    Abstract: The invention relates to a racquet that is provided for use in games in which it is used for striking a ball that has a tail, the tail being in the form of a plurality of elongate streamer elements that are anchored to the ball. Such a ball generally has a mass less than 30 g and thus requires the racquet to have a mass less than 200 g. In order to avoid tangling of the tail of the ball with the racquet after the ball has been struck with the racquet, the frame of the racquet is provided with anti-tangle formations that effectively space the exposed part of the strings of the racquet from the outer peripheral edge of the head part of the frame by between 20 and 30 mm.

    Abstract: The present invention relates to a corrosion inhibitor for use in the oil and gas exploration, recovery and processing industries. In particular, the invention relates to a quaternary ammonium compound suitable for use as such a corrosion inhibitor, to the manufacture of the quaternary ammonium compound, to compositions containing it, and to methods of using it. Quaternary ammonium compounds of the invention have the formula (I) in which R is C1-6 alkyl, C2-6 alkenyl, aryl, aralkyl; X, Y, and Z are each independently hydrogen, or R1CO—, provided that at least one of X, Y and Z is R1CO, where R1 is C5-23 alkyl or alkenyl containing 0, 1, 2 or 3 double bonds; D is C2-6 alkylene; E is C2-4 alkylene; p, q and r are each, independently, integers from 0 to 20, with the proviso that p+q+r is from 3 to 20; and A− is an anion.

    Abstract: Drilling, completing or workover of a well, particularly an oil and/or gas well, is carried out using a fluid which includes a continuous phase including an ester of the formula (I): (R2)p-Ph-(CH2)m—COO-(AO)n-R1 where R1, AO, n, m, Ph, R2 and p have defined meanings and particularly where the esters are alkyl or alkenyl benzoate esters. These esters are beneficial by having a range of viscosities, especially extending to low viscosities, and attractive toxicological and environmental profiles for use in drilling, completion and/or workover of wells.

    Abstract: A well drilling method comprises removing the drilling cuttings using an aqueous drilling fluid such as a foam including a foaming agent which includes at least one mono-(aliphatic hydrocarbyl) phosphate ester. More specifically, the drilling fluid takes the form of a potassium and/or alkanolamine and/or alkylalkanolamine salt, the foam also comprising a foam stabiliser.
