Gumbo boxes are the first step in effective solids control when large, sticky, hydrated clays (gumbo) and other troublesome solids are encountered during drilling. Gumbo boxes use a motorized chain conveyor to remove problematic solids before they reach the shale shakers.

2018年5月8日 · The larger size lines are used on rigs having greater circulating rates and/or drilling soft reactive shales called gumbos. These gumbos drill fast, absorb water, swell, and emerge from the bell nipple in large clay-like masses. This gumbo can plug even a properly sloped flowline causing the mud to spill over the top of the bell nipple or trough.

2015年10月26日 · Drilling fluid easily passes through the relatively wide spacing in the rods, and the sticky gumbo mass slides down to disposal (Figure 6.1). Several manufacturers have now built gumbo removal devices for rig installation.

Gumbo: A Sticky Problem in Shale Formations. In the world of oil and gas exploration, "gumbo" isn't a dish, but a geological headache. This term, used by geologists and drilling engineers, describes a specific type of sticky, reactive shale formation that presents significant challenges during drilling and well completion.

Location of a gumbo box is evalu-ated for usefulness, ease of access and mechanical opera-tion. Other elements of the solids con-trol system inspection include: • Age and condition of the shak-ers; • Direction of motor rotation; • Belt tension; • Conditions of the jacks, cush-ions and seals; • Desander, desilter and mud

Drilling fluid design is the cure for problems caused by gumbo shale. Five remedies for controlling gumbo problems have been used: removing shale cuttings from mud. The drilling fluid components used for each of the five control measures are evaluated in terms of effectiveness in the different types of gumbo shale.

2003年6月30日 · During a recent GoM effort to drill 3,200 ft of 17-in. hole, use of Hydro-Guard yielded a low 7.5 methylene blue test (MBT), compared with 25-30 MBT for a typical partially hydrolyzed polyacrylamide polymer fluid under equivalent drilling conditions, the company said.
