“…Several researchers reported that to obtain a successful gravel pack for highly deviated and horizontal wells the fluid flow in screenwash pipe annulus also must be minimized. [12][13][14][15] During the Alpha-Beta wave building up and propagation process, the gravel will be deposited and the fluid will flow along the least resistance path. Figure 1 is a schematic of the Alpha wave building up process.…”

fax 01-972-952-9435. AbstractGravel packing long horizontal wells presents many challenges to completion operations. The accurate calculation of Alpha wave dune height under dynamic wellbore conditions is on the top of the list. Alpha wave dune height is critical during job planning and the afterward successful gravel placement execution. Excessive Alpha wave dune height is the cause of many early time screenout and job failures. The job parameters, including wellbore geometry, pump rate, leakoff and leakoff control, fluid density and viscosity, gravel particle size and geometry, liteProp and conventional gravel, wellbore temperature profile, bottomhole pressure distribution, will all have impact on Alpha wave height.This paper investigates and summarizes several particle transfer models, analytical and empirical ones, their applications in Alpha wave dune height calculations, their limitations and effective application windows. The paper also provides dynamic Alpha wave height calculation methodology to account for dynamic bottomhole conditions, especially the fluid leakoff to formation and to screen wash pipe annulus, bottomhole in-situ gravel concentration, and their impact on Alpha wave dune height calculation. The sensitivities of these models under different job conditions are also studied.Several job designs and application histories are presented in the paper to demonstrate the application of different particle transport models. Guidelines are provided for operators to make proper adjustment when an undesired condition is present during gravel placement.

Although extended reach and horizontal wells in deepwater fields have presented many difficult challenges, operators have been willing to accept the challenges because of the substantial net reserves that the deepwater fields offer. Unfortunately, although promising new technologies that target the more extreme conditions inherent to deepwater completions have been introduced, many operators have hesitated to try them because they lack proven track records. Fortunately, this has not been the case with one operator, and this paper will discuss the innovative technologies that were employed to successfully perform two "firsts" in gravel pack completions in complicated wellbore scenarios in a deepwater subsea field.The first job is the longest deepwater horizontal gravel pack (HZGP), run in Brazil. 75,000 pounds of gravel was placed in a 2,730-ft openhole section in 2,621 ft of water from the Ocean Alliance rig.The technologies that were instrumental in the success of this completion included special packer technology, a multi-position weight down tool with a HZGP pressure maintenance assembly, and a new type of sand control screen. Despite the long slant section (6560 ft @ 60 degrees) and openhole length, installation of the sand control completion was smooth, never reaching more than 10,000 pounds of drag.The second job used a realtime operations (RTO) data acquisition and visualization system during a gravel pack procedure. The system employs advances in traditional data management and networking to allow the personnel at the wellsite as well as all remotely stationed personnel to monitor critical well parameters so that immediate decisions on procedural changes can be made. The system allowed the service personnel and operator to monitor the job's execution and adjust pumping parameters as needed. This job illustrates the enhanced capabilities that can be gained from adapting innovative techniques to traditional procedures. Producing the fields is a massive undertaking and will add 30% to the current one million BOPD output from the area. The development project includes 55 wells of which 22 will be horizontal producers, 2 multilateral producers, 8 horizontal injectors, and 8 piggyback injectors. The 15 wells already in production will be recompleted.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractMultilateral technology offers the oilfield many advantages since it can deploy a completion system that can mechanically connect several lateral wellbores to a parent wellbore and will allow selective or commingled production. In most cases, these capabilities can provide more cost-effective well construction since reservoir exposure from one wellbore is increased. These advantages are particularly beneficial in offshore and deepwater environments where slot and/or subsea templates are limited, and rig costs are substantially higher. Because of the flexibility of this technique and its capability to offer various production options, it helps to mitigate the risks previously associated with directional/horizontal wells in new field developments as well as in revitalization of mature fields. Because of continual improvement in drilling techniques and the increase in field success, multilateral technology continues to gain in popularity; however, as with all completion techniques, it must be remembered that existing completion options must be evaluated for each case, and if needed, adapted to meet specific reservoir objectives and concerns. This paper will focus on considerations, applications, and benefits of specific tool configurations developed for interfacing sand-control fracturing stimulation with multilateral technology. The techniques discussed include existing, modified, and conceptual completion methods that can be deployed into multilateral field-development strategies. The strategies address window selection, junction isolation, fluid loss, debris management, and lateral accessibility. Several completion sequences, which include a new Technology Advancement for Multi-Lateral (TAML) level 4 single-trip, gravel-pack methods and installation of expandable screen technology, will also be presented.
