First thank you for your entries. You are prolific in your variety. Although each image definitely captures the "oil" part and "midnight" part through coloring, only
#29 even hints at the "burning" part and none really stand out as separating me from an oil company rather than a technology services company. The name "Midnight Oil Consulting" is not as important to me being in the logo rather than an image or graphic that conveys those words without actually using them. If possible try to incorporate the fact that "I'm a consultant that burns the midnight oil for, to make your technology desires happen" something like that. Thanks.
