The present invention generally relates to improved compositions comprising stabilized colloidal or colloidal-like phases (e. g. , emulsions, aphrons) and methods of using those compositions. The compositions generally comprise an aqueous continuous phase, one or more viscosifiers, one or more surfactants, aphrons and one or more Aphron Stabilizers. The compositions of the present invention possess aphrons with significantly increased half-life and enhanced ability to seal permeable formations, and are capable of being used in high pressure applications.

A process to substantially reduce fluid loss in which an appropriate amount of a non-flowing gel of sufficient strength is emplaced to substantially eliminate or reduce loss of the drilling fluid. The gel composition of the process includes: (1) a non-cellulose containing copolymer having vinyl phosphonate co-monomer units which may be incorporated into the polymer by copolymerization with the other co-monomer(s) comprising the polymer or by grafting upon an already existing polymer or co-polymer, (2) a crosslinking agent active upon the phosphonate groups, (3) a crosslinking initiator comprising a Bronsted Lowry base or Lewis base and (4) an aqueous solvent.

507222, 507122, 526287

Compositions for increasing the thermal and pressure stability of well fluids viscosified using viscoelastic surfactants, the compositions including an effective amount of an oligomeric or polymeric compound that has a thermally stable backbone structure and at least one pendent viscoelastic surfactant functional group. Preferred compositions for increasing the stability of well fluids viscosified using monomeric viscoelastic surfactants include an effective amount of an oligomeric or polymeric compound that has a thermally stable backbone structure and a multiplicity of pendent viscoelastic surfactant functional groups attached to said backbone structure through relatively long hydrocarbon chains, 1 to 18 carbons in length.

A process for generating and subsequently breaking a filter cake, including dissolving a non-reactive gas in a wellbore fluid to form an energized fluid; pumping the energized fluid into a formation at a downhole pressure, wherein the pumping is at overbalanced conditions; producing a filter cake; and decreasing the down hole pressure to below a cut point of the dissolved gas in the energized fluid to form a vapor phase, wherein the vapor phase compromises the integrity of the filter cake is disclosed.

A method for planning a wellbore, the method including defining drilling data for drilling a segment of a planned wellbore and identifying a risk zone in the segment. Additionally, the method including determining an expected fluid loss for the risk zone and selecting a solution to reduce fluid loss in the risk zone. Furthermore, a method for treating drilling fluid loss at a drilling location, the method including calculating a drilling fluid loss rate at the drilling location, classifying the drilling fluid loss based on the drilling fluid loss rate, and selecting a solution based at least in part on the classifying.

A biodegradable wellbore fluid with an oleaginous phase including a linear paraffin having 11-18 carbon atoms, a non-oleaginous phase, an emulsifying agent and optionally a weighting agent. Use of the fluid while drilling allows bio-remediation of drill cuttings using land spreading, bioreactors, conventional composting or vermiculture composting. The resulting product, especially when vermicomposed, is potentially useful as a soil amendment or plant fertilizer material.
