Heightened the Productivity of an Eruptive Petroleum Well with Two Reservoirs by Jet Pump and Infill Well

In a confidential field, several producing wells exist, including Well Y, which has two reservoirs, S1 and S2. Production initially occurred from reservoir S1, but it has since ceased. Although Well Y is unable to access reservoir S2, which possesses favorable petrophysical characteristics, optimizing production at Well Y requires implementing an effective optimization technique. With reservoir S1 non-viable, the focus shifts to optimizing production at both the S1 and S2 scales through the same well. Key objectives include justifying the optimization method, designing completion strategies, improving production, and developing economic assessments. This study employs PIPESIM, Prosper, and Excel software, along with completion and PVT (Pressure, Volume Temperature) data, to follow an established methodology involving infill drilling (horizontal well) and activation via a jet pump. Results indicate that after activating reservoir S1 with the jet pump, Well Y could produce 4404 STB/d at a pressure of 3581.55 psi. Decline curve analysis suggests a production lifespan of 10 years, yielding an estimated total output of 8.70 million barrels. The optimization and maintenance costs are projected at $69.98 million, while hydrocarbon sales revenue is estimated at $780.91 million, resulting in a gain of $140.31 million and a payback period of approximately 8 months and 19 days.
