Patents
Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names.
Use TI= to search in the title, AB= for the abstract, CL= for the claims, or TAC= for all three. For example, TI=(safety belt).
Search by Cooperative Patent Classifications (CPCs): These are commonly used to represent ideas in place of keywords, and can also be entered in a search term box. If you're searching forseat belts, you could also search for B60R22/00 to retrieve documents that mention safety belts or body harnesses. CPC=B60R22 will match documents with exactly this CPC, CPC=B60R22/low matches documents with this CPC or a child classification of this CPC.
Learn MoreKeywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.
Learn MoreChemistry searches match terms (trade names, IUPAC names, etc. extracted from the entire document, and processed from .MOL files.)
Substructure (use SSS=) and similarity (use ~) searches are limited to one per search at the top-level AND condition. Exact searches can be used multiple times throughout the search query.
Searching by SMILES or InChi key requires no special syntax. To search by SMARTS, use SMARTS=.
To search for multiple molecules, select "Batch" in the "Type" menu. Enter multiple molecules separated by whitespace or by comma.

locating a casing string within a wellbore, the casing string having at least one sensor attached thereto;
drilling into the formation using a tubular body;
measuring at least one formation parameter using the at least one sensor while drilling into the formation; and geosteering the tubular body using the measurements obtained while drilling.
locating a casing string within a wellbore, the casing string having at least one optical sensor attached thereto;
drilling into the formation using a tubular body having an earth removal member operatively attached to its lower end; and performing acoustic monitoring while drilling into the formation.
providing a casing string having at least one optical sensor attached thereto;
locating the casing string within a wellbore; and measuring one or more wellbore or formation parameters with the at least one optical sensor while drilling.
lowering the casing string into the wellbore; and setting the casing string within the wellbore with a bonding material.
locating a casing string having one or more optical sensors attached thereto within a wellbore;
measuring one or more parameters of the fluid flowing through the casing string with the one or more optical sensors; and using the one or more parameters to determine the flow rate of the fluid or one or more volumetric fractions of the fluid.
introducing a tubular body having an earth removal member operatively attached to its lower end into the casing string; and measuring one or more fluid parameters using the one or more optical sensors while drilling with the tubular body.
a casing string permanently located within a wellbore;
one or more optical sensors attached to the casing string for measuring parameters of a fluid flowing through the casing string; and control circuitry and signal processing adapted to determine a composition of the fluid or flow rate of the fluid based on one or more signals received from the one or more optical sensors.
