Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to automatically improving performance of coiled tubing operations in substantially real time by inferring reservoir pressure based on initial coiled tubing run conditions. For example, a method includes performing a coiled tubing operation via a coiled tubing system at least partially disposed within a wellbore. The method also includes detecting data relating to operating parameters of the coiled tubing operation via sensors of the coiled tubing system during the coiled tubing operation. The method further includes determining an initial wellbore fluid distribution in the wellbore based on the detected data prior to pumping fluid into the wellbore from a surface location relative to the wellbore. In addition, the method includes inferring a reservoir pressure of a hydrocarbon-bearing reservoir through which the wellbore extends based on the initial wellbore fluid distribution in the wellbore.

Abstract: A diffractive optical element, such as a holographic plasma lens, can be made by direction two laser beams so that they overlap in a nonlinear material, to form an interference pattern in the nonlinear material. The interference pattern can modify the index of refraction in the nonlinear material to produce the diffractive optical element. The interference pattern can modify the distribution of plasma for the nonlinear material, which can adjust the index of refraction. A third laser beam can be directed through the diffractive optical element to modify the third laser beam, such as to focus, defocus, or collimate the third laser beam.
