... completion was needed to cover the typical ~2000ft vertical gross pay with 4-5 zones. The fracture gel, proppant and fracture designs were then developed to meet the fracture length and conductivity requirements. Four wells were completed with excellent results yielding initial skins of −4 to −6 when skins...

... such as the Unified Fracture Design cannot be applied properly in the absence of a reliable value of permeability. Massive amounts of income ride on the optimum deployment of fractures. While core and log-derived permeability values are often employed, they are usually unreliable and irrelevant to the forecast...

... on location is limited to the capacity of the stimulation vessel. Stimulations on several wells showed suboptimal production rates which led to the conclusion that the Lower Cretaceous was not economically producible. An intensive study was carried out to evaluate all aspects of the fracture design...

... to the production from treatments using synthetic proppant in the same fields. This is an interesting finding because with the higher conductivity of synthetic proppants, a higher production rate is often expected. The paper discusses the hydraulic fracture design flaw that causes the discrepancy. Another...

... microseismic data for various fracture treatment designs. In this study, using both microseismic data and fracture/completion data; frac treatment production is estimated. The well database used for this purpose is comprised of fracture design parameters including treatment volumes, rates, proppant mass...

... Abstract In developing an encompassing well completion design, an integrated, comprehensive solution study was under taken for the Lower Tertiary, mainly Wilcox Formation in the Gulf of Mexico. The study included reservoir characterization, optimized hydraulic 3D fracture design and modeling...

Although microseismic event monitoring of fracture designs can help identify the geometry of the fracture stimulation...

... of Unified Fracture Design (UFD) which has been used to physically optimize and maximize the productivity index from a hydraulic fracture treatment. We have demonstrated in the past that for a given mass of proppant there is a specific dimensionless fracture conductivity, which we called the optimum...

... Valkó and Economides 1 , 2 introduced a physical optimization technique to maximize the productivity index. They introduced the concept of the dimensionless Proppant Number, N prop , given by: Abstract We have established the concept of Unified Fracture Design (UFD) to maximize...

... methodology was implemented in the design of 11 fractures treatments of 3 tight gas wells in South Texas. Results show that optimal fracture design might increase expected production by 9.64 MMscf/day with respect to design that assumes Darcy flow through the propped pack. The basic finding...

...) and initial reservoir pressure (Pr) in a manner similar to a Horner analysis. These two-reservoir parameters play a crucial role in the optimization of fracture design and rate prediction. For a tight gas sand, the amount of time required to reach pseudo-radial flow was thought to be quite large. However over...

... for the contractual production capacity of Oman's LNG plant that is currently under construction. In addition to using conventional fracture processes, engineers optimize fracture design by using both state-of-the-art dynamic gas-condensate reservoir modeling and fracture geometry modeling. They also analyze well...

.... Introduction Most of the work on fracture design has been based on guar gels or other "sand-banking" fluids. In these designs, the sand falls to the bottom of the fracture and fills the created fracture width. The controlling factor of the final fracture conductivity is the created fracture width...
