Ahmad designed and led the implementation of various automated engineering workflows in the area of virtual metering, production and reservoir surveillance and automatic well model building and calibration, for which he was granted two patents from the US patent office. Prior to joining Schlumberger in 2017, Ahmad worked with Saudi Aramco for 15 years and served as a technical consultant and a project manager in various oil and gas design and optimization projects that covered diverse production engineering areas such as: integrated asset modeling, flow assurance, advanced completions and artificial lift. He is currently holding the position of “Product Champion” for the multiphase flow simulator: PIPESIM. Presenter: Ahmad Shammari, Senior Petroleum Engineer | Asker, Akershus, NorwayĪhmad Shammari is a senior petroleum engineer with 18 years of experience in oil and gas production optimization and digital oil field solutions. Hence, equivalent length does not play a role in determining the temperature profile.Date and Time: 10:00AM-11:AM CT | Wednesday, February 3 rd 2021 It is only based on the straight length or more precisely on the surface area exposed to the temperature gradient. Is this a correct approach?Ĭhange in temperature profile is never considered based on equivalent length.
If PIPESIM gives inaccurate temperature profile, will it not affect the pressure drop too?Īlso, since we are entering the equivalent length into the program for pressure drop calculation, the temperature change too will take the longer equivalent length into the calculation instead of the actual length.
I believe PIPESIM gives a better results for pressure drop calcs, but the pressure drop however, is a function of temperature.
When it comes to temperature profile, which program (HYSYS and PIPESIM) gives a better results? I have observed that for PIPESIM, regardless of the pipe length, the temperature tends to move quickly towards to the ambient temperature which i have specified compared to HYSYS.
