Paper Number: SPE-198630-MS
... additives improve cement bonding, these results may not be seen due to other cementing job factors. The most common negatively affecting factors are mud removal, poor pipe standoff, hole washouts, or simply insufficient time for crystal growth within the cement matrix. Therefore, expanding additives should...

... ) Sutama and Inayah (2013) used MgO as expanding agent in their successful application in two large gas fields in Sumtra. Their cement recipe was designed to achieve 0.2%-0.3% linear expansion in one week. Thomas et al. (2014) performed laboratory evaluation of expanding cement under confined cell under...

..., unlike liquid, gas flows easily to surface through very narrow microannuli. Cementing operations which fail to provide adequate zonal isolation may result in loss of isolation which poses a hazard to both personnel and the environment. A cement that has ability to expand post set, can help prevent...

Paper presented at the Canadian Unconventional Resources Conference, November 15–17, 2011
Paper Number: SPE-149440-MS
.... To ensure compliance with DEP cementing guidelines, a flexible, expanding cement system (FECS) was developed with fit-for-purpose mechanical properties. A further FECS blend modification included an additive to promote bulk cement expansion during hydration. Since implementation, this approach, coupled...

...P.N. Parker PARKER, P.N., WAHL, W.W., MEMBERS AIME, DOWELL DIV. OF THE DOW CHEMICAL CO., TULSA, OKLA. Abstract Expanding cement is cement to which an expansive component is added. It is a true expanding cement, since the expansion occurs after the cement has set. As expansion occurs, the cement...
