A desiccating module configured to be installed in a downhole tool is provided. The desiccating module includes a housing having a containment portion, and desiccant located in the containment portion of the housing capable of retaining moisture therein. The housing is configured to be retained in a downhole tool containing moisture sensitive electronics. The housing is configured to permit passage of moisture from outside the housing to the containment portion and to retain the desiccant within the containment portion. The desiccant have a retention capacity sufficient to hold a predetermined threshold amount of moisture.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.

The downhole tool comprises: (i) a housing connected with a collection chamber for receiving debris, the housing having an opening for collecting the debris from the petroleum well, the opening in fluid communication with the collection chamber through the housing; (ii) a rotatable shaft with transport blades arranged within the housing and extending from the opening to the collection chamber, the rotatable shaft configured for transporting debris from the opening to the collection chamber in operational use; (iii) an annular area defined between the rotatable shaft and an inner wall of the housing and (iv) a valve configured for keeping debris in the collection chamber. The valve is located within the housing between the opening and the collection chamber. The valve comprises a seal member with a movable part mounted in the annular area and around the rotatable shaft. The valve is opened when the movable part moves in direction of the collection chamber and is configured such that the movable part of the seal member is only movable in the direction towards the collection chamber when closed. The downhole tool provides a valve, which is easily opened, requiring a very small force, while providing a very good sealing effect when the seal member is closed.

This disclosure relates generally to pulling tools and, more particularly, to incorporating a bailer feature in pulling tools. A pulling tool may be provided that includes a housing. The pulling tool may further include a tool engagement assembly securing in the housing with a distal end of the tool engagement assembly extending from the housing for engagement with a well tool. The pulling tool may further include a bailer chamber formed in the tool engagement assembly and in fluid communication with an exterior of the pulling tool through an opening in the distal end of the tool engagement assembly. The pulling tool may further include a valve positioned in the opening of the tool engagement assembly.

A chemical capsule joint having a chemical capsule filled with a chemical that is to be released into a casing string to which the chemical capsule joint is deployed in a wellbore after an end of the chemical capsule joint if drilled up. The chemical capsule joint allows continuation of cementing operation until an end of the chemical capsule joint is drilled up to release the chemical from the chemical capsule in the chemical capsule joint. The chemical is then freed from the chemical capsule and allowed to leach into production fluids in the casing string to which the chemical capsule joint is deployed in a well bore.

A wellbore gauge cutter apparatus includes a sampling body defining a central recess extending from an inlet at a first end to an outlet at a second end. The apparatus further includes a gauge cutter connected to the sampling body configured to dislodge particles from an inner wall of a wellbore. The sampling body includes an inner wall defining the central recess, a hollow cylindrical divider having a central aperture, a first flow path defined in the central aperture of the hollow cylindrical divider, a second flow path defined between an outer wall of the hollow cylindrical divider and the inner wall of the sampling body, and a fluid permeable screen arranged in the first flow path or the second flow The fluid permeable screen is configured to collect a portion the particles dislodged by the gauge cutter.
