Methods for cementing in a subterranean formation using a cement composition containing a set retarder of a polyester

A method of cementing in a subterranean formation comprising:

• introducing a cement composition into the subterranean formation, wherein the cement composition comprises:
• cement;
• water;
• and
• a polymer, wherein the polymer:
• (i) is capable of providing a thickening time of at least 2 hours at a temperature of 400° F. (204.4° C.) and a pressure of greater than about 500 psi (3.4 MPa) for a test composition consisting essentially of:
• the cement;
• the water;
• and the polymer, and in the same proportions as in the cement composition;
• (ii) increases the setting time of the cement composition due to degradation of the polymer;
• and
• (iii) is polylactic acid or polyglycolic acid,
• wherein the subterranean formation has a bottomhole temperature greater than or equal to the glass transition temperature and/or the melting point temperature of the polymer;
• and
• allowing the cement composition to set, wherein the polymer does not create voids in the set cement composition.
