How to Determine Depreciation for Water Well Drilling Rigs

 Depreciation of a water well drilling rig can confirm the value of a used transaction, and the following are converted into factors affecting the depreciation of a water well drilling rig

Original cost of the rig:

Includes acquisition cost, transportation costs, installation costs, etc.
Estimated useful life:

Estimate the number of years the rig will be able to provide service based on its type, quality, frequency of use, etc.
Estimated residual value:

Estimated residual value of the rig at the end of its useful life, i.e. the value that can be recovered when it is sold or scrapped.
Depreciation Methods:

Companies can use different depreciation methods such as straight-line method and accelerated depreciation method.

Commonly used depreciation methods

Straight-line method:
The cost of the asset is subtracted from the estimated salvage value and divided by the estimated useful life to obtain the depreciation amount to be charged each year.
Characteristics:

depreciation amount is the same every year, simple calculation.

Accelerated depreciation method:
More depreciation at the beginning of the asset's useful life and less depreciation at the end.
Commonly used accelerated depreciation method:
Double Declining Balance Method: The annual depreciation amount is 2 times the net value at the end of the previous year multiplied by the depreciation rate.
Sum-of-the-years method: annual depreciation is (estimated useful life - number of years used + 1) / (estimated useful life × (estimated useful life + 1)) × (cost - salvage value).
Characteristics:

More in line with the law of diminishing asset value over time.

Cautions

Stability of depreciation policy:
Enterprises should develop a uniform depreciation policy and keep it relatively stable to avoid frequent adjustments.
Selection of depreciation methods:
The selection of depreciation methods should be in line with accounting standards and truly reflect the changes in the value of assets.
Periodic review:
Enterprises should regularly review fixed assets and adjust depreciation methods or depreciation lives according to the actual situation.
Tax impact:
The choice of depreciation method will affect the enterprise's income tax, and the enterprise should consider both financial and tax factors.

How to extend the life of drill pipe

  1. When using a new drill pipe, the drilling rig manufacturer should make sure that the wire fasteners on the front cut-off (protecting the shaft head) of the drill bit are also close to the new one. A ring-buckled rotating head can easily damage the wire fasteners of the new drill pipe, resulting in leaks, snaps, and loosening, and so on. 2. In the use of drill pipe for a drilling, should be first “grinding new buckle”, which consists of, first smeared with silk buckle oil, and then use the drill rig full torque, and then open the buckle, and then smeared with silk buckle oil and then open, and so on for three times, you can avoid the new wear and buckle. 3. As far as possible to maintain the drill pipe under the ground and on the ground in a straight line, so as to avoid part of the side of the wire buckle force and cause unwanted wear and tear, or even jump buckle, pay attention to the rig anchored to avoid the construction of the force to move is very important. 4. The buckle...

What are the Basic Maintenance Methods for Water Well Drilling Rigs

  Cleaning: After every day's operation, clean the mud, oil, and other debris on the rig in time to keep the rig clean. Checking lubrication: regularly check  the lubrication points to ensure that the lubricant is sufficient and the grease is clean. Fasteners check: you can check whether the bolts and nuts of each part are loose and tighten them in time. Hydraulic system checks: you can check whether the hydraulic oil level is normal, whether there is no leakage phenomenon, and whether the hydraulic oil is clean. Lubrication system maintenance: regular replacement of lubricating oil, grease, cleaning oil filter, and oil tank. Hydraulic system maintenance: regular replacement of hydraulic oil, cleaning hydraulic filter. Cooling system maintenance: clean the radiator, and check the coolant level. Transmission system maintenance: check the tightness of the transmission belt, and replace the worn transmission belt. Electrical system maintenance: check whether the line is firm...

Use and maintenance of drill bits

Use and maintenance of drill bits: 1. Choose a suitable drill bit:  Before using a drill bit, it is necessary to select the appropriate type and specification of drill bit based on drilling conditions and needs. 2. Installing the drill bit:  When installing the drill bit, it is necessary to ensure that the connection between the drill bit and the drill pipe is firm, and to correctly install the cutting teeth of the drill bit. 3. Maintain appropriate drilling speed and pressure during the drilling process:  Excessive drilling speed and pressure can lead to premature wear and damage of the drill bit, while too small can affect drilling efficiency. 4. Regular inspection and maintenance:  Regularly check the wear of the drill bit and replace severely worn components in a timely manner. At the same time, it is necessary to regularly clean and lubricate the drill bit to extend its service life. 5. Storage and preservation:  When storing and preserving drill bits, it i...
