Who Should Attend?
All petroleum professionals involved in drilling and completion of wells, especially drilling, reservoir, completion, and production engineers and development geologists.


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.
