Downhole fluid analysis while drilling

Hydrocarbon fluid composition while drilling

Gas/oil ratio while drilling

Field development planning while drilling

Fluid mapping while drilling provides representative fluid sampling, in situ downhole fluid analysis, and high-quality formation pressure measurements—so you can make better steering decisions and optimize reservoir productivity.

“Fluid sampling while drilling will soon give us the possibility to perform a complete formation evaluation in a single run while reducing acquisition time and rig cost.”

Sampling While Drilling: An Emerging Technology

Even though it is the early days of the realization of sampling while-drilling (SWD) as a service, a picture of what might be achievable in practice is beginning to emerge.

Sampling technologies withstand and operate under rigorous drilling conditions

Characterization of Sampling While Drilling Operations

The while-drilling environment poses several potential challenges to acquiring representative formation-fluid samples; in particular, sampling times are expected to be restricted (perhaps severely) and dynamic filtration conditions are expected to predominate.
