Abstract: A method and apparatus for collecting waste liquid at a wellhead from an above ground source conduit when wireline apparatus and/or associated tools are withdrawn from a well includes providing a manually portable waste liquid containment assembly having a valved conduit subassembly that is connected in fluid-tight relation to the source conduit, and admitting waste liquid into the containment assembly at the drilling site. The waste liquid containment assembly includes a water and flame resistant cellulosic container fitted with a plurality of flexible oil and water impermeable polymer bags nested one inside of the other, the innermost polymer bag containing an oil-absorbent natural product. The valved conduit subassembly has components to safely control the waste liquid during the filling of the polymer bags, including a control valve, a check valve and a pressure relief valve. Conduit couplings join the conduits, which can include flexible sections, in fluid-tight mating relation.

Abstract: A wastewater container, or fluid capture tank, for capturing fluid from a flare is provided, along with methods for making and using the fluid capture tank. The fluid capture tank includes an open top tank to hold fluid for disposal, and a flare chute mounted to one end of the open top tank. The flare chute includes three panels, including a bottom panel mounted to a left wall panel and a right wall panel, wherein the three panels direct fluid from a line into the open top tank. A refractory lining is disposed on an inner surface of at least one of the three panels facing the line, wherein the refractory lining protects the inner surface from heat as hydrocarbons in the fluid are burned.
