Try to set a new argument in the `xml` for the `logo` block something like:

    <referenceBlock name="logo">
        <arguments>
            <argument name="logo_img_width" xsi:type="number">147</argument>
            <argument name="logo_img_height" xsi:type="number">103</argument>
            <argument name="logo_file" xsi:type="string">your_logo.img</argument>
        </arguments>
    </referenceBlock>
