... plugs of the subsequent stages at the originally designed depth. To avoid leaving the target lateral unstimulated after casing deformation incidents, operators would have to perforate the entire remaining lateral and conduct multiple fracturing treatments with diversions; however, high uncertainty...

...Well Configuration The overall drilling and well placement strategy has significantly changed during the past two decades. With the development of new technology, most wells in moderate to low permeability reservoirs are drilled horizontal with extended laterals, sometimes exceeding 10,000 ft...

..., there can be cases in which there is very little consistency between directional driller performance on the same rig. For example, the day shift may prefer to orient toolface while tagging bottom and carefully manipulate Diff P to steer, then later ramp up Diff P to increase ROP once on bottom. While...

... are based on the operations performed on Well-A: The new multilateral completion technology allows lateral access for improvements in the production optimization approach and the ICD operation. Multilateral completions can address many challenges that occur over the well's life. Technology has...

... Sliding sleeve technology utilized in hydraulic fracturing operations has historically provided an effective means for stage isolation in cemented and open hole laterals. With the option to open or close sleeves installed within a wellbore, operators can regulate and control the composition...

... and tools. The drilling time was improved from 30-50 minutes per stand to 18-25 minutes per stand in the fast drilling part of the lateral interval (about 1500 meters). Furthermore, the fluctuation of the drilling parameters were reduced to two-thirds compared to previous wells. The drilling team completed...

... gauges (PDHGs) installed for pressure and temperature monitoring, while the horizontal lateral functions as an oil/gas producer. Combining the observation and producer wells into one well results in cost savings and maximum reservoir recovery and management. In addition, the capability to access...

... of minimum sand transport flowrates. With the well shut-in, a leak detection survey was conducted while running in hole and a faulty GLV identified. With the well flowing comingled from both mainbore and lateral 2, data indicated a mixture of oil and water being produced, along with significant quantities...

... MSDT subs were deployed with the 5.5" liner creating 159 and 183 laterals, respectively. The MSDT was integrated with Inflow Control Device (ICD) screens and swellable packers to constitute the total completion in the reservoir. Following the product development, full-scale testing programs...

.... In refracturing, PGT has tremendous benefits because the energetic propellent can help the new perforations breakdown and compete with the existing broken down and eroded perforations. Additionally, unique tracers are injected at several known cluster depths throughout the lateral. Any returns of the unique...

.... The paper discusses diverter application across the laterals, and the measured effect on the fracture system impedance across different types and volumes of diverter. Post-stimulation diagnostics (radioactive tracers and chemical tracers) along with production data are incorporated into the analysis...

... multilateral technology has extended the production life of these fields by continuing to evolve to meet the demands of increasingly complex subsea applications. Over this history, multilateral applications have evolved from dual-laterals with standalone screens and commingled flow to tri-lateral and quad...

This gives rise to the challenge of flowing back wells in an economic manner without compromising safety and the environment; all the while ensuring excellent well deliverability. By utilizing subsurface smart well completion inflow control valves, individual laterals are flowed...

To leverage historical data in new projects, metrics are created as a benchmarking tool. The case studies in this paper include metrics such as the Known Lateral Contribution (KLC...

... Abstract Steerable drilling motors still dominate US shale drilling applications. Shale well construction is commonly planned with monobore vertical, high dogleg-severity (DLS) curve and lateral sections. Limitations arise in each portion of the wellbore because one single bottomhole assembly...

... temperature gas bearing formations. There were also washed-outs & high "dog-legs" along their wellbores, due to constant geo-steering required to keep the laterals within the hydrocarbon bearing zones. These factors introduced challenges to deploying the conventional MSF completion in these laterals. Due...

... Abstract This paper deals with the case of using the production surveillance inflow tracer-based method in one of multi-lateral wells located in West Siberia. Tracer systems were placed in the well during the well construction by horizontal side tracking, and multi-stage hydraulic fracturing...
