Abstract
Methods and compositions for gravel packing a wellbore penetrating a subterranean formation are described. The methods include providing a gravel packing fluid and contacting the subterranean formation with the gravel packing fluid so as to place a gravel pack in or near a portion of the subterranean formation. The gravel packing fluid includes a particulate agent and hydroxypropyl starch phosphate.
Claims20
A method of gravel packing a wellbore penetrating a subterranean formation comprising:
- providing a gravel packing fluid comprising a particulate agent and hydroxypropyl starch phosphate, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.1 to 10 weight percent of the gravel packing fluid;
- and
- contacting the subterranean formation with the gravel packing fluid so as to place a gravel pack in or near a portion of the subterranean formation.
A method of gravel packing a deviated wellbore penetrating a subterranean formation comprising:
- providing a gravel packing fluid that comprises hydroxypropyl starch phosphate, a particulate agent, and an aqueous carrier fluid, wherein the hydroxypropyl starch phosphate is present in the gravel packing fluid in an amount of about 0.1 to 10 weight percent of the gravel packing fluid;
- introducing the gravel packing fluid into the subterranean formation through the deviated wellbore;
- and
- depositing the particulate agent within the deviated wellbore to form a permeable pack.
