(a) After completion of and after cleanup or stimulation, but before placing the well on production, the operator of a “Bass Island” well must measure initial bottom hole pressure. The operator must do this by shutting-in the well for a minimum of 72 hours and then obtaining a bottom hole pressure, using best efforts to obtain that pressure by running a pressure bomb as close to the midpoint of the production zone as prudent practices indicate, making gradient stops 1,000 feet and 500 feet above that point of sufficient duration to record the pressures at each of those levels. In instances where wellbore conditions and/or equipment would make the use of a pressure bomb imprudent, the operator must determine a bottom hole pressure by calculations based upon a dead-weighted surface pressure and measurement of any liquid level in the wellbore.
