Gravity driven reverse circulator tools are provided and methods of using same. One tool has nested pipes that when fully nested close a hole in one of the pipes, but when the drillstring is lifted, the pipes partially separate under the force of gravity to expose the hole. The other embodiment is similar, but the hole is hook shaped (hook on top as in a walking cane) and a protrusion from the other pipe fits in the hole. Thus, both lifting and rotation are needed open the tool.

Reverse circulator and method

A system and method for turning a well over to production. The method may include drilling a wellbore using a drillstring, casing the wellbore, fracturing a reservoir, drilling the wellbore to a plug back total depth using the drillstring to clean out the wellbore, and converting the drillstring from a drilling mode to a production mode.

System and method for turning well over to production

Disclosed are systems and methods for pressure testing coiled tubing (CT) in a well. A CT pressure testing device may include a CT connector for attaching to a CT segment and a pressure test housing defining a pressure chamber. A rod may extend through a top opening of the pressure test housing and through the CT connector to the severed end of the CT segment. A sealing plug coupled to a bottom end of the rod may create an interface between the CT connector and the CT segment. A force activator may apply a force to a top end of the rod, causing the rod to push the sealing plug into the CT segment and tighten the interface. A pump may pressurize the pressure chamber to perform a pressure test on the sealing plug. Accordingly, the CT pressure testing device may establish a well control barrier for the well.

Systems and methods of pressure testing coiled tubing

A system for making and using a ground product that includes one or more of: a reactor operated to react a guar split with a reagent at a reaction temperature in a range of 120&#xb0; F. to 180&#xb0; F. to form a guar derivative, and a treatment and transfer section for optionally treating the guar derivative and transferring the guar derivative to a co-grinder. The co-grinder is operably associated with a heated vacuum system and is operated to co-grind an acid with the guar derivative to form a ground product.

System for making and using a composition of matter

A delayed fin deployment wiper plug has a tubular body, which has a closed top and a piston therein. The piston is supported at one or more locations inside the tubular body by one or more sets of shear pins or spring clips or some equivalent device. The piston is connected to or abutted to a sleeve that covers an upper portion of the tubular body, containing therein one or more sets of deployable fins that are not exposed for use unless the piston is activated and raises the sleeve.

Delayed fin deployment wiper plug

A process for making and using a ground product that includes the steps of: reacting a guar split with propylene oxide at a reaction temperature in a range of 120&#xb0; F. to 180&#xb0; F. to form a guar derivative; and treating the guar derivative with at least one of washing and drying to form a resultant treated derivative. The process includes transferring the resultant treated derivative to a co-grinder operably associated with a heated vacuum system; and co-grinding the resultant treated derivative with a powdered carboxylic acid to form a ground product.

Process for making and using a composition of matter

By incorporating a dissolvable or degradable material into the wiper dart and/or float equipment, a fluid can be pumped during the cement phase (or spotted by other means) to begin degradation of the dissolvable material. Once the material is dissolved, a flow path is exposed, allowing communication to the backside or formation of the wellbore through the plug set and shoe track.
