2.3 GRAVEL PACK

Material for the gravel pack around the riser pipes and screens shall be washed gravel composed of hard, tough, durable particles free from adherent coating. Limestone, dolomite, or carbonate materials will not be acceptable materials. The gravel pack material shall contain neither detrimental quantities of vegetable matter nor soft, friable, thin, or elongated particles. The gravel pack shall meet the following gradation requirements:

U.S.Standard Percent by Weight Sieve No.

Passing 3/8 inch 100 No. 4 50-90 No. 8 12-28 No. 16 9-15 No. 20 0-8

Materials shall be uniformly graded between the limits specified above.

All points on individual grading curves obtained from representative samples of gravel pack material shall lie between the boundary limits as defined by smooth curves drawn through the tabulated grading limits plotted on a mechanical analysis diagram. The individual grading curves within these limits shall not exhibit abrupt changes in slope denoting skip grading, scalping of certain sizes or other irregularities that would be detrimental to the proper functioning of the gravel pack.

The gravel pack shall have a minimum thickness between the screen and drilled hole sidewall of 6 inches, as indicated on the drawings.
