Claims (7)
1. Fremgangsmåde til servicering af en brønd, hvilken fremgangsmåde omfatter: kombinering af et chelateringsmiddel, en syre og et vandigt baseret fluid, der omfatter sulfationer ved en koncentration, der er højere end 50 mg/l, for at danne et surt brøndserviceringsfluid med et pH på 1 eller lavere; og indføring af det sure brøndserviceringsfluid i en brønd for således at stimulere en brøndformation, hvorved en koncentration af multivalente kationer øges i brøndserviceringsfluidet, hvor koncentrationen af chelateringsmiddel ligger i intervallet fra 5 liter pr. 1000 liter til 120 liter pr. 1000 liter; og hvor brøndformationen omfatter mindst én forbindelse valgt fra calciumcarbonat eller calciummagnesiumcarbonat.
2. Fremgangsmåde ifølge 1, hvor koncentrationen af sulfationer er større end 200 mg/l.
3. Fremgangsmåde ifølge 1, hvor mængden af frembragt præcipitat er mindre end 600 g pr. tusind liter (5,0 pptg) og/eller det vandigt baserede fluid omfatter havvand.
4. Fremgangsmåde ifølge 1, hvor syren omfatter HCI.
5. Fremgangsmåde ifølge 1, hvor chelateringsmidlet omfatter mindst én forbindelse valgt fra uorganiske polyphosphater eller polyphosphonsyrer eller salte eller estere deraf.
6. Fremgangsmåde ifølge 1, hvor en kilde af borationer ikke anvendes som et tværbindingsmiddel i brøndserviceringsfluidet.
7. Fremgangsmåde ifølge 1, hvor chelateringsmidlet omfatter mindst én forbindelse valgt fra calciumpolyphosphater, magnesiumpolyphosphater, natriumpolyphosphater, diethylentriaminpenta(methylen phosphonsyre) eller salte eller estere deraf, nitrilotrimethylenphosphonsyre eller salte eller estere deraf, ethylendiaminhydroxydiphosphonsyre eller salte eller estere deraf, ethylendiamintetramethylenphosphonsyre eller salte eller estere deraf eller bis(hexamethylentriaminpenta)methylenphosphonsyre eller salte eller estere deraf.
