JMF was requested to design and bore a 24″ Steel Pipeline crossing of a local state route. The topography surrounding the state route required relatively shallow depth when approaching the roadway. The shallow depth paired with the general instability of the subsurface conditions required JMF to be extremely careful when boring as there was always an immediate chance of frac out. Despite the concerns, through carefuly monitoring of drill fluid returns and drilling pressures, along with multiple hole swabs during pilot and reaming, JMF did not have a single loss of returns or frac out.
