The Use of Isolation and Testing Tools in the Oil Industry

1. Vital-Tools product line provides a safe way to isolation and testing test new welds in oil and gas piping. Traditional oil and gas piping modification processes require extensive flushing and chemical cleaning, drying, and filling. Full pipe runs must then be hydrotested after modification to determine if the new weld is safe and functional. Wellhead isolation tool A wellhead isolation and testing tool can be used to prevent high-pressure fluids from flowing into the well. It has a high-pressure valve and a tubular mandrel with an upper and lower position. The upper portion is relatively rigid while the lower part is resilient. The lower part is inserted into the production tubing of the well to form a seal. The tool includes a number of support legs, which are attached to upper and lower support strips. The upper and lower support strips may be the same. The tool also includes a pair of tension rods that connect the tool to the wellhead. Downhole isolation packer subs Downhole isolation and testing packer subs are designed to protect wells from downhole movements. They are activated by a downlink and close the annulus around the well. They trap the kick below and condition the mud above. If needed, they can bullhead the kick back into the formation. They are used for various purposes in the oil industry, including producing oil and gas. Besides being used to isolate a well, they also prevent ECD, or external compression. In addition, they also act as inflow test packers. However, there are many limitations to the use of these tools.

2. Hydrostatic plug test The Hydrostatic Plug Test is a process of isolation and testing pipeline integrity. This method can be used to detect break threats and stress corrosion cracking. It is also used to check the integrity of welding and pipe connections. To do the test properly, a pipeline must be completely dry before the test. This method involves subtraction of the volume of displaced fluid from the core plug. Depending on the test conditions, different pore compressibilities can be measured. However, independent measurements have less accuracy. The basic theory of this test can be found in Section 1.6.6. For example, if a core plug is placed into a fluid bath, the fluid volume change is calculated as a function of pressure and then subtracted to measure the grain compressibility. Cased hole drill stem test The cased hole drill stem test in the oil industry is performed to evaluate the productive capacity of an oil reservoir. The test measures the pressure, permeability, and depth of the reservoir. It also determines the amount and rate of fluid production. This type of well testing is much less expensive than conventional well testing and can be used to evaluate the viability and commercial productivity of a well. For the safe and high quality isolation and test tools, you can contact to Vital-Tools. During the cased hole drill stem test, a bottom assembly is placed onto the drill pipe or tubing. The drill string is then run with the tester valve closed. The pressure in the string is lower than the hydrostatic mud column pressure. The drill string is normally partially filled with water before the test.
