Enhancing of Sand Control Designs to Deduct Cost of Oil Well Production Using Otakikpo Marginal Field, Rivers State Nigeria

Dougha Preye

Abstract

The aim of this research is to improve sand control strategies and reduce cost of an oil well production using Otakikpo marginal field, Rivers State as a case study. In this research four wells A, B, C, and D with sanding problem were used as case study and the sand management methodology applied. A sand analysis was carried out on the wells to indicate the well with highest cumulative and average sand production, high percentage BS&W and high oil rate from the analysis well B had the highest cumulative and average sand production of 2009pptb and 41.8ppbt respectively and produced the highest %BS&W of 74%.In this research, the reservoir pressures were recorded for each well and the wells were flowed at a minimum of four different flow rates to estimate other relevant data. Gas well deliverability test is used as a model, which relates the Gas flow rate ratio (Y) to pseudo-pressure ratio (X) for the respective wells. For each approach a graph is plotted based on gas flow rate ratio (Y) and pseudo-pressure ratio (X) data generated. From my observation ESS tends to increase as the gas is being produced while the EGP with time decline gradually as gas is produced, hence; ESS provides larger inflow area with less friction during gas production thereby enhancing the well productivity. Well D the highest oil rate of 974bopd additional $14,952.2 per day. Well Boil rate increases by 41.3% to 475bopd causing an additional $8,313.5 per day. The sand management strategy has therefore led to increase in gains from investment, avoidance of high cost of sand control reinstallations, losses from shut-in of wells total loss of well has prolonged the economic development of the reservoir. Based on the findings, the study recommended additional test should also be carried out in a fractured reservoir to determine its effectiveness and performance, two detectors should be placed along each flow line and separated over a small distance to improve sand monitoring reliability.
