Formation damage
This paper describes the success of using a new low-equivalent-circulating-density organophilic clay-free inverted emulsion fluid in gas reservoirs at elevated temperatures and with differential pressures up to 4,500 psi.
While the ongoing technical studies and technology developments in the area of formation damage are heavily focused on key damage-mechanism scenarios during drilling and production, such as drilling-fluid-induced damage, scaling, clay swelling, fines migration, and incompatibility of fluid/fluid and fluid/rock in conventional sandstone and carbonate reservoirs, there …
The authors of this paper present results of a study that examined formation-damage mechanisms caused by drilling fluids in tight reservoirs in onshore oil fields in Abu Dhabi.

The authors of this paper present a laboratory-based model to determine the detachment of authigenic and detrital particles in formation damage. -
The authors of this paper discuss a biosurfactant treatment that offers an economical method for remediation of formation damage caused by high-molecular-weight paraffin wax deposition in porous media.

This paper highlights a tailored chemical treatment strategy developed for solids mitigation for a Delaware Basin operator.

The paper provides information to engineers for selecting high-viscosity friction reducers and describes a methodology for evaluating damage potential and proppant transport.

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.

The adage “prevention is better than cure” is the first thing we consider regarding formation damage, but how prepared we are for the treatment and cure to allow a well to perform to its full productivity or injectivity potential? And how can digital tools be an effective enabler?

This paper presents a novel sandstone-stimulation technique using thermochemical fluids.

The obsession with better hydraulic fracturing has steadily pushed on shale production in year one, but the decline remains steep. Chemistry could help explain, and perhaps extend, the short productive life of these wells.

The authors of this paper propose a new chemical treatment for efficient remediation of water- or hydrocarbon-phase-trapping damage in low-permeability porous media.

Laboratory formation damage testing is often used to help select optimal drilling and completion fluids, but predicting the overall effect of formation damage on well performance requires further interpretation. Paper SPE 199268 presents a case for use of CFD to upscale laboratory data to quantify that effect.
