c) The potential for corrosion in pipelines
Scenario: You are working on an offshore oil platform and have been tasked with analyzing the recent increase in SW Cut. The platform's production manager has expressed concerns about the impact on production economics.
Task:
**Potential Causes for Increased SW Cut:** 1. **Reservoir Depletion:** As the oil and gas reservoir is depleted, the pressure within the reservoir decreases. This can lead to increased water production as water moves into the lower-pressure areas. 2. **Water Influx:** The reservoir might be experiencing water influx from surrounding formations. This could be due to fractures or other geological factors that allow water to migrate into the reservoir. 3. **Production Well Issues:** A problem with a production well, like a damaged casing or a poorly cemented wellbore, could allow water to flow into the wellbore and be produced along with the oil and gas. **Impact on Production Economics:** * Increased water production leads to higher treatment and disposal costs. * The higher SW Cut reduces the amount of oil and gas produced, impacting revenue. * Increased water production can lead to operational issues, such as pipeline corrosion. **Actions to Address the Issue:** 1. **Optimize Production:** Review and adjust production strategies to minimize water production, such as optimizing wellhead pressures and implementing water shut-in periods. 2. **Investigate Water Influx:** Conduct geological and reservoir studies to identify potential sources of water influx and implement remedial measures like plugging water zones or installing water control devices.
