| titleOfInvention | Drilling fluid for use in horizontal directional drilling operations |
| abstract | Methods of circulating a drilling fluid while drilling a shallow wellbore that is highly deviated or horizontal. The drilling fluid comprises an aqueous base fluid, iota carrageenan, partially hydrolyzed polyacrylamide, and a divalent cation selected from the group consisting of a calcium ion, a magnesium ion, and any combination thereof. The shallow wellbore that is highly deviated or horizontal is no greater than about 610 meters below an earth surface, and in a range of about 55 to about 125 from a vertical inclination. |
