The following are cost spreadsheets from area well data.
To the best of our knowledge, it is a true representation of the costs
involved. By itself though, it is a partial analysis. And while it has
great potential, it can potentially mislead the decision making process.
The Bulk Handling system must be cost justified, but not limited by traditional
criteria used by drilling & operational engineers. By placing the complete
analysis and decision making in terms of spreadsheet analysis of those
terms which are not easily quantifiable and are familiar, the engineer
may become biased towards the exact quantifiable magnitudes. It is, to
a large extent, those items which are not easily quantifiable that weighs
the decision of using bulk handling systems with drilling fluids. We are
confronted with a requirement to change the nature of the traditional operation
decision making process to include fields of knowledge wider than those
normally employed. Other expertise needs to be included to provide estimates
of more difficult costing functions.
|
|
Several of these Costing Functions are :
|
|
-
Safety : What are the savings or productivity
increases due to fewer LTA's in terms of insurance premiums or morale ?
|
|
-
Environmental : What are the savings or incresed
return associated with a more motivated crew working in a dust free and
clean work area ?
|
|
-
Health : What is the reduction in man days
lost due to dust type, or chemical burn related injuries ?
|
|
-
Labor : How do we quantify the reduction in
manpower, not just in cutting sacks, cleaning debris, or adding chemicals,
but rather in work enhancement of a better working environment ?
|
|
-
Technical : How much chemical is saved by having
all chemicals added consistantly by a computer avoiding fluctuating properties.

Net Savings Per Well
|
$ 18472.00 |
This savings excludes intangible dollars
sush as injuries, liabilities, environmental,
etc.
Bulk Systems eliminate, or greatly reduce these
costs as well.
Frequently all that is assessed is the direct cost, the more
easily identified costs. The spreadsheet itself becomes the sole decision
making tool. The use of Bulk handling systems is easily justified when
a broader view is taken. A new method of analysis is used , in which the
Operations Engineer ( and the spreadsheet ) is but one of several inputs
to the decision process. Other disciplines are included and involved, they
are : Logistics, Safety, Quality Assurance, Chemistry, Medical (
or Health ), Environmental, Risk Management, and finally Top Management. |
