For years, the reduction of tubular inside diameter (ID), or “telescoping effect,” limited the exploration and production of oil and gas. Using conventional technology, operators faced significant loss of ID in the course of the normal drilling process, during reentry and deepening of existing...

A major operator in the Norwegian North Sea anticipated problems while drilling a    12-¼ x 13-½ in. hole section which required setting 10-¾ in. casing early. This left a section of overburden exposed above the reservoir. 

The 8-5/8 in. ESET HP System isolated the overburden section,...

An Operator drilling multiple wells in South Texas encountered a loss zone 500 ft. below the shoe of the intermediate casing in their well. The Operator had also encountered this loss zone on two offset wells and was prepared with options to address the loss zone. Normally 9-5/8 in. casing is...

An Operator in the Norwegian North Sea encountered a restriction 118m (387 ft.) off bottom while running a 10-¾” MLT liner. This was the third attempt to pass the trouble spot. The decision was made to cement the MLT liner in place and find an alternative way to cover up the troublesome Balder...
