    Abstract: The time required for establishing a multilateral well is reduced by enlarging a section of a wellbore and running a multilateral tool (7) which includes a preassembled combination of casing sections that form dual casing strings extending from the primary casing. The multilateral tool (7) incorporates a carrier section (2), a lateral section (8), and a main section (5). The tool is run with the lateral section (8) releasably held in coaxial alignment within the carrier section (2), and with the main section (5) fixed to the lower end of the carrier section (2). Once in place, the lateral section (8) is released and diverted out of a preformed window (4) in the lower end of the carrier section (2) and runs generally parallel to the main casing section (5). A lateral junction is thus formed at the carrier section window (4) in which dual casing strings are connected to the primary casing. A second window, preformed in the upper end of lateral section (8) is aligned with the bore of the primary casing when the lateral casing section is fully extended out of the carrier section window (4), thus permitting recovery of a diverting device incorporated in the carrier casing section (2) through the second window. The dual strings are then individually drilled and completed with pressure integrity between the dual strings maintained by using straddle equipment across the lateral junction.

    Abstract: A process for desalting a crude oil comprises (1) injecting steam into the oil to form a steam-injected oil; (2) adding water to the steam-injected oil to form a mixture; (3) introducing the mixture to a desalter; (4) inducing the formation of aqueous phase and oil phase; and (5) separating the oil phase from the aqueous phase. Where there are two desalting stages for desalting crude oil, the process can be carried out in either the first stage or second stage, or both stages. The process can also be similarly employed in a multistage desalting process.

    Abstract: Sequential charging of initiator and monomers in a multistage solution polymerization process involving conjugated diene and monovinylaromatic monomers wherein the final charge is a mixture of these monomers results in the production of resinous polymodal linear block copolymers each with a terminal tapered block. A typical 5-stage charge sequence is as follows: Stage 1: (Si); Stage 2: (Si); Stage 3: (B); Stage 4: (Si); Stage 5: (S+B) wherein (Si) is monovinylaromatic monomer and initiator; (B) is conjugated diene monomer and (S+B) is monovinylaromatic monomer and conjugated diene monomer. At each stage, polymerization is allowed to continue until no free monomer is present. The trimodal block copolymer products comprise high, medium and low molecular weight species designated, respectively, as S1-S2-B1-S3-B2->S4; S2-B1-S3-B2->S4; and S3-B2->S4 wherein S1, S2 and S3 represent, respectively, polyvinylaromatic blocks resulting from polymerization of the first, second and third charges of monovinylaromatic monomer (stages 1,2 and 4); B1 represents a polydiene block resulting from polymerization of the first charge of conjugated diene monomer (stage 3); and B2->S4 represents a terminal tapered copolymer block resulting from polymerization of the conjugated diene and monovinylaromatic monomers (stage 5). The subject copolymers can be fabricated into sheets and molded objects possessing little color, a high degree of transparency and excellent impact resistance. These fabricated products do not craze on being impacted.
