Acidizing/stimulation
This study explores enhancing gas production through a novel combination of prestimulation using a coiled tubing unit and high-rate matrix acidizing.
In this work, microseismic observations are integrated with strain and other observations to investigate the microseismic response in relation to the underlying hydraulic fracture geometry for different rock types.
This year’s Acidizing feature presents three SPE conference papers that discuss an important battlefront of enhanced production—carbonate reservoirs, those plays whose heterogeneity, reactivity, and flow behavior pose challenges that remain comparatively little-understood, despite the industry’s intensified efforts to maximize their output.

The authors of this paper describe a project in which far-field diverters were pumped to mitigate wellbore sanding and production loss in existing parent wells. -
Engineers desperately need an alternative to acid placement through pipe, coiled tubing, or bullheading. For example, propellants have been around for years; however, their performance has not quite met the hype. Nevertheless, several case histories have been authored to suggest their efficacy; historically, some treatments have even been wildly successful.

The first acid job dates to 1895. Challenges remain, however, when it comes to lithology, coverage, penetration, and management of reaction products. These themes remain a focus for stimulation engineers.
