(2009-05-15)Many open-hole acid treatments are being conducted by pumping acid through jetting ports placed at the end of coiled tubing or drill pipe. The filter-cake on the bore-hole is broken by the jet; the acid-soluble material ...
-
(2012-07-16)In the Middle East, extended reach horizontal wells (on the order of 25,000 feet of horizontal displacement) are commonly acid stimulated by jetting acid out of drill pipe. The acid is jetted onto the face of the openhole ...
-
(2014-04-28)Seawater is the only viable water source for many offshore wells with dolomite formations. For these wells it is important to use compatible fluids when stimulating to avoid damaging the formation with calcium sulfate ...
-
(2015-03-25)Hydrochloric acid (HCl) is the most commonly used stimulation fluid for high-temperature wells drilled in carbonate reservoirs due to its high dissolving power and low cost. However, the high corrosion rate of HCl on well ...
-
(2012-10-19)Mud acid, which is composed of HCl and HF, is commonly used to remove the formation damage in sandstone reservoirs. However, many problems are associated with HCl, especially at high temperatures. Formic-HF acids have ...
-
(2017-07-11)AlCl₃ has been long used as a retarding agent for mud acid, its applications studied in the lab and tested in the field. The theory and mechanism of AlCl₃ retardation have been investigated in many projects involving mud ...
-
(2015-04-23)Acoustic sensing technology has a long history of being implemented in the oil and gas industry; from the early days of measuring seismic activity to determine oil and gas reserve to the present day technology such as fiber ...
-
(2014-09-30)Operation and service companies in the oil and gas industry have recently deployed Distributed Acoustic Sensing (DAS) technology as a hydraulic fracturing diagnostic tool. However the uses of DAS technology are limited to ...
-
(2016-11-28)This dissertation introduces a new method to create adaptive mesh refinement and coarsening in compositional reservoir simulation. The methodology targets individual cells for refinement based on forecasted compositional ...
-
(Texas A&M University, 2006-08-16)A global steady increase of energy consumption coupled with the decline of conventional oil resources points to a more aggressive exploitation of heavy oil. Heavy oil is a major source of energy in this century with a ...
-
(2017-08-25)This thesis formalizes and extends a prior work in the effort to create explicit solutions to directly compute the effects of wellbore storage and phase redistribution (phase redistribution is treated as a special case of ...
-
(2010-01-16)The supply and demand situation is crucial for the oil and gas industry during the first half of the 21st century. For the future, we will see two trends going in opposite directions: a decline in discoveries of conventional ...
-
(2010-01-16)With the rapidly increasing demand for energy and the increasing prices for oil and gas, the role of unconventional gas reservoirs (UGRs) as energy sources is becoming more important throughout the world. Because of high ...
-
(2016-05-05)After closure analysis (ACA) of a fracture calibration test designed to provide closure pressure and the fracturing fluid leak-off coefficient can provide estimates for formation permeability and pressure if radial flow ...
-
(2013-08-13)Since the 1980’s horizontal drilling has been a game-changing technology as it allowed the oil and gas industry to produce from reservoirs previously considered marginal or uneconomic. However, while it is considered a ...
-
(Texas A&M University, 2006-04-12)When the reservoir pressure is decreased below dew point pressure of the gas near the wellbore, gas-condensate wells start to decrease production because condensate is separated from the gas around the wellbore causing a ...
-
(2012-07-16)In gas-condensate reservoirs, production rate starts to decrease when retrograde condensation occurs. As the bottomhole pressure drops below the dewpoint, gascondensate and water buildup impede flow of gas to the surface. ...
-
(2010-07-14)Diesel engines operating the rig pose the problems of low efficiency and large amount of emissions. In addition the rig power requirements vary a lot with time and ongoing operation. Therefore it is in the best interest ...
-
(2015-06-05)In this work, Babu and Odeh’s model for estimating flow rate from partially penetrating systems is studied. A VBA code is written in order to simulate the model and its results are compared against simulations using Eclipse ...
-
(2011-02-22)Water production is a challenge in production operations because it is generally costly to produce, treat, and it can hamper hydrocarbon production. This is especially true for gas wells in unconventional reservoirs like ...
