.... The last 8 1/2-in. interval is drilled through the main pay zones in the Kareem, Rudeis, Cenomanian and Nubia formations followed by the 7-in. liner casing and cementing operations. The cement program was designed as a lead and tail slurry with properties to achieve optimum cement placement...

... on compressive strength development. The optimization of slurry design takes all of these parameters into consideration while resolving the problem of heat insulation, thus helping reduce the chance of primary cementing failure over the life cycle of the well. The optimization of the cement slurry design makes...

... increase the temperature of the surrounding formation. These factors could destabilize the hydrates. Cement slurries are designed to lower the heat of hydration while meeting or exceeding the other properties needed for successful deepwater cementing. Heat of hydration is reduced by a factor of more than...

... and surprising, being in many respects counter to accepted oilfield intuition. The direct application of these results is in the design of spacer and cement slurry properties for effective mud removal during primary cementing. The breakdown of zonal isolation can sometimes be attributed to poor bonding...

... in Indonesia are now benefiting from this new technology. Slurries are mixed and tested to ensure they meet design specifications well before they are required on site. The "Base Slurry" or "Liquid Cement Premix", which typically has a density of 16.0 pounds per gallon (ppg), is transported to the rig, diluted...

... normal drilling operations provides essential information needed when designing cement slurries for critical primary cement jobs. The temperature memory recorder can be tripped into the well with pipe or wireline and can be dropped down the drillstring or tubing. Retrieving can be accomplished...

... has shown remarkable success. LCL cement additive is a liquid additive designed to lower equivalent circulating density (ECD) and impart excellent fluid-loss control, high-temperature suspension properties, and acid resistance to cement slurries. This paper summarizes the operational and logistical...

... and regulations of environmental requirement, but also contributes to environmental protection. The deepwater cement slurry, designed by using the DWC cement, environmentally friendly additives and micropheres, presents high early strength under low temperature, right-angle-set, short transition time of static...

... ABSTRACT Gas hydrate dissociation would damage the cementing quality seriously due to the hydration exothermic of cement slurry. Therefore, the well cement slurry with low hydration exothermic is necessary. The design of well cement slurry with low hydration heat mainly includes three steps...

... identified that TOC has not covered the depleted sand ( Gorman 2021 ). The cement job has been pumped as per the designed parameters, adding conventional fibers into the cement slurry and minimizing the displacement rates as simulated by cement job modeling software to decrease the risk of losses. However...
