Paper presented at the SPE Hydraulic Fracturing Technology Conference and Exhibition, February 4–6, 2020
Paper Number: SPE-199730-MS
... Since perforation friction varies by diameter to the fourth power, perforation diameter has always been an area of great interest for treatment designers and post-job modelers. Perforating service providers often provide entrance hole data as a function of perforation phasing; however, phasing...

Paper presented at the Abu Dhabi International Petroleum Exhibition & Conference, November 12–15, 2018
Paper Number: SPE-193223-MS
.... The original perforation methodology was to perforate with fixed static underbalance which applied to the first two wells with reasonable results on this area. Some of the challenges faced in the design and implementation of this job were the following: The minimum restriction constrained the type...

... analysis that provides effective results on production. In order to analyze and predict the well Productivity, it is necessary to perform an appropriate perforating analysis; this can be achieved integrating Petrophysics, Geomechanics, Reservoir and Production Domains. For an advanced Perforating design...

Paper presented at the SPE Latin America and Caribbean Petroleum Engineering Conference, April 16–18, 2012
Paper Number: SPE-153541-MS
...Perforating tool design During the perforating operation, two geomechanic parameters are changed around hole, which are the stress distribution and rock strength. The redistribution of stress in the vicinity of the well is caused by the absence of rock material in each of the holes generated...

Paper presented at the SPE EUROPEC/EAGE Annual Conference and Exhibition, June 14–17, 2010
Paper Number: SPE-130379-MS
.... Optimizing the stimulation process by perforating and acidizing in the correct way in such high-cost projects is a crucial issue for improved well productivity. This paper discusses how effective perforation design positively impacted the evaluation (Well Testing) and acidizing efficiency in such formations...

Paper presented at the SPE Annual Technical Conference and Exhibition, October 8–11, 1989
Paper Number: SPE-19749-MS
... Abstract A review of perforating regimes is presented followed by equations and tables which provide design guidelines for: - the minimum underbalance pressure necessary to provide clean perforations, and - the maximum underbalance pressure which can be tolerated without causing sand...

Published: 13 April 2022
... proved to be challenging with low viscosity slickwater owing to its limited transport capability. Computational fluid dynamics (CFD) has been used to model proppant transport in wellbore to improve perforation and fracturing design for achieving uniform proppant placement. However, traditional CFD...

... integrated and multidisciplinary process to ensure efficiency and mitigate risk. In particular, the process of perforating has called for careful design, planning and execution to prevent costly failures and maximize productivity over the life of the well. The perforating systems used in these environments...

Paper Number: IPTC-18155-MS
... stimulation treatments have failed due to the failure to initiate the fracture or to place enough proppant along the hydraulically created fracture due to an early screen-out caused by improper perforating design. This problem becomes more significant in the case of unconventional resources exploration...
