Rheology and Stability of Saudi Cement for Oil Well Cementing

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...

Finite element analysis of the effect of cementing concepts on implant stability and cement fatigue failure

BACKGROUND AND PURPOSE Two contradictory cementing techniques (using an undersized stem versus a canal-filling stem) can both lead to excellent survival rates, a phenomenon known as the "French paradox". Furthermore, previous studies have indicated that the type of bone supporting the cement mantle may affect implant survival. To further evaluate the mechanical consequences of variations in cem...

Experimental Investigation of Silica Fume as a Cement Extender for Liner Cementing in Iranian Oil/Gas Wells

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

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...
