Abstract:
A method for determining drilling fluid losses or gains by providing a drilling fluid, measuring a plurality of supply parameters of the drilling fluid, delivering the drilling fluid to a subsurface drilling operation, the subsurface drilling operation providing a returns drilling fluid, measuring a plurality of returns parameters of the returns drilling fluid, and determining change in composition, or loss of or gain of drilling fluid from a comparison between the supply parameters and the returns parameters.
Abstract:
We disclose an apparatus and process for mini core in drilling samples accumulated in the cups by sample catcher. It allows the explorations to obtain high resolution Formation Evaluation on drilling cuttings samples. The process is assuming implementation of samples collected by Sample Catcher as the one described by author in patent U.S. Pat. No. 6,386,026 B1 May 14, 2002. The Mini Core apparatus consists of narrow cylinder with a piston. The thin wall cylinder is rotating by hand and pressed in to the cup with wet sample of drilling cuttings. The piston is placed after the desired depth of sample is reached and the vacuum is re-established. The core is pulled out from the cup and then squeezed out on the flat tray for horizontal analysis. The micro layering can be visually separated, before they are mixed as in conventional sample and the information is lost.
Abstract:
An apparatus and process for visual observation and measurement of aggregated, granular and floating or suspended particles samples, which are gravitationally separated is disclosed. The first part of apparatus is the horizontally focused binocular microscope with vertical positioning. The second part of the apparatus is the revolving test tube holder with vertical positioning and rubber ring for soft tube position fixing. The process is consisting in horizontal focusing on the visual sample analyzing it in liquid. The difference from conventional process of sample analyzing is that in vertical position the gravitationally separated fractions of the sample will be not disturbed during the analysis and study of the sample. This will make possible both to study the micro-granulometry samples under horizontally focused binocular microscope and to use different liquids for gravitational separation of particles and granules without contaminating the environments and degrading working conditions.
Abstract:
Floating bubble jar gas dryer include a container floating in glycol on top of input gas sample pipe. The gas flow pressure regulates the depth of sinking of the floating container in the drying liquid (glycol for water). Small holes at the bottom of the floating container disperse the gas into the liquid where the diffusion process absorbs the moisture from the gas sample.
Abstract:
An apparatus and process for measuring the granulometry separations in discrete media and unconsolidated sediments for relatively small sample quantities (5 cc containers of drilling cuffings) is disclosed. A small diameter glass tube may be filled with a small amount of sample, and water added. After shaking and placing it vertically, the larger, denser particles will settle near the bottom. Particle size will tend to decrease in size towards the top. Placing the tube near an array of sensors may perform a quantitative analysis such as sonic, gamma and optical sensing. One or more sensors are slowly moved past the tube and digitized readings be recorded. The collected readings are interpreted by the quantity and sizes of particles and by their distribution. The results may be presented in various ways and used to calculate the environmental index of energy of accumulation and to quantify the relative permeability of a potential reservoir.
Abstract:
An apparatus and method for analyzing the continuous flow of drilling cuttings in real time on a surface while drilling employs a set of sensors placed around an analyzer tube and main auger or within the main auger related to the formation with a defined space-time shift. The method includes measuring the sample to obtain specific properties related to physical and petrophysical parameters of this formation (radiation, resistivity, inductivity, density, elasticity, others). Obtained signals are conditioned and digitized in order to derive the desired discrimination in target properties, such as rock type, porosity, density, and oil saturation. An expanding auger, with a hollow end adapted to receive a sensor tube in which the sensors or sources may be placed, is adapted to rotate or circulate a discrete media about the sensors.
