A method of enhancing carbonate precipitation in a downhole environment comprises introducing into the downhole environment a treatment composition comprising: a carbonate producing agent comprising a microbe, an enzyme, or a combination comprising at least one of the foregoing, and a substrate comprising N-oxyurea, semicarbazide, N,N-dioxyurea, or a combination comprising at least one of the foregoing. An organic feedstock and a geobacter can also be used to treating a wellbore or a subterranean formation. Encapsulated carbonate producing agent such as encapsulated bacterial spores are used to form self-healing cemented structure in a downhole environment.

Biologically mediated precipitation of carbonates for use in oilfield applications

A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising a carbonate producing agent, urea, and a cation source; allowing a carbonate precipitate to form, the carbonate precipitate comprising a cation from the cation source and having a water solubility of less than about 0.1 g/100 mL at 25&#xb0; C. and atmospheric pressure; and reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.

Methods of controlling fines migration in a well

A method of cementing a wellbore penetrating a subterranean formation comprises injecting into the wellbore a settable slurry comprising: an aqueous carrier; an aggregate; urea; a calcium source; and a calcium carbonate producing agent comprising a microbe, an enzyme, or a combination comprising at least one of the foregoing; and allowing the slurry to set.

Compositions and methods for cementing a wellbore using microbes or enzymes

A method of delivering a microbe or enzyme to a selected location comprises conveying a coated aggregate to a selected location; wherein the coated aggregate comprises an aggregate and a coating disposed on the aggregate; the coating comprising a polymer matrix and a calcium carbonate producing agent comprising a microbe, an enzyme, or a combination comprising at least one of the foregoing.

A motorcycle dolly is provided which includes a carriage for conveying the motorcycle parallel to a first plane and a prop mounted on the carriage for supporting the motorcycle in symmetrical orientation with respect to a second plane perpendicular to the first plane. In normal use, the first plane will be horizontal and the second plane vertical. The carriage consists of a chassis mounted on a plurality of casters. The casters have 360&deg; turn capability and a locking mechanism for preventing rotation of their wheels. A ramp slopes downwardly and away from the rear end of the channel to facilitate driving the motorcycle onto the web of the channel. The prop consists of a channel fixed to the carriage with the web of the channel perpendicular to the first and second planes and the flanges of the channel aligned to receive the front wheel of the motorcycle therebetween. At least one pair of resiliently flexible elongated plates is fixed to the inside walls of each of the flanges proximate one end of the plates. At least one pair of flexing mechanisms is mounted on each of the flanges and engageable with one of the plates. Each flexing mechanism cooperates with its associated flange to vary the distance between the plates and lock the motorcycle in the vertical condition.
