Developing large acreage positions of unconventional and conventional oil and gas resources
Just reviewing a few things from the past and came across this from last year
"ExxonMobil announced plans to begin commercial evaluation of unconventional hydrocarbon potential covering 184 thousand acres and exploration activities on an additional 387 thousand acres in the Mako Trough in southeast Hungary."
The 184,000 acres is the Falcon / Exxon / Mol area. The additional 387,000 acres is the Exxon / Mol area. They clearly made a distinction of the scope of work in these areas.
Going by this statement, I'm assuming that the 2 wells in the Exxon/Mol area are exploration wells, and the F-1 well, which should be spudded soon, is an appraisal well.
They will all most likely be tested in the spring, however the types of tests might differ. Being exploration wells, the objective is not to determine flow rates, but simply to determine if the gas actually exists at those locations.
The difference between these types of wells is clearly explained in the Falcon / Exxon operating agreement. I can't find anywhere where the Foldeak-1 is referred to as an 'appraisal well', however, since it is within 1 km of the Mako-6, I can't imagine the need for another exploration well in that location.
Appraisal Well means any well (other than an Exploration Well or a Development Well) whose purpose at the time of commencement of drilling such well is to appraise the extent or the volume of Hydrocarbon reserves contained in an existing Discovery.
Exploration Well means any well the purpose of which at the time of the commencement of drilling is to explore for an accumulation of Hydrocarbons, which accumulation was at that time unproven by drilling.
