| A bore hole is formed using an elongated, reversible rolling tube with inner and outer walls connected at the forward end by a rollover area, holding a central pipe. The area is positioned so ti projects into an underground formation, and drilling fluid is directed through the annulus between the inner wall and the pipe and then through the pipe. Driving fluid is directed through the annular space between the walls, so that the inner wall moves through the area to become the outer wall as the tube moves forward into the slurry of cuttings as the pipe is carried forward as a function of the movement of the area. The tube is e.g. of woven cloth, and the fluid may include a hot acid or basic aqueous or petroleum-based solution. | ||||||

| The present invention provides cross-linked fracture fluids that allow for reusing return water with no treatment, minimizing the environmental impact thereof and reducing the use of fresh water to very low levels to stimulate wells or re-stimulate wells stimulated in the past. Preparation and use methods of said fluids in fractured subterranean formations drilled by wells, based on return water, production water, sea water, fresh water and mixtures thereof, are provided. Fluids are basically composed of: return water, production water, sea water, fresh water and mixtures thereof present in a sufficient amount to moisten the gelling agent and to form a gellified aqueous agent; a gelling agent; an iron control agent; an alkaline buffer; a delayed cross-linking agent, and a rupture system to "break" the fluid and improve fracture cleaning. | ||||||

| A rotating control apparatus, comprising: an outer member; an inner member having a first sealing element and a second sealing element; said inner member, said first sealing element and said second sealing element rotatable relative to said outer member; a first cavity defined by said inner member, said first sealing element and said second sealing element; and said inner member having a port to said first cavity. Disclosed is also a method for drilling a wellbore in a formation with a fluid, comprising the steps of: casing a portion of the wellbore using a casing having a casing shoe; determining a casing shoe pressure; determining a formation fracture pressure; positioning a rotating control device with said casing; and drilling the wellbore at a fluid pressure calculated using the lesser of the casing shoe pressure and the formation fracture pressure. | ||||||

| By substantially eliminating the crushed zone surrounding a perforation tunnel and expelling debris created upon activation of a shaped charge with first and second successive explosive events, the need for surge flow associated with underbalanced perforating techniques is eliminated. The break down of the rock fabric at the tunnel tip, caused by the near-instantaneous overpressure generated within the tunnel, further creates substantially debris-free tunnels in conditions of limited or no underbalance as well as in conditions of overbalance. | ||||||

A measurement head for making X-ray measurements on drilling fluid includes an inner pipe (30) having a outlet (32) and an outer pipe (34) around the inner pipe. Drilling fluid is pumped through the outlet refreshing the fluid at the outlet. The pump is then stopped. A height sensor (42) is then used to measuring the height of a meniscus of drilling fluid at the outlet (32). An X-ray head (50) including an X-ray source (52) and an X-ray detector (54) is then moved into a reproducible position above the meniscus of fluid above the outlet. The height sensor (42) may be fixed to a movable cover (40), to the X-ray head (50) or to some other part of the measurement head.

| Pumping a pre-flush composition into a subterranean reservoir may contact at least a portion of non-polar material within a reservoir path. The pre-flush composition may have or include a polar fluid and at least one surfactant. The pre-flush composition may in situ form an in situ fluid in the reservoir path. The in situ formed fluid may include a portion of the non-polar material from the reservoir path, a polar phase from the polar fluid, and at least one surfactant. Pre-flushing the reservoir path may allow for greater hydrocarbon recovery when performing a subsequent operation as compared to an otherwise identical operation absent the pre-flushing the reservoir. | ||||||
