ENHANCED OIL-BASED FOAM DRILLING FLUID COMPOSITIONS AND METHOD FOR MAKING AND USING SAME
摘要
New oil-based foam drilling fluids for oil and/or gas wells are disclose as well as methods of making and using same. The new oil-based drilling fluids including a base oil, a foaming agent and a polymer including at least one aromatic olefin monomer and at least one diene monomer, where the polymer improves foam properties rendering a foam stable at temperatures at or above 300°F and even at temperatures at or above 350°F.
