All petroleum professionals involved in drilling and completion
of wells, especially drilling, reservoir, completion, and production
engineers and development geologists.
8:30–9:00 a.m. Registration
9:00 a.m. Welcome and Introduction
a.m. 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.
a.m. Sand Screens: William K. Ott, P.E., Engineering
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.
p.m. Frac Packs: Mladen Ruzic, Baker Oil Tools
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
trough effective removal of NWD. Almost all frac pack treatments
have been performed in cased holes utilizing crossover tools, sand
control screens and viscous cross-linked polymer based gels. Numerous
modifications of this well established standard have been tried,
including open-hole frac packs, applications of non-polymer fluids
as well as “screenless” treatments. This presentation
will focus on cased hole Frac Pack approach, where two well established
techniques: Hydraulic Fracturing and Gravel Packing are used simultaneously
in a way where key benefits of each are recognized and correctly
p.m. Sand Control Technology for Open Hole Horizontal Wells:
Steve Mathis, Baker Oil Tools
of the presentation will center on Sand Control Options. Included
are standalone screen completions, which must address annular flow
challenges. Combining packers with standalone screen will be discussed
at length, leading into expandable sand screens and horizontal gravel
packing advantages. Recent developments and case study information
lay the groundwork for the discussion.
