esting of the first discovery well. Usually the test string sands up, which may make it difficult to conclude the test. In spite of the evidence of sand problems during the test, the presence of sand alone can not reveal the nature of sand production. Special tests such as the one illustrated in
figure 3.24, are needed to gain more information and to establish the critical sand-free oil rate. These tests can be combined with empirical correlations to correlate density and sonic logs to mechanical properties and to sand production tendencies (Stein et al. 1974; Stein 1976). Operators have four alternatives to control sand production:
1. Reduce producing oil and gas rates below the critical rate for sand production. This approach
requires identification of sand production characteristics and a test to establish the critical
production rate. In addition it requires special completion and production practices, including:
(1) high perforations density - 8 to 12 shots per foot - (2) long perforation intervals; (3)
perforating only selected intervals with high degree of sand cementation; (4) completing and
treating the wells with nondamaging fluids that do not reduce the stability of the sandstone; (5)
avoiding sudden flow rate changes or "surge flow."
2. Prevent sand production mechanically by a screen or gravel pack thereby retaining formation
sand in place around the wellbore.3. Chemically consolidate the formation sand near the wellbore using resinous materials. The resin glues sand grains together, forming a stable, consolidated, permeable rock mass near the wellbore. If successful, the resin should not impair permeability by more than about 10%, although considerable damage may result if the resin is incompatible with clays and minerals in the formation, or if the injection sequence was not performed properly. Details of sand consolidation techniques are described in many publications, such as ones by Strohm et al. (1967), Hamby and Richardson (1968), and Richardson and Hamesting of the first discovery well. Usually the test string sands up beth graves forex, which may make it difficult to conclude the test.
