... Swellable elastomer packers are the preferred choice for openhole zonal isolation for many applications due to their cost-effective and interventionless deployment. For drilling long laterals, customers prefer to drill in oil-based muds (OBM) because the OBM acts as a lubricant and helps...

... inside a limited entry liner that is segmented into stages or intervals by openhole programmable interventionless packers (Mendes et al. 2014) all run in a single trip and with no pipe manipulation required while stimulating. It furthermore leaves behind a robust lower completion system for the life...

... stimulation techniquesdidn't help in achieving good results. To effectively remove the suspected damage a coiled tubing based solution was implemented which involved the application of Inflatable Straddle Packer tool. It provides pinpoint accuracy for conventional, horizontal and multilateral stimulation...

... completion design was prepared, separating the ca. 17,500 ft long reservoir section into an inner zone and an outer zone. The design includes a novel combination of two different types of open hole packers: Two mechanical packers and one swell packer. The open hole packer solution was preferred to a cemented...

... hydrostatic-set packers. Using inflow control devices (ICDs) in this completion design allows a uniform inflow across the entire horizontal wellbore, which mitigates early water or gas coning into the wellbore. A newly designed ICD has been developed and field-trialed successfully that eliminates the need...

.... To achieve this, the downhole test set up comprised of a series of stacked retrievable packers with tail pipes separating successive test intervals. The tailpipe of each packer was equipped with wireline nipple profiles and an external gauge carrier with multiple gauges featuring acoustic telemetry...
