With standard equipment, most errors in ROP are related to the operation of the geolograph. When a connection is made, the driller should disengage the geolograph recorder before picking up a new joint of pipe. Unless this operation is performed properly, the rate of penetration just prior to or after a connection can be questionable. In addition, high winds can whip the geolograph recording cable, causing extra footage to be recorded. It is not unknown for the drilling hands to “gig” or pull on the recording cable, causing a similar apparent increase in ROP. The ideal reorder point is one where the ordered inventory will arrive before you dip below a comfortable level, but not so early that storing and tracking it becomes a problem.
Lead time is when you place a purchase order with your supplier or manufacturer for a product and when you receive the product.

When the safety stock number is added to the average demand, you have your reorder point. Suppose your manufacturing company consumes 100 units of raw materials per day to produce a finished good.

Keeping optimal stock levels in order to avoid stockouts is an integral task of inventory management. One of the most fundamental ways in which to ensure this is setting and maintaining the right reorder points.
