The current situation doesn’t make a lot of sense to me. The management teams at these companies don’t give investors enough information to value the assets. I think that investors would demand such information. They should know the historical and projected decline curves of their company’s assets (for each basin the wells are in). This is very basic information that investors need to perform their due diligence.
Another way of looking at it is to examine how a private market buyer would perform due diligence. When an oil and gas company wants to sell its assets to private market buyers, it typically opens a data room. I’m sure they provide a large volume of technical data far beyond decline curve data (e.g. reservoir models, data on porosity, pressure, 3-D seismic, etc. etc.). Institutional investors and analysts simply don’t perform that level of due diligence.
