Oil Well Cement for high temperature-A review

Inorganic Corrosion-Inhibitive Pigments for High-temperature Alkali- activated Well Casing Foam Cement

A NEW CEMENT ADDITIVE TO IMPROVE THE PHYSICAL PROPERTIES OF OIL WELL CEMENT AND TO ENHANCE ZONAL ISOLATION

The main purpose of cementing of the well is to provide effective zonal isolation for the entire life of wells. The standard cements cannot prevent loss of zonal isolation when the stress level in the well cement is severely fluctuated. Since elastic cements improve elastic properties, recently, a number of studies have been done in this area. For this purpose, a nanoparticle, named EX-RIPI, wa...

An Elastomer Additive Improving Elastic Properties of Heavy Weight Oil Well Cement: A Laboratory Study

The use of elastomer additives to solve the problems in oil well cementing has been investigated in recent years by several research groups in the petroleum industry. This study includes the laboratory examination of the effect of elastomer additives on the physical properties of heavy-weight oil well cement. In the research process, a candidate well is selected and the properties of the cement...

Cellulose Nanofibers as a Modifier for Rheology, Curing and Mechanical Performance of Oil Well Cement

The influence of nanocellulose on oil well cement (OWC) properties is not known in detail, despite recent advances in nanocellulose technology and its related composite materials. The effect of cellulose nanofibers (CNFs) on flow, hydration, morphology, and strength of OWC was investigated using a range of spectroscopic methods coupled with rheological modelling and strength analysis. The Vom-B...

High-temperature tensile properties of a polymer intercalated/exfoliated cement

A polymer intercalated/exfoliated (PIE) cement is synthesized and its high-temperature tensile performance is characterized. Due to the reinforcing effect of the nanointerphase, the flexure strength of the PIE cement is higher than that of ordinary cements by more than an order of magnitude in a broad temperature range. The temperature at which the optimum mechanical properties are obtained is ...
