GN Shale Shaker

Please find information on Derrick 600 DP Shaker, Mongoose dual motion shale shaker, GNPS Shale shaker. You can find how do shale shakers work, different shakers hold different performance in variouse motion.

Derrick DP600 shaker

The revolutionary DP 600 shaker provides increased capacity without enlarging its footprint. Fluid Centering Technology maximizes fluid throughput by forcing the feed to the center of each of the two concave screen beds.

More API screen area increases capacity, potentially reducing the number of shakers required.  The screen support structure’s stainless steel construction results in maximum durability prolonging life. Easy to install, oil-resistant bed cushions provide an all-important complete seal with no hardware required.

Scalping deck

 
The optional scalping deck provides coarse solids removal, reducing the feed load on the primary deck, resulting in an increased life of primary deck screen panels.

The scalping deck’s unique design increases available API screening area and can be utilized for reclamation of Loss Circulation Material (LCM). Unobstructed access is provided to the primary deck for inspection, cleaning and rapid screen replacement. The scalping deck may be bypassed allowing process material to flow directly to the primary deck.

Derrick‘s long-life urethane screen panels (patent pending) are inherently non-blinding, abrasion-resistant, oil-resistant, and permit fast, easy removal and installation.

Mongoose Dual Motion shaker

Dual‐motion MONGOOSE shakers applied in Lake Maracaibo proved to be a successful solution to the previous experiences of operators in the region. Operators had found wells in this region challenging as a result of the need for high drilling rates and incidence of a high percentage of drill cuttings. These cuttings were saturated with oil‐base mud.

The conventional possum belly designs that had been used in the region are known to progressively accumulate drill cuttings, eventually leading to flowline plugging. Elimination of the possum belly in the MONGOOSE design significantly reduced obstructions on the flowline while drilling both Lake Maracaibo wells.

GNPS Ballanced Elliptical Shaker

GNPS series balanced elliptical shale shaker  is the fourth generation Patented shale shaker introduced by GN and Southwest Petroleum University. It is the advanced shale shaker known in the world. It holds much more treating capacity cater to drilling mud system high capacity

In 2009,this Shaker research project got approval from National Technology Commission and gets the “National Technology Progress” Award. GNPS balanced elliptical shale shaker designed from uneven diameter principle, and applied patent successfully; compared with overseas famous companies’ even diameter principle, both theoretically and practically, GN patented shaker is better.

Oil well Shale Shaker brief introduction

The shale shaker is as its name description of what does it do. The basic design consists of large,  flat sheets of wire mesh screens or sieves of various mesh sizes that shakes or vibrates the drill cuttings, commonly shale, across and off of the screens as the drilling fluid flows through them and back into the drilling fluid system, often called a mud system.

Shale shakers are devices that remove drill cuttings from the drilling fluids while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since solids control is vital in keeping down costs associated with the drilling fluid.
