The firearm fore grip for use with a firearm having a barrel extending along a bore axis and an attachment rail operatively associated with the barrel and extending along the bore axis. The firearm fore grip comprises a base configured to engage an attachment rail, the base having a leading and a trailing end. A first hand contact surface is configured to extend substantially parallel to the attachment rail from the leading end of the base. A second hand contact surface extends from the first hand contact surface intermediate a leading and trailing ends of the base at an obtuse angle relative to the first hand contact surface.

A flash system and method is disclosed to control the rate of flashing a reservoir fluid sample from reservoir conditions to a given pressure and temperature in order to produce a liquid and a gas phase of the sample. The flash system comprises a flash apparatus including a separating chamber, a metering valve positioned at an inlet of the separating chamber, and a gas flow meter positioned at an outlet of the separating chamber. A pump is provided to displace the sample from a sample chamber to the flash apparatus, wherein the pump speed and the discharge rate of the metering valve can be automatically controlled. The flash system may be used in a laboratory environment and at the site of an oilfield reservoir. The present disclosure provides a universal flash system and method that can limit operator actions to a minimum of simple operations to ensure the repeatability of the process independent of the operator's skill.

An apparatus for generating a seismic signal in a wellbore includes an elongated housing configured to be disposed in the wellbore; a piston slidably disposed in an internal bore in the elongated housing; a strike plate fixed on the elongated housing proximate one end of the internal bore; and an energizing mechanism configured to move the piston to hit the strike plate. A downhole system for seismic survey of a formation penetrated by a wellbore includes at least one seismic receiver; a seismic source; and at least one inflatable packer configured to separate the seismic source and the at least one seismic receiver in different compartments in the wellbore when inflated.
