In Jefferson County, Erin Mulligan sits at her computer in the Colorado county's regional crime lab. It's not quite "CSI: Colorado" but it can sometimes feel that way to her. As a forensic scientist, ...

The thin thickness of the sand body and the low oil recovery in the marginal reservoirs of the X area in D oilfield pose significant challenges. Using ultra-short radius horizontal wells is effective ...

I was blown away by Gary Keller’s book The One Thing when I read it on the top floor of a Bangkok apartment complex. I'd been going through plenty of stress back then. I had taken on too many projects ...
