Dan W. Pratt is Vice President of Engineering and Technology for Owen Oil Tools LP, a division of Core Laboratories.  Dan has 38 years experience working in the areas of design and manufacture of oilfield explosives products, more specifically with oilfield perforators or shaped charges.  Dan holds undergraduate and graduate degrees in Chemistry, Engineering and Physics from the University of Texas at Arlington.  Dan is an inventor on numerous U.S and foreign patents related to the design of shaped charges, shaped charge liners, materials used in their manufacture and propellant stimulation.


Dan is a member of numerous professional organizations including SPE, AIME and AIChE.  He is an active member of the Society of Explosives Engineers, the Institute of Explosives Engineers (UK), and is a Founding Lifetime Member of the International Ballistics Society.  Dan is Owen’s principal member on the API (American Petroleum Institute) SC19 Subcommittee on Completion Equipment and spent over 25 years on the 19B Task Group on Perforating.

Full Description

 

The desired result of perforating has always been to establish effective communication between the wellbore and the producing formation.  In the past, the design focus for perforators has been on either increasing the depth of penetration or enlarging the hole size.  The need for effective perforating schemes in horizontal unconventional wells has driven the development of new, enhanced perforating systems geared specifically toward hole-size consistency. 

Operators commonly specify a desired hole size from their service provider to complement their treatment design.  While the average hole size might meet that requirement, the deviation from maximum to minimum hole size in a particular orientation can be drastic and could lead to increased perforation friction, increased tortuosity, and reduced cluster efficiency.  A new classification of perforating charges referred to as consistent hole-size perforators will be discussed, along with the methodology for collecting and publishing the pertinent data.
