Fracturing/pressure pumping
Output is rising fast in the South American shale play and putting Argentina on a course to soon reach 1 million B/D.
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Skipping one traditional step in the supply chain might save oil and gas companies hundreds of millions of dollars a year while making a meaningful dent in emissions. -
A Canadian company reports that it has drilled and completed a historic horizontal well in Saskatchewan.

Electrically powered completions equipment takes another step toward greater sector adoption with the announcement of this new agreement.

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.
-
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.

The complete paper presents a strategy for selecting a surfactant/solvent package for parent wells. Oil recovery and associated water saturation in the microfluidic-based device, with or without surfactant, are quantified and reveal that the oil recovery is enhanced with surfactant.
