Sustained casing pressure (SCP) is a common problem during an entire life span of oil and gas wells. When conventional methods are deployed to resolve the issue, seem have some setbacks by being unable seal microcracks in wellbores. A new solid-free resin sealant was developed increasing amount active hydrogen curing agent. This low-temperature cure results low viscosity, excellent mechanical properties, chemical stability. The experimental show that can be used at temperatures ranging from...

Sustained casing pressure (SCP) is a crucial issue in the oil and gas production lifecycle. Epoxy resins, exhibiting exceptional compressive strength, ductility, shear bonding have potential to form reliable barriers. The injectivity sealing capacity of epoxy resin parameters for success shallow remediation operations. This study aimed develop assess novel solid-free sealant as an alternative Portland cement mitigating fluid leakage. investigation evaluated viscosity, brittleness index...

ABSTRACT: Underground gas storage is characterized by large injection and withdrawal cycles, making the wellbore bear repeated loading unloading. Subjecting cement sheath to these conditions can cause damage, thus compromising its ability provide complete zonal isolation. Wellbore annulus plugging with high-strength resin technology was studied evaluate effectiveness in controlling unwanted fluid migration through triaxial mechanical properties test, corrosion inhibiting anti-gas channeling...

Supercritical carbon dioxide (SC-CO2) fracturing has been used in developing low permeability and water-sensitive reservoirs recent years, which is expected to become a new generation of unconventional reservoir fluid. However, the water-rock interaction characteristics various lithology shales under SC-CO2 circumstance its influence on effect still need be investigated. Two kinds shale samples from C7 S1 formations Ordos Basin were treated by with formation water. The aims research are...

Deep profile control technology was adopted to mitigate the problem of oil recovery in sandstone reservoirs arising from different permeability. A series core flooding experiments combined with visual and Computed Tomography (CT) analysis were performed study mechanisms control, displacement, rheology, plugging properties modified starch gel polymer gel. Moreover, a comparison made regarding water absorption profile, sweep efficiency, displacement efficiency for both The results show that...
