The Foremost Explorer Series are hydraulic top drive rigs designed for shallow oil and gas drilling to depths of 6,000 ft (1,800 m). A unique hydraulic pullback and pulldown system delivers hoisting capacities up to 130,000 lbs (58,967 kg) with no mast crown load. The Explorer Series is capable of both vertical and slant drilling.

The Foremost Explorer Series are hydraulic top drive rigs designed for shallow oil and gas drilling with the ability to handle Range III tubulars. The unique hoisting system utilizes hydraulic cylinders rather than the conventional draw works. This hoisting system allows the operator the ability to either pull back or pull down at anytime and is ideally suited for applications such as top-hole drilling, setting of surface casing or directional drilling.

The Foremost Explorer Series of drilling rigs were first introduced in the early 90s and since then has evolved to be one of the most versatile rigs in the industry today. Based around a modular design, the Explorer Series offers a large selection of options, which allows every rig to be customized to suit the individual requirements of each customer or application.

FUNCTION & OPERATION

The floating cushion sub performs two important functions. It provides a means of making up and breaking out threaded connections on casing and drill pipe, and also prolongs bearing and gear life in the top drive rotary box. By incorporating a certain amount of axial movement below the top drive gull, the sliding spindle of the cushion sub will allow the threads of the mating drill string components to float together or apart during rotation without any axial movement of the rotary head.

PERFORMANCE

Models 359150 and 375300 are utilized in vertical and angle drilling operations where the rig is equipped with a top drive rotary gear box. The allowable movement of the sliding spindle within the cushion sub housing decreases the impact on the rotary drive spindle when the mating threads are stabbed together. It will also decrease the load on the flanks of the threads and mating components.
