Problems solved by technology

An inherent problem with formation detectors used in cased wells is that most of these tools need to be supplemented or plugged with casing perforations in order to allow direct measurement of formation fluid pressure

Embodiment Construction

[0034] figure 1 Shown is a drill collar propelling gun 10 within a drill collar 12 within a drill pipe extending into a drilled wellbore. The drill collar propelling gun 10 has a hole 22 through which the bullet-shaped data detection device is fired from the drill collar propelling gun 10 . As shown, a deployed data detection device 24 has been deployed from the drill collar thruster 10 into the formation matrix 20 in the formation of interest.

[0035] figure 2 Shown is a cross-sectional view of the collar pusher gun 10 of the present invention. As shown, the barrel 32 is generally oriented in a cross-sectional plane of the wellbore, which is generally perpendicular to the depth axis of the wellbore. Those skilled in the art know that the data detection device is buried radially outward from the axis of the wellbore and laterally, and does not have to be perpendicular to the axis of the wellbore, and can also be inserted into suitable rock formations concerned at various ...

Abstract

An apparatus and method are provided for deploying a data sensing apparatus into a subsurface geologic formation for intermittent or continuously gathering data from the subsurface formation and transmitting the data to a remote data receiver. In a preferred embodiment, a non-linear arrangement of a barrel and a burn chamber is used to provide a gun-like device for firing a bullet-shaped data sensing apparatus into a formation of interest. The data sensing apparatus, once disposed within the matrix of the formation of interest, monitors formation conditions and transmits the data for use in optimizing drilling and production activities.

Description

field of invention [0001] The present invention relates broadly to the monitoring of a subterranean geological formation of interest and, more particularly, to a launch arrangement for ejecting a data monitoring device into a subterranean geological formation of interest to enable monitoring. Background of the invention [0002] Drilling wells can exploit natural deposits of hydrocarbons and other materials in subterranean geological formations in the Earth's crust. Elongated wells are drilled into the ground and directed from a drilling rig at the surface or at the surface of water (eg, ocean) to a subsurface target location. In a common "rotary drilling" operation, a drilling rig rotates a string of drill pipe consisting of steel pipe joints joined together to form the drill string. The drill string is used to rotate a bottom hole assembly (BHA) and a drill bit connected to the bottom end of the drill string. During drilling operations, drilling fluid, commonly referred ...
