Abstract

The invention relates to methods for preparing aqueous solutions of mineral salts with a composition corresponding to that in equilibrium with solid rock minerals under the target conditions of the experiment. The technical result achieved by implementing the invention is to provide the possibility of obtaining a model of formation water with a composition closest to real formation water at target values of temperature and pressure, without the need for water sampling in the field. In accordance with the proposed method of preparation of the formation water model, a rock sample containing soluble hard skeleton minerals and/or salt deposits in the pore space, which was initially saturated with formation water and contains at least one area that has not been exposed to drilling fluid, is taken from the formation. The amount and composition of soluble sediments in the collected sample and the water saturation of the sample under reservoir conditions are determined. At least one internal region in the sample, not exposed to the drilling fluid, is selected and a three-dimensional digital model of the selected region is built, reflecting the pore structure and spatial arrangement of minerals. The water solubilization chemical reactions for all water-soluble minerals found in the sample are set. Numerical modeling of the initial saturation of the sample under study with water is carried out, taking into account the dissolution of minerals included in the sample at the required temperature and pressure until equilibrium is reached. The final ionic composition of the aqueous solution saturating the pore space of the numerical model after equilibrium is reached is determined, and the solution is prepared by dissolving the calculated amount of salts in the calculated amount of water while stirring. The resulting salt solution is brought to the required thermobaric conditions.

Abstract

A technique facilitates managed pressure drilling of a borehole. The technique utilizes a seal rotating system for managing pressure during a drilling operation. The seal rotating system has an elastomeric seal element which is rotatably mounted in the seal rotating system. When a drilling operation is to be performed, the seal rotating system may be deployed down into a rotating control device housing such that the elastomeric seal element is disposed within a packer, e.g. an elastomeric packer, which is rotatably mounted in the rotating control device housing. An actuator may be used to provide a controlled squeeze on the packer, thereby exerting an inward squeeze on the elastomeric seal element so as to maintain a suitable seal with a drill string extending therethrough. The seal rotating system may also include a load transfer member positioned to absorb loading due to wellbore pressure, thus reducing bearing loading.

Abstract

A technique facilitates application of increased force in various well applications while limiting the overall time period of the operation by automatically utilizing two modes of operation. In some well applications, the technique automatically applies increased force to facilitate shearing of a tubular product in a timely manner. By way of example, the system may be utilized to rapidly advance rams to the point of contact with the tubular product extending through well equipment, e.g. through a blowout preventer (BOP), and then to automatically shift to a slower advance but higher force mode. The higher force mode facilitates shearing of a variety of tubular products in a variety of well applications.

Abstract

Devices, systems, and methods are provided for a through-rotary centralizer for downhole operations. The through-rotary centralizer assists with centralizing a tool operating downhole, such as a bit. The through-rotary centralizer has a mandrel, a sleeve rotatably mounted around the mandrel, a floating hub slidably mounted around the sleeve, and centralizing arms mounted to the sleeve and floating hub. The centralizing arms extend to exert force against the inner wall of a tubular, such as wellbore casing, thereby providing stability to the downhole tool. Because the sleeve is rotatably mounted to the mandrel, the mandrel rotates within the sleeve and is able to transmit power or torque to the downhole tool, such as a bit. The centralizing arms are not required to rotate with the mandrel due to the rotatably mounted sleeve. A surface system may be used to control the position of the through-rotary centralizer.

Abstract

Methods and systems that configure a downhole tool disposed within a wellbore adjacent a reservoir to perform fluid sampling operations that draw live reservoir fluid from the reservoir into the downhole tool are described. The live reservoir fluid is at elevated pressure and temperature conditions of the reservoir. The live reservoir fluid is analyzed within the downhole tool to determine fluid properties of the live reservoir fluid. Interfacial tension of the live reservoir fluid can be determined or predicted from the fluid properties of the live reservoir fluid. The interfacial tension of the live reservoir fluid can be used to characterize and assess quality of the live reservoir fluid in substantially real-time. The characterization and assessment of the quality of the live reservoir fluid can be used to control the sampling operations or initiate downhole fluid analysis or sample collection for analysis of "clean" reservoir fluid of acceptable quality.

Abstract

A drill bit includes a bit insert. A bit body of the bit includes an insert cavity. The bit insert is inserted into the insert cavity. The bit insert is secured to the insert cavity, such as by braze or with a connection mechanism. The bit insert may be replaceable, thereby allowing a drilling operator to adjust the configuration of the bit based on which bit insert is used.

Abstract

A method for estimating a porosity of a rock sample includes acquiring a calibrated digital image of the rock sample, extracting color and texture features from the digital image of the rock sample, and estimating the porosity of the rock sample using a model to evaluate the extracted color features and texture features. The model is configured to correlate digital image color and texture features with porosity.

Abstract

Systems and methods are disclosed herein for improved debris collection within a wellbore. An example method can include inserting a tool into a wellbore, where the tool includes an input shaft, an auger shaft, and a collection chamber. The input shaft can be rotated in a first direction, causing rotation of the auger shaft. The rotation of the auger shaft conveys debris into the collection chamber. The input shaft can also be rotated in a second direction, which causes the auger shaft to retract within the collection chamber. The retraction of the auger shaft within the collection chamber prevents the debris from escaping the collection chamber. The tool can then be removed from the wellbore while preventing the collected debris from escaping the collection chamber.
