An enrichment apparatus and process for enriching a hydrogen sulfide concentration in an acid gas stream to create a hydrogen sulfide rich stream for feed to a Claus. The enrichment apparatus comprises a hydrocarbon selective separation unit operable to separate the acid gas stream into a hydrocarbon rich stream and a purified acid gas stream, wherein the acid gas stream comprises hydrogen sulfide, carbon dioxide, and hydrocarbons, a hydrogen sulfide selective separation unit operable to separate the purified acid gas stream to create the hydrogen sulfide rich stream and a hydrogen sulfide lean stream, the hydrogen sulfide rich stream having a concentration of hydrogen sulfide, and the Claus unit operable to recover sulfur from the carbon dioxide lean stream. The enrichment apparatus can include a carbon dioxide selective separation unit in fluid communication with the hydrogen sulfide selective separation unit, operable to separate the hydrogen sulfide rich stream.


A dynamic demulsification system to facilitate the removal of water from oil for use in a gas-oil separation plant (GOSP) which has a dehydrator vessel in fluid communication with a desalter vessel which in turn is in fluid communication with a water/oil separator vessel includes the following system components:


A demulsification process for extracting surface active biochemical products from crude oil and its fractions when they are used as feedstock during biochemical productions utilizes subcritical/supercritical C02 as a proton pump. The process also includes a pH tuning step, thereby inducing demulsification and precipitation of biochemical products into the aqueous phase, but avoiding asphaltene precipitation by apriori addition of resinous solvents derived from crude oil or bioresources. The biochemical products are then extracted from the aqueous phase via temperature change or some other technique.


An enrichment apparatus and process for enriching a hydrogen sulfide concentration in an acid gas stream (10) to create a hydrogen sulfide rich stream for feed to a Claus. The enrichment apparatus comprises a hydrocarbon selective separation unit (102) operable to separate the acid gas stream into a hydrocarbon rich stream (14) and a purified acid gas stream (12), wherein the acid gas stream comprises hydrogen sulfide, carbon dioxide, and hydrocarbons, a hydrogen sulfide selective separation unit (106) operable to separate the purified acid gas stream (12) to create the hydrogen sulfide rich stream (18) and a hydrogen sulfide lean stream (16), the hydrogen sulfide rich stream (18) having a concentration of hydrogen sulfide, and the Claus unit (200) operable to recover sulfur (80) from the hydrogen sulfide rich stream (18). The enrichment apparatus can include a carbon dioxide selective separation unit (108) in fluid communication with the hydrogen sulfide selective separation unit (106), operable to separate the hydrogen sulfide rich stream (18).


A well completion system (10) includes tubing (16), and packers (19) that seal the annulus (24) of the well outside the tubing (16). The packers (19) are spaced to define voids in the annulus (24) that are substantially free from hydrostatic pressure. Also included are hollow sleeve valves (18) having upper and lower sealing elements (28, 30), and that have closed and open positions. Each sleeve valve (18) is positioned within the tubing (16) at a depth corresponding to a void in the annulus (24). Ports (26) extend through the sleeve valve (18) and tubing (16), so that when the sleeve valve (18) is closed, the port is closed, and when the sleeve valve (18) is open, the port is open. Also included is a sampling tool (32) having top and bottom sealing elements (34, 36), the bottom sealing element (36) for engaging the lower sealing element (30) of a sleeve valve (18), and the top sealing element (34) for engaging the upper sealing element (28) of the sleeve valve (18) when the sleeve valve (18) is open.

A downhole self-isolating wellbore drilling system to pulverize formation cuttings which includes a cutting grinder tool (102) and an isolation tool (110). The cutting grinder tool (102) can be attached to a drill string (104) uphole relative to a drill bit (106) attached to a downhole end of the drill string (104). The cutting grinder tool (102) can receive and pulverize formation cuttings resulting from drilling a formation using the drill bit (106). The isolation tool (110) can be attached to the drill string (104) uphole relative to the cutting grinder tool (102). The isolation tool (110) can control flow of the pulverized formation cuttings mixed with a drilling mud uphole through the drill string (104).


The present disclosure describes methods and systems, including computer-implemented methods, computer-program products, and computer systems, for providing 360-degree well core sample photo image integration, calibration, and interpretation for modeling of reservoir formations and lithofacies distribution. One computer-implemented method includes receiving a 360-degree well core sample photo image, geospatially anchoring, by a computer, the received 360-degree well core sample photo image, decomposing, by a computer, the geospatially-anchored 360-degree well core sample photo image into a color numerical array, transforming, by a computer, the color numerical array into a formation image log, calibrating, by a computer, the formation image log for consistency with additionally available data, and generating, by a computer, 3D lithofacies interpretation and prediction data using the formation image log.


Some examples of pyrolysis to determine hydrocarbon expulsion efficiency of hydrocarbon source rock can be implemented by performing an open system pyrolysis of a hydrocarbon source rock sample obtained from a natural system. Sample includes hydrocarbon source rocks having an equivalent spherical diameter of substantially at least one centimeter. After the open system pyrolysis, the sample can be crushed and thermally vaporized. A hydrocarbon expulsion efficiency of hydrocarbon source rock in the natural system can be determined based on hydrocarbons recovered in response to the open system pyrolysis and in response to the crushing and thermal vaporization.

Wireless power transmission to downhole well installations is provided using acoustic guided Lamb waves and a tubular conduit (production tubing, casing) as the power transmission medium. A phased array of acoustic transmitters is present at the transmitting end (surface) and an array of acoustic receivers at the receiving end (downhole). Both transmitter and receiver arrays are coupled to the tubular conduit. Beamforming techniques are used along with power amplifiers to generate directional, high power and low frequency acoustic guided Lamb waves along the wellbore to transmit power over long distances. A downhole multi-channel acoustic energy collecting system receives the transmitted acoustic signal, and generates electrical power and stores the power in downhole electrical power storage. This power is used to operate downhole well equipment including sensing, control and telemetry devices.
