We recently added new rods and made some logic improvements to the torque calculations of RODSTAR. Details follow:
“ProRod” Continuous Rods
We added new continuous rods made by ProRod in Canada. These new rods are available in 1/16 inch increments and in two grades: ProRod 620 and 790. Figure 1 shows the new rods on the RODSTAR rod string entry window.
Norris 96 and new 1¼ inch Norris 97 Rods
We also added the new Norris 96 rod type along with the new 1¼ Norris
97 rod type. Figure 2 shows the new Norris 96 rods (which also have a 1 ¼
inch size) in RODSTAR’s rod string input window.
The Norris 96 rods have a tensile strength of 135,000 psi as compared to the
Norris 97 at 140,000 psi. There are two main reasons Norris came up with the
1 ¼” rod size:
Support for the new CBALANCE
The new version of RODSTAR also adds support for the new version of CBALANCE that uses XML for saving and importing files. See below for more information on the new CBALANCE.
Tensile strength field now shows value for high strength rods
In the new version of RODSTAR the output report now shows the tensile strength of all rods including non-API high strength rods instead of showing “NA”.
Enhanced logic for calculating counterbalance moment for minimum energy consumption
We discovered that in some rare cases the calculated maximum counterbalance moment for minimum energy consumption may not have resulted in the maximum possible every savings. This was remedied by extending the range of the search interval the program uses to locate the maximum counterbalance moment required for minimizing energy consumption. This gives more accurate results for balancing units for minimum energy consumption.
