“…2,3 Attaching shunt tubes to the screen OD was included as part of the screen design to help meet the challenge associated with gravel packing the screen/casing annular sections of long intervals. 4 The goal was to propagate fractures across most/all of the reservoir height with high pump rates (27 to 40 bbl/min) and gravel-pack the entire screen / casing annulus with the help of shunt tubes.…”

AbstractConocoPhillips is developing the Magnolia field with a Tension Leg Platform (TLP) in 4,674 ft of water at Garden Banks block 783 in the Gulf of Mexico. The wells target multiple zones resulting in complex directional wells with 50°-60° maximum hole-angles. The wells are completed using dry trees from the TLP and are producing primarily from massive, fine-grained, Pleistocene-aged reservoirs.These reservoirs require sand-control to prevent sand production at the expected drawdowns planned during the life of the wells. To help ensure high rate, long life completions, the producing zones are frac-packed. The average perforated interval during the initial completion program was 310 ft with a maximum perforated interval of 571 ft.The typical production casing string for the wells consists of 10-3/4 in. casing with an 8-1/16 in. production liner. Drift diameter through the tapered production casing is 9-1/2 in. and 6-1/2 in. respectively. The 6-1/2 in. drift diameter allows using common size screens and packers. The wells are generally completed with a 4-1/2 in. x 3-1/2 in. tapered tubing string.Premium screens with shunt tubes are used on the wells due to the long deviated intervals.The "frac-pack" stimulation treatments are pumped at rates of 27 to 40 bbl/min with a viscoelastic surfactant carrier fluid. Washpipe conveyed downhole pressure and temperature gauges and radioactive tracers are used to help analyze the treatment results.This paper will discuss screen selection philosophy in silt/very fine sand reservoirs, carrier fluid selection, perforation strategy, and ability to frac across shale intervals. The paper will also cover the effectiveness of achieving a frac-pack with premium screens with shunt tubes, based upon downhole pressure, temperature, radioactive tracer information, and revised operational practices that resulted in zero to negative skin completions across long, perforated intervals that continue to produce sand free after extreme reservoir depletion.

AbstractSince its introduction, over 700 alternate path sand control completions have been implemented around the world ranging from single zone cased hole gravel-packs to multi-zone fracpacks and fibre optic (DTS) enabled open hole horizontal completions. Over the last six years, the alternate path system has been field proven to provide high reliability in achieving complete packs as well as additional features allowing simultaneous cake cleanup, shale bypass and other contingencies that enable "doing it right the first time" in deep-water/subsea completions where interventions tend to be economically and logistically prohibitive.This paper provides a critical review of those completions, capturing both successes and failures, along with the lessons learned in their design, execution and evaluation in relation to completion efficiency in sanding reservoirs. Furthermore, it details future development work and enablers that will allow the use of alternate path technology as the mainstay of intelligent well solutions, geometrical design improvements to provide optimal aspect ratios in the wellbore and its applicability in conjunction with water packing.

“…As explained in previous papers 11,12,8,14,15 , shunt tubes attached to the outside of the screen are invaluable in bypassing annular bridges and obtaining complete frac-packs and gravel packs. Extending this concept, David Bryant 9 , developed an isolation packer with shunt tubes (see Figure 2) which can be used to isolate the annulus in a gravel pack and provide a means for shutting off water later in the life of a gravel packed well.…”

fax 01-972-952-9435. AbstractSelective gravel pack completions of multiple zones present the oil industry with major challenges and expenses. Current practices have two key problems associated with them: (1) they are limited to zones separated by 30 to 50 feet (depending on the treatment type) due to the length of the assemblies (2) they have proven to have a higher risk of installation failure. This paper describes equipment and procedures for gravel packing multiple zones in a single completion with total zonal isolation for spacing as small as 5 feet. Zones can be produced either separately or co-mingled. Risk of execution failure is significantly lower than with conventional stacked packs. Production data is presented which verifies complete zonal isolation, improved productivity, and reduced costs from this technique.
