Fracturing/pressure pumping
This paper provides an account of the design, implementation, and operational insights from an enhanced geothermal system proppant stimulation targeting a volcanic, dry rock setting with an approximately 330°C bottomhole temperature.
The paper describes a multientry multistage fracturing technology developed to enable longer laterals, increase stage counts, improve stimulation efficiencies, and derisk operations.
This work demonstrates that a carefully engineered wireline perforation strategy can address the challenges of long-interval high-pressure/high-temperature completions with large intrareservoir-pressure differentials safely and effectively.

The first delivery of shale gas in the UAE marks a major milestone toward its goal of reaching 1 Bcf/D by 2030. It also signals the expansion of hydraulic fracturing in the UAE’s conventional fields.

Groups of wells communicate, interfere, and hit each other. It is an unruly scene that can offer benefits. Three stories look at why competing fracture networks can add to the production from rock that might otherwise be missed.

The complete paper describes an experimental study performed to investigate the onset of liquid loading in a 6-in. production casing at various inclination angles.

New regulations have recently commenced with the effect that all onshore oil and gas exploration and production proposals involving hydraulic fracturing in Western Australia now will need to be referred to the Environmental Protection Authority for assessment.

When a plug gets stuck in a well, consider the cause. Often stuck fracturing tools are a warning sign of casing trouble. Companies that have investigated plug problems have been surprised by the findings.

Bringing the Heat: Aramco Field Tests High-Temperature Chemistry To Slash Tight-Gas Completion CostsSaudi 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.
-
This article addresses a means to improve hydraulic fracturing operations by measuring the perforation effectiveness on a stage-by-stage basis before the hydraulic fracturing process begins.

The complete paper describes and quantifies the stress-dependence of compaction and permeability for anisotropic rock matrices, natural fractures, and hydraulic fractures, based on comprehensive rock tests of a fractured tight reservoir.
