Director of Technical Services


Brian Oligschlaeger, 10 years working with all kinds of downhole oilfield equipment. This includes all of D&L’s equipment, with an emphasis on horizontal completions.

What is your specialty at D&L? 

I have spent a great deal of time working on horizontal open hole completions.  D&L prides itself on developing equipment to meet every particular customer’s needs. We strive to use a customer’s completions knowledge and build upon that to develop new innovative equipment.

What makes D&L’s products superior?

Attention to details in design and manufacturing. D&L is constantly taking on design challenges so the engineering staff stays sharp when it comes to what works well and what does not. This makes for an atmosphere of attention to details.
