The EZ Hull Bulk LCM System and EZ Hull Process benefit both Operators and Drilling Contractors by:

Reducing the Cost of Lost Circulation Material (LCM)
by supplying bulk materials, the EZ Hull Process eliminates material handling, bagging costs and transportation costs typically associated with sack material. With sack products, LCM is purchased in bulk form, transported to a bagging facility, unloaded, bagged, palletized, reloaded on to a truck for transport to the rig site, off loaded and then moved by hand to the mud pit for introduction into the mud system. The EZ Hull Process eliminates this excess material handling cost as there is no bagging cost which expedites the introduction of the LCM into the mud system. What does this mean to you? Substantial reduction of your mud dollar expenditure, improved productivity at the rig, reduction of waste, and a safer environment for the rig crew.

Reducing labor costs
only one rig hand is required to efficiently operate the EZ Hull equipment instead of the usual 2-3 men required to haul, cut and introduce sack material into the pit.

Reducing Employee Turnover Rate
due to employee dissatisfaction related to handling bulky, heavy material in adverse weather conditions

Reducing Waste
and related disposal costs incurred as a result of having to remove from location the bags used to package the various forms and types of LCM

Improving the Safety of the Drilling Rig Environment
by decreasing back strains and cuts or abrasions which result from physically carrying 100# bags of LCM from the mud house or trailer, up the steps to the mud pit, opening the bag and introducing the material to the mud systems by lifting the LCM above the waist and shaking it into the mud system.

Improving Rig Crew Productivity
by utilizing only one rig hand to introduce or maintain a predetermined concentration of LCM to the system as opposed to 2-3 rig hands in a sack operation. By utilizing the E-Z Hull Process, additional personnel can perform rig maintenance, make quicker connection, or focus on other rig requirements. This improves the productivity of the drilling rig, thereby reducing the operators overall drilling expenditure. These types of savings are computed in the attached spread sheet entitled "Connection Time Analysis" which was prepared by an outside consulting firm at the request of an operator who wanted to compute time and productivity saving as a result of implementation of the EZ Hull Process.

By using the EZ Hull Process, rig crews can keep more personnel on the rig floor to aid in faster connection time.   Customer feedback indicates saving an average of 5 minutes in connection time when using EZ Hull. As evidenced by the analysis above a reduction in connection time of 5 minutes would save the Operator $31,989.

In addition to connection time savings by keeping rig hands on the floor, the estimated savings to perform general rig maintenance and the reduction of sack material disposal is approximately $10,000 per well.

Rig time to 'Hull Up' in the event of lost circulation with EZ Hull is reduced from an estimated 2 full system circulations to only one complete mud system circulation. At 8000' this would result in rig time savings of approximately of 4 hours, or $4000, using the rig rate shown above.
