Walnut shell is used as nutplug, %100  biodegradable that’s why walnut shell media is accepted for environmental protection.

Walnut shell is used as lost circulation material to combat typical operational problems associated with drilling mud losses.  Walnut shell is an easy and efficient solution to lost circulation problems.  Walnut shell does not significantly change mud properties and can be removed and perhaps recycled with ease.  Walnut shell is available in coarse, medium and fin grit sizes.

Lost Circulation Material

Walnut shell is ground walnut shell, a lost circulation material that can be used in both oil-base and water-base systems.  Walnut shell can be mixed in combination with other LCM.

As a lost circulation material walnut shells are especially adapted for plugging induced fractures. Walnut shells are also used to reduce torgue and drag of drill pipe and drill collars, especially in high angle holes. Walnut shells are used as a sweep to scour the well bore and tools when sticking clay is a problem.

Here are the advantages of using nutplug

1- Seal fractures and permeable zones to prevent loss of fluid

2- High compressive strength/non-absorbing

3- For information concerning environmental regulations applicable to Walnut shell,contact the Health Safety and Environmental Department.

Bioshell walnut shells, because of their high compressive strength, are the most resistant to breakdown and degradation of all lost circulation materials. As a lost circulation material Bioshell walnut shells are especially adapted for plugging induced fractures. Bioshell walnut shells are also used to reduce torgue and drag of drill pipe and drill collars, especially in high angle holes.

Bioshell walnut shells are used as a sweep to scour the well bore and tools when sticking clay is a problem. Bit balling is often treated with this product. WALNUT shells provide a lost circulation material for plugging of fractures and high porosity formations. It is an important part of an LCM package. More than 75% of the particles fall within the following size ranges for the three different grinds available: ? Fine 300 – 600 microns ? Medium 600 – 850 microns ? Coarse 850 – 1400 microns In directional and horizontal drilling

Bioshell walnut shells can provide a means of reducing torque and drag. As a sweep, Bioshell walnut shells help clean the bit, tools, and well bore of sticky clays. Bioshell walnut shells should be added to any mud type, in amounts indicated by the type of loss. 2-10 ppb is a recommended treatment level. A slug of 5 to 10 sacks is used for reducing torque and drag. Larger sweeps may be required to effectively scour the tools and bit. A slug of 5 to 10 sacks can also be effective in reducing drag while tripping pipe and running casing.

Bioshell walnut shells provide a lost circulation material that is hard and somewhat spherical to provide throat plugging of fractures and high porosity formations. Used in conjunction with finer and more flexible fiber and plate type materials, it is an important part of a lost circulation material package. In directional and horizontal drilling, Bioshell walnut shells can provide a ball bearing effect because of their size, shape and hardness, reducing torque and drag. As a sweep, Bioshell walnut shells have a similar action to coarse sand, scouring the bit, tools, and well bore of sticky clays.

Utilize normal precautions for employee protection when handling chemical products. Use of appropriate equipment is recommended for employee comfort and protection.

Bioshell walnut shell is  loss circulation material  when introduced into the mud, reduces and eventually prevents the flow of drilling fluid into a weak, fractured or vugular formation. These materials are generally fibrous or plate-like in nature. In addition, popular lost circulation materials are low-cost waste products from the food processing or chemical manufacturing industries.

Description:
Bioshell walnut shells manufactured by BIOSHELL LLC is a hard, non chemical , non toxic & biodegradable material .It makes up a large percentage of the nut has a wide range of applications.

Bioshell walnut shells manufactured by BIOSHELL LLC is a hard fibrous product made from crushed walnut shell in accordance with international trade standards .Selected nut shell are ground to granular form in specific size ranges.

Application: Bioshell walnut shells manufactured by BIOSHELL LLC is utilized to control lost circulation in water oil base drilling fluids. It may be utilized by itself in re-circulated fluids or in pill form with fibrous flake material.

Advantages:

  • Bioshell walnut shells manufactured by BIOSHELL LLC is an effective means of Controlling Lost Circulation. The fine grade of walnut shell can be circulated through a 20 Mesh Shale Shaker Screen. Coarse grade will be removed from the system unless the solid control / removal equipment is by passed.
  • Bioshell walnut shells manufactured by BIOSHELL LLC is compatible with both water and Oil based Drilling Fluids and is non toxic and biodegradable

Lost circulation is the partial or complete loss of drilling fluid and/or cement slurry to the formation during drilling or cementing operations or both. This can be brought on by natural or induced causes. Natural causes include situations such as naturally fractured formations or unconsolidated zones. Induced losses occur when the hydrostatic fluid column pressure exceeds the fracture gradient of the formation and the formation pores break down enough to receive rather than resist the fluid. When lost circulation occurs, it can provoke new requirements of time and mud or cement – and add substantially to the overall cost of a well.

Drilling fluid and Bioshell walnut shell Lost Circulation Material play a vital role in the success of any operation. Fluids are responsible for the continuous removal of drill cuttings, but excessive use can lead to more serious problems such as bridging, bore blockages, stuck pipe, loss of circulation and reduced drill penetration rates.

Although drilling fluids come in many forms such as clear water or formulations of clays, thickeners and weighing agents, however sophisticated and/or expensive a drilling fluid is nothing can be more expensive than lost time. To prevent problems like this it is necessary to use Bioshell walnut shell in conjunction with a drilling fluid.

Bioshell walnut shell is used in conjunction with drilling fluids and is added to mud formulations as a granular type lubricant to reduce the drag and torque of drill pipe and collars.  Bioshell walnut shell is also used as an effective lost circulation material and is proven to prevent seepage loss.

Whilst Bioshell walnut shell as is an effective lubricant and Lost Circulation Material it is also used as a sweep to clean the drill head, tools and bore of sticky clays.

Bioshell walnut shell is an important part of any loss prevention or lost circulation package.

Bioshell walnut shell Lost Circulation Material is manufactured in a range of sizes, including custom, to suit your drilling applications and requirements.  Bioshell walnut shell is either manufactured to order (custom) or delivered from a range held in stock ready for immediate dispatch to your destination of choice.

Lost Circulation leads to formation instability, whole mud losses and significant expense

The seepage of drilling fluid to the formation while drilling is a perineal problem with a variety of causes, both naturally occurring and drilling-induced, that all result in well instability and the loss of significant volumes of drilling fluid. The result is unexpected cost for the driller and potential well instability.
