Acidizing/stimulation
This paper highlights an approach of using active hydrogen to stimulate hard-to-recover formations from candidate-well selection through pilot execution and evaluation.
The objective of this study is to use expired medications as green corrosion inhibitors that can be used during stimulation treatments. Because the medications are expired and not fit for human consumption, the cost is inherently low.
This paper describes the stimulation of a horizontal water-injection well with a limited-entry-liner completion in an onshore carbonate reservoir using a large volume of viscoelastic diverter-acid fluid system ahead of the main acid stage.

Seismic stimulation, achievable with the implementation of a single tool, requires significantly lower investments than gas, thermal, and chemical injection methods, with minimal environmental impact. -
This paper describes an experimental study with a new propellant and aims to understand the pattern of fracture creation with these propellants.
-
The evolution of horizontal drilling and multistage completions has changed matrix stimulation from the “more acid, better result” belief to effective lateral distribution and deeper penetration with less acid.
-
Fluids introduced into a reservoir for stimulation typically take the path of least resistance and, therefore, frequently go into areas with open flow paths. In many cases, those areas are not the targets of stimulation.

This paper presents the planning and execution of a matrix-stimulation pilot project in the heavy-oil Chichimene Field in Colombia.

Cyclic steam stimulation (CSS) is one of the principal enhanced-oil-recovery methods for heavy oil. CSS was performed in some of the wells of a heavy-oil field in Kuwait. Multiple cycles were applied in these wells. However, the total water produced in each cycle was much less than expected.

The treatment in a deepwater, frac-packed well with fiber-optic-equipped coiled tubing (CT) and a rotating, hydraulic high-pressure jetting tool achieved successful stimulation of a 500-ft-long frac-packed zone after several previous failures using different techniques.
-
This paper discusses a novel approach to abrasive perforating, including the first-ever use of an acid-soluble abrasive material and ending with CT-jetting-assisted nitrified stimulation.
-
This paper describes the testing of a novel concept based on resistivity measurements to monitor acid-stimulation operations.
