southwestern Wyoming details the initial development on 640 acre spacing from 1977 through 1982 and the results of subsequent infill wells drilled from 1989 to 1992. Read the complete resource

Hydraulic Fracture Performance in the Moxa Arch Frontier Formation (SPE 25918)
This paper presents a comparison of hydraulic fracture performance during the initial development of the Moxa Arch Frontier sandstone in southwestern Wyoming (1975-85) through infill development in 1989-91 (320 acre spacing) and
1992 (160 acre spacing).Read the complete resource

Massive Hydraulic Fracturing Unlocks Deep Tight Gas Reserves in India (SPE 107337)
Tight gas fracturing was pioneered in North America in the 1970’s and 1980’s, and also has a relatively long history in Germany. In the rest of the world, however, massive fracturing for production from tight gas formations (i.e. k < 0.1 mD) has been very rare, due mainly to poor economics, rather than lack of opportunities.

Development and Testing of a Pseudo-Three-Dimensional Model of Hydraulic Fracture Geometry (SPE 10505)
A pseudo-three-dimensional (P3DH) model has been developed to realistically describe the evolution of geometry of a 3-D hydraulic fracture produced by fluid injection into a reservoir. Read the complete resource
