A method of assessing hole cleaning effectiveness of drilling comprises a) determining a mass of cuttings removed from a well wherein determining the mass of cuttings removed from a well comprises: i) measuring a total mass of fluid entering a well; ii) measuring a total mass of fluid exiting the well; and iii) determining a difference between the total mass of fluid exiting the well and total mass of fluid entering the well; b) determining a mass of rock excavated in the well; and c) determining a mass of cuttings remaining in the well wherein determining the mass of cuttings remaining in the well comprises: determining a difference between the determined mass of rock excavated in the well and the determined mass of cuttings removed from the well.

A method of controlling a direction of drilling of the drill string (110) used to form an opening in a subsurface formation (102), comprises varying a speed of the drill string during rotational drilling such that the drill string (110) is at a first speed during a first portion of the rotational cycle and at a second speed during a second portion of the rotational cycle wherein the first speed is higher than the second speed, and wherein operating at the second speed in the second portion of the rotational cycle causes the drill string to change the direction of drilling.

The present invention relates to wellbore surveillance system for obtaining fluid reservoir information data, such as the position and amount of gas, oil and/or water, while draining hydrocarbons from an oil or gas field via a casing in a wellbore in a formation, the casing having a vertical part near a top of the casing, the system comprising a first sensor for measuring a content of gas, oil and/or water in the formation, and a second sensor for measuring a content of gas, oil and/or water in the formation.

| 144 | METHOD OF DETERMINING BOREHOLE CONDITIONS FROM DISTRIBUTED MEASUREMENT DATA | EP09792557.2 | 2009-09-15 | EP2334905A2 | 2011-06-22 | EDWARDS, Stephen T.; COLEY, Christopher J.; EDWARDS, Michael L.; SHAFER, Donald F.; ALBERTY, Mark W. |
| Borehole conditions can be determined using distributed measurement data. Real time data measurements can be taken from sensors distributed along the length of a drill string to assess various conditions or properties of the borehole. In particular, the distributed data can be used for example, to track the progress of a chemical pill or also track the location of different types of borehole fluids, and also to determine the hole size or volume of the borehole. | ||||||

| A method of determining the erosion of a borehole or cavity (10) by providing a source of liquid inert gas, preferably nitrogen, placing the inert gas in a storage tank (20), and suspending the storage tank so that one may determine the actual weight of the nitrogen as it is withdrawn from the tank in liquid state. There is further provided hydraulic means (36, 38) for lifting or lowering the storage tanks suspended from a weight cell (50) as a tank is place into use or non-use. Further, the liquid nitrogen is pumped from the storage tank with the use of a reciprocating pump (56), and converted into gaseous nitrogen (in the state of 100<o>F,) and is injected into a borehole (10) or the like. The nitrogen gas is then allowed to flow under a certain pressure down the borehole, and due to the properties of nitrogen gas, the nitrogen interfaces at a horizontal plane (58) as it moves down the borehole. | ||||||
| 147 | DETERMINING STIMULATED RESERVOIR VOLUME FROM PASSIVE SEISMIC MONITORING | PCT/US2014035600 | 2014-04-28 | WO2014182479A2 | 2014-11-13 | NEUHAUS CARL W |
| A method for determining a stimulated rock volume includes determining a position of a plurality of seismic events from seismic signals recorded in response to pumping fracturing fluid into a formation penetrated by a wellbore. The signals generated by recording output of a plurality of seismic receivers disposed proximate a volume of the Earth's subsurface to be evaluated. A source mechanism of each seismic event is determined and is used to determine a fracture volume and orientation of a fracture associated with each seismic event. A volume of each fracture, beginning with fractures closest to a wellbore in which the fracturing fluid was pumped is subtracted from a total volume of proppant pumped with the fracture fluid until all proppant volume is associated with fractures. A stimulated rock volume is determined from the total volume of fractures associated with the volume of proppant pumped. | ||||||
