Who Should Attend?
All petroleum professionals involved in
drilling and completion of wells, especially drilling, reservoir,
completion, and production engineers and development geologists.
Agenda:
8:30- 9:15 am: Registration, Welcome and Introduction
9:15–10:15 am: Geomechanics Applictions for Sand Control: (Dr. Lewis Lacy, Core Laboratories).
This
seminar presents how laboratory-based rock mechanics is used in the
petroleum industry to solve field problems, calibrate logs and to
increase reservoir recovery associated with sand control.
Laboratory-based rock mechanics concepts and equipment are explained
and related to wellbore stability applications in the petroleum
industry including horizontal and deviated wellbores. There are five
laboratory based techniques that will be reviewed. These tests identify
the weakest parts of the formation, determine when sand control is
necessary, determine the critical draw down pressures and identify when
sand production is initiated, calibrates logs for sand production and
provides critical data for sand control.
10:15 am – 10:30 am Coffee Break
10:30 am – 11:30 am: Sand Screens: (William K. Ott, P.E., Engineering Consultant)
There
are various types of sand screens used for sand exclusion including
conventional wire-wrapped, prepacked and premium screens. Wire-wrapped
screens offer an alternative for retaining gravel in an annular ring
between the screen and the formation. The main advantage of welded or
wire-wrapped screens that employ stainless steel wire is that they are
more erosion and corrosion resistant than slotted pipe. Prepacked
screens are a modification of existing wire-wrapped screens and
represent the modular gravel pack. They consist of standard screen
assembly with a layer of resin-coated gravel placed around it. Premium
screens include a new generation of screens developed to address
perceived problems with stand-alone completions such as plugging and
erosion before wells are depleted.
11:30 am – 12:30 pm: Frac Packs: (Mladen Ruzic, Baker Oil Tools GCR)
Frac
packing has been a popular sand control technique since the early 1990s
and provides highly reliable completions aimed at enhancing the
productivity of gravel packed wells. The technique consists of
incorporating a tip-screenout hydraulic fracturing treatment as part of
the gravel packing procedure, thus stimulating the well. Almost all
frac pack treatments have been performed in cased holes. However, in
high performance wells where perforations are the dominant restriction
to flow, an open-hole completion is preferred because perforations, and
thus flow restrictions are eliminated.
12:30 pm Lunch
If this event is specific to a Committee, select the committee here, so the event will ONLY be listed on that committees calendar.
