Corrosion Inhibition of Benzyl Quinoline Chloride Derivative-Based Formulation for Acidizing Process
Development and implementation of a more effective and environmentally friendly acidizing corrosion inhibitor derived from benzyl quinoline chloride to mitigate rapid corrosion of metal-based drilling equipment.
The Research Council of Norway’s $118,000 grant will support development of longer fishbone laterals to raise production while lowering carbon footprints.
This paper describes an effort to use multiple technologies to better understand an Arkoma Basin reservoir and the interdisciplinary relationship between the reservoir’s subsurface hazards and a stimulation treatment.

To improve the productivity index of a well in a carbonate reservoir offshore Abu Dhabi, a multilateral acid-jetting technology was adopted as a more-effective alternative to typical drainage methods.

It is pleasantly surprising to find a revival in sandstone acidizing. For many years, sandstone acidizing was becoming almost a lost art, overshadowed by carbonate acidizing and hydraulic fracturing.
-
The authors describe a self-breaking, formation-damage-free, novel nanoparticle-based gelled-acid system to replace polymer-based gelled-acid systems.
-
The authors describe the benefits of a single-phase retarded inorganic acid system, which they write features the same benefits as emulsified acids while eliminating the drawbacks of the latter.
-
This paper presents a novel sandstone-stimulation technique using thermochemical fluids.

Carbonate reservoirs require effective acid stimulation to improve well productivity. For long horizontal wells, a complicating factor has previously been the difficulty of controlling acid placement along the reservoir section. The Smart Liner concept uses a number of small holes spaced in such a way so as to distribute the acid evenly along the reservoir interval.

HCl acid stimulation of carbonate production requires the retardation of the HCl-carbonate rock reaction to achieve the optimum balance between total fluid used and the enhancement of well production. The described investigation was done offshore Sarawak using Indiana Limestone cores.
-
Flow rate is a major challenge for geothermal. However, the techniques used in shale to prevent flow localization can be applied directly to geothermal. If we can create hundreds or thousands of flowing fracture pathways around a horizontal or deviated geothermal well, then we will have truly “changed the game.”
-
The implementation of fishbone stimulation helped to more than double estimated well productivity and tripled the production rate in a tight carbonate reservoir well compared with conventional stimulation during initial testing.

The authors describe a carbonate reservoir stimulation technique able to deploy acids in the rock far away from the wellbore through mechanically drilled holes with known depths and azimuths.
