  • Adjustable injection valve for a plug and abandonment anchoring device
    Patent number: 11920430
    Abstract: A wellbore anchoring device having an adjustable injection valve is disclosed. The anchoring device can include the adjustable injection valve and a spring. The spring can be positioned adjacent to the adjustable injection valve. The spring can include an initial pressure setting that is adjustable prior to the anchoring device being positioned in a wellbore to adjust a cracking pressure of the adjustable injection valve.

  • Verifying measurements of elastic anisotropy parameters in an anisotropic wellbore environment
    Patent number: 11237288
    Abstract: A portion of an anisotropy formation through which a wellbore is formed can be identified. An estimate of an elastic anisotropy parameter for the portion can be adjusted based on a first quality control analysis using the elastic anisotropy parameter for the portion. The first signal representing the elastic anisotropy parameter for the portion. The estimate of the elastic anisotropy parameter for the portion can be adjusted based on a second quality control analysis using estimates for the elastic anisotropy parameters for two or more portions of the anisotropy formation.
