An infill drilling project was undertaken in the Eunice Monument South Unit (EMSU) to help balance the current water flood and strategically place producers and injectors into a smaller spacing and configuration. Past developments and treatments to better flood the units were initiated in 1996 to characterize the reservoir and improve the flood conformance. Knowledge gained led to the implementation of the infill drilling EMSU project and identified the criterias needed to offset the problems that would be faced. Crossflows and high water influxes would be encountered, and determination of a system to gain the best possible zonal isolation during the primary cementing operations was established in the planning process. Follow-up ultrasonic cement evaluation logs were run to determine the performance and integrity that was achieved. Controlled injection profiles in the newly developed injection wells and the ability to control the placement of fracture stimulation in new producers were reflected in the well's performance.
