I haven't heard much recently on Kings County activity. Some exploratory wells have been drilled and while the oil companies keep the results confidential there have been mixed results from what I hear.
As a mineral owner you will be informed when the oil company intends to go onto the property to conduct certain work, as this is a requirement pursuant to statute, but other than that you won't know how things are going unless and until they have drilled a well that is producing and therefore they begin paying royalties.
The price of oil has impacted some exploration since these wells can cost millions of dollars without certainty that they will produce sufficient oil to make it worth while, but the information that they receive from drilling is helpful as well so they are still moving forward.
The Division of Oil and Gas's website sometimes will show what is occurring on your parcel, but again if the oil company has requested that it remain confidential (and most of the companies drilling exploratory wells do request this) then even the Division's website won't list anything.
Large oil companies have public affairs officers that you can contact to see what is occurring, but they may be limited as to what they can tell you for the reasons stated above.
I know it is frustrating not knowing but in the highly competitive area of exploration, the oil companies invest significant sums and want to attempt to keep the advantage by withholding information on their discoveries until they are required to go public with the information.
