| 发明名称 | Fluid pressure transmission pill | ||
| 摘要 | A pill for wellbore operations, that includes a base fluid; and at least two polymers that interact to form a gelatinous structure characterized as isolating and controllably transmitting hydrostatic pressure between a first wellbore fluid above the pill in a wellbore and a second wellbore fluid below the pill in the wellbore is disclosed. | ||

| 主权项 | 1. A method of a wellbore operation, comprising: emplacing a first wellbore fluid in a wellbore; spotting a pill to a region within the emplaced first wellbore fluid; and allowing the spotted pill to viscosify and separate the first wellbore fluid into an upper section and a lower section, wherein the viscosified pill is a gelatinous structure characterized as isolating and controllably transmitting hydrostatic pressure between the two fluid sections. | ||
