Coated films with good low temperature sealing properties and hot tack

Abstract: Novel coated films are disclosed wherein a base polymer film, e.g., oriented isotactic polypropylene, is coated with a composition comprising a copolymer of about 65 to 95 wt.% ethylene and about 5 to 35.% of acrylic or methacrylic acid (an 'ethylene copolymer') based on the weight of the polymer in which about 2 to 80 % of the carboxylate groups are neutralized with metal ions from Group Ia, IIa or IIb of the Periodic Table, preferably sodium ions. Preferably the coating also contains microcrystalline wax and fumed silica. The coated films exhibit good low temperature sealing properties accompanied by satisfactory hot tack and resistance of the seals to immersion in water.

Method for suspending wells

Abstract: A process for killing and suspending mixtures of hydrocarbonaceous fluid production, particularly oil, in a formation containing same which minimizes formation damage. First, a "Spacer volume" of liquid containing a chemical blowing agent is directed into the formation's productive interval. Said blowing agent decomposes in the formation and generates gas sufficient to force hydrocarbonaceous fluids away from a wellbore in said formation. Afterwards, a solidifiable pumpable gel mixture is placed via a wellbore into the formation's productive interval and also within said wellbore. Said mixture solidifies in the formation and forms a gel plug within the wellbore. Thereafter, a light weight cement is placed over said gel plug effectively "killing" and suspending the production of hydrocarbonaceous fluids. The gel mixture comprises (1) water; (2) a cross linkable polymer having at least one functional group selected from a member of the group consisting of an amide, an amine, a hydroxyl, or a thiol group; and (3) a partially methylated aminoplast resin which cross links with said polymer.

Selective production of para-xylene

Abstract: Process for the selective production of para-xylene by methylation of toluene in the presence of a catalyst comprising a crystalline aluminosilicate zeolite, said zeolite having a silica to alumina ratio of at least about 12 and a constraint index, as hereinafter defined, within the approximate range of 1 to 12, which catalyst has undergone prior modification by treatment with an ammonium hydrogen phosphate to deposit at least about 0.5 weight percent of phosphorus thereon.

Oil recovery process for use in fractured reservoirs

Abstract: A process for recovering oil from fractured formations is provided which involves altering the wettability of the formation, particularly at the interface of the fracture and rock matrix. The process of the present invention improves the ability of injected fluids flowing in the fracture to enter the rock matrix to displace oil. When employed in conjunction with a water-wet fractured oil-bearing formation, the process comprises the steps of: injecting a wettability agent capable of transforming the water-wet fractured formation from water-wet to oil-wet; contacting the oil-wet fractured formation with the wettability agent so injected at a fracture/matrix interface; injecting an oil miscible solvent; and recovering oil. A process for use with an oil-wet fractured oil-bearing formation is also provided.

Multifunctional lubricant additives and compositions thereof

Abstract: Metal salts of partially borated, partially phosphosulfurized polyols and hydroxyl-containing esters are effective multifunctional friction reducing, antioxidant and copper strip passivating additives when used in lubricating media.
