Benefits of technology

[0006]One aspect of the present invention is an apparatus for collecting samples of drill cuttings using vacuum assisted cuttings transfer from a shale shaker to a sample jar, the apparatus comprising a movable inlet port, a suction line to transfer cuttings from the inlet port to a discharge chamber, the suction line being adjustable to control surface moisture of the drill cuttings. The apparatus may further comprise a set of pneumatic actuators to control position of the inlet port and the sample jar and an electronics unit placed in an explosion-proof enclosure. The apparatus may comprise a vacuum control unit including an air operated (

Embodiment Construction

[0014]FIG. 1 illustrates a conceptual view of the apparatus of the present invention. The apparatus comprises a cuttings transfer unit 100 including a cuttings inlet port 103 to acquire cuttings from the surface of a shaker 102 or, alternatively, from a cuttings receiving board (the cuttings entering the inlet port are shown at 104), a cuttings inlet port displacement actuator 106 to scan the surface of the shake during the cuttings acquisition from the shaker surface, and an adjustable suction line 109 (flexible, with adjustable length) to transfer cuttings from the inlet port to the discharge chamber 110. The adjustable suction line is also used to substantially eliminate (or reduce as needed) moisture on the surface of the cuttings fragments. The moisture is reduced during transferring cutting in the suction line. The length of the line controls the level of the moisture reduction. The moisture control is required for some measurements on drill cutting, for example, for nuclear ...

Abstract

An apparatus and a method for surface logging include a vacuum assisted transfer of drill cuttings from a shale shaker to sample jars. The cuttings samples are used for measurements to characterize formations in which a wellbore is drilled. The apparatus has an adjustable suction line that can be used to control moisture on the surface of the drill cuttings fragments. The method includes an automated sample collection and a high throughput sample treatment (e.g., washing or/and a controllable drying) to increase value of measurements.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is related to a provisional patent application claiming the benefit 35 USC 119(e). The provisional patent application number is U.S. Pat. No. 62 / 696,821; filing date is Jul. 11, 2018.BACKGROUND OF THE INVENTIONField of the Invention[0002]This invention is related to an automated process of collecting drill cuttings at a shale shaker during the drilling operation. More specifically, the invention teaches apparatus and methods for fast automated sampling and preparation of the drill cuttings to enable continuous evaluation of petrophysical properties (e.g., properties evaluated based on natural gamma spectroscopy and nuclear magnetic resonance relaxometry) of the earth formations while drilling an oil well.Background Art[0003]Cost efficient drilling operation would greatly benefit from lower cost and high throughput quantitative data acquisition to evaluate the rock formations being drilled. Advanced mud logging including m...
