C) type of SSSV closing mechanism (ball, flapper, etc.):
d) requirement for internal self-equalizing capability:
e) requirement, if any. for holding the SCSSV open without the use of the primary operating source (temporary or permanent lock-open system);
1) requirement, if any, for providing control fluid communication from the SCSSV to any other subsurface device (e.g. a through-tubing retrievable secondary valve):
g) requirement, if any, for providing pump-through capability:
h) requirement, if any, for a redundantlindependent back-up operating system;
I) requirements, if any, for minimal leakage (in accordance with 6.7.2) during functional testing.
5.3 Well parameters
The following characteristics shall be specified as applicable:
a) well location (land, platform, subsea):
b) size, mass, grade and material of the casing and tubing:
C) setting depth (maximum required for application) and control system parameters (control fluid type/properties, supply pressure, supply line(s) and connection rating(s), etc.):
d) casing and/or tubing architecture, Irajectory. deviations, maximum dog leg severity:
e) restrictions through which the SSSV shall pass and restnctlons/profiles through which the SSSV service tools/accessories shall pass:
f) requirement, if any. for passage of additional lines (electrical, hydraulic), between the valve OD and the casing ID. if applicable.
5.4 Operational parameters
5.4.1 SSSVS
The following operational parameters. as applicable, shall be specified for the SSSV:
a) rated working pressure:
b) rated temperature range:
C) if applicable, maximum allowable pressure drop at maximum flow rate through SSSV:
d) loading conditions. including combined loading (pressures, tension/compression, torque, bending) and the corresponding temperature extremes anticipated to be applied to the valve:
e) well stimulation operations, including its parameters, such as acidizing (give the composition of the acid), the pressure, the temperature, the acid flow rate and the exposure time, as well as any other chemicals used during the stimulation:
f) sand consolidation and fractunng operations, including sandiproppant description, fluid flow rate, proppantlfluid ratio or sand/fluid ratio, chemical composition, pressure and temperature:
g) well-servicing activities through the safety valve: size, type and configuration of other devices to be run through the valve, if applicable.
