Two forward thinking mudlogging and geological service companies have announced an alliance to bring a fresh look to the business. The first is Diversified Well Logging, a leader in offshore deepwater and unconventional operations in the United States and Mexico. The second is Geowellex do Brasil, an 8-year old company and a leader in wellsite experience of …
FORMATION EVALUATION RETURNS TO THE SURFACE Realtime formation evaluation at the wellsite used to be carried out by geologists or mud loggers examining the drilled cuttings and formation gas collected from the mud stream and “lagged” to bit depth. This was mud logging or surface logging or data logging. Over the years, technological advances and …
In a Rigzone article on June 10th, 2020, ConocoPhillips CEO Ryan Lance was quoted as saying “Shale is not broke; shale is not gone; shale will come back.” While the third statement seems to contradict the second, we all know what he means, and we all agree. Shale and other tight unconventional hydrocarbon plays are …
All wells experience problems while drilling. Problems that result in unexpected hazards that can affect the safety of workers, damage to equipment and facilities, cause environmental damage, and greatly increase cost. Offshore, and especially in deepwater environments, if you only practice reactive control, these hazards could potentially add huge direct and indirect costs to a …
This ‘blog’ is inspired by some excellent photography by John Wagner who captured the ‘title-image’ on one of our rigs in Oklahoma. When difficult times hit the upstream oil industry, something which seems to be increasingly frequent, it helps that companies such as Diversified Well Logging, LLC., (DWL) can rise to the occasion and deliver …

In response to a couple of posts about the ‘death’ of mud logging in hard times and the scant attention paid to cuttings and gas information by oil companies, I think we need to consider a few things. 1) In the dim and distant past mud logging was the only method of getting realtime geological data …
When a stereoscopic microscope, tweezers, sample probe, some chemicals, and an ultraviolet lightbox were the ‘state-of-the-art’ in cuttings evaluation equipment, mud-loggers and geologists did a very good job in identifying drilled formations all things considered. Similarly, when coach-and-horses and sailing ships were the ‘state-of-the-art’ in transportation, they also did a very good job transporting people …
Since early days of the oil industry, gas liberated from the formation during drilling has been looked at as a means to predict what type of hydrocarbons are lurking in the reservoir. Various ratios and procedures have been tried and tested with various measures of success in reservoirs around the world. The major lesson learned …
