Composite proppant particles each of which comprises a plurality of microbubbles and a resin binder are disclosed. Also disclosed are a method of using such composite proppant particles to prop fractures in wells formed in underground formations.
摘要:
Raw product comprising glass microbubbles is formed by heating feed having a size distribution with a span of less than 0.9. The raw product may have a size distribution with a span of less than 0.80.
摘要:
A syntactic foam and water-based explosive comprising glass microbubbles formed by heating feed having a size distribution with a span of less than 0.9 that are dispersed in a polymeric matrix or emulsion explosive. A method for making glass microbubbles, syntactic foam and water-based explosives is described.
摘要:
The present invention provides a drilling fluid composition and a method of drilling comprising a drilling fluid, which may be oil- or water-based, and a composite microsphere component. The invention drilling fluid composition advantageously reduces the density of a conventional fluid, reduces costs associated with pumping and overcomes problems associated with conventional gas-injection processes. The invention uses conventional drilling and pumping equipment, requires no sea-floor based pumps and may be easily pressure-controlled to maintain the pressure of the fluid.
