Introduction of API 5L X56 Sour Service Pipes

Managing Sour Service in Oil Export and Onshore Pipelines: A Case Study

Thirteen extended H2S excursions (19.64 mg/l maximum) above the Standard Operating Limit (SOL, 6.7 mg/l), recorded for the export and onshore pipeline Msystems in January 2010, contravened the Pipelines Safety Regulations (PSR) 1996 and triggered an assessment to determine the safety of continued operation in a sour service condition. Sampling and monitoring results were assessed and the pH and H2S partial pressures were found not to align with any of the ISO 15156 SCC regions of environmental severity (0, 1, 2 and 3). Both pipelines were, therefore, considered safe for continued operation as long as pH remained near-neutral above 6.5. Since pH was found to be the main driver for SSCC risk, pH analysis has been recommended for every pig receipt with H2S and CO2 excursions being the main triggers.

Also, the high risk of HIC should be mitigated by maintaining pH at near-neutral levels. Very low H2S levels have been achieved by pigging, biociding and scavenging and low corrosivity by adequate corrosion inhibition. The weld root hardness of the export pipeline (295 HV10) is out of compliance with ISO 15156 hardness requirements for operating in the SCC region 0 (275 HV10). Risk-based inspection (RBI) reviews are recommended to determine inspection techniques and frequencies appropriate for all susceptible weldments.

NACE TM0284 Test Solution

NACE TM0284 specifies either Solution A or Solution B. Solution A is acidified brine. Solution B is simulated seawater prepared in accordance with ASTM D1141.52. In either case, H2S is bubbled through the solution constantly throughout the test period. NACE TM0284 specifies test duration of 96 hours.

This export pipeline is not intended for sour operation and is therefore considered potentially vulnerable to Sulfide Stress Corrosion Cracking (SSCC), especially at the welds and hydrogen induced cracking (HIC) of the parent plate. The onshore receiving line was originally designed for sour operation. However, several chemical injection valves were later welded to various locations on this pipeline. As the welds were inadequate and no Post Weld Heat Treatment (PWHT) of the heat affected zone (HAZ) was performed Based on the tests performed, it is considered that the onshore pipeline is potentially at risk for SSCC at these welds. These pipelines experienced a large H2S spike in January 2010, exceeding the established safe operating limit (SOL) of 6.7 mg/L. This suggests that the H2S spike was caused by the following factors in combination with a pigging run that tended to increase the impact:

  • Increased H2S levels in reservoir fluids (in varying proportions from the five entrant pipelines) caused in part by SRB activity from water injection.
  • SRB activity within the pipelines (i.e. export and onshore) and topsides
  • Gas lift H2S concentrations. The very high severity of safety, environmental, and business consequences of the failure of these pipelines combined with an equally high probability of catastrophic failure under the current operating regime, represent a very high overall risk scenario.

Specimen Size

  • To conduct the SSC test, requires the following sample sizes:
  • Pipe - upto 2" OD - 200mm long
  • If the pipe is more than 2" OD pipe - 100mm long sample size is required
  • Number of pieces to be tested upto 88mm thick/dia - set of 3 pieces to be tested
  • Number of pieces to be tested more than 88mm thick/dia - 5 pieces to be tested

Detailed Report

A detailed written report upon completion of each test. Each report includes a description of the test sample that was received, the test procedure that was used, and the pH values of the test solution before exposure and after the exposure. The test bars are cut into sections and examined under a microscope for hydrogen-induced cracks. The dimensions of any such cracks are recorded and used to compute the values in percentage for Crack Length Ratio (CLR), Crack Thickness Ratio (CTR) and Crack Sensitivity Ratio (CSR).

Annex H
(normative)
PSL 2 Pipe Ordered for SOUR Service

H.1 Introduction

This annex specifies additional provisions that apply for PSL 2 pipe that is ordered for sour service [see 7.2 c) 51 ] .

NOTE The consequences of sudden failures of metallic components used for the oil and gas production associated with their exposure to H2S- containing production fluids led to the development of NACE MR0175/ISO 15156-1[21] and subsequently EFC publication 16[13] ISO 15156-2 used those sources to provide requirements and recommendations for materials qualification and selection for application in environments containing wet H2S in oil and gas production systems. Carbon and low alloy steels selected using ISO 15156—2 are resistant to cracking in defined H2S containing environments in oil and gas production but are not necessarily immune to cracking under all Service Line conditions. Different service conditions might necessitate the alternative testing that is dealt with in ISO 15156—2:2003, Annex B. That annex specifies requirements for qualifying carbon and low alloy steels for H2S service by laboratory testing.

It is the purchaser’s responsibility to select the carbon and low-alloy steels suitable for the intended service.

H.2 Additional information to be supplied by the purchaser

f) chemical composition limits (see Table H.1, footnotes c), d,) e), f), i), j)and k);

g) frequency of hardness testing of the longitudinal seam weld of HFW or SAW pipe (see Table H.3);

h) SSC test for manufacturing procedure qualification (see Table H.3);

m) magnetic particle inspection for laminar imperfections at each pipe end face/bevel (see K.2.1.4);
