| 20110036569 | DOWN-HOLE TRANSMITTER SYSTEM, METHOD OF INDUCING A TRANSIENT ELECTROMAGNETIC FIELD IN AN EARTH FORMATION, METHOD OF OBTAINING A TRANSIENT ELECTROMAGNETIC RESPONSE SIGNAL, AND METHOD OF PRODUCING A HYDROCARBON FLUID A down-hole tool provided with a transmitter system for inducing a transient electromagnetic field in an earth formation has an induction coil with a number of windings to generate essentially a magnetic dipole field. The number of windings is divided into two or more g... | 02/17/2011 |
| 20090288823 | Efficient Multiple Prediction In Two and Three Dimensions A method is disclosed that uses (a) source-receiver reciprocity and (b) a method such as ISR DMO (U.S. Patent Application Publication No. 2006/0098529) that allows reconstruction of densely sampled gathers at arbitrary surface locations, to efficiently predict multiple ... | 11/26/2009 |
| 20090250211 | Refracture-Candidate Evaluation and Stimulation Methods Quantitative refracture diagnostic and fracture-injection/falloff models may be used in methods for oil and gas subsurface formation evaluation techniques. More particularly, such methods may be used to select candidate wells and well candidate layers for stimulation tr... | 10/08/2009 |
| 20090133870 | Method for Phase and Amplitude Correction in Controlled Source Electromagnetic Survey Data The method for correcting the phase of measured electric signals or magnetic signals of field data from a controlled source electromagnetic survey (CSES) by comparing the measured field data corresponding to a selected frequency to the simulated data for various signal ... | 05/28/2009 |
| 20090133871 | DRILLING, PERFORATING AND FORMATION ANALYSIS A system and method of drilling and/or perforating uses a laser beam to remove material, such as to perforate the casing, cement and formation or drill a well bore. The system and method can further or alternately encompass material analysis that can be performed withou... | 05/28/2009 |
| 20090120636 | Method for performing controlled source electomagnetic surveying with multiple transmitters Method for separating responses of multiple transmitters m a controlled source electromagnetic survey by using mutually orthogonal transmitter waveforms and transforming the combined response to the frequency domain (144) The mutual orthogonality can be based dis... | 05/14/2009 |
| 20090114387 | METHODS FOR IDENTIFYING COMPOUNDS USEFUL FOR PRODUCING HEAVY OILS FROM UNDERGROUND RESERVOIRS Described herein are methods for identifying compounds useful for producing heavy oil from an underground reservoir. The methods facilitate the development of chemicals with improved physicochemical features. The methods generally involve first identifying a physicochem... | 05/07/2009 |
| 20090000784 | Method for oil sand exploration and development The invention provides a method of locating, in terrain containing oil sand deposits and also containing shale, clean oil sands deposits (i.e. those not containing significant shale) which are large enough for economic exploitation. The method includes flying a high sen... | 01/01/2009 |
| 20070256832 | METHOD OF ANALYZING A SUBTERRANEAN FORMATION AND METHOD OF PRODUCING A MINERAL HYDROCARBON FLUID FROM THE FORMATION Method of analyzing a subterranean formation traversed by a wellbore. The method uses a tool comprising a transmitter antenna and a receiver antenna, the subterranean formation comprising one or more formation layers. The tool is suspended inside the wellbore, and one o... | 11/08/2007 |
