Abstract
A powder composition for use in preparing flooding fluid for use in petroleum recovery from a petroleum-bearing formation includes an oxygen scavenger and a polymer material. Methods for preparing flooding fluid and for petroleum recovery from a petroleum-bearing formation employ the powder composition.
Claims20
A composition comprising:
- an oxygen scavenger;
- and
- at least one polymer material that is suitable for the preparation of flooding fluid for use in enhanced oil recovery, wherein the composition is in powder form and wherein said oxygen scavenger is present in an amount at least great enough to provide a flooding fluid having a level of dissolved oxygen that is less than a detectable amount.
A process for preparing a flooding fluid for use in petroleum recovery operations, the process comprising the steps of:
- providing an input fluid;
- providing a powder composition including a polymer material and an oxygen scavenger;
- and
- mixing the powder composition and the input fluid.
