 On the other hand, wellsite palynology requires complex additional equipment to deal with the sample processing side of the operation. Samples required for palynological analysis need to be processed by a variety of different chemicals – mainly strong acids and alkali solutions. It is the handling and disposal of these corrosive and toxic chemicals during sample processing (normally these occur in purpose-built laboratories) that provide challenges for wellsite operations. Such equipment (fume cupboards, vapour scrubbers, neutralising and holding tanks etc.) has been effectively miniaturised and built into offshore-certificated, pressurised units. These can be shipped to the rig and hooked into rig electrical and water supplies. They are usually manned by a laboratory technician as processing is an intensive process, and which the palynological scientist (palynologist) would not have time to undertake themselves as well as analysing the processed samples.

+//A nannopaleontologist works in a purpose-built biostratigraphic unit on a well west of Shetland. The presence of the fume cupboard shows that it is set-up for palynological processing. These units are normally only used at rigsite for longer-term, multiwell contracts. For "one-off" jobs not involving palynology, biostratigraphers usually work in the Mudlogging Unit or in offices inside the accommodation area. The polystyrene cups contain cuttings samples for the biostratigrapher, caught and provided by the Mud Loggers.//
 Some companies have experimented with “acid-free” palynological preparation techniques with varying degrees of success but even this technique requires equipment which cannot be hand-carried to the wellsite and also requires a degree of connection to rig services.
