A simpler practical standard for the common engineer is proposed as an alternative improvement. Though we rarely discuss pipe sizing in those terms, this is ultimately the basis for selecting the line size. Featured Articles Check out the latest featured articles.

1e of an international conference Subsea Controls and Data Acquisition ' Do the economics favor a lower capital cost for shorter life, smaller diameter pipe 207 more up-front cost for a longer life. Also request to provide reference for these values. No one to date has come up with a more logical manner of establishing a design procedure for handling this type of fluid flow.
Sheriff's Encyclopedic Dictionary of Applied Geophysics, fourth edition. Additional equations and methods for erosion prediction for wells have been published during the past couple of decades. Gravity Drop Pipework Velocity Control? Computational fluid dynamics CFD models with generalized sand flow and erosion simulation through any geometry are numerous 6.
This paper will introduce a method of choosing C-factors and allowable flow velocities based on several erosion models that represent erosion in wells more accurately than API RP 14E. Accuracy of these models, as well as erosion prediction in general, varies widely due to the chaotic nature of the erosion process. Community Apii Software by IP. These shortcomings in the standard have led to multiple new erosion models and guidelines. Production of Triple Superphosphate - posted in Ankur's blog.

Choosing Better API Rp 14E C Factors For Practical Oilfield Implementation - OnePetro
Salamah to ASME for further clarity: It's normally not worth the ai to analyze each local situation, so we gp on previous work based on outdated assumptions. API RP 14E includes an erosion standard that was established appi ago and has been regarded by many as being overly conservative for most production wells.
Posted 27 September - This means that you cannot reply to this topic. Therefore, that is why we all seem to be forced to follow API 14E recommendations. This paper presents an evaluation of API RP 14E and new alternative standards that account for sand concentration, allowable erosion rate, and flow geometry.
API RP 14E includes an erosion velocity guideline based on fluid mixture density and the assumption of sand-free flow.
Simpler alternate API C-factors also have been implemented for many years, based on field experience. Sign In Need an account? What happens in reality is that sand travels as a semi-slug! The worst case, of course. New Article Product Viscosity vs.
