... of "wastes" contained in the injection water, etc. Because disposal water often contains more amount of "waste", water disposal wells are therefore more prone to formation damage when compared to oil producers only having native reservoir fluids produced. Remedial well treatment is often a mandatory...

... Abstract A major development with multiple rigs delivering extensive multi-laterals encountered a pervasive mud-window issue within the reservoir. The resulting severe mud losses, extensive NPT and formation-damage was also deteriorating with time due to depletion. Conventional approaches...

... Abstract Almost all Malaysian hydrocarbon-bearing sandstone reservoirs contain minerals which are potential sources of mobile fine particles. For this reason, formation damage in injection and production wells has been frequently associated with the migration of fines in reservoir pores...

... Abstract The use of high-density brines has been always considered as afactor in minimizing formation damage during completion operations. However, these brines can be potentially damaging if it is not well designed. Under high temperature conditions, precipitations may occurcausing a rapid...

... Abstract A tight carbonate reservoir is one of the typical formations in the oil and gaswells. The unique feature of the subject reservoir is low permeability (2–5md). The formation damage, compatibility, residual analysis and squeeze lifeare still major challenges for the conventional scale...

... Abstract Mineral scales, in particular calcite (CaCO3) and siderite (FeCO3) have been associated with formation damage in oil fields in Colombia. Scale deposition has been observed within the production flowline as well as in the formation. For many years, this scale problem has been...

The shapes of the above WOEs indicate potential waxdeposition and near-well formation damage in those cases where the Gas condensate contains high carbon number waxes that precipitate in solid state...

... ABSTRACT Subsea completions designed to extract reserves from "conventionally" marginal economic offshore reservoirs require effective prevention and removal of formation damage and present difficult decisions during initial well completion. Subsequent stimulation and workovers may...
