Well economics were viewed to assess and justify a poor boy gas lift/ plunger lift install on the potential candidate. WI and NRI were taken into account as well. It was found that TRE maintains a 93.1 % WI on the plunger candidate with a NRI of 69.8 %. The NRI to WI ratio is found to be 75 %. Common NRI/WI ratios range from 75% to 87.5%, so this well would fall at the lower end of the spectrum. The candidate well has a lot of problems with salt. It is the only well with a packer in the area so water and soap cannot be pumped down the backside under current conditions, however, the packer is removable. Field operators are hesitant to apply soap sticks as an intermediate step because of the manner in which salt build up breaks loose in the …show more content…
The well (BOE 16-16) is deep and it is thought that the plunger will need extra assistance to operate properly. It is important to note that there is a high pressure line next to the well. The current set up will allow for an easier and cheaper poor boy gas lift installation. In addition, a poor boy gas lift system will allow chemical and foamer injection into the well as needed. These injections would help correct the salt build up issues that the candidate well experiences. The idea is to try a poor boy gas lift before installing a plunger lift. This may be a case where a plunger lift is not needed in conjunction with a poor boy gas lift. Judging from Cygnet and discussions with field personnel, swabbing typically occurs every couple of weeks on the plunger candidate but has decreased to once a month since March of 2015. See Fig. 1 for current Cygnet data. The current cost for swabbing this well is about $4,000 monthly. Additionally, the well is offline and not producing during these treatment and swabbing periods, which amounts to 1-3 days per month. Cygnet analytics suggest shut in times of 24 to 72 hours each time swabbing occurs. Each time shut-ins occur on the candidate the field operations say that it becomes harder to get the well started again. It is thought that these issues further compound the monthly cost of maintaining this well at its current

If the Permittee is unable to complete work within the specified time period, the Permittee may provide an alternative schedule and shall obtain Director’s written approval. Injection operations shall not resume until the well has successfully demonstrated mechanical integrity and the Director has provided written approval to recommence injection.
Once the well reaches the right depth, it turns right or left and becomes horizontal. This is called the kick off point. The horizontal section can span anywhere from 1,000 to 6,000 feet. The drill is removed but the surrounding steel casing remains. These steel casings are meant to protect the groundwater and the surrounding area from any potential leakage during the fracking process. Down at the horizontal section of the well, little holes are punctured through the steel in thousands of spots. Then, a water solution is pumped at a extremely high pressure down the well. This causes tons of cracks and fissures in the rock. Additives and sand in the water mixture hold the cracks open, allowing oil to escape and be brought up to the surface.
The short story “The Death of Schillinger” was a story about a First Sergeant whom ruled over labor sector ‘D,’ a laboring portion of Birkenau which was formally known as the Auschwitz extermination camp. Schillinger was a short stocky man and was truly evil at his essence; “He visited the crematoria regularly and liked to watch people being shoved into the gas chambers.” (pp.144) One day in August of 1943, the SS were unloading a transport and preparing to load stripped Jews into the gas chambers. However, before this could be done Schillinger took a liking to one of the nude women and grabbed her out of line; she threw gravel in his eyes,
When steam is injected to the formation a steam chamber around the well is created [3]. The pressure of the steam should be lower than the fracture pressure of the rock mass to prevent the deflection of the rock [4]. Steam injection will go on for months during which the steam chamber expands and the viscosity of the bitumen decreases. This will cause the bitumen to flow down under gravity towards the production well. The produced oil is then pumped to the surface. Surface facilities are then used to separate the water
Well data were compiled using the New Mexico Office of the State Engineer’s Water Resources website Point of Diversion shapefile (http://www.ose.state.nm.us/GIS/geospatial_data.php). The shapefile was imported into GIS and the data were sorted by depth (>100 feet) and the remaining wells were further investigated by direct contact with the land owner. If the well
Ever been on a gas scooter? I have. It was by the most traumatic experience I have ever dealt with. Falling off not knowing the gas scooter didn’t have any brakes and hitting a car then falling off. Well, that was by far the most memorable day in my life. Ive never been in so much pain than that day, the worst experience ever.
To start with, a competitive analysis was completed to help easily identify plunger candidates according to well records. Phone calls were made to field personnel in order to confirm data collected from well records. It is important to note that some information in office records did not match current well conditions in the field. For example, existing office records suggested a plunger was currently installed on some wells; however, field operations confirmed that plungers had been removed. These differences were accounted for in the competitive analysis generated when field information was obtained via phone conversations with Mark Miller and Mike Day.
This report describes the basic principles of hydraulic fracturing pumps, and the instrumentation related to operate the process safely and successfully. Throughout the report, it will discuss different types of pumps used, the control systems needed for ease of operation. Also, the hydraulic fracturing process will be discussed.
At present, Lucas Energy (is a publicly traded oil and gas company) collects the water produced by the wells at it’s Stratford Pilot Project in lined storage dams on site. Some have a high salt content (greater than 5000 parts per million) which is stored separately from the remainder ( which have a lower salt content). Lucas has approval from the Department of Primary Industries (DPI) to use the low content salt water for irrigation under certain conditions which ensures that there is no detrimental impact on the condition of local soils and groundwater. The water is also used during daily operation for activities such as dust suppression and drilling.
Shock waves can be created using explosives, thumper trucks, or compressed air guns. The returning waves are measured by hydrophones that can record the waves underwater. Results are then analyzed for signs of oil. Promising signs of oil traps are marked on a map. Once oil has been located, drilling wells are constructed around the oil deposit. When the well is complete, extraction begins. Acid is pumped into the wells and out the perforators, which are vein-like channels that branch into the layers of rock. The acid dissolves the limestone, then oil flows through the perforators and into the well. If there is sandstone surrounding the oil instead of limestone, a fluid containing proppants (sand particles) is pumped through the perforators. This fluid creates pressure that fractures the sandstone and allows oil to flow into the well without the perforator closing back up. Sometimes, the oil is too heavy to flow into the well. Hot steam is introduced to the perforators to thin the oil, and create more pressure to push the oil through the perforator. This process is called enhanced oil recovery (Freudenrich, Strickland, n.d.). Offshore oil drilling is very risky, because if an oil well is leaks, thousands of gallons of oil will flood the surrounding water.
The vertical well is then encased in steel and/or cement to ensure the well doesn 't run the risk of leaking into any groundwater. Once the vertical well reaches the deep layer of rock where natural gas or oil exists, the well curves about 90 degrees and begins drilling horizontally along that
Later, horizontally drilled wells were first noticed in Texas in the 1930s. The technology has been endurably matured and developed; and in 1980s, it shows like a standard industry practice. Subsequently in 1990s, Barnett shale made it enabled to get the shape in economically viable for both horizontal drilling and hydraulic fracturing technologies. It seems that fracking has an enormous economic
Use SCBEU units at bitumen and oil sand sites to ‘extract and upgrade’ at the site. The SCBEU unit would replace much of the current oil sand solvent extraction washing process and does not require solvent recovery or disposal (4,5,9,10,11,12,25,28). [This case will be developed in this proposal using the Arroyo Grande Bitumen site near Edna, CA. (26,27,28)]
The purpose of this report is to discuss estimated ultimate reserves of gas, oil, and NGL. Also, to discuss the drilling and development costs per well for the Eagle Ford shale, the Bakken shale, the Marcellus shale, and the Tuscaloosa Marine shale. Next, I will comment on the first exploratory well and the company responsible for the discovery well. I will then discuss the
