LCM Recovery System

Technical Overview

Environmental Dri l l ing Solutions (EDS) has developed a proprietary LCM Recovery System which can be

used to recover and reuse lost circulation material . This reduces operators' costs of LCM, and maintains

LCM concentrations in the dri l l ing flu id to help improve wel lbore integrity.

The EDS LCM Recovery System consists of either a single auger tank with 100 bbl capacity (85 bbl working

capacity) , or a dual auger tank with 195 bbl capacity (180 bbl working capacity) .

LCM Recovery System Overview

The auger tank accepts the ful l flow from the wel l bore by bypassing the rig mounted shale shakers. By-

passing the rig shakers to the EDS auger tank al lowing al l LCM to remain in the active mud system.

Dri l l ing flu id flows back into the active rig pits through the equal izer l ine from the auger tank back to the

active system.

Zero agitation in the tank al lows the cuttings removed from the wel lbore to fal l out of the mud system and

to the bottom of the tank.

Cuttings that fal l to the bottom of the tank are then removed with the augers.

Cuttings can be conveyed to the reserve pit or trucks to be hauled from location.

To conserve valuable dri l l ing flu id , the cuttings can instead be conveyed to an EDS vertical dryer or EDS

drying shakers.

Effluent from the vertical dryer or drying shakers can be centrifuged and returned to the active mud

system.

How It Works

By uti l izing the EDS LCM Recovery System we

minimize the need to pump and dump to

control dri l l ing flu id weight and sol ids content

Since cuttings are continuously being removed by

the auger tank there is no need to jet active rig

pits to remove cuttings due to bypassing the rigs

shale shakers

By minimizing the amount of dri l l ing flu id that is

dumped to jet pits, the amount of fresh dri l l ing

flu id that is bui l t on location is minimized

Retaining the LCM in the active dri l l ing flu id

system minimizes the amount of new LCM that

needs to be mixed to keep the needed

concentration

Reduces overal l waste generated at the wel l site

Reduces costs and l iabi l ity associated with haul -

off trucking for off-site disposal

Reduces the size of reserve pits needed to hold

dumped volume and cuttings

Reduces the amount of time and money spent on

cleaning cuttings from active mud pits
