  • Publication number: 20130178400
    Abstract: Emulsified acids have been used to increase production rates of oil and gas in carbonate reservoirs through acid fracturing and matrix acidizing operations. An emulsifier is used to emulsify the aqueous acid with an oil, usually diesel. Very small particles, such as colloidal clay particles and/or nanoparticles increase the stability of the emulsified acids over an elevated temperature range.

  • Patent number: 8282962
    Abstract: One aspect of the present invention relates to a readily water-dispersible particulate composition comprising by weight of dry matter at least 10% of xanthan gum and not more than 60% of starch, said composition being characterized in that the xanthan gum present in the composition can be dispersed completely within 2 minutes in distilled water of 25° C. at a concentration of 0.7% based on the dry weight of xanthan. The particulate xanthan gum compositions of the present invention exhibit unique viscosity enhancing properties that are dependent on the electrolyte levels of the aqueous environment in which they are applied. The favorable properties of the xanthan compositions according to the invention can be realized without resorting to chemical modification of the xanthan gum. The xanthan compositions according to the present invention can be applied advantageously in e.g. food products and oil drilling fluids.

  • Publication number: 20120072337
    Abstract: When a buyer's debt to a seller cannot be paid using an account issued to the buyer by an issuer within a payment processing system, then either or both the seller and the buyer are solicited to conduct future transactions payable on the account. If the debt can be paid using the account, then a sub-account is created unique to the seller and buyer. Transactions between the buyer and seller can be processed using the sub-account including the option of aggregating the debts prior to the processing. The credit limit of the sub-account can be set to match the amount of the aggregated debts.

  • Patent number: 7975520
    Abstract: A tab is used to open beer/beverage can ends and food can ends. The tab has one or more arcuate strips that are provided on a surface of the tab proximate to a peripheral surface of the tab where the one or more arcuate strips have been formed further into a preselected portion of curled or hemmed portions of the tab. Tooling for the manufacture of the tab is also provided. A method for manufacturing the tab is additionally provided as well.

  • Publication number: 20110147382
    Abstract: A tab is provided, which includes a body having first and second opposing ends, a nose portion disposed at or about the first end of the body, a lift portion disposed at or about the second end of the body of the tab, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a generally planar portion, a rivet hole having a perimeter, and an upturned portion extending upwardly from the generally planar portion about the perimeter of the rivet hole. The upturned portion reinforces the rivet hole and has an arcuate cross section profile. An integral rivet extends through the rivet hole and is staked to affix the tab to a can end. The upturned portion is devoid of any corners or edges both before and after the integral rivet is staked.

  • Publication number: 20110055079
    Abstract: A web service facilitates real time payment of suppliers' invoices with accounts issued by issuers to account holders. A payment request received by the web service from a client, identifying a credit limit for one commercial account in a pool thereof, is sent from the web service to the issuer to determine availability of the account and the credit limit for an account holder. If the issuer's response to the request confirms availability, payment instructions to the issuer are sent from the web service to pay the supplier's invoice. Alternatively, the request can be to determine availability of a single-use-account (SUA) and an adjustment to the account holder's credit limit from the issuer in order to make a future single payment on the SUA to the supplier for a purchase corresponding to a future invoice from the supplier who has not yet provided goods and/or services pertaining to the invoice.

  • Publication number: 20110005752
    Abstract: Water production produced from a subterranean formation is inhibited or controlled by consolidated water sensitive porous medium (WSPM) packed within the flow path of the wellbore device container. The WSPM includes solid particles having a water hydrolyzable polymer at least partially coating the particles. The WSPM is packed under pressure within the flow path of the wellbore device container to consolidate it. The WSPM increases resistance to flow as water content increases in the fluid flowing through the flow path and decreases resistance to flow as water content decreases in the fluid flowing through the flow path.

  • Publication number: 20090095752
    Abstract: A tab is provided to facilitate opening of a can end. The tab has a nose portion located at a first end of the tab and a lift portion located at a second end of the tab opposite the nose portion. A rivet receiving portion is located proximate to the nose portion, and includes a rivet hole. A flange extends rearwardly from the lift portion of the tab to define a gap. The gap provides increased space between the underside of the flange and the exterior of the container end, thereby facilitating opening of the container end.
