Abstract: Directional drilling is an extremely important area of technology for the extraction of oil and gas from earthen formations. The technology of the present application relates to improved non-stabilizer guidance positioning members for directional drilling assemblies and for drill strings. It also relates to an improved method for analyzing the fit and engagement of a directional drilling assembly in curved and straight wellbores in order to produce improved guidance positioning members. It also relates to a method of designing guidance positioning members for directional drilling. It also relates to drilling directional wellbores using the guidance positioning members of the present technology.

Abstract: The invention includes a method of lubricants supply chain management including: storing in a web-accessible database a catalog of lubricants and prices-per-unit for same which prices-per-unit optionally decrease based on certain pre-determined cumulative volume purchases; upon receiving at a web server a request from a web-browser client, querying the database and serving the results of the query to the requesting web-browser client for display; serving an order form to the web-browser client which is configured to contain fields for order quantity and type for lubricants, delivery type preferences and delivery address entered in the web-browser client, and determining and displaying on the web-browser client a delivery price quote; receiving an order from the web-browser client for a specific type and quantity of lubricants and having a specific delivery type selected; electronically transmitting over a network the order to an order fulfillment agent; where the order fulfillment agent electronically transmi
