“…Fines aresmall particles with diameter ranging from 0.1 to 30 microns. With increased intergranural distance it is more likely for fi nes to infl ux the well, which will cause stress redistribution and reservoir failure in the future (Christianti, 2011 (Gruesbeck, 1982). As in the case of the formation of arched structures, brief reversal of fl ow after continuous production causes re-establishment of original permeability, then resulting in decline in permeability again.…”

In the studies made by Schlum (Musaed, 1999) berger they used to inject this agent with water into the near wellbore zone, but there is no point whether it is injected separately or as an additive to the injection water, thus distributing this agent in the reservoir.…”

Oil production from weakly consolidated sandstone wasn't needed for decades, but as the time goes on, traditional oil reserves deplete and possibility of these reserves being produced is growing up. In the case of high viscosity oil, located in such reservoir, problem gets even worse. Traditional sand control methods cause lower production rates, thus, making production not profi table enough. In the industry there was need for new approach and it appearedsand management. Sand management is a risky business, but it allows some reservoirs to be produced with good enough profi t. But with right amount of preparations risk can be minimized and production becomes more likely. One of the most promising instruments of sand management is chemical treatment with UTTA. It allows to sand particles and fi nes to be held in the reservoir so they won't cause so much erosion and won't plug pore throats and fi ltration channels.

“…Other methods of fines migration control or prevention notably include organosilanes (Kalfayan 1990), Surface Modification Agent for coating proppant (Nguyen 1998), Zeta Potential Altering System (Kakadjian 2007) and nanoparticles (Belcher 2010). Other fines control agent techniques have also been disclosed (Christianti 2011). Clay damage remediation may be achieved using hydrofluoric acid (HF) to dissolve siliceous material or by fracturing past the wellbore damage area.…”

Making Clays Water Resistant: New Technology That Minimizes Formation Damage

et al. 2015

Formation damage and the resultant reduction in hydrocarbon production rates due to clay expansion are long-recognized problems (Ohen, 1991). The clay damage may occur during the drilling, completion and production phases of well operations. Often the remediation of clay damage is inadequate, providing only temporary improvements in hydrocarbon production. The prevention of clay expansion presents a challenge; fit-for-purpose chemistries exist, and are a function of clay identity and operational phase of the well.Two broad subsets of clay damage mechanisms are chemical and mechanical considerations (Bennion, 2002). The focus of this study is to evaluate the minimization of clay hydration by coating clays to prevent chemical or reactive damage. An example of chemically induced formation damage would be clay swelling. On exposure to introduced aqueous fluids, other than interstitial water, sensitive clays will hydrate detrimentally. The end result can be subsequent hydrocarbon flow restrictions due to a decrease in pore space and detrimental formation softening allowing embedment of proppant. Chemical methods of ameliorating clay expandability potential fall into two broad categories: temporary and permanent stabilizers. The temporary clay control additives prevent clay swelling by increasing the ionic strength of treatment fluids, e.g., potassium chloride. Permanent clay stabilizers create a protective sheath around the clay.The formation of a self-assembled monolayer (SAM), where the chemical covalently bonds to the siliceous formation surface, offers a more robust chemical coating on the clay surface. This coating acts as a chemical shield, which prevents subsequent wellbore fluids from interacting with the formation surface.A new chemical treatment has been evaluated and, as discussed in this paper, the laboratory test results indicate the application of a hydrophobic coating offers substantial clay protection in water sensitive environments.
