  • a sidecar of the present disclosure may save considerable time, because particular equipment may no longer need to be disconnected and individually transported to each wellbore.
  • a sidecar of the present disclosure may be designed such that, when in a side configuration, a majority or substantial portion of the load is centered over or near the outboard wheel sets. Additionally or alternatively, the sidecar may have one or more wheels or wheel sets nearer to a center of the sidecar or a centerpoint of the load of the sidecar. In either case, when in the side configuration and connected to a drilling rig, the load placed on the drilling rig from the sidecar may be reduced or minimized so as to reduce or minimize impact to the existing suspension capacity of the drilling rig.
  • a drilling rig sidecar for holding and/or transporting particular drilling equipment has been disclosed.
  • a sidecar of the present disclosure may have various configurations, such as a side configuration, a skid configuration, and a trailer configuration.
  • the side configuration may be suitable for transporting drilling equipment alongside a drilling rig for particular moves such as between adjacent wellbores at a pad drilling site.
  • the skid configuration may be suitable for drilling operations.
  • the trailer configuration may be suitable for transporting drilling equipment for particular moves such as to or from a pad drilling location.
  • a sidecar of the present disclosure may be used with existing drilling rigs without imparting substantial additional loading onto the drilling rig.
  • the terms “substantially” or “generally” refer to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result.
  • an object that is “substantially” or “generally” enclosed would mean that the object is either completely enclosed or nearly completely enclosed.
  • the exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have generally the same overall result as if absolute and total completion were obtained.
  • the use of “substantially” or “generally” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result.
  • an element, combination, embodiment, or composition that is "substantially free of or "generally free of an ingredient or element may still actually contain such item as long as there is generally no measurable effect thereof.

Abstract

La présente invention, dans certains modes de réalisation, concerne une nacelle latérale d'appareil de forage permettant de transporter de l'équipement de forage. La nacelle latérale peut comporter de l'équipement tel qu'un dégazeur, des tamis vibrants, des réservoirs de récupération, des pompes de mise sous pression, des châssis de manifold de duse, ou d'autres équipements de circuit à boue et/ou d'autres équipements de forage. La nacelle latérale peut être reliée à un appareil de forage et peut être située de façon que l'équipement sur la nacelle latérale puisse être raccordé directement à l'appareil de forage lorsque de tels raccordements sont appropriés. La nacelle latérale peut être configurée pour se déplacer sur des roues, qui peuvent être mobiles, de façon que la nacelle latérale puisse être configurée dans une configuration latérale pour des déplacements de courte distance à côté d'un appareil de forage, ou une configuration de remorque pour des déplacements de longue distance, par exemple sur une route.
