... Abstract A foamed cement solution was designed and implemented to cement shallow intermediate casing strings in a heavy oil play in Northeast Alberta after conventional area-specific cementing solutions could not prevent surface casing vent flows. Analysis of the challenging well parameters...

... Abstract The objective of this paper is to evaluate the physical and dynamic mechanical properties of foamed cement generated at a field site and compare them to similar cements fabricated within the laboratory. Physical and mechanical properties such as porosity, permeability, Young's modulus...

... Abstract Foamed cement is widely used during cementing operations in which lightweight slurries are necessary. Foamed cement helps prevent gas migration and is often used in high-stress environments. A stable foamed cement has a uniform distribution of distinct bubbles, which helps ensure...

... Abstract Foamed cement has provided zonal isolation in oil and gas wells since the 1980s. However, the lack of an experimental technique that fully characterizes foamed cement properties is limiting its application. This study uses X-ray microcomputed tomography (micro-CT) to elucidate...

... 40 wells have been abandoned. This paper will describe best practices learned, as well as "game changing" strategies that have led to significant cost savings and reduced operational risk. These include bullheading foamed cement to abandon the producing zone prior to moving in a service rig...

... Abstract Foamed cement is often used to seal the annulus of many surface casing strings in deepwater offshore wells. The objective of this paper is to highlight the benefits a foamed fluid placement simulator brings to the design and evaluation processes for foam cement jobs. A dynamic...

... and/or foam cement significantly increases the prospect of maintaining circulation throughout cement placement. However, wells with exceedingly low fracture gradients can suffer either partial or complete loss of circulation during cement placement even with lightweight slurries. Both conventional...

... Abstract Data from six deep gas wells in Wyoming indicate that foamed cement outperforms conventional cement for zonal isolation. Two of the six wells were cemented across the production zones with conventional non-nitrified cements. These wells experienced outer-zone communication after...

... have been used in the past to obtain this lightweight slurry. These include the use of natural and chemical extenders, glass bubbles, ceramic bubbles and the combination of intermediate-weight cement slurries with gases. While the process of foaming cement to make lightweight slurries is not new...
