The prediction of unconfined compressive strength (UCS) of oil well cement class “H” based
on the artificial neural network (ANN) modeling approach is presented in this study. 195 …

In China, most oilfields have entered the late stage of water injection development.
Considering that the injected water quality has not reached the standard for a long time, the …

Drilling ever deeper, and thus in increasingly difficult conditions, is associated with restrictive
requirements that must be met by cement slurries. This implies the need to use advanced …

Activating naturally occurring nanoparticles in the reservoir (clays) to generate Pickering
emulsions results in low-cost heavy oil recovery. In this study, we test the stability of …

O/W emulsion reinforced by nanosilica particle has good application in hydrocarbon
development. However, there are few reports on the influence of nanosilica particles on the …

为了改善常规液硅防气窜剂在超深井中的防气窜性能, 通过在原材料中加入白炭黑和增加砂磨机
物理机械研磨等方式, 对液硅防气窜剂进行了粒径优化并进行了性能对比评价实验 …

Complete zonal isolation along with wellbore integrity is paramount to oil field development
which ensures environmental safety and favorable well economics. However, the complexity …

One of the most common methods used to reduce excessive water production is water
shutoff operations. These types of operations include injection of gel for flow profile …

To improve the gas-channeling prevention performance of regular silica water suspension in
ultra-deep well drilling, the silica suspension was treated with a white carbon black and …

In this paper, the casing strings of cement slurry during the curing period are taken as the
research object in order to build a force model, with comprehensively considering the …
