The production of sand at the onset of oil production indicated that depletion of reservoir pressure did not play any direct impact on the commencement of sand production in the reservoirs. Observed trends of sand production also showed that sand production was not influenced by the depletion of the reservoir pressure (Figure 2).Web

Even though sand production may increase the overall productivity especially in heavy oil, it also may cause other negative impact such as equipment erosion which can lead to loss of integrity that can eventually induce hydrocarbon leakage. Thus, safety factors need to be considered before deciding if sand production can be allowed in the well.Web
