It seems that this post contains plag. Unfortunately, utopian and steemstem were not quick enough to remove their votes. For proof see below.

I think it is fair that from now on you will receive downvotes equivalent to the amount of upvotes given by steemstem and utopian.

Source: The associated cost of importing such materials for drilling opera-tions is estimated to amount into millions of dollars per annum andthis is damaging to the economy. Furthermore, as the search for oil and gas reserves shifts from onshore areas to offshore and deep offshoreregions, likewise is the associated cost of the overall drilling operation.The cost of drilling operation is also influenced by the performance ofthe drillingfluid. This in turn makes the design, formulation and main-tenance of drillingfluids important

Post:The associated cost of importing such materials like bentonite clay for drilling operations is amounts to millions of dollars per year and this is damaging and detrimental to the Nigeria economy. Furthermore, as the exploitation for oil and gas reserves expands from onshore regions to the offshore and deep offshore areas, the associated financial cost for an effective and efficient drilling operation tends to increase. It should be noted that the cost of drilling operation is highly influenced by the performance of the drilling fluid and this in turn makes the design, formulation and maintenance of drilling fluids important.
