Abstract: The invention provides a method for the combinatorial mutagenesis of a parental nucleic acid. The method consists of: (a) extending by enzymatic polymerization a first mutagenic primer annealed to a parental nucleic acid to produce an extension product; (b) treating said extension product with a cleaving reagent selective for a nucleotide sequence present in the parental nucleic acid but absent in the first product; (c) extending by enzymatic polymerization a first PAP annealed to a noncontiguous region of said mutagenic primer to produce a first product having a first mutagenized portion comprising one or more altered nucleotides, the first PAP containing a unique sequence tag associating mutations within the first mutagenic primer with the first PAP; (d) annealing the first product to the parental nucleic acid, and (e) extending by enzymatic polymerization the annealed first product to produce a first modified parental nucleic acid containing a first mutagenized portion. The first product can additionally be amplified. The method also provides the additional step: (f) amplifying the first modified parental nucleic acid containing a first mutagenized portion by polymerase extension of an annealed first SAP to the unique sequence tag contained in the first PAP  and an annealed second PAP to the first modified parental nucleic acid, the first and second PAPs corresponding to flanking regions of the parental nucleic acid. The method additionally provides the steps of: (g) repeating steps (a) through (c) one or more times with a second mutagenic primer and a third PAP to noncontiguous regions of the parental nucleic acid to a second product having a second mutagenized portion, the third PAP containing a unique sequence tag associating mutations within the second mutagenic primer with the second PAP, and (h) repeating steps (d) through (e) or steps (d) through (f) one or more times by annealing the second product produced in step (g) to the parental nucleic acid or the first modified parental nucleic acid produced in step (e) or (f) to generate a second modified parental nucleic acid containing a first mutagenized portion and at least one second mutagenized portion. Steps (g) and (h) can be repeated one or more times with tertiary mutagenic primers.

Abstract: Non-contacting means of measuring the material velocities of harmonic acoustic telemetry waves travelling along the wall of drillpipe, production tubing or coiled tubing are disclosed. Also disclosed are contacting means, enabling measurement of accelerations or material velocities associated with acoustic telemetry waves travelling along the wall of the tubing, utilizing as a detector either a wireless accelerometer system or an optical means, or both; these may also be applied to mud pulse telemetry, wherein the telemetry waves are carried via the drilling fluid, causing strain in the pipe wall that in turn causes wall deformation that can be directly or indirectly assessed by optical means. The present invention enables detection of telemetry wave detection in space- constrained situations. The invention also teaches a substantially contactless method of determining the time-based changes of the propagating telemetry waves. A final benefit of the present invention is that it demonstrates a particularly simple contacting means of directly measuring wall movements in live coiled tubing drilling environments.

Abstract: A method for separation of heterogeneous products included in household waste (HW) comprises separating the products in a fractionation vessel containing a liquid. The waste includes components, of which at least some are capable of floating in the liquid.

Inventor: HARDING DARIN MERLE
IPC: E21B21/06
Filed: 2002-05-09
Abstract: A method and apparatus for recycling drilling fluids used in the drilling of wells is provided. The apparatus can comprise a tank having a plurality of compartments. Drilling fluid containing solids pumped into a receiving compartment of the tank is directed towards a flow-reversing barrier to cause heavier solids to settle to the bottom of the tank. Fluid filling the receiving compartment flows downstream into an adjacent compartment by passing through a flow-restricting baffle to cause more solids to settle. As fluid flows from compartment to compartment, it passes through successive flow-restricting baffles to cause further solids to settle. Once fluid reaches a collecting compartment, the fluid can be used again in drilling operations. A  conveyor extending along the bottom of the tank moves settled solids out through an outlet in the collecting compartment. The settled solids can then be passed through a centrifuge to recover residual fluids.
