Case Study: Successful Primary Cementing Saves Chevron USD 12 Million in Gulf of Mexico

Preplanning results in successful primary cementing job, saving 3 days of rig time offshore Louisiana

Challenge: Optimize job parameters to avoid remedial squeeze job and NPT costs related to cementing.

Solution: Perform computer simulations using CemCADE cementing design and evaluation software and WELLCLEAN II engineering solution software to obtain accurate information about centralization, preflush volumes, fluids friction pressure hierarchy, and displacement.

Result: Saved an average of 3 days of rig time for each string and USD 12 million by eliminating the need for remedial jobs to be performed on the casing strings.
