“…DNWR is a polymer that is cross-linked with a resin system that contains two independently cross-linked networks . One is a rigid polyelectrolyte that can tolerate high tensile stress, and the other is a flexible neutral polymer that is devised to relax stress . This structure can supply strong strength and avoid the generation of fractures.…”

Carbon capture and storage (CCS) technology has been widely investigated to decrease the greenhouse effect. Geological CO2 storage sites are targeted mainly on depleted petroleum reservoirs or deep saline aquifers. However, CO2 leakage might take place through wellbores, cap rocks, reservoir fractures, or faults during or after the process of CO2 storage leading to environmental problems. To minimize these hazards, different kinds of sealants have been developed and applied. This review aims to summarize those materials applicable to CO2 leakage remediation. On the basis of the sealing mechanisms and compositions of different sealant materials, they were divided into seven major types: Portland cement, geopolymer cement, resins, biofilms barriers, gel systems, foams, and nanoparticles. For different types of sealants, their application background, chemical and physical properties, CO2 leakage remediation mechanism, impact factors of sealing performance, advantages, and limitations were summarized. Future development directions for these sealant materials are also recommended. To solve the problem caused by the weak acid-resistant performance of Portland cement, anti-CO2 materials should be developed and added to the formulation. Environmentally friendly materials need to be designed to replace some current user-hostile compositions in the geopolymer cement. Moreover, chemicals that can control the geopolymerization process are also required because of the high curing temperature requirement for the recent geopolymer productions. The injectivity of Portland cement and resin limits its application for in-depth CO2 leakage control; however, gels with relatively low viscosity during the injection can be a good alternative, although their thermal stability and strength need to be further enhanced. Biotechnology and nanotechnology are perspectives to be applied in the CO2 leakage control process. Foams with good stability might be used for CO2 leakage remediation in the porous medium without fractures, but their life cycle should be prolonged.

The problem of lost circulation occurs almost permanently during drilling operations. When drilling highly permeable, highly fractured, and depleted zones, large drilling fluid losses lead to increased operational expenses. Lost circulation may have several consequences, including fluid inflow, wellbore collapse, formation damage, nonproductive rig time, and environmental issues. In the last century, lost circulation has presented great challenges to the petroleum industry, requiring large capital expenditures and time to address the problem. A particular challenge is depleted reservoirs. As the reserves decline, pore pressure decreases, resulting in weakened hydrocarbon-bearing rocks; nearby or inter-bedded low permeability rocks, however, may maintain their pore pressure. This situation can make the drilling of certain depleted zones extremely difficult. Generally, the fluid density necessary to support the shale above exceeds the fracture resistance of the sands, silts, or carbonates below. Consequently, it is vital to design the drilling fluid to minimize mud invasion into formation and prevent lost circulation, and to provide the possibility of removal at a later stage (completion).To mitigate circulation loss risks, a broad range of treatments and preventive methods using lost circulation material (LCM) have been tried and recommended over the years with varying degrees of success and efficiency. This paper presents an extensive review of the applications of various technologies, both proven and potential, in LCM for sandstone and carbonate depleted reservoirs. It describes the state of the art, advantages, limitations, and suggested specific applications. It also presents recent references of their uses in the petroleum industry and discusses the application and the status of the technologies.For sandstone, the materials discussed focus on LCM in the form of flakes, granules, fibers, blends of these materials, particulate materials, polyglycolic acid (PGA) and polylactic acid (PLA) materials, as well as nanoparticles (NP) and nanocomposites. For carbonate formations, the scope includes conventional LCM, such as cement plugs, settable plugs, polyurethane grouting and other new technologies, such as gels, viscoelastic surfactant gels (VES), and crosslinked gels.This review compiles crucial information necessary to design and formulate the fluid using LCM for the depleted reservoir challenges.

“…Double absorbent water-soluble resins have been described as loss circulation materials that can be used at temperatures up to 150 °C for more than 30 days. The resin after being pumped into the formation fracture has been designed to expand 5-10 times its original volume, adsorb on the fracture surface, and form a compact sealing layer [13]. Engineered fiber-based loss circulation control pills, based on a specially engineered fiber system and particle size distribution (PSD) principle, were developed to control loss circulation.…”

The loss circulation composition comprising a combination of a nanoparticle-based dispersion and a chemical activator has been designed to treat moderate to severe losses. The nanomaterial used is an environmentally friendly nanosilica-based dispersion. The composition is designed to give delayed gelling of the nanoparticle-based dispersion. A major advantage of this technology is its ability to place the composition into the target loss circulation zone before the nanoparticle-based dispersion gels up. Premature gelling of the nanoparticle-based dispersion would avoid premature setting of the treatment fluid before it reaches the target zone. The newly developed system can be used effectively up to 300 °F. In this paper, experiments have been performed with three different types of nanoparticles differing in their surface charges and particle sizes. Two negatively charged nanoparticle-based dispersions with a particle size of 5 nm and 17 nm, respectively, and one positively charged nanoparticle-based dispersion with a particle size greater than 17 nm have been evaluated as loss circulation materials. Two different types of chemical activators, one organic and the other inorganic, have been used in this study, and their effect on the gelling time has been evaluated. The gelling time experiments have been done at four different temperatures viz. 150 °F, 200 °F, 250 °F, and 300 °F. The effect of activator concentration and different shear rates on the gelling time of the three nanoparticle-based dispersions has been studied. Permeability plugging tests have been performed using 2 mm slotted disks to evaluate the effectiveness in controlling moderate to severe losses.
