API RP 5SF

Anotácia textu normy API RP 5SF :

The primary focus of this standard is to evaluate connection performance under the structural loads that typically occur in multifractured horizontal wells (MFHW). This standard may be used in conjunction with API 5C5 to subject the connection to structural loading before subsequent sealability evaluation.This standard defines tests that may be used to determine the performance of threaded casing or tubing connections for use in multifractured horizontal wells (MFHW). This standard defines experimental loading conditions intended to simulate the various stages of MFHW construction and use—installation of casings, stimulation of surrounding formation, and production of hydrocarbons. Dynamic effects from such factors as thermal shock, vibration during running/rotating, and hydraulics are beyond the scope of this standard.This standard does not address erosion or metallurgical impacts such as corrosion or hydrogen embrittlement. This standard also does not establish a singular testing program or acceptability criteria. Not all the test program elements (TPEs) presented in this standard may apply to all MFHWs; consequently, this standard provides flexibility in tailoring a testing program for the specific, anticipated field loads of a given well (or group of wells). End users are ultimately responsible for determining whether an evaluation program assembled from the TPEs presented in this standard is appropriate for a given set of field conditions. This determination will likely be based on historical practice, local regulatory requirements, and specific well conditions. See more
