fracturing fluids

Operators are turning the tide on the Lower Tertiary trend with increasingly large stimulations that are also pushing the limits of offshore technology.

The authors of this paper demonstrate that future produced-water management and scale-mineral control may need to consider the sequential exposure effect of steel, cement, and shale on fluid chemistry and mineral precipitation.

The paper provides information to engineers for selecting high-viscosity friction reducers and describes a methodology for evaluating damage potential and proppant transport.

A 6-year R&D project concludes with the completion of a technology kit designed to study how combining highly pressurized natural gas and water could be a holistic alternative to traditional hydraulic fracturing.

Saudi Aramco and university researchers are experimenting with a thermochemical fracturing fluid that aims to eliminate more than half of the pumping horsepower typically required to complete horizontal wells.

Prompted by concerns about possible leaching from phenolic novolac resin-coated proppants (RCPs) during operations, Fairmount Santrol conducted analysis that showed no leaching of free formaldehyde or free phenol from its phenolic novolac RCPs.

This paper examines the chemistry of developing seawater-based fracturing fluids using two types of polymers as gelling agents and compares results to existing fresh-water-based-fracturing-fluid data under different conditions.

This paper offers an alternative explanation for the early boundary-dominated flow related to dissolution of salt-sealed natural fractures in the shale.

Two places that illustrate the mounting challenges facing the shale business are the Bakken Shale in North Dakota, where the number of working rigs is one-third what it was a year ago, and the Fayetteville Shale in Arkansas, where there are no more working rigs.

This paper introduces a new carbon dioxide (CO2) -hybrid fracturing-fluid design that intends to improve production from ultratight reservoirs and reduces freshwater usage.
