History and Background

Stable Services was formed in 1978 and has remained independent with self financed expansion.

Nature of Business

The company has always specialised in the repair and manufacture of drilling tools. Stable Services have decided to change the nature of their company from basic repair and manufacture into an engineering based organisation capable of designing, manufacturing and supporting innovative drilling tools. As a result of this organisational change the company has recently moved it's design team to the Technology Park in the Bridge of Don, Aberdeen.

Expansion of the Business

The company have identified a solution to the process of "Hole Cleaning" or cutting removal during the drilling process, by devising two new tools; Low Torque Drillpipe (LTDP) and a pressure operated Jetting Sub.

New Products

Low Torque Drillpipe (LTDP)

This new drillpipe design has already established itself in the North Sea.

The Low Torque Drillpipe has a configuaration similar to that of standard drillpipe, with the addition of three integral bladed centralizers placed on the drillpipe body at approximately 8 feet from the tooljoints and one in the centre, each centralizer consists of three spiral blades which are coated with a special alloy to provide low coefficient of friction and therefore reduce torque and casing wear. The spiral blades are designed with an aggressive leading edge to disturb cutting beds, thereby improving hole cleaning. The blade section have a greater O.D. than the tool joint to reduce the degree of contact with the side of the hole.

Essentially the LDTP improves hole cleaning, reduces torque and drag, casing wear and differential sticking risks and therefore making the task of drilling extended reach, high step out and horizontal well much easier.

Jetting Sub

This is a new circulating retro Jetting Stabilizer/Sub which has been developed in prototype form, full development is planned in the second half of 1995.
